Senior Full Stack Engineer

We are looking for a Senior Full Stack Engineer to join our founding team and take ownership of both product and infrastructure development. This role is for you if you are looking for a broad, hands-on engineering role, moving between user-facing product work, backend API design, cloud infrastructure and deployment pipelines.

You will work close to the core product: building interfaces scientists use every day, designing the systems that run agentic workflows, and hardening the platform as it moves from pilots into production customer environments.

What you’ll do

• Build product features across React, Next.js, and TypeScript.
• Design, build, and maintain backend Python backend services and APIs; build and maintain infrastructure using Terraform, Docker and Kubernetes, on GCP.
• Improve the reliability, scalability, and maintainability of production systems.
• Listen to user feedback, identify product opportunities, design practical solutions, test them with users, and ship improvements quickly.
• Work both independently and as part of a team on multiple projects in parallel and delivering them on a tight schedule using any tool you may see fit, including AI-assisted coding
• Work with scientists, customers, and the wider team to turn real-world workflows into robust product capabilities.
• Help shape engineering practices in a small, fast-moving technical team.
• Make pragmatic technical decisions across the full stack, balancing product speed with long-term system quality., * High ownership: you notice what needs doing and carry it through.
• Product-minded: you care about whether scientists can actually use what you build.
• Systems-minded: you can reason across frontend, backend, database, infrastructure, and deployment boundaries.
• Pragmatic: you choose simple, robust solutions and avoid unnecessary abstraction.
• Reliable under ambiguity: you can make progress when requirements are incomplete.
• Security-conscious: you understand the importance of permissions, auditability, and data boundaries.
• Clear communicator: you can explain technical decisions to engineers, scientists, and founders.
• Curious about science: you do not need to be a biology expert, but you should want to learn the domain.

• Experience working at an early-stage startup (as founder or early-employee)
• 5+ years of full stack engineering experience with Python backend/API development, modern React, Next.js, TypeScript, and backend REST APIs.
• PostgreSQL experience, including schema design, migrations, indexing, and data modelling; managing cloud infrastructure with Terraform; running production workloads on GCP and Kubernetes.
• Strong CI/CD and Git workflow experience.
• Experience owning software products end to end, from design and implementation through deployment, monitoring, and debugging.
• Experience supporting and maintaining production services, including complex system migrations with minimal downtime.
• Comfort working in ambiguous, fast-moving environments where product and technical requirements evolve quickly., * Experience in life sciences, biomedical research, bioinformatics or scientific computing workflows.
• Experience building agentic AI systems, and sandboxed execution environments for LLM-based workflows.
• Experience with security, access control, RLS, authorisation, or compliance-conscious product development.

• Competitive salary and share options in the early stage of a fast-growing startup
• Private health insurance
• Regular team events and lunches
• Fast-moving startup environment with a passionate team who enjoy solving problems
