Job Description
Posted on: April 26, 2026
We're working with a pioneering life sciences innovator bridging the gap between cutting-edge AI and biological breakthroughs on this exciting opportunity. Join a high-impact team building the next generation of Agentic AI platforms to revolutionize how scientific data is visualized and processed. You will be at the forefront of integrating LangGraph and PydanticAI with robust Python backends and sleek React frontends to accelerate pharmaceutical discovery. The Role
- Lead the frontend implementation for high-performance React applications, focusing on complex visualizations of genomic and proteomic data.
- Architect and integrate AI/ML components and Agentic workflows (LangGraph, AutoGen) within a Google Cloud (GCP) and Cloud Run environment.
- Bridge the gap between design and engineering by converting Figma prototypes into interactive, data-rich web applications.
- Build and maintain end-to-end data pipelines in collaboration with Data Engineers to ensure seamless flow from raw scientific data to actionable insights.
- Ownership of the full SDLC, including writing automated test suites with Playwright and Cypress to ensure mission-critical stability.
What You'll Need
- Proven expertise in Fullstack development using TypeScript/React and Python (FastAPI) to build scalable, clean, and maintainable codebases.
- Deep experience with Google Cloud Platform (GCP), Cloud Run, and containerization using Docker for multi-container architectures.
- Hands-on experience with Agentic AI frameworks such as LangGraph, PydanticAI, or AutoGen is highly desirable.
- Solid background in high-level automated testing (Playwright, Cypress) and modern CI/CD workflows using Git/GitHub and DevOps tooling.
- A background or strong interest in Life Sciences (Genomics, Transcriptomics) or the Pharmaceutical industry is a significant advantage.
What's On Offer
- 12-month initial contract with a global leader in scientific innovation.
- Hybrid working model (2 days onsite in London) offering the perfect balance of collaboration and focus.
- Opportunity to work on "bleeding-edge" AI projects that have a real-world impact on human health.
- Collaborative environment working alongside world-class data scientists and researchers.
