  • Optional Opportunities: Optional opportunities exist to explore LLM word token bounding box detection, LLM as a Judge, and other LLM evaluation work.
  • Collaborate on Cloud Deployment: Partner closely with ML Ops and Data Science Engineers to seamlessly deploy datasets, truth sets, models, and pipelines for training and inference in cloud environments.
  • Communicate Insights Effectively: Clearly and confidently present your findings, deliverables, and proposed solutions to technical and non-technical audiences, including teams, stakeholders, and executives.

Requirements:

  • 5+ years of experience in Data Science with AI/ML
  • Proven experience in Python programming as well as tools and environments for model deployment.
  • Knowledge and experience with multiple AI LLMs, including both proprietary and open-source models, and their respective strengths and limitations.
  • Knowledge and experience with such frameworks as VLLM, SGLang
  • Ability to stay up-to-date with new models, benchmarks, and best practices.

  • Collaboration & Impact: Work alongside top industry professionals and help shape the tools that bring family history to life for millions of users.
  • Innovation & Purpose: Join a team at the forefront of applying AI to historical data where every model you build helps preserve human stories.

What do we offer our new colleague?

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
