Job description

Lead Back-End Developer (C#)

Location : Hybrid – Monthly in-office time (Staffordshire) ¦ UK-based

Salary : Competitive, based on experience

Contract : Full time ¦ Permanent

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 searching for an experienced Lead Back-End Developer to take a hands-on leadership role within one of our product squads, combining technical excellence, delivery focus, and people leadership.

This role is ideal for someone who loves writing high-quality C# code and solving complex technical problems, but also enjoys guiding a team, setting direction, and coaching others to do their best work.

You’ll work across the full lifecycle of our backend services from shaping technical strategy and designing architecture, to diving into code, reviewing pull requests, and unblocking engineers day-to-day. You’ll collaborate closely with Engineering Leadership, Product Managers, and internal stakeholders to ensure the squad delivers robust, scalable systems that meet real business needs.

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.

What You’ll Be Doing

  • Leading a cross-functional squad to deliver features and systems from concept to production
  • Writing clean, scalable, production-grade C# code as part of day-to-day development
  • Line managing Backend Engineers — running 1 : 1s, setting goals, supporting career growth
  • Driving architecture and design decisions, particularly around distributed systems and APIs
  • Defining and maintaining engineering standards, working closely with other Leads and Principals
  • Investigating and debugging complex system behaviour, particularly around finance, concurrency, and distributed messaging
  • Working on event-driven systems with AWS, RabbitMQ, SNS / SQS, and PostgreSQL
  • Improving CI / CD pipelines, observability, and automated test coverage
  • Championing a healthy team culture that values technical rigour, fast feedback, and continuous learning

    • Skills & Experience

    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
  • Experience mentoring or line managing other engineers, or acting as a technical lead

    • How We Work

  • 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

    • Why Join Codeweavers?

  • 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, LinkedIn Learning)
  • 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

    • Who We’re Looking For

    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
  • Want to help grow a healthy engineering culture, not just ship features

    • 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.
