Job Overview iTakeControl is a clinical trial platform supporting live studies within a validated, GxP-compliant environment. We are bringing the platform fully in-house and building the team that will own and grow it.

We are looking for a strong Frontend Developer to own and advance the platform’s web interfaces as a hands-on, code-first contributor. The platform spans several substantial frontends — an operator-facing administration portal, a participant-facing web experience, and a registration experience — built on a modern React stack with a shared component library. Working under the technical direction of the Technical Lead, you will write production-quality frontend code, maintain a high bar for usability and accessibility, and help keep a live regulated platform stable, performant, and reliable.

The role begins by building a deep working understanding of the existing interfaces during the handover from the outgoing vendor, then moves into ongoing feature development, refactoring, and UI quality work within the established compliance framework. It is a delivery-focused role for an experienced frontend engineer who takes ownership of their work and cares about the details — performance, accessibility, and visual consistency — on a platform where clarity and correctness carry regulatory weight.

The nature of this role: this is a frontend software-engineering position. The day-to-day work is designing and maintaining large, stateful single-page applications — application architecture, complex client-side state, data-heavy interactive interfaces, performance tuning, and automated testing. It goes well beyond HTML/CSS markup, templating, or responsive styling: we are looking for someone who reasons about and structures frontend application code, not only its presentation layer.

Strong HTML5/CSS3 and responsive skills are expected, but they are the floor, not the role.

The role works with US-based stakeholders and requires regular overlap with US hours, particularly around releases.

What You’ll Own

• Hands-on frontend delivery — building and maintaining features across the platform’s React web applications to a production-quality standard
• Component library and design consistency — contributing to and maintaining a shared component library so UI patterns stay consistent across applications
• UI quality — responsive layout, accessibility, cross-browser correctness, performance, and visual consistency
• Frontend stability and performance — troubleshooting production UI issues, optimising rendering and bundle size, and contributing to the long-term technical health of the frontend
• Compliance-aware development — building interfaces within the validated environment, preserving the clarity, auditability, and data-integrity expectations the platform requires
• Codebase fluency — building a deep working understanding of the existing interfaces during the vendor handover and keeping documentation current for the areas you own
• Collaboration — participating in code reviews and design discussions, working closely with backend engineers on API contracts, and partnering with QA on frontend test coverage

What We’re Looking For

This is a hands-on engineering role. We are looking for proven, production frontend capability across the areas below — what you can do matters more than titles held.

Core Engineering Skills (must-have)

• React application engineering — strong, current, hands-on experience designing and building large single-page applications in React (we run a current React version). You understand how React actually renders and re-renders, design
