Who we are

Healthcare needs a better rhythm: one that keeps care continuous and deeply human. Heidi is building an AI Care Partner that works alongside clinicians to make that possible.

We’re 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’re growing in the US, UK, Canada, and Europe, partnering with leading health systems including the NHS, Beth Israel Lahey Health, and Monash Health.

Join Heidi Health to build responsive, accessible user interfaces for our multi-locale healthcare platform using React, Next.js, Type Script, and Tailwind CSS
. You'll 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’ll do

• Build Components: Develop and maintain simple, responsive UI components using React and Type Script under guidance from senior developers.

• AI-Assisted Development: Proactively leverage AI coding tools (e.g., Git Hub 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 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're 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 Type Script (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. Our strength is in our differences. We're proud to…
