How to Hire Top Artificial Intelligence Engineers

Artificial intelligence is becoming an increasingly integral part of various industries, especially those driven by data—think finance, healthcare, retail, and more.

And those industries need skilled AI engineers who can create cutting-edge AI applications, train machine learning models, and maintain the integrity of an AI tech stack.

If your company is struggling to implement or improve an AI system, an AI engineer can help—here's how to build a great talent pool.

Write a job post to hire freelance AI engineers

The AI development engineer hiring process begins with crafting a great job post. Luckily, this isn't hard—it's just a matter of knowing what AI capabilities you're looking for and then explaining requirements in a concise manner.

Job post title

The hiring process starts with the job post title. The title should be clear and to the point, with a focus on the industry speciality or unique skills that you want the engineer to have.

Take a look at these AI engineer job post titles on Upwork for inspiration:

"AI engineer needed for intelligent document processing"
"Hiring chief AI engineer for AI autonomy software company"
"Seeking AI engineer specialized in RAG and prompt engineering"
"AI engineer / model trainer for LoRa and Stable Diffusion"
"AI engineer needed for large language model (LLM) development"
"Hiring AI engineer—Graph RAG and LLM models specialist"
"Startup needs advanced AI engineer for luxury fashion menswear brand"

Project description

Next, you'll need to expand upon your title by writing a comprehensive description. You don't need to go into every single detail about the job, but focus on the most important points:

Scope of work. Scope encompasses all stages and deliverables in a freelance project. It's important to be clear about what you need from an AI engineer so that you attract professionals who are able to deliver the work. For example, scope could involve training an LLM and handing it off to your internal team—or consulting internally, training the AI, and providing ongoing support for continued training and tweaks.
Project timeline. Timeline goes hand-in-hand with scope. If you need your AI engineer to complete specific deliverables in a given time frame, note that here. Similarly, make sure to mention any key dates, like when you want to kick off the project.
Background. Providing some top-level background about your industry and your goals for the project can help ensure you find professionals who are aligned with your vision and approach.
Budget. It's also important to include your budget in a freelance AI engineer job post. It's okay if this is a range, and you can choose to structure your budget as a flat project rate or a per-hour amount.

Project requirements and responsibilities

Your job post should also include details around the AI engineer's intended responsibilities. This may be part of your scope-of-work statement or its own section of the job post.

Responsibilities could include:

Selecting the right AI technologies
Working with data scientists to build training data sets
Training AI models and refining algorithms
Testing and validating AI models
Consulting with internal stakeholders on project progress and AI use
Cross-functional work with other members of software development, robotics, data engineering, and project management teams

AI engineer skills and qualifications

Finally, you'll want to list any required qualifications for your new AI engineer. This could include a specific educational level, number of years of experience, familiarity with certain machine learning algorithms, and a specialization in any of the following:

Programming languages like Python. Python is essential for AI engineers due to its extensive libraries and frameworks, making it ideal for developing and deploying AI models efficiently.

Computer vision. AI engineers use computer vision to enable machines to interpret and make decisions based on visual data, crucial for applications like image recognition and autonomous vehicles.

Deep learning. Deep learning allows AI engineers to create neural networks that can learn and make decisions, driving advancements in areas like speech recognition, natural language processing, and robotics.

Natural language processing (NLP). NLP enables AI engineers to design systems that understand, interpret, and generate human language, which is vital for chatbots, translation tools, and sentiment analysis.

Sentiment analysis. AI engineers use sentiment analysis to assess and understand the emotional tone behind textual data, which is valuable in fields like customer feedback analysis and social media monitoring.

Automation. Automation is key for AI engineers to streamline processes and enhance efficiency by developing AI systems that can perform repetitive tasks without human intervention.

Data analysis and visualization. AI engineers rely on data analysis and visualization to interpret complex datasets, identify patterns, and inform the development of more accurate AI models.

Generative AI algorithms. Generative AI algorithms allow AI engineers to create models that can generate new content, such as images, text, or music, by learning from existing data.

Speech recognition technologies. AI engineers develop speech recognition technologies to enable machines to understand and respond to spoken language, which is essential for virtual assistants and voice-controlled devices.

PyTorch, TensorFlow, and related frameworks. These frameworks are critical tools for AI engineers, providing the infrastructure needed to build, train, and deploy machine learning models efficiently.

AWS. AI engineers often use AWS for scalable cloud computing resources, which support the training, deployment, and management of AI models in a flexible and cost-effective manner.

You can also specify that you’re seeking an engineer with experience working on AI projects in your industry, if that’s important to you.

Understanding the role of an AI engineer

Finding and working with an AI engineer is easier once you understand what these professionals do—and why they're in high demand!

What does an AI engineer do?

An AI engineer may have a variety of responsibilities, all centered around the development and improvement of AI models. Their work can include:

Creation of machine learning models and neural networks
Initiation of supervised and unsupervised training methods
Implementation of trained machine learning models into existing systems
Validation of AI model training
Collection and curation of training data
Consultation with clients in need of AI solutions

What industries hire AI developers and engineers?

These professionals are essential team members on AI-powered projects in industries like:

Healthcare. AI engineers can build and train AI models to help analyze medical data and improve the speed of critical diagnoses.
Finance. AI engineers help finance companies by training models to detect fraud and assess risk potential.
Retail. Brick-and-mortar and online retailers can work with AI engineers to train algorithms that deliver personalized experiences to shoppers and provide real-time support via helpful chatbots.
Manufacturing. AI engineers may work with manufacturers to identify patterns in equipment breakdowns or improve quality control processes based on data.
Public utilities. Water, power, and gas companies may bring in an AI engineer to help them analyze grid usage and identify opportunities to reduce costs.
Transportation. AI engineers can build AI models that help transportation companies plan efficient routes and better manage fleets based on historical data.
