Mobile App Development Companies in USA (2025)

In 2025 and the upcoming days, startups and mid-level or large companies are moving to the next step of technical advancement with data-driven operations that can automate their work and save costs through the use of AI technology. For this reason, the demand for hiring AI developers and machine learning experts is growing fast. For startup companies, hiring full-time, in-house AI engineers is not always a good option. Offshore AI engineers are a good option for startups and mid-level software companies. That's where the Machine Learning (ML) team extension comes in. Team extension helps companies grow their current development team by adding skilled people like an AI developer for hire, without needing to hire them full-time. It’s a smart way to get expert help for your project without long-term commitments. 

In this article, we’ll explain what ML team extension means, how it works step by step, and why it can be a better choice than hiring in-house employees and how you can scale your AI project.

What Is Machine Learning Team Extension?

Team extension means adding skilled external ML engineers or AI experts to your existing tech team to support your current or upcoming AI project. These experts are usually from specialized AI development companies and work alongside your in-house developers.

Instead of spending a lot of time and money to hire full-time employees, you can quickly hire dedicated machine learning developers to fill the skill gaps and finish your project faster. This way works best when you need help for a short time or when you’re trying out a new AI solution.

Who Is an Artificial Intelligence Specialist?

An Artificial Intelligence specialist is someone who is an expert at building, designing, and managing systems and solving complex problems like humans do. These are called AI developers or AI engineers. They closely work with many AI elements or AI models, machine learning (ML), natural language processing systems, and create many AI tools that can even learn, think, or even talk. Their initial roles are not just coding—they train machines to make decisions based on data. Now in this era, many organizations hire AI developers because these specialists improve customer experience, automate regular tasks, increase efficiency, and get a higher return.

Why Businesses Need AI Experts?

In 2025, technology is changing very quickly changing and the use of AI technology is increasing and the use of AI technology improving their efficiency and increasing their work capability. From an AI agent to AI chatbots that AI will change the operation of companies and business flow

That’s why more companies are trying to hire AI experts or hire artificial intelligence engineers who can build custom AI solutions tailored to their needs. AI helps with things like:

• Automating customer service
• Forecasting Sales trends and terms
• Increase decision-making through the use of data
• increases product demand
• Detecting fraud or risks

Without skilled developers, these smart systems can’t function. So, the demand to hire AI engineers or AI developers for hire is growing very fast.

What Can AI Developers For Hire Achieve?

When you hire AI developers, you’re not just getting a coder—you’re getting someone who can help your business grow. These AI engineers for hire can create smart software that learns from users and becomes better over time. Some things an AI developer can build for you:

• AI chatbot for your website or app
• Smart data analysis tools that show trends or risks
• Personalized content engines
• Generative AI systems like image or text creators
• Intelligent assistants for internal tasks

Businesses often hire dedicated machine learning developers or even freelance AI developers for flexible projects. Whether you’re building something from scratch or adding AI to your current system, these experts guide your entire development process.

How To Find AI Developers For Hire: Direct Search vs. Remote Platforms

Finding the right talent is crucial for any sector of jobs. Here, finding the right software engineer is crucial for many companies. Finding the right and perfect AI developer for hire depends on various factors like specific project needs, budget, and project timeline. There are two ways you can use: the first one is direct hiring, and the other one is using remote platforms.

Direct Search (In-House Hiring)

• You can hire AI developers or hire artificial intelligence engineers through job portals, tech events, or referrals.
  This works well for companies that need a full-time expert.
  However, it often comes with a higher cost to hire and a longer recruitment time.

Remote Platforms (Freelance or Offshore Hiring)

• Many businesses now hire remote AI developers or hire dedicated machine learning developers through platforms like Toptal, Upwork, or AI talent networks.
• Remote hiring is perfect for short-term or scalable AI projects.
• You can easily hire generative AI developers, hire AI/ML developers, or freelance AI engineers from anywhere in the world.

Why Ontik Technology Stands Out

If you want trusted and skilled AI developers for hire, then Ontik Technology is a smart option:

• Their AI and ML engineers are great at solving real-life complex business problems.
• Ontik’s team can help you build custom AI solutions from the beginning or add them to the systems you already use.
• Whether you need to hire an AI expert, hire a machine learning developer, or hire an AI engineer, Ontik gives quick and flexible support.
• It’s a perfect choice for startups and growing businesses that want to work better and faster with the help of AI technologies.
  

