The Senior Backend Developer will be part of a product-focused engineering team working on customer-facing, mission-critical systems at scale. The emphasis is on strong software engineering fundamentals rather than framework-driven development - clean code, thoughtful design, and pragmatic problem-solving matter far more than ticking boxes on a tech stack.

As a Senior Backend Developer, you’ll be working in an environment that is collaborative, fast-moving, and delivery-focused where engineers are trusted to own features end-to-end, contribute to technical direction, and make sensible architectural decisions as the platform evolves. There’s a genuine balance between autonomy and teamwork, with space to experiment, learn, and continuously improve how things are built.

Senior Backend Developer - Key Requirements:

• Strong experience building Back End services using Python (or another modern Back End language)
• Solid grounding in software engineering fundamentals, including data structures, algorithms, and object-oriented design
• Experience designing, building, and maintaining scalable Back End systems
• Comfortable working with APIs, databases, and distributed systems
• Strong problem-solving skills and a pragmatic approach to debugging and refactoring
• Experience working with version control, testing practices, and code reviews
• Product-minded - able to think beyond the code and understand real user impact
• Experience working in fast-paced environments with evolving requirements
• Collaborative communicator who enjoys working closely with engineers, product, and design

Senior Backend Developer - Salary & Benefits:

• Basic salary up to £100k
• Bonus and/or share options
• Private medical insurance
• Generous holiday allowance
• Flexible hybrid working model
• Learning & development budget
• Strong wellbeing benefits and additional perks

If you’re a Senior Backend Developer looking for a role where you can focus on fundamentals, build meaningful products, and grow alongside a scaling tech business with serious investment behind it, this is a strong opportunity.

We are an equal opportunities employer and welcome applications from all suitably qualified candidates, regardless of race, sex, disability, religion/belief, sexual orientation, or age.
