Backend Engineer (Node / Typescript) in City of Westminster

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

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 Backend Engineer to go deep on the server side of this system in our Node / TypeScript stack: the APIs, data models and services behind consultations, prescriptions and orders. You'll learn fast alongside experienced engineers who'll back your growth, and you'll be comfortable making frontend (React) changes when a feature needs it, but backend is your craft.

What you'll do

• Build the services behind the journey: APIs, data models and services powering consultations, prescriptions and order generation, with support from senior engineers.
• Ship and own: take backend features from ticket to production and keep them fast, correct and healthy once they're live.
• Write code others build on: clean, well-tested, and clear enough for the next person to pick up.

What we're looking for

• Backend depth: solid, recent, hands-on experience building backend services and APIs in Node.js/TypeScript. A non-trivial piece of work you can walk us through and explain well.
• Good fundamentals: sound data modelling, sensible API design, and an instinct for testing.
• Care where it counts: a defect in these services can mean a wrong prescription or a mis-shipped order, so you build defensively.
• Enough frontend to be useful: comfortable making React changes when a feature needs it (frontend won't be your main focus).
• The stack: Node.js and TypeScript; relational databases (MySQL ideal); some exposure to AWS/Docker is a plus.
• Clear communication: much of our work is written (PRs, docs), so explaining a decision crisply matters.
• Roughly 3-6 years building software in production. We read for depth in your area, 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.

Compensation & benefits

• We pay competitive base salaries and back them with meaningful equity, so your upside grows with the company you're helping build.
• Equity: a meaningful stake in a profitable, Series B-backed business that's growing fast, with flexibility on your cash/equity mix.
• Time off: 25 days holiday plus bank holidays.
• Hybrid & flexible: three days together in Paddington (Mon, Tue, Fri), remote Wed/Thu, core hours 10-4 with flexibility around them.
• Fuelled: free breakfast and lunch on office days, plus snacks and drinks.
• Growth: a £500 annual personal development budget.
• Family & health: healthcare cash plan, cycle-to-work, and a workplace nursery scheme (save tax/NI on childcare).
• The extras: a dog-friendly HQ (two resident pups), an active Culture Club, and heavily discounted products for you and 10 friends & family.

How we hire

We keep it short and respect your time: Intro call with our engineers (25-30 mins), including a short system-design chat. A conversation with our Director of Software Engineering (30 mins). A practical take-home task, in your own time. Onsite at our Paddington HQ to review your task and meet the team.

Great engineers come from all kinds of backgrounds. If this resonates, even if you don't tick every box, we'd love to hear from you. Sound like you? We'd love to hear from you.