With a flexible way of working and a strong record of success, Ontik is the right partner for any business ready to grow using the power of AI and ML.

How Machine Learning Team Extension Works

Team extension is simple but powerful. Here’s how the process usually goes:

1. Define Your Needs

You start by identifying the skills or expertise you’re missing. Do you need someone who can work on AI model training? Or maybe a generative AI engineer to build content creation tools? List your project requirements and technical goals.

2. Find the Right Talent

Next, you connect with an AI development company or talent platform to hire AI/ML developers. These could be remote AI developers, freelance AI engineers, or full-time dedicated resources.

3. Integration With Your Team

Once selected, the new developers join your current development team. They work as your internal members do — attending meetings, reporting to your managers, and following your development process.

4. Project Execution

The extended team works on specific tasks, like custom AI algorithms, model tuning, or full-scale AI application development. Since they’re already experienced, they adapt fast and focus on delivery.

5. Scaling or Transitioning

Once the project is complete, you can scale the team up or down based on need, something that’s hard to do with full-time employees.

Why Use ML Team Extension?

Here are the main reasons businesses choose to extend their ML team instead of hiring in-house:

Speed

Hiring an AI engineer for hire is much faster than recruiting full-time staff. The market for skilled AI professionals is tight. Team extension lets you hire ML developers in days, not months.

Flexibility

You can hire AI experts only when you need them. Once your AI project is complete, there's no long-term commitment.

Lower Costs

Hiring in-house comes with hidden costs like onboarding, benefits, and tools. With extension, you only pay for what you need. This is perfect for startups that need affordable AI developers.

Access to Global Talent

Team extension opens the door to offshore AI developers and remote AI engineers, giving you access to the best — not just the closest — talent.

Fills Skill Gaps

Not all teams are ready for deep ML tasks. With team extension, you can hire a machine learning expert to guide or complement your existing team’s skills.

When Is Team Extension Better Than Hiring In-House?

Hiring a full-time team isn’t always the best move—especially for fast-growing businesses or startups. Here’s when choosing ML team extension makes more sense:

1. You Need a Quick MVP

Want to launch fast? Don’t spend months hiring full-time staff. You can hire dedicated machine learning developers for a short time and build your MVP quickly. This saves time, money, and gets you to market faster.

2. You Need Specific AI Skills

Need to work on generative AI but your team doesn’t have that skill? No problem. Just hire generative AI developers or a trusted AI developer for hire who already knows the tools and tech.

3. You’re Growing Fast

As your project scales, speed is key. You can’t always wait to recruit and train people. With remote AI developers, you get expert help right away and keep moving without delays.

4. You’re on a Budget

Startups and mid-sized businesses often need results without high costs. With team extension, you can hire artificial intelligence developers from global regions where pricing is more flexible—without losing quality.

5. You’re Just Starting With AI

New to AI? You don’t need a full-time hire. You can test ideas and build small solutions by bringing in a freelance AI developer or AI expert for a short project. It’s low-risk and smart.

Real Use Cases

Startup Launching an AI Chatbot: Lazychat

The Challenge

Customer service teams often face high pressure to respond faster, around the clock. Startups and growing businesses need a large customer support team, so they require a large group of people to respond to customer queries at the same time. A large number of queries and replying to all of the messages at once is not easy. For this, Ontik recognized this gap and set out to build a smart solution—an AI support agent that can deliver real-time responses without human intervention.

The Solution

Ontik designed and developed LazyChat, an AI customer support agent that feels human, works 24/7, and plugs seamlessly into any business website or platform. It’s not just a chatbot—it’s a context-aware AI agent trained on your brand’s unique data.

Their internal team included experienced AI developers, AI engineers for hire, and cloud-ready AI talent who specialize in AI-powered SaaS products. Instead of relying on basic automation, LazyChat was developed using advanced machine learning models and natural language understanding (NLU) to provide accurate, human-like responses.

How It Works

LazyChat can be integrated into any website in minutes. Businesses simply upload documents or link their knowledge base, and the AI agent starts learning immediately. Ontik also offers dedicated AI developer support to help clients integrate AI into their existing apps for a fully branded experience.

