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.
• Growth Mindset
• Typically coming from a 3–6 year software engineering background, but depth of experience and technical capability are valued more than years served

Technical Skills:

Strong experience with:

• Python
• Flask
• RESTful API development
• Relational databases (MySQL preferred)
• Backend service architecture
• Automated testing and code quality practices

Desirable experience with:

• React
• AWS
• Docker
• Modern cloud-native development environments

What’s on Offer

• Competitive salary plus meaningful equity package
• Hybrid working with flexible hours
• 25 days holiday plus bank holidays
• Daily meals provided in the office
• £500 annual learning budget
• Health and wellbeing support, including a healthcare plan and cycle-to-work scheme
• Family support benefits, including childcare cost-saving schemes
• Regular team events and a strong, collaborative culture
