Senior Full Stack Software Engineer (Python / React) in City of London

Skin + Me is a fast-growing, technology-driven start-up on a mission to revolutionise personalised skincare. Our tech team powers all three of our brands (Skin + Me, Hair + Me, and Renew + Me), building everything from our ecommerce platform and internal tools to the systems that run our in-house manufacturing. As we embark on the next phase of our growth, we’re looking for a mid-level to senior Software Engineer to help us design, build, and scale the software that brings life-changing skincare directly to our customers. This is a hybrid role with three days a week in our Paddington HQ (Mon, Tue, Fri) and two days remote.

As a Software Engineer, you’ll join a collaborative, agile tech team working across the full stack to deliver high-impact solutions. You’ll partner closely with Product, Design, and Operations to build new features, improve performance, and scale our systems as we grow. You’ll work primarily in Python while contributing to modern frontend applications, helping shape our architecture and engineering standards as we continue to evolve. This is an opportunity to make a real impact, not just on our products, but on the lives of our customers. The successful candidate will also enjoy working collaboratively and autonomously, and will consistently seek out ways to overcome challenges and obstacles.

What you’ll do:

• You’ll be helping us build and grow our ecommerce platform, comprising multiple brands and domains.
• Collaborate with teammates to design, build, and deploy new features and systems.
• Deliver high-quality, well-tested code that meets both user and business needs.
• Contribute to the evolution of our architecture and engineering practices.
• Partner with Product, Design, and stakeholders to translate ideas into robust, scalable software.
• Work across the stack — backend, frontend, and infrastructure — as part of an end-to-end delivery culture.

Who you are:

We’re looking for someone curious, pragmatic, and collaborative. A problem-solver who loves learning and enjoys working across the stack.

Essential:

• Command of Python and its web development frameworks, for example: Flask, Bottle, Django.
• Experience with relational databases (MySQL preferred) and ORM frameworks (SQLAlchemy, Alembic).
• Working understanding of frontend technologies (HTML5, CSS3, JavaScript).
• Strong understanding of software engineering fundamentals: version control (git), OOP, type systems, unit and integration testing.
• Ability to learn quickly, share knowledge, and adapt in a fast-paced environment.

Bonus Points for:

• 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.
• A resourceful, entrepreneurial mindset: you take initiative and get things done.

Why should you choose Skin + Me?

• A daily challenge – in a thrilling, entrepreneurial start-up environment, no two days will ever be the same.
• Make a difference – work within a revolutionary company that is focused on improving millions of lives.
• Serious commitment to growth – personal development is important to us and we’ll make sure we support your growth, and give you broad experience across your role.

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-fuelled 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.
