What Does an AI Researcher Do?

At a glance, an AI researcher might sound like someone tucked away in a lab, buried in equations and academic papers. And while they do love a good algorithm, their role is far more dynamic and increasingly essential to business innovation.

So, what exactly does an AI researcher do? In short, they develop the next generation of artificial intelligence models and systems. Unlike AI engineers who focus on implementing existing tools, AI researchers create entirely new ones. They explore uncharted territory in machine learning, deep learning, natural language processing (NLP), computer vision, and other subfields of AI to solve problems that don’t yet have solutions.

From designing new neural network architectures to publishing peer-reviewed studies, their job is equal parts theory, experimentation, and application. Their insights often lead to breakthroughs that power everything from personalized customer experiences to automated decision-making systems and intelligent automation.

For businesses, this means they’re not just employees; they’re innovation engines. AI researchers can give your company a competitive edge by:

  • Developing proprietary AI tools that can’t be found on the open market
  • Optimizing existing machine learning models for better performance
  • Identifying new ways to use AI for efficiency, personalization, or prediction
  • Collaborating with engineers, data scientists, and product teams to bridge the gap between research and real-world results

In short, if your business is aiming for custom solutions, patentable ideas, or high-impact AI systems, this is the role that takes you from using AI… to inventing it.

When Should You Hire an AI Researcher?

Not every company needs an AI researcher, but the ones that do? They’re usually the ones building the future.

So how do you know if your business is ready to bring one on board? It all comes down to your goals. If you’re simply looking to integrate existing AI tools, like chatbots, recommendation engines, or automation platforms, a skilled AI engineer or data scientist might be all you need. But if you’re pushing the envelope with custom models, proprietary algorithms, or complex machine learning challenges, it’s time to think bigger.

You should consider hiring an AI researcher when:

  • You’re developing a new AI-powered product or feature that goes beyond pre-built APIs
  • Your company wants to own its intellectual property (IP) in AI or pursue patents
  • You’re building your own machine learning models from scratch rather than relying on off-the-shelf solutions
  • You’re entering a competitive space where speed, accuracy, or personalization can offer a major edge
  • You want to experiment with cutting-edge technologies like generative AI, reinforcement learning, or multimodal models

Industries that benefit most from in-house AI research include:

  • Healthcare (medical imaging, diagnostics, drug discovery)
  • Finance (fraud detection, algorithmic trading, credit scoring)
  • Retail and E-commerce (personalization engines, demand forecasting)
  • Autonomous systems (robotics, self-driving vehicles, drones)
  • SaaS & Enterprise Tech (process automation, NLP, predictive analytics)

If you're a startup, hiring an AI researcher early can establish your product’s technical moat; that layer of defensible innovation competitors can’t easily replicate. For larger enterprises, an AI research team can future-proof your strategy and reduce long-term dependency on third-party tools.

And here’s the best part: you don’t need to pay Silicon Valley prices to access this level of talent. Many companies are turning to Latin America for AI researchers, where PhD-level professionals work in similar time zones, speak fluent English, and bring cutting-edge expertise at a fraction of the U.S. cost.

  • Check for peer-reviewed publications in respected venues (NeurIPS, ICML, CVPR, ACL, etc.).
  • Look for relevance: Does their past work align with your business challenges?
Assign a Research-Focused Task
  • Instead of a coding test, give them a real-world problem statement: e.g., “Design a high-level approach for identifying anomalies in transaction data.”
  • Look for their ability to formulate hypotheses, structure experiments, and choose the right models, even if it’s a whiteboard exercise.
Evaluate Theoretical Depth

Ask questions that test their understanding of machine learning fundamentals, like:

  • What’s the difference between overfitting and underfitting?
  • How do you select the right loss function for a specific task?
  • What tradeoffs would you consider between model accuracy and interpretability?
Assess Collaboration & Communication
  • Can they explain complex research ideas in plain English?
  • Are they comfortable discussing their work with cross-functional teams (engineering, product, leadership)?
  • Strong communication is key, especially when hiring remotely or nearshore.
Validate Fit for Remote or Nearshore Work

If hiring from Latin America or another region, test for:

  • English fluency (written and spoken)
