Node.js / TypeScript Developer (Backend-Focused)
💰 £60,000 - £90,000 | 🏠Hybrid (4 days remote) | 📍 London
We’re supporting a purpose-driven tech company operating at the intersection of data, software, and healthcare, a business using technology to drive better health outcomes on a global scale.
They’re now looking for a Node Developer (Backend) who’s excited by the opportunity to build scalable, high-performing systems that make a tangible difference.
You’ll play a key role in shaping the technology that powers their modular platform — working closely with cross-functional teams to deliver new features, improve existing systems, and accelerate the product roadmap. This is a team that values ownership, creativity, and pragmatic problem-solving (sometimes the best solution isn’t starting from scratch).
The Opportunity:
In this role, you’ll be building and optimising backend systems and APIs that underpin the platform, working closely with cross-functional teams to deliver secure, scalable, and high-quality software.
You’ll have the freedom to take ownership of your projects, challenge how things are done, and use modern AI-driven tools to accelerate delivery and boost performance.
It’s a great fit for someone who enjoys autonomy, thrives in collaborative teams, and understands that building smarter doesn’t always mean building from scratch.
What You’ll Bring:
* Solid commercial experience with Node.js and TypeScript
* Strong understanding of API development (REST)
* Background working with SQL and NoSQL databases
* At least 3 years’ experience in backend software engineering
* Previous experience within healthcare (FHIR, HL7, EHRs, or LIMS) or exposure to Software as a Medical Device (SaMD) is highly desirable
* A proactive mindset and ability to adapt within a fast-moving environment
