Senior Front-End Software Engineer in Cambridge

About Us
We’re Cyted - a pioneering gastrointestinal health diagnostics company enabling more patients 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. But 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. If the idea of helping build something ambitious from the ground up excites you - and you want your work to have a real-world impact on people’s lives - we’d love to hear from you.

Our recruitment process runs through four stages and we interview on a rolling basis. Each stage has its own purpose. As we have grown, we have made each contact point based on candidate feedback, making sure you actually get a helpful insight into Cyted. We want to give you the most open & true snapshot of us no matter the role.

• Initial conversation – Run by Maddie from our People team, this is a relaxed online chat so we can learn more about you and your background, and so you can learn more about us too.
• Line manager interview – This online chat explores the role in more detail through scenario-based and role-specific questions to see how you would bring your skills and knowledge into Cyted.
• Team interview & assessment – To meet the wider team and see how we work in-person, we like to involve a panel of team members to listen to your ideas in either a presentation or assessment format.
• Final Interview – Marcel, our CEO, still speaks to every new potential employee. In this online meeting, you will get to discuss your goals and explore how they align with the company’s history and future vision.

Job Summary
Clinicians, laboratory staff, pathologists, and most of all, patients are at the heart of what you will do. Making sure they deliver and receive critical healthcare information is central to your role. You will translate complex clinical workflows into clear, accessible and scalable front-end solutions. Not just so healthcare professionals can retrieve the information they need, but can do so using a platform and interface that is seamless, effortless and intuitive. Branching out of the software engineering team, you will also leverage opportunities to work with product and clinical stakeholders internally at Cyted, and externally. With curiosity and passion, you will own and elevate discovery through to delivery whilst 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 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 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

• 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 get excited by taking 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.

Your first two weeks will be meeting and getting to know us, as well as the wider team members at Cyted. You will get some 1:1 time out at lunch with a buddy to form a friendly face and go-to for any questions. To immerse yourself in how we operate, you will do some compliance training related to our lab quality management system, and get right into our sprint meetings: stand ups, demos, retros and planning. Whilst understanding our objectives, priorities and software stack, in your first month you will get stuck in contributing to our team outcomes by delivering and testing code. From chats and meetings with wider team members, you will start to form a solid understanding of what they really need from our software. By the end of your first six months you will have led end-to-end a major piece of work like a FHIR API to integrate with patient record systems, new features for pathologists to request and receive second opinions or support development of a computational pipeline that operationalised our R&D team’s genetics test. You will also have helped with triaging and responding to support requests from colleagues around the business for a sprint and informed where our priorities are for the next quarter in a team day.

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. 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.
