We're building a platform that companies use to create marketplaces that help people find the right kind of provider and book an appointment. Payer and employer partners deliver it to their members inside their own sites and apps, through embeddable experiences, SDKs, an API, and
an MCP server.
You'll build those surfaces and the API behind them. The work spans the embeddable widget clients place on their sites, the preview app that demonstrates it, the questionnaire and booking flows, SDKs, and a remote MCP server.

This is a hands-on, AI-native role: you'll use coding agents and reusable AI skills every day to ship faster without trading away quality or security.

• Responsibilities:

  - Build the embeddable widget as web components or iframes, with style isolation, Content Security Policy compatibility, a postMessage protocol, and versioning that won't break partner pages.

  - Generate SDKs from the OpenAPI contract, write developer documentation, and build the sandbox experience for partner developers.
  - Ensure proper handling of PHI.
  - Write unit, integration, and end-to-end tests, ship through CI/CD, monitor what you build, and support incident response.

• Mandatory Skills Description:

  - 6+ years of full-stack engineering experience shipping production web applications.
  - Experience building embeddable widgets, third-party-hosted web components, or SDKs that run inside other companies' products.
  - Strong TypeScript and React, plus backend services in Python (e.g., FastAPI).
  - Command of the web platform for embedding: custom elements and Shadow DOM, iframe sandboxing, Content Security Policy, and postMessage.
  - REST API design with OpenAPI, including SDK generation from specs. GraphQL experience is a plus.
  - Practical knowledge of OAuth 2.0, OpenID Connect, and SSO.
  - Experience working with PII and/or PHI under HIPAA.
  - Daily use of AI coding tools like Claude Code, with the judgment to keep AI-assisted code correct, tested, and secure.

If you're passionate about React, enjoy solving challenging problems, and want to build the future of online gaming—we'd love to meet you.

About the Product

You'll join the team behind an AI size and fit product for fashion brands. Its size advisor combines custom algorithms, product data and shopper preferences to recommend the right size, so retailers sell more and deal with fewer returns. Well-known luxury fashion brands use it on their online stores, and merchants of every size install it through our Shopify app. We're now building virtual try-on as well.

We're a small team spread across the UK, Italy, Germany and Ukraine, so you'll work directly with our CTO, our designer and our product lead.

The Role

We're looking for a strong junior frontend developer who's ready to take a task from ticket to release. Most of your time will go into our Shopify app, which merchants use inside their Shopify admin to set up size charts and configure the size advisor. You'll also work on requests from our brand clients for the size advisor widget that runs on their product pages, and you may help with virtual try-on as it develops.

You'll plan your work in Linear, open pull requests that a teammate reviews, and use AI coding tools every day. We use Claude Code a lot, and we expect you to understand every line it writes for you.

What You'll Do

• Build new features in our Shopify app, such as size chart creation and editing, merchant onboarding, recommendation settings and dashboards.
• Fix bugs and work through the backlog, keeping the app in line with Shopify's Polaris design system and Built for Shopify guidelines.
• Work on our theme app extension and web pixel, the parts of the app that run on merchants' storefronts.
• Deliver customisations, fixes and small features on the size advisor widget for our brand clients.
• Turn Figma designs into responsive, accessible interfaces that work across browsers.
• Write tests for the code you change, using Vitest and Playwright.
• Take part in code reviews, both giving and receiving feedback.

What We're Looking For

• At least a year of commercial experience building React applications, or shipped projects that show the same level.
• Working knowledge of TypeScript.
• Solid JavaScript, HTML and CSS/SCSS, including responsive layouts and cross-browser issues.
• Experience working with REST APIs and handling async data, including loading and error states.
• Basic GraphQL: you can read and write queries (Shopify's Admin API is GraphQL).
• Comfortable with Git, pull requests and code review.
• Good spoken and written English. It's our working language across four countries.
• Hands-on experience with AI coding assistants, and the judgement to check what they produce.
• Working hours that overlap with UK and Central European time. Our daily stand-up is at 9.30am CET (8.30am UK time).

Nice to Have

• Experience building Shopify apps: Remix or React Router 7 (Shopify's current app template), App Bridge, Shopify CLI and theme app extensions.
• Polaris, either Polaris React or the newer Polaris web components.
• Node.js on the server, plus basic Prisma and PostgreSQL.
• Redux Toolkit, Vite and Storybook.
• three.js or React Three Fiber.
• Accessibility (WCAG) and internationalisation (i18n).
• An interest in fashion and e-commerce.

Our Tech Stack

• Shopify app: React, TypeScript, Remix, Polaris, App Bridge, Prisma, PostgreSQL, Vite, pnpm, Biome
• Size advisor widget: React, TypeScript, Redux Toolkit, SCSS, Vite, three.js and React Three Fiber, plus our own component library in Storybook
• Testing: Vitest, Testing Library, Playwright
• Tools: GitHub, Linear, Figma, Claude Code

What We Offer

• Visible work: what you build runs on the online stores of some of the best-known names in fashion.
• Mentoring from our CTO, and a careful review on every pull request.
• A team that releases to production several times a week, so you see your work live within days.

Our Values

• Integrity: We respect ourselves and others, and we do the right thing because it's the right thing to do.
• Own it: We don't pass the buck. The team depends on you and trusts you, and we're collectively accountable for the good outcomes as well as the bad.
• Execution: We want to create something worth creating, so we execute, monitor, learn, adjust and repeat. Iteration is at the heart of everything we do.
• Intellectual rigour: We're passionate about what we do. We encourage rigorous debate and make decisions based on logic, data and facts.
• Collaboration: We value the team over the individual. No one should be afraid to ask for help or unwilling to help others, and that's how we build the highest-quality systems.
