Your profile
Who We’re Looking For 
We’re looking for someone who thrives at the intersection of business, analytics, and AI: someone who not only trains models but also deeply understands the business context in which they’re applied. Your job is to make sure AI is solving the right problems, using the right approaches, and driving measurable impact.
  • Technical stack: You are comfortable writing and debugging in Python and SQL. You have hands-on experience training or fine-tuning ML models (classic ML or LLMs), and you know how to select the right method for a given business problem.
  • Business & product sense: You understand that AI is only valuable if it moves business metrics. You are skilled at identifying high-impact problems, choosing the right models and approaches, and validating your work with users and stakeholders. You prioritize by impact vs. effort and measure success using both model performance and business KPIs.
  • Scientist & builder: Curious and persistent, you try multiple approaches, analyze results, and iterate fast. You know when to experiment with cutting-edge techniques and when to pick simple, reliable solutions that can scale. You can break complex problems into shippable, value-adding steps.
  • Communication & influence: You explain complex results clearly to internal & external stakeholders, adapt your message to different audiences, and work cross-functionally with product, engineering, and business teams. 
  • Startup mindset: You are comfortable with ambiguity and open-ended problems. You are autonomous and proactive: when you see something broken, you fix it or propose improvements.
  • Bonus points: PhD in a technical field, strong knowledge of software engineering best practices, familiarity with state-of-the-art LLMs/agentic systems, deep expertise in a technical (time series, optimization, recommendations, causal inference…) or business topic (finance, manufacturing, supply chain, pharma...).
