Company mission
To deliver the most seamless experience for data pipelines at scale, with a focus on the life sciences.
Role
Who you are
- Ideal candidates have strong backend experience, familiarity with cloud-native architectures (AWS/GCP), and are excited about applying AI to meaningful problems
- Bonus if you’ve worked with developer tools, scientific data, or deployed software in customer environments
- You’re a strong software engineer with experience across both backend and frontend systems
- You’ve built, shipped, and maintained real-world applications — ideally with exposure to data, ML, or research tooling
- You have production experience with at least one major cloud provider (AWS, GCP, Azure) and have built distributed systems or services using cloud-native patterns
- You’re comfortable with container technologies (Docker) and preferably orchestration tools like Kubernetes or Docker Compose
- You write well-tested, secure, and performant code and know how to balance speed with quality
- You’re independent, communicative, and thrive in fast-moving, collaborative teams
- You’re excited about AI and curious about scientific applications — and you want to work on real tools that help real scientists
Desirable
- Experience with LangChain, LangGraph, or other LLM frameworks
- Experience building developer tools or internal platforms
- Exposure to biotech, scientific data, or research/ML pipelines
- Frontend experience with React, Astro, or similar frameworks
- Familiarity with building tools deployed in customer-controlled environments (e.g., on-premise or hybrid deployments)
What the job involves
- We’re looking for a senior software engineer to join our AI/Growth team and help us design and build AI-powered workflows, backend services, and user-facing tools that accelerate scientific discovery
- You’ll work with modern LLM frameworks, build robust APIs and services, and contribute to a team that balances experimentation with rock-solid engineering
- In this role, you’ll work across our stack — building AI-driven workflows, scalable backend services (Python), and user-facing tools (React). You’ll take ideas from concept to production, collaborating with a small, fast-moving team focused on delivering real value to real scientists
- Design and implement large language model (LLM)-driven workflows
- Build and maintain backend systems and APIs using Python and FastAPI
- Collaborate with frontend engineers on user-facing tools (React, Astro) that scientists love to use
- Own end-to-end services from development to deployment using cloud-native and containerized environments
- Improve our AI/Growth team’s engineering practices around testing, observability, automation, and release processes
- Partner closely with product, UX, and domain experts to understand how scientists use our tools — and how we can make them better
Our take
Commercial DNA sequencing and advances in biometrics have led to an explosion in biological data, which is likely to prove critical in tackling the major problems facing the life sciences. The problem is, the data is so vast in quantity and diverse in type that analysing it and managing it can prove prohibitively expensive. This is where data orchestration and workflow platform Seqera Labs comes into its own.
Seqera is focused predominantly on facilitating big data analysis and management in the life sciences, and it has gotten impressive traction. Its Nextflow product, a distributed data analysis solution, has been used by over 10,000 organizations. This has included teams working on COVID sequencing, and on cancers.
What's so valuable about its offering is that it can be used by people who understand the data without the need for external teams, which has led to it becoming an industry standard. Seqera has been funded generously, and acquired AI bioinformatics company TinyBio, empowering it to play a pivotal role in key life-sciences developments going forward.
