Company Description
We are an early-stage consumer health-tech startup operating in stealth, building for the millions of people with chronic conditions who end up managing their health largely alone once standard care plateaus. We look at health as a system from the consumer side, and we are building toward better day-to-day outcomes in chronic disease, with what we learn feeding into research and policy.
We are funded by a secured, non-dilutive UK innovation grant, won on an extensive evidence base: a 600+ waitlist, a national partnership, and a mapped regulatory position. The product is co-designed with a live cohort of real users from the first months. The team is small and technical, you would work directly with the founder and our ML Lead, with real influence on technical decisions and product direction. We value low-ego, adaptability, curiosity and intellectual honesty.
Role Description
This is a full-time role for a Full-Stack Developer on a 4-month fixed-term contract, based in the UK, starting as soon as possible and tied to the funded project.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Design, build, and ship the user-facing product end to end: a React or Next.js front end, a Node or Python back end, and Postgres underneath.
- Day to day, build responsive interfaces, develop APIs, design and integrate the database, and handle sensitive personal data securely and in line with UK data-protection requirements.
- Participate in code reviews, contribute to architecture decisions, write clean testable code, troubleshoot, and iterate quickly with feedback from a live user cohort.
- Hand over a documented, runnable stack at the end of the contract.
- There is scope to extend and grow the role if our funding round closes during the window or if you wish to stay on for equity.
Qualifications
- Strong full-stack development skills, with experience delivering production-quality web applications end to end.
- Front-end development with modern JavaScript frameworks (we use React or Next.js) and CSS for responsive, accessible interfaces.
- Back-end development: server-side work in Node or Python, API design, and relational database integration (we use Postgres).
- Familiarity with secure coding and handling sensitive data; healthcare or another regulated setting is a plus, not a requirement.
- Comfort with modern AI-assisted development, and the ability to debug what the tools write.
- Ownership and self-direction in a fast-paced early-stage startup, collaborating closely in a very small team.
- Cloud platforms, CI/CD, and automated testing experience are beneficial.
- A degree in a technical subject is welcome but not required. We care about whether you can do this work, not how long you have been doing it: personal projects, coursework, and self-taught depth all count.
