Senior Software Engineer

We’re hiring a Senior Backend Engineer to join a fast-growing, Series C backed developer tools company, trusted by some of the most demanding engineering organisations in the world to protect and accelerate their software delivery.

This is a heavy backend role with real infrastructure ownership. You’ll build and run the services behind the product, from Python and Django through to the AWS infrastructure underneath. The problems cross service boundaries: one week you’re diagnosing a performance regression for an enterprise customer, the next you’re reworking how authentication or billing works at scale.

• Designing event-driven services on Kafka and data pipelines that handle high volumes reliably
• Keeping systems fast, reliable and observable across a distributed architecture
• Owning the infrastructure your services run on, with Terraform and AWS
• Raising engineering standards through testing, code review and mentoring

• 5+ years building and operating distributed systems in production
• Strong Python background, ideally with Django
• Experience with event-driven architectures (Kafka or similar) and high-volume data pipelines
• Comfortable with AWS

• Meaningful equity
• Small, senior team where what you say changes things
• 35 days annual leave, inclusive of optional bank holidays (take them or not)
• Birthday off
• Flexible working hours and flexible remote working
• Pension contributions via Aviva, up to 8%
• Paid sick leave, up to 10 days per year
• Individual private medical insurance via Bupa & Individual healthcare cash plan covering dental and optical
• Paternity and adoption leave
• Income protection & Life insurance
• EV vehicle leasing scheme
• High-performance laptop setup and company swag
