Senior Full Stack Engineer (Node / Typescript / React)

London, UK · Hybrid (3 days in our Paddington HQ: Mon, Tue, Fri) · Stack: Node.js, TypeScript, React, MySQL, AWS

In 2018 we set out to solve a problem millions of people faced: not just struggling with their skin, but struggling to navigate skincare at all. We combined dermatology, pharmacy and technology into something simpler and genuinely personalised, and proved expert‑led care could reach people who'd never had access to it. Today, +Me is the company behind Skin + Me, Hair + Me and Renew + Me, with more on the horizon. We're not building a single brand. We're building a category. We've delivered millions of treatments, we're profitable and growing fast, and we're expanding the engineering team to match.

What you’ll build

You’ll join the team behind our core commerce and clinical journey: the ecom stack, consultation engine, patient and prescription systems, and order generation. This is where customers discover us, complete a clinical consultation, subscribe, and receive their personalised treatment, at real consumer scale. On our Node and React stack, that's the storefront behind Renew + Me, Skin + Me Germany and the new verticals we're launching, so there's real greenfield work as we expand into new brands and markets. We're hiring a Senior Full Stack Engineer to own features end‑to‑end across this system in our Node / TypeScript / React stack: backend services and data models through to the customer‑facing frontend, with the judgement to make sound architectural calls as we scale to more brands and more customers.

What you’ll do

• Own features end‑to‑end: from backend services and data schemas to the React frontend, across systems like checkout, subscriptions, and the consultation‑to‑prescription flow.
• Scale what's working: keep the platform fast, correct and resilient through new brand launches and rising volume, and make the architectural calls that keep it that way.
• Lift the team: clean, well‑tested code and honest reviews that help the engineers around you ship with confidence.

What we’re looking for

• Depth and breadth: strong, recent, hands‑on full‑stack experience. You're genuinely capable across backend and frontend, not just one side.
• Engineering judgement: clean code, clear API design, sound data modelling, and the instinct to pick the simple, robust solution over the clever one.
• Shipped impact: features you owned and shipped that moved something real for customers or the business.
• Care where it counts: you write carefully when correctness matters, because here a bug can mean a wrong prescription, not just a broken page.
• The stack: production command of Node.js, TypeScript and React; relational databases (MySQL ideal); comfort with AWS and Docker.
• Clear communication: most of our work happens in PRs, design docs and async decisions, so writing clearly matters.
• Roughly 6+ years building software in production. We read for depth and shipped impact, not years.

How we work

We're a small, experienced engineering team working closely with product, clinical and operations. We care about craft: clean code, honest reviews, and owning what you ship through to production. And because our software turns a clinical consultation into a real prescription and a treatment someone receives, correctness and care aren't optional here. They're the job.

How we use AI

Agentic tools like Claude Code and Codex are a standard part of how we work, and we're leaning into them hard: we automate the routine so we can spend our energy on the harder problems. You'll need to be comfortable working this way, and real skill with these tools is a genuine advantage we value. But it's a multiplier on strong engineering judgement, not a substitute for it, and never a prerequisite. If it's newer to you and you're keen to grow, we'll back you.
