Job Summary

As a senior software engineer at Cyted you will take the lead in building and evolving the systems that power medical insights and drive diagnostic workflows end to end. You will own meaningful technical outcomes, shape how our platform grows and set the standard for engineering quality across the team. You will work across a modern stack built on containerized Kotlin backends running in AWS and managed with Terraform. You will ship clean, reliable React interfaces in Typescript. You will also work on the integrations that make our platform effective in the real world, from internal links to digital pathology systems and genomic processing pipelines to external connections that deliver reports to customers and clinical trial partners. You will balance time, value and user needs with clarity and pragmatism. You will stay ahead of emerging technologies and engineering practices. You will mentor, guide and train other engineers to raise the bar. Above all, you will take full ownership of what you build and push it to deliver clear, tangible impact.

Working Pattern and Location

This role is a full-time position with a standard 37.5 hour working week. You will be based at the Cyted’s Head Office, Ground Floor, Building 3, Old Swiss, 149 Cherry Hinton Road, Cambridge, CB1 7BX, UK and be expected to be in the office 3 days per week.

What you will be doing

• Design and deliver new platform capabilities aligned to business priorities and real customer value.
• Build reusable code and libraries that strengthen long-term development.
• Maintain and upgrade existing software to keep it robust, scalable and reliable.
• Integrate the platform with third party services to extend its functionality and impact.
• Recommend technologies and engineering approaches that improve productivity and quality.

Engineering Excellence

• Analyse and troubleshoot issues with speed and accuracy.
• Create test plans, write automated tests and perform manual testing when required.
• Support technical audits and external testing such as penetration tests and implement recommendations.
• Mentor and guide other engineers to raise the standard of the whole team.

Ways of Working

• Shape and contribute to Agile and Continuous Improvement practices.
• Work with engineers to plan, prioritise and deliver features with clarity and discipline.
• Participate in team sessions to explore user needs, discuss priorities and contribute strong ideas.

User Insight and Collaboration

• Gather insight directly from users including pathologists, clinicians, IT teams and Cyted service teams.
• Demonstrate your work regularly and invite feedback from across the organisation to drive improvement.

What to expect

In your first two weeks you will meet the team and your buddy (a colleague from a different team who will be there to answer any questions you have - and take you out for lunch). You will also have training to do relating to our lab quality management system (QMS). You’ll attend all our sprint meetings (stand ups, demos, retros, planning) and start to get a feel for our objectives, priorities and software stack. In your first month you will contribute to team outcomes by delivering and testing code. You will also have met colleagues from around the business and have gained a good understanding of what they need from our software. By the end of your first six months you will have led a major piece of work, recent examples include an FHIR API to integrate with patient record systems in Wales, new features to enable pathologists to request and receive second opinions in our software, development of a computational pipeline that operationalised a genetics test developed by our R&D team. You will also have taken your turn triaging and responding to support requests from colleagues around the business for one sprint. You will have taken part in a Team Day and contributed to deciding priority outcomes for the next quarter.

How we work

At Cyted, how we work is just as important as what we build. Our values shape how we grow, collaborate and deliver for patients, clinicians and partners. As a senior software engineer, you’ll bring those values to life in the way you design, build and ship technology that matters. We care deeply about the patients we serve and the clinicians who rely on our diagnostics. For you, care means building systems that are reliable, intuitive and resilient. It means understanding the pressures on our users and designing technology that reduces friction rather than adding to it. You’ll bring empathy and clarity into your engineering decisions, always anchoring your work in the reality of clinical environments. We expect you to own your work with confidence and credibility. You’ll take responsibility for the systems you build, the decisions you make and the outcomes they drive. You’ll move with purpose, lead technically when needed and set high standards for the team around you. We aim high. We’re scaling fast and building in a complex, regulated space, but we’re not here to follow. You’ll help define what great engineering looks like in a new category of diagnostics. You’ll set ambitious technical goals, shape our architecture and deliver systems that clinicians can trust at scale. You’ll be expected to dive deep. You’ll understand the science, the data flows, the workflow logic and the constraints of real-world clinical settings. You’ll learn the detail behind our technology, anticipate edge cases and solve problems rather than passing them along. You’ll be as comfortable getting into the specifics of a diagnostic workflow as debugging a distributed system. We encourage everyone to challenge and commit. You’ll play a part in shaping how our engineering team works, what we prioritise and how we grow. You’ll question assumptions, propose better approaches and be open to critique. And once we choose a direction, you’ll go all-in and drive it forward with clarity and conviction. And above all, we deliver. This role demands momentum, ownership and results. You’ll write the code, shape the architecture, resolve the bottlenecks and push the platform forward. Every service you ship, integration you refine and problem you resolve brings us closer to earlier, better care for patients. This is how we work at Cyted. If this is the environment where you do your best engineering, we should talk.
