About the role

About the Role

Join the Engineering team at an AI/ML company building applications that help researchers and domain experts create, review, and analyze research data. You will develop user-facing interfaces and backend services that support core research workflows.

What You'll Do

  • Build interfaces for creating tasks, reviewing files and video, inspecting agent actions, and comparing experimental results.
  • Develop APIs and PostgreSQL data models for tasks, reviews, files, and experiments.
  • Connect applications to data pipelines and file storage with input validation, permission controls, and clear error handling.
  • Work with researchers and domain experts to improve workflows, investigate bugs, and maintain performance as datasets grow.

What We're Looking For

  • At least 3 years of experience building and maintaining applications used by others, with 5 to 10 or more years preferred.
  • Strong TypeScript and React skills, or Python experience with a backend framework such as FastAPI, and willingness to work across the stack.
  • Experience designing APIs and working with SQL and relational databases such as PostgreSQL.
  • A practical approach to testing, debugging, and incorporating user feedback, along with initiative and collaborative problem-solving.
  • Experience with annotation tools, research software, or large dataset exploration is valuable. Familiarity with AWS, S3, background jobs, or frontend testing tools is also useful.

Compensation & Benefits

Location

On-site in Zürich, Switzerland.
