Senior Full Stack Software Engineer (Python / React)

Skin + Me is a technology-driven start-up on a mission to revolutionise personalised skincare. We’ve delivered millions of treatments across our multi-brand ecosystem (Skin + Me, Hair + Me, Renew + Me), powered by a proprietary stack that runs everything from our e-commerce engine to our in-house manufacturing. As we embark on the next phase of our growth, we’re looking for a Senior Software Engineer to join our high-leverage team. This is a hybrid role with three days a week in our Paddington HQ (Mon, Tue, Fri) and two days remote.

The mission

At Skin + Me, we value shipped impact over "hours spent typing”. Your goal is to use the best agentic tools to speed up the mundane so you can spend your time solving the hard problems: scale, experimentation and architecture.

What you’ll do

• Direct Agentic Workflows: Use agentic tools to navigate, plan, refactor, and ship features across our Python / React stack while drastically increasing your technical leverage.
• Full-Stack Ownership: Architect and deploy end-to-end features, from backend logic and database schemas to modern frontend experiences.
• Lead Engineering Evolution: Help define our "AI-native" development standards and mentor the team on high-velocity delivery.

Who you are

• The AI Edge: You are a power user of agentic AI. You know how to orchestrate edits across multiple files and identify where an LLM is hallucinating.
• Pragmatic Architect: You have the seniority to know when to trust an agent and when to step in. You value clean code, type systems, and robust testing.
• High Agency: You’re a problem-solver who thrives in a fast-paced, autonomous environment.

Technical skills

• Command of Python and its web development frameworks e.g. Flask, Django.
• Experience with relational databases (MySQL preferred) and ORM frameworks (SQLAlchemy, Alembic).
• Experience with TypeScript and React.
• Experience building and maintaining frontend design systems.
• Familiarity with containerisation (Docker) and cloud platforms (AWS preferred).
• Understanding of modern web architecture and performance optimisation.

Why Skin + Me?

• High Leverage: We give you the best tools and the autonomy to use them.
• Make a difference: Work within a revolutionary company that is focused on improving millions of lives.
• Equity: Every employee has a stake in the business.
• Perks: Free breakfast and lunch (office days), dog-friendly HQ, 25 days holiday, and a £500 annual development budget.

Benefits

• 25 Days Holiday (+ all the usual Bank Holidays) – It’s important to take a break and recharge, that’s why we offer a generous holiday allowance.
• Free Breakfast & Lunch – It’s important you are well fueled for the day so we’ve got your breakfast and lunch covered. Plus drinks and snacks are available too!
• Hybrid working to give you flexibility – We are all remote on Wednesday and Thursday. When we are in the office on Monday, Tuesday and Friday our core hours are 10-4. If you’re an early bird you can do 7-4, and if you’re a night owl 10-7 is fine too. Need more flexibility around your life – just let us know.
• Equity – We offer a competitive salary and a generous share award package that means every employee has a stake in the business.
