  • Collaborating closely with frontend engineers, data engineers, and ML specialists to build end-to-end pipelines.
  • Participating in agile ceremonies and code reviews to uphold quality and delivery standards.

Tech Stack & Skills

Core skills:

  • Strong Python backend development experience (FastAPI or similar frameworks)
  • Cloud-native deployment experience (preferably Google Cloud and Cloud Run)
  • Unit testing experience (pytest or similar frameworks)
  • Familiarity with agile development and CI/CD processes
  • Strong understanding of Git/GitHub workflows and DevOps tooling

Nice to have:

  • Experience with Docker or multi-container application architecture
  • Familiarity with AI/ML technologies such as LLMs, NLP, LangGraph, PydanticAI, or AutoGen
  • Experience with biological or scientific datasets (genomics, proteomics, etc.)
  • Exposure to frontend development (React preferred)
  • Experience benchmarking and improving AI/ML models or agent-based systems

What You'll Bring

  • A track record of delivering clean, production-grade backend systems
  • A collaborative and proactive approach to working in cross-functional teams
  • Passion for innovation and applying technology to advance scientific discovery
  • A growth mindset with a focus on continuous learning and improvement
