Artificial Intelligence (AI) and Machine Learning (ML) aren’t just tech trends — they’re reshaping how we approach product development from the ground up. 56% of companies have already incorporated AI into their product or service lineup, and those who do so are grabbing VC attention. Generative AI products received 5x more investment dollars than last year.

But, as more businesses bring AI-fueled products and features into their roadmaps, they’re facing a major hiccup: the AI talent crunch. The demand for AI and ML developers in the US is expected to skyrocket by 300% over the next two years. Natural Language Processing (NLP) and Large Language Models (LLM) skillsets are in especially high demand, with companies increasing their adoption of SaaS LLM APIs by 1310% since 2022.

Given this escalating demand and low rates of tech unemployment, companies face an uphill battle in securing the right tech talent to scale their products.

And, it’s not getting better anytime soon: The AI market is projected to hit $407 billion by 2027. Developing an effective hiring approach now is critical for building the team of tomorrow. 

In this guide to hiring AI & ML developers, you’ll find insights into the AI talent landscape, strategies for sourcing and interviewing devs, and best practices in managing and nurturing talent. We’ll help you hire an AI developer effectively and ensure long-term success.

Part One: Decoding the AI/ML developer profile 

Not all AI products, or AI developers, are created equally. The field is broad and the skills you need might vary based on what you’re building.

So, where do you start? Take a hard look at your product requirements. Then, you can match them with the appropriate recruitment objectives. This ensures you’re not just hiring talent, but the right talent. 

AI Developer Skills Cheat Sheet

If you’re building…

Here are a few of the essential soft skills for AI developers:

💬 Communication

Given the intricate nature of AI projects, developers need to communicate challenges clearly and coordinate effectively with multi-disciplinary  teams. This keeps everyone, from data scientists to product managers, aligned.

  • Interview questions to ask: 
    • Describe how you’ve communicated a complex AI challenge to a non-technical team.
    • Share a time when there was misalignment with another team. How did you resolve it?

🧐 Problem-solving mindset

The world of AI is ever-changing. Developers must venture into new areas without a set guide (there’s no guarantee you can Google trouble-shoot this one!). This makes a knack for problem-solving a must-have.

  • Interview questions to ask: 
    • Tell me about an AI challenge you faced without readily available online resources. How did you tackle it?

🚴 Patience and perseverance

Training an AI model is an ongoing process. Developers must be prepared for a cycle of testing, tweaking, and refining, requiring both patience and a drive to see projects through to the end. 

  • Interview questions to ask: 
    • Share an instance when an AI model you trained didn’t meet expectations. How did you respond?
    • Describe a situation where an AI project veered off course. How did you adapt and find a solution?

Structuring your AI development team

Developing AI systems requires a blend of specific skills and expertise. Carefully plot out your team’s structure as you hire AI & ML developers so that you can hire strategically for the product you’re building. While the exact makeup of teams may differ, there’s core functional areas you may consider building out: 

Data team

As custodians of the prized asset (data!), this team is often the backbone of an AI organization. Consisting of Data Scientists who uncover patterns, Data Engineers who architect and maintain pipelines, and Machine Learning Engineers who implement algorithms, this team keeps data flowing effectively and informs decision-making.

Algorithm team 

If data is the raw material, algorithms are the machinery that process it. This team, composed of Deep Learning and Machine Learning Engineers, designs, tests, and refines the algorithms that form the essence of AI systems.

Infrastructure/Platform team

This team protects the scalability, reliability, and efficiency of the tools and systems that AI applications rely on, from Backend Software Engineers who create the systems’ architecture to DevOps and MLOps engineers who streamline the development and deployment processes, and System Engineers who keep it all running smoothly.

Part Two: Sourcing and interviewing AI engineers 

Why you should look globally for AI/ML developers

The demand for engineering talent, especially candidates skilled in AI/ML, is growing by the day. It’s a highly specialized skill set, which means it may not be easy to hire the AI & ML developers you need in your backyard. That’s where global hiring comes in. 

Global markets are rich with talent and innovation. In Terminal’s State of Engineering Report, 75% of engineers living in these markets say they’re eager to be part of US tech enterprises. But, they don’t necessarily want to move to do so. Two-thirds say they want to stay fully remote.

Global teams bring a diversity of ideas, cultures and skills that can be an asset to your organization. What’s more, two-thirds of workers report feeling more productive when working remotely. And, you may also see some economic efficiency for your budget when hiring lower-cost, but high-quality talent outside expensive tech hubs.

Living in Austin, Texas, we’ve faced challenges like skyrocketing salaries and the race to secure talent. It was crucial for us to tap into global markets not just to find talent, but diverse talent. This is why we moved to global. My team is now 35% women, which is something I’m really proud of – it’s incredibly diverse and it’s the best team I’ve ever built.

