Who We Are
At Codeweavers, we’re powering the future of automotive commerce. Our SaaS platform connects car buyers, retailers, lenders, and manufacturers through thousands of digital solutions used across the UK and increasingly, around the world.
We’re a team of curious problem-solvers and lifelong learners who believe that engineering excellence comes from craft, not complexity. Whether it’s refining finance calculations, integrating with external platforms, or streamlining onboarding workflows, our developers are at the heart of making car buying easier for everyone.
About the Role
We’re looking for experienced back-end developers who love working with C# to join our growing engineering team. You’ll play a hands-on role in designing and delivering reliable, well-engineered services, while contributing to a strong and supportive developer culture.
This isn’t a job where you’ll just be handed a spec. You’ll collaborate with product owners, internal users, and other engineers to deeply understand the business problems and shape the right solutions.
We’re currently growing across several key product areas:
Finance Calculations & Lender Integrations – Building robust finance calculation engines and secure, compliant integrations with major UK lenders
Retailer E-Commerce Tools – Delivering fast, reliable tools for retailers to manage online vehicle sales, including quoting and checkout experiences
Client Onboarding & Automation – Creating back-office systems that simplify onboarding and reduce operational workload across the platform
If you’ve worked in fintech, financial modelling, or any domain where business logic, data flow, and performance are key, you’ll feel right at home.
Collaborating with product owners and internal users to understand real business needs
Writing clean, performant, and maintainable C# code
Designing thoughtful APIs and distributed services
Working on cloud-first, event-driven systems using AWS, RabbitMQ, and SNS/SQS
Making smart, incremental changes, deployed often and safely using CI/CD pipelines
Helping define and evolve our engineering standards and architectural direction
We’d love you to have some of the following:
Strong experience writing production-grade C# code
An understanding of event-based architectures and message queues (e.g., RabbitMQ, AWS SQS/SNS)
Database experience (Postgres, Cassandra, or similar)
Experience designing and building APIs consumed by external clients or internal teams
A pragmatic mindset, balancing technical elegance with delivery goals
An interest in test automation, CI/CD, and continuous delivery practices
Some exposure to working in fintech, automotive, or other complex domains
Small, multi-disciplinary squads aligned to product areas
A culture of rapid feedback, continuous deployment, and shared learning
Dedicated “Kaizen” time every week to focus on self-improvement
Collaborative code reviews and regular architecture discussions
A culture where healthy challenge is welcomed, and assumptions get tested
Hybrid working: mostly remote with occasional in-office visits
23 days holiday + bank holidays + birthday off + wellness day
Extra holiday for each year of service
Access to learning resources (Pluralsight, books, conferences)
Dedicated weekly learning time
Regular social events including our legendary sports day and Christmas party
Transparent, respectful culture where engineers shape the direction of their work
We’re after thoughtful engineers who:
Want to make meaningful contributions, not just write code
Ask questions, seek feedback, and care about the ‘why’ behind the work
Enjoy digging into complex problems and making them simpler
Are comfortable working collaboratively in a transparent, respectful environment
STRICTLY NO AGENCIES PLEASE
We work with a carefully selected set of recruitment partners and are not looking to add to our PSL.
We do not accept unsolicited CVs sent to the recruitment team or directly to a hiring manager. We will not be responsible for any fees related to unsolicited submissions.