Key Features

• Real-time smart AI chat agent
• Trained with your own company data
• Integrates with websites and CRMs

Why We Needed a Clear Framework for AI Engineers

At Ontik Technology, as we grew our applied AI and machine learning practice, we faced a challenge many companies know well:

How do we clearly define what an AI Engineer truly is—not just in theory, but in daily work, model development, and production deployment?

Across the industry, AI roles often adapt to specific projects or the unique strengths of individuals. While this flexibility can be helpful, it often results in vague job expectations and unclear career paths. Without a solid framework, it’s tough to support engineers’ growth, evaluate their skills objectively, or prepare them to deliver production-quality AI systems.

We realized we needed a practical, delivery-driven AI engineer career framework—one that reflects the full machine learning lifecycle and real-world AI system delivery, especially in fast-moving startups or product teams.

It’s about:

• Not just building models, but building and deploying robust ML pipelines that run reliably in production.
  
• Not just writing code, but designing scalable, maintainable AI infrastructure.
  
• Not just chasing accuracy numbers, but ensuring reproducibility, latency optimization, drift detection, and other key MLOps practices.
  

Our Perspective: AI Engineering is More Than Just Using Pre-Trained Models

Using GPT APIs or building workflows with pre-trained large language models is valuable work, but in our view, that belongs more to AI solution development.

True AI Engineers go a step deeper.

They understand the fundamentals of building models from scratch. They write modular, clean, and testable code. They think carefully about reproducibility, latency, drift detection, model versioning, and production readiness.

They don’t just plug in pre-trained models—they design and build AI systems end-to-end, often starting from raw data, through model training, tuning, and integration into scalable applications.

Their work brings together multiple key areas:

• Data engineering, which involves preparing and transforming large datasets to make them usable and reliable for modeling.
  
• Model building, where they design, train, and fine-tune machine learning and deep learning models—often building them from scratch to solve specific problems.
• API development for models, creating interfaces that allow other systems or applications to interact seamlessly with the AI models in production.
  
• MLOps and system integration, focused on deploying models into production, setting up monitoring to catch issues like data drift, and maintaining the AI systems to ensure they perform reliably over time.

This comprehensive approach ensures AI solutions aren’t just experiments—they are real, scalable, and maintainable machine learning systems.

The AI Engineer Career Ladder: From Intern to Lead

We designed a career ladder to help AI professionals grow and companies to set clear expectations. This ladder includes six levels, each with distinct roles, responsibilities, and goals.

1. AI Intern

Focus: Learn the basics of data preprocessing, scripting, and simple model building.

Key skills:

• Python, pandas, NumPy
• Simple models (like logistic regression)

Why This Framework Matters

At Ontik Technology, having a clear, transparent AI engineer framework helps us:

• Define roles and responsibilities clearly, making career paths measurable and fair.
• Guide structured mentorship and learning opportunities across the team.
• Align technical maturity with real project delivery needs.
• Separate AI solution development (like prompt engineering with LLMs) from core model engineering and MLOps.
• Build scalable ML pipelines and maintainable AI infrastructure grounded in real-world best practices.
  

Let’s Build the AI Engineering Ecosystem — Together

This framework reflects how AI and machine learning systems are truly built and delivered—from data collection and model building to deployment and ongoing monitoring. It’s not a rigid rulebook, but a practical starting point designed to spark conversation, alignment, and shared learning.

Our goal is to build a community that:

• Defines what it means to be a true AI Engineer—with clarity, structure, and a strong focus on delivery.
  
• Nurtures the next generation of machine learning talent.
  
• Builds sustainable, robust AI ecosystems in Bangladesh and beyond.
  

If you’re involved in machine learning engineering, AI model development, building MLOps pipelines, or leading AI teams, this framework offers practical guidance to:

• Clarify roles and expectations,
  
• Improve collaboration between data scientists, engineers, and DevOps,
  
• Deliver reliable, scalable AI applications that truly add value.
  

We see this as a living framework—one that can be continually improved with input from engineers, leaders, and teams working on real-world AI projects. As the AI ecosystem in Bangladesh and beyond grows rapidly, creating shared language and clear expectations will help all of us raise the bar for AI engineering.

We welcome your feedback, suggestions, and collaboration to refine this framework further. Together, we can shape a stronger, more structured, and delivery-focused AI engineering culture—building scalable, robust AI systems that make a real impact.
