Software Engineer; Lab Technology

Position: Staff Software Engineer (Lab Technology) #4907
London, UK Research & Development – Technology /Full-Time /Hybrid Our mission is to detect cancer early, when it can be cured. We are working to change the trajectory of cancer mortality and bring stakeholders together to adopt innovative, safe, and effective technologies that can transform cancer care.

We are a healthcare company, pioneering new technologies to advance early cancer detection. We have built a multi-disciplinary organization of scientists, engineers, and physicians and we are using the power of next-generation sequencing (NGS), population-scale clinical studies, and state-of-the-art computer science and data science to overcome one of medicine’s greatest challenges.

GRAIL is headquartered in the bay area of California, with locations in Washington, D.C., North Carolina, and the United Kingdom. It is supported by leading global investors and pharmaceutical, technology, and healthcare companies.

For more information, please visit grail.comThe Lab Software team builds and operates the core software systems that make these laboratories possible. We develop the software platform that orchestrates sample processing, provides real-time laboratory visibility, maintains complete sample traceability, and enables laboratory operators to confidently run complex workflows  systems sit at the intersection of software engineering, laboratory automation, and clinical operations. They must be highly reliable, fault tolerant, and compliant with GxP requirements while supporting continuous innovation and increasing laboratory throughput.

We're looking for a Senior or Staff Software Engineer to help shape the next generation of GRAIL's laboratory platform. Leveling will be determined based on experience and demonstrated impact.

You will normally be working a hybrid of remote and office based, with no less than 3 days in the office (Mon, Wed and an additional day in office); when you are working out of our London office, you will be based at 210 Euston Road, London, NW1 2DA
, in line with company needs.

Responsibilites What You Will Work On As a Staff Software Engineer, you'll design, build, and operate the software systems that power GRAIL's automated laboratories.

You'll work across services including laboratory workflow orchestration, LIMS, quality decision systems, and laboratory visibility tools that enable operators to safely process patient samples  challenges you'll solve extend well beyond traditional backend software development. You'll collaborate closely with laboratory operators, scientists, automation engineers, and software engineers to understand complex laboratory workflows and build systems that remain reliable under real-world operating conditions.

This work requires balancing reliability, scalability, regulatory compliance, and operational simplicity. You'll design software that recovers gracefully from failures, supports 24-hour laboratory operations, improves operator efficiency, and enables the laboratory to continue evolving as new assays and technologies are introduced.

You'll help build resilient distributed systems that interact with physical laboratory equipment, support software-only disaster recovery, and continuously improve the intelligence and efficiency of the laboratory platform.

Most importantly, every improvement you make helps GRAIL process patient samples more reliably, efficiently, and at greater scale.

You Are Someone Who...Simplifies complex systems

You enjoy breaking down complicated technical and operational problems into elegant, maintainable solutions. You understand that simplicity is often the key to building reliable systems.

Comfortable working across the full stack

You are happy to move between backend and frontend to solve a problem end to end.

Anticipates problems before they happen

You proactively identify technical and operational risks, designing systems that prevent failures instead of simply reacting to them.

Partners across disciplines

You enjoy working with scientists, laboratory operators, automation engineers, and fellow software engineers. You ask thoughtful questions, understand customer needs, and translate them into practical technical solutions.
