Frontend Website Developer in London

This is a website development role working within the Go-To-Market (GTM) team.

Heidi is building an AI Care Partner that works alongside clinicians to make healthcare continuous and deeply human. We are a team of doctors, engineers, designers, researchers, and creatives building tools that help clinicians stay focused on what matters most: their patients. In just 18 months, Heidi has given back more than 18 million hours to healthcare professionals — supporting 73 million patient visits in 116 countries. Today, more than two million patient visits each week are powered by Heidi worldwide. Backed by nearly $100 million in funding, we are growing in the US, UK, Canada, and Europe, partnering with leading health systems including the NHS, Beth Israel Lahey Health, and Monash Health.

The Role: Join Heidi Health to build responsive, accessible user interfaces for our multi-locale healthcare platform using React, Next.js, TypeScript, and Tailwind CSS. You will work closely with our designer implementing pixel-perfect components while growing your skills in internationalisation, Sanity CMS Studio customisations, and modern frontend architecture.

What you will do:

• Build Components: Develop and maintain simple, responsive UI components using React and TypeScript under guidance from senior developers.
• AI-Assisted Development: Proactively leverage AI coding tools (e.g., GitHub Copilot, Cursor, ChatGPT) to accelerate boilerplate generation, write unit tests, and troubleshoot errors while ensuring code quality.
• UI Implementation: Assist in implementing responsive designs from Figma, focusing on accurate styling using Tailwind CSS and ensuring basic cross-browser compatibility.
• Localisation Support: Assist with content configuration in our internationalisation systems (i18n), focusing on content deployment for our 10+ locales.
• CMS Assistance: Support the configuration of the Sanity CMS Studio, including content structure, basic custom input components, and maintaining editor workflows.
• Performance Support: Assist the team in optimising website performance, focusing on image optimisation, lazy loading, and initial analysis of Core Web Vitals reports.
• Tracking & SEO: Implement pre-defined analytics tracking code (GA4) and apply fundamental technical SEO best practices (e.g., meta tags, structured data).
• Collaboration: Participate in API integration discussions and assist with basic data fetching tasks.
• Code Quality: Write clean, well-commented code, adhere to team coding standards, and actively participate in team code reviews.

What we are looking for:

• 1-2 years of professional or advanced project-based frontend development experience.
• Foundational knowledge of React and modern JavaScript (ES6+).
• Familiarity with server-side rendering concepts and frameworks (Next.js preferred).
• AI Fluency: Comfortable using AI tools to explain code logic, refactor functions, and speed up daily development workflows.
• Experience with CSS frameworks (Tailwind CSS, CSS Modules, or similar) is a plus.
• Basic understanding of responsive design principles and browser debugging tools.
• Experience with Git workflows (cloning, branching, committing) and collaborative development.
• Eagerness to learn and strong communication skills for asking clarifying questions.

Preferred qualifications:

• Exposure to TypeScript (or willingness to learn immediately).
• Experience with AI-native IDEs (e.g., Cursor) or effective prompt engineering for code generation.
• Familiarity with headless CMS platforms (Sanity, Contentful, or similar).
• Basic awareness of accessibility standards (WCAG) and internationalisation concepts.
• Experience in healthcare or regulated industries.
• Completed relevant projects showcasing component development and styling proficiency.

Heidi is dedicated to creating an equitable, inclusive, and supportive work environment that brings people together from diverse backgrounds, experiences, and perspectives.

The way we work:

• Own Your Practice: Ideas rise on merit, not title, and everyone shares responsibility for the standards we set together.
• Move Fast, Stay Steady: We move quickly but never at the cost of trust. Progress only matters if people can depend on what we make.
• Make Others Better: Honest feedback, steady support, and shared growth keep our teams improving together.

Why you will flourish with us:

• Real product momentum. We are not trying to generate interest, we are channeling it.
• Equity from day one. When Heidi wins, you win. You will share directly in the success you help create.
• Unmatched impact. Play a pivotal role in defining and scaling customer success at a critical growth moment - all while working on a product that delivers tangible value to clinicians and patients every day.
