Senior Front-End Engineer for Healthcare Diagnostics in Cambridge

We’re Cyted – a pioneering gastrointestinal health diagnostics company enabling early access and detection for esophageal cancer and Barrett’s esophagus. Our technology brings a minimally invasive diagnostic approach to market – our EndoSign test combines a swallowable pill‑like device with advanced biomarkers and analytics to help detect disease earlier and faster.

What started as an idea between a health‑tech entrepreneur and leading clinical scientists at Cambridge University has quickly grown into an international company operating across the UK and US, backed by investors such as EQT Life Sciences and a $44M Series B investment. We still work like a startup – because we are one. Things move quickly here and we build as we go. Some days you’ll be solving problems first of their kind with innovative approaches. Other days you’ll just need to roll your sleeves up and get things done. That’s the reality of building a company that’s growing fast and trying to genuinely change patient outcomes.

We’re a small, highly collaborative team, which means your work matters. We have the trust and belief from our investors so you won’t disappear into layers of hierarchy or spend months waiting for decisions. If you have a good idea, we want to hear it, regardless of your role or title. We like people who are curious, adaptable, thoughtful, and always willing to learn and improve. This isn’t a polished corporate environment where everything already exists. We’re building processes, teams, products and ways of working in real time. Every day is different.

Job Summary

Clinicians, laboratory staff, pathologists, and most of all, patients are at the heart of what you will do. Making sure they receive critical healthcare information is central to your role. You will translate complex clinical workflows into clear, accessible, and scalable front‑end solutions so healthcare professionals can retrieve the information they need using a seamless, effortless, and intuitive platform.

Branching out of the software engineering team, you will also leverage opportunities to work with product and clinical stakeholders internally and externally. With curiosity and passion, you will own and elevate discovery through to delivery while engaging directly with users to ground solutions in real‑world challenges.

We love inventive and innovative perspectives to bring fresh approaches that lead the way we build robust and reusable components to strengthen the front‑end architecture. Boldly raising our engineering standards across the team and internationally into the US is exactly what we want. You will immerse yourself in challenging assumptions, driving practical solutions and reliably step up to shape how our team delivers high‑quality outcomes to clinicians, laboratory staff, pathologists, and patients.

Working Pattern and Location

This role is a full‑time position with a standard 37.5‑hour working week. You will be based at 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

• User Insight and Collaboration: Constantly engage directly with pathologists, clinicians, and internal service teams to understand real‑world workflows and pain points. Demo work regularly, inviting challenge and feedback, and iterating based on insight.
• Front End Development: Design and build intuitive, accessible UI for laboratory staff, pathologists and clinicians. Translate complex clinical workflows into simple, effective digital experiences. Partner with backend engineers and international stakeholders to deliver a seamless end‑to‑end product. Build robust, scalable and reusable front‑end components and patterns. Raise issues early, propose practical solutions and take ownership through delivery.
• Product and Platform Delivery: Inform, design and deliver diagnostics platform capabilities aligned to business priorities and customer value. Build reusable code and shared libraries that strengthen long‑term architecture. Successfully integrate third‑party services to extend platform capability. Drive forward new technologies and approaches that improve productivity and quality.
• Engineering Excellence: Proactively diagnose and resolve challenges quickly and methodically. Define test plans, write automated tests and conduct manual testing when needed. Support security reviews, audits and penetration testing and implement recommendations.
• Ways of Working: Mentor and support the team’s engineers to raise standards and international impacts. Consistently share expertise and promote best practice within the team. Contribute to Agile delivery and continuous improvement. Collaborate to plan, prioritise and deliver work with clarity and discipline.

Onboarding and Early Impact

Your first two weeks will be spent meeting and getting to know the wider team, including one‑to‑one time out at lunch with a buddy, compliance training related to our lab quality management system, and sprint meetings (stand‑ups, demos, retrospectives and planning). During the first month you will contribute to our team outcomes by delivering and testing code, gaining a solid understanding of what the team needs from our software. By the end of your first six months you will have led a major end‑to‑end project such as a FHIR API to integrate with patient record systems, new features for pathologists to request and receive second opinions, or support the development of a computational pipeline that operationalises our R&D team’s genetics test. You will also have helped triage and respond to support requests from colleagues around the business for a sprint and informed where our priorities are for the next quarter.

Who you are?

We’re looking for a senior software engineer with the technical depth and practical experience to build high‑quality systems in a fast‑moving, mission‑driven environment. You’ll bring strong engineering fundamentals, confidence working across modern tooling and the ability to take ownership of meaningful technical outcomes.

To Succeed In This Role, You’ll Bring:

• A minimum of four years experience in a software engineering role
• Practical experience working with modern CI/CD tools
• Experience with AWS and Terraform
• Ability to build RESTful APIs in JVM languages such as Scala or Kotlin
• Approaches building web frontends using React and TypeScript
• Experience conducting or contributing to user research
• Excellent problem‑solving ability, analytical thinking and strong troubleshooting skills
• Ability to mentor junior team members (no line management required)

How we work

At Cyted, how we work is just as important as the impact we create. Following our recent Series B fund raise and with increasing national attention, we’re entering a defining stage of growth and our values guide how we scale. 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, understanding users’ pressures and designing technology that reduces friction. You’ll bring empathy and clarity into your engineering decisions, anchoring 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, understand the science, data flows, workflow logic and constraints of real‑world clinical settings. You’ll anticipate edge cases and solve problems rather than passing them along. Everything runs in the same spirit – comfortable with specifics of a diagnostic workflow as with 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. 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 bottlenecks and push the platform forward, bringing 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.
