Back End Developer

Backend Engineer | Hybrid (3 days a week in London) | Up to £90,000 + Meaningful Equity | Python + Flask

We’re currently working with a fast-growing, technology-driven startup that’s on a mission to transform personalised consumer experiences through innovation and scale. Their platform powers a multi-brand ecosystem, supported by proprietary technology spanning e-commerce, data, and in-house operations.

As they enter their next phase of growth, they’re looking for a strong backend engineer to join a high-impact team. They embrace modern, AI-assisted development workflows and treat agentic tools as a core part of how they build and ship software.

This is a hybrid role, with three days per week in a Central London office and two days remote.

What You'll Do:

Build Core Platform Services

Design and develop the APIs, services, and data models that power customer consultations, prescriptions, subscriptions, and order generation.

Own Features End-to-End

Take backend features from concept through to production, ensuring they remain reliable, scalable, and maintainable once live

Write clean, well-tested code that other engineers can easily understand, extend, and build upon

Support Full Product Delivery

While backend engineering is the primary focus, you'll also contribute to React-based frontend features when required to deliver complete customer experiences

Develop software where accuracy and reliability matter, supporting systems that directly impact customer treatments and orders

Who You Are:

Strong Backend Engineer

You have solid commercial experience building production backend services and APIs using Python, and can confidently discuss complex projects you've delivered

You understand data modelling, API design, testing practices, and how to build maintainable software at scale

You build defensively and care about correctness, recognising the real-world impact software defects can have on customers

Comfortable working closely with engineers, product teams, operations, and clinical stakeholders while documenting decisions clearly through PRs and technical documentation.
