Senior Full Stack Software Engineer

Senior Full Stack Software Engineer

Remote | UK or Europe

Salary: UK salary band listed applies to UK-based candidates. Compensation across Europe is benchmarked according to the country you live in.

I am working with a software company I know exceptionally well, having recruited more than 70% of their engineering team over the last few years.

They have been operating for over three years, have won several major contracts, and are now continuing their growth with another key hire in engineering. This is a fully remote opportunity open to candidates across the UK and Europe, with compensation aligned to the country you are based in. The team also gets together several times a year in different countries, with all costs covered.

This is an outstanding opportunity to join a business building sophisticated software that supports highly regulated processes central to medical progress and innovation. Their technology enables specialist users to plan, explore, build, validate, submit, and review complex clinical trial outputs more efficiently, more accurately, and with greater confidence.

The role

As a Senior Full Stack Software Engineer, you will join a world-class engineering team building a modern platform that exposes clinical trial insights to specialist users across technical, medical, and regulatory functions.

You will be working across a suite of core platform capabilities that support the planning, onboarding, build, validation, submission, and review of complex workflows and outputs. The platform sits at the intersection of software engineering, data workflows, visualisation, and AI-assisted automation.

Its data pipelines analyse clinical trial documentation, code, logs, datasets, and outputs to create deep traceability and logic lineage, helping transform complex trial processes into structured, usable information infrastructure. This enables experts to work more effectively while opening up powerful new opportunities for intelligent automation.

As part of the core team, you will build and test new functionality across the full stack, troubleshoot customer issues, drive root-cause resolution, and contribute to the continued improvement of performance, scalability, reliability, security, and engineering quality. You will also play an important role in helping align technical work across teams and maintaining high standards across delivery.

Tech environment

You will be working in an engineering environment built around:

• TypeScript, React, Next.js and Node.js
• A modern full stack setup where frontend capability matters, but deep frontend specialism is not essential
• The chance to work on user-facing product development while continuing to build on your React and frontend experience
• Cloud-native deployment with Docker and Kubernetes
• CI/CD and release workflows including GitHub Actions
• Supporting technologies across data processing, workflow orchestration, and AI-enabled tooling

It would be especially well suited to someone who enjoys deep technical problem-solving and is interested in areas such as compilers, parsers, graph algorithms, static analysis, dependency resolution, lineage, and complex data modelling.

What they are looking for

• Strong commercial experience as a full stack or backend-leaning engineer, with some exposure to React or modern frontend development
• Strong experience with TypeScript, Node.js, and modern JavaScript frameworks such as Next.js
• Experience building scalable client-server or full stack applications
• A solid grounding in HTML, CSS, responsive design, and general frontend principles, without needing to be a frontend expert
• Experience with testing, integration testing, and writing reliable production code
• Experience with CI/CD and modern engineering workflows
• Strong communication skills, a collaborative mindset, and a genuine interest in building further capability on the frontend side

Important note

You do not need to be a frontend expert, but you should have some exposure to modern frontend development and be keen to build on it.

This role would suit a strong full stack or backend-leaning engineer who has some frontend exposure and wants to continue developing in that area.

Nice to have

• Tailwind CSS or similar
• Graph theory or algorithm-heavy experience
• Application security knowledge
• Experience working in regulated, validation-led, or compliance-focused environments

Why join?

• Fully remote across the UK and Europe
• UK salary band applies for UK-based candidates, with European compensation benchmarked by location
• A company in strong growth mode after major commercial wins
• Genuinely interesting technical challenges with real-world impact
• Fully paid team meetups in different countries several times a year
