Backend Engineer (Python)

London, UK Hybrid (3 days in our Paddington HQ: Mon, Tue, Fri) Stack: Python, Flask, SQLAlchemy, 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 BuildYou'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 Python and React stack, that's the storefront behind Skin + Me and Hair + Me, our flagship brands serving customers at scale.

We're hiring a Backend Engineer to go deep on the server side of this system in our Python / Flask 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 Python (Flask). A non-trivial piece of work you can walk us through and explain well
• Good fundamentals: sound data modelling (SQLAlchemy/Alembic), sensible API design, and an instinct for testing
• Care where it counts: you treat correctness as a feature, because this code generates real prescriptions and orders
• Enough frontend to be useful: comfortable making React changes when a feature needs it (frontend won't be your main focus)
• The stack: Python and Flask; 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 AIAgentic 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.