5 steps to sourcing and interviewing AI/ML developers 

Securing the best AI talent must be done strategically – by taking time to build a strong hiring process (and iterating on it over time), you’ll be better set up to successfully hire AI & ML developers..

Define your ideal candidate

Begin with clarity. HR and Engineering should work together to clearly define the qualifications, experiences, and skill sets needed. Find example candidates online, and create a comprehensive candidate profile to guide your search. Consider also plotting out the long-term team structure, predicting your needs down the line to inform the hiring priorities (and leveling) needed today.

Craft an effective pitch

Cold outreach on LinkedIn or other channels can be effective, but it must be approached carefully.  It’s not a sales pitch, but an opportunity to introduce developers to your company and what you’re building. Consider including a few of these key elements in your message: 

  • Use a short, punchy subject line, something personalized or attention-getting. 
  • Articulate the technical opportunity – what is your company building or working towards in the AI/ML space that is exciting or cutting-edge?
  • Express the value the candidate would bring. It’s not just about the opportunity you’re giving them. ML/AI developers have spent considerable time and effort building their skills and it’s important to acknowledge their experience. This is also an opportunity to better personalize the message, which can increase InMail performance by 15% or more. 
  • Share success stories or milestones that showcase your company’s trajectory. This isn’t merely a call for applications – it’s a compelling invitation to join a journey.

Top keywords for sourcing AI & ML developers on LinkedIn:

Machine Learning
Large Language Models (LLMs)
Natural Language Processing (NLP)
Python Ecosystem

Cloud Computing

Streamline your interview machine 

In Terminal’s Engineering Report, a common theme has emerged year over year: Almost all engineers are frustrated with the interviewing process. They report too many rounds, long delays, and generic formats. In fact, they say it can even turn them away from accepting a job offer.

As you plan your panel and the stages of the process, consider how you might streamline the experience for the candidate. At the least, prioritize clarity and timeliness, and keep candidates informed at each stage. While more in-depth homework and exercises may be needed to validate skills, remember to balance these asks with respect for their candidates and their time.

Part Three: Nurturing and growing AI talent beyond the hire

So you’ve hired AI & ML developers that are the right for your team and they’ve accepted! Now your focus should turn to setting the new team members up for success, and ultimately, retaining them over time. 

Developers have an annual turnover rate of about 11.5% (and some sources going as high as 21%). They receive frequent recruiter outreach and may be less inclined to stick around when they’re not fulfilled or challenged by their role.  

How can you nurture, train and engage your developers to keep them motivated and happy? Here’s a few strategies that have proven impact: 

Strong developer onboarding

Organizations with supportive new developer onboarding create a positive experience for new engineers. To ensure a successful start, provide materials and equipment before their first day, schedule an immediate 1:1 with their manager, and set clear onboarding milestones for them to achieve.

Why developer onboarding matters 
72% of employees say one-on-one time with their direct manager is the most important part of any onboarding process. 

Ritesh Patel, Co-Founder + CEO, The Ticket Fairy, agrees: 

“We actually have flown some [new employees]  in for five days of onboarding with me in person – we’re looking for that really bought-in mission-driven team.”

Training programs

The ever-evolving landscape of AI demands continuous learning. Platforms like Coursera and Udemy offer courses tailored for various AI competencies, from beginner to expert. Beyond this, you might also consider providing a budget for conference or event attendance, hosting accomplished AI / ML speakers, or providing mentorships with more senior engineering staff. The skills needed for AI development is changing quickly, so continued investment and upskilling will be a necessity.

Growth paths

Confusion over how to progress within an organization is challenging for any employee. Provide clear leveling plans for your eng org and communicate them clearly to each team member. Build regular manager check-ins (in addition to annual reviews) to understand each developer’s goals and build a plan to achieve them. 

Five tips for running effective remote teams
When hiring global AI engineers, you may start to see some common challenges of distributed teams, such as poor communication, lack of visibility and loneliness or isolation. 
Consider these tips to keep teams streamlined, connected, and effective.

1. Drive accountability: Set clear goals and establish mechanisms for the team to stay on track. Use focused blocks of time to minimize distractions and enhance productivity.  

2. Keep processes simple: Regularly review and refine team approaches to avoid sticking to routines just for the sake of it. Ensure that processes serve the team effectively.

3. Document everything but quickly: Over-communication is key in remote. From code to company information, have documentation that’s accessible to all but quickly created. Overlong documentation processes can be draining, but critical documentation quickly created can accelerate teams dramatically.

4. Balance communication modes: Use a mix of synchronous and asynchronous communication. This allows for autonomy and efficiency without sacrificing the human connection essential for team cohesion. Incorporate great async tools like Slack, Jira, and GitHub.

5. Empower managers: Support and train managers to guide their teams effectively. This includes structured 1:1s, feedback mechanisms, and career pathing.
