Mitra Bio is building the future of skincare through epigenetics, longevity science, and data. Backed by Khosla Ventures, Illumina, and Innovate UK, we help people better understand their skin over time using simple, non-invasive skin sampling and advanced data analysis. Our goal is to make highly personalised skincare more effective, accessible, and science-driven.
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.
What you’ll own:- 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
- 5+ years of experience as a full-stack or frontend-focused engineer
- Strong understanding of modern frontend development and product-focused UI/UX
- 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.
Benefits:- 25 days of annual leave, plus public holidays in England and Wales
- Join a fast-growing, mission-driven startup at an early stage
- Build a product that directly impacts consumers in a meaningful way
- High ownership, autonomy, and direct impact on the product and customer experience
- A collaborative, ambitious team of scientists, engineers, and operators building something genuinely new
- Strong in-person/hybrid culture, fast feedback loops, and zero bureaucracy
- Backing from world-class investors and experienced founders
- A fast-moving environment where great ideas can quickly become reality
- Opportunity to shape both the product and engineering culture from the ground up
