Senior Front-End Software Engineer

About this role

We’re Cyted, a pioneering gastrointestinal diagnostics company transforming earlier detection for oesophageal cancer and Barrett’s oesophagus. Our EndoSign test combines a swallowable capsule with advanced biomarkers and analytics to detect disease earlier, improving patient outcomes while reducing pressures on healthcare systems.

What started as an idea between a health-tech entrepreneur and leading clinical scientists in Cambridge UK, has quickly grown internationally, backed by EQT Life Sciences and a $44M Series B investment.

But we still work like a startup - because we are one. Things move quickly and we’re building as we go. Some days you’ll solve brand new problems and others you’ll roll your sleeves up and get things done.

We’re a collaborative team, so your work matters. We have our investors trust, but you won’t disappear into layers of hierarchy, waiting months for decisions. If you've got a good idea, we want to hear it - whatever your role.

We like curious, adaptable people who are always willing to learn. This isn’t a polished corporate - we’re building as we go. If you're excited to help build something ambitious from the ground up that makes a real difference to patients' lives - we'd love to hear from you.

Our four-stage process runs on a rolling basis, with each stage serving a clear purpose. Shaped by candidate feedback, we've designed it to give you honest insights into Cyted, whatever the role.Initial conversation – A relaxed online conversation with Maddie from our People team to get to know you, talk through your experience and answer any questions you have about Cyted. Line manager interview – An online discussion exploring the role in more detail through scenario-based and role-specific questions. Team interview & assessment – Meet the wider team in person and see how we work. You'll complete a presentation or practical assessment so we can hear your ideas and see how you approach challenges at Cyted. Final Interview – Marcel, our CEO, still meets every potential new joiner. It's an opportunity to discuss your ambitions and how they align with Cyted's journey and future vision.

Our clinical platform is where clinicians, laboratory staff and pathologists interact with Cyted every day. You'll help evolve its front end, turning clinical workflows into intuitive, accessible experiences that make it easier for healthcare professionals to do their jobs.

Working alongside engineers, commercial and operational teams and clinical specialists, you'll help shape features from early ideas through to release, learning directly from the people who use the platform while balancing user needs with clean, scalable engineering. We value fresh thinking and engineers who enjoy finding smarter ways to build reusable components and continually improve the front-end architecture.

As Cyted expands into the US, you'll build on a platform that's already delivering real value in the UK. Using everything learned from our users, you'll help adapt and evolve the product for a new healthcare system, playing a meaningful role in the next stage of its growth in the US.

If you're someone who enjoys learning, asking questions and improving with every project, you'll find plenty of opportunities to stretch yourself here. You'll be trusted to contribute, supported to grow, and encouraged to make a real impact within both the product and the engineering. 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.
