Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Full Stack Engineer - **Company:** Mitra Bio - **Location:** London, UK (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Artificial Intelligence, Application Integration Architecture, Software Quality, Code Review, Continuous Integration, Design of User Interfaces, Next.js, Shopify, TypeScript, Web Application Frameworks, ReactJS, Backend, Front End Software Development, Api Design, Software Version Control - **Published:** May 16, 2026 - **Apply:** https://uk.indeed.com/viewjob?jk=a2144d3942e92442 ## About the Role Do you have experience in UX?, We're looking for a full-time Senior Full Stack Engineer with exceptional frontend and product instincts to help shape the next generation of our customer experience. This is not a "ticket-taking" engineering role. We're looking for someone senior, scrappy, creative, and deeply product-minded - someone who cares as much about the elegance of the experience as the quality of the code underneath it. You'll help build a luxury-grade digital product used by real consumers, sitting at the intersection of science, beauty, AI, and commerce. You'll report into our Head of Engineering and work closely with Product, Engineering, Data Science, and leadership to translate complex platform capabilities into seamless, intuitive experiences. One day you might be refining a high-performance frontend flow; the next, improving API architecture, building a Backend-for-Frontend layer, or shaping how our platform evolves as we scale. We're especially excited by engineers who thrive in ambiguity, move quickly without sacrificing quality, and enjoy ownership. The right person will be equally comfortable obsessing over UX polish, collaborating on backend systems, contributing to architectural decisions, and rolling up their sleeves to ship., * 5+ years of experience as a full-stack or frontend-focused engineer * Strong understanding of modern frontend development and product-focused UI/UX * Highly proficient in TypeScript and modern JavaScript frameworks (ideally Next.js/React) * Experience integrating APIs and building scalable web applications * Experience with Shopify, headless commerce, or customer-facing e-commerce products * Strong engineering fundamentals across testing, version control, CI/CD, and code quality * Strong user empathy and a sharp eye for detail * Works well in fast-moving startup environments where priorities evolve quickly We're particularly interested in hearing from people who have built polished consumer experiences, thrive in startup environments, and want to help create something category-defining. Our team is primarily hybrid in London, but for this role we're also open to strong candidates located elsewhere in the UK who prefer to work primarily remotely. ## Description * Building and delivering a premium, customer-facing web experience with exceptional UI/UX quality, performance, and responsiveness * Developing frontend integrations and Backend-for-Frontend (BFF) services connecting our applications with APIs, e-commerce systems, and internal platforms * Driving frontend quality through testing, CI/CD, code reviews, and engineering best practices * Contributing to technical and product direction across frontend and backend architecture ## Related Videos - [WeAreDevelopers LIVE - Markdown, Liquid and Checkouts](https://www.wearedevelopers.com/videos/1814-wearedevelopers-live-markdown-liquid-and-checkouts) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Teini - an extremely small webshop leveraging awesome and free tech](https://www.wearedevelopers.com/videos/286-teini-an-extremely-small-webshop-leveraging-awesome-and-free-tech) - [From Zero to Hero: NextJS 13 and Tailwind CSS for Beginners](https://www.wearedevelopers.com/videos/766-from-zero-to-hero-nextjs-13-and-tailwind-css-for-beginners) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Fullstack Developer Salary UK](https://www.wearedevelopers.com/magazine/251-fullstack-developer-salary-uk) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
