Senior Backend Engineer (Contract)

Dunton, Essex – 4 days onsite, 1 day remote

Start: ASAP

⏳ 9 month contract | Inside IR35

£500 per day

We’re supporting a major global automotive organisation as they continue to invest in modernising their finance technology platforms. They’re looking for an experienced Senior Backend Engineer to join a growing engineering team responsible for building scalable, secure backend services that support critical business systems.

This is a hands-on role suited to someone who enjoys solving complex problems, shaping technical solutions, and helping teams deliver high-quality backend systems in a large-scale environment.

The Role

As a Senior Backend Engineer, you’ll play an important role in designing and delivering backend services that are scalable, resilient and secure. You’ll contribute to architectural discussions, lead code reviews, and work closely with engineers across backend, frontend and platform teams to ensure solutions align with broader engineering standards.

You’ll also help guide development practices across the team, ensuring strong engineering discipline around testing, quality and delivery.

Key responsibilities include:

Designing and developing robust backend systems and services
Creating and reviewing technical designs for complex solutions
Leading code and architecture reviews
Working closely with DevOps, frontend and other engineering teams
Improving development workflows and engineering practices
Supporting and mentoring other engineers when needed

Technology

The environment is centred around a modern backend stack including:

Java
Spring Boot
Google Cloud Platform (GCP)
GitHub and CI/CD pipelines
JUnit and automated testing frameworks
SonarQube, Checkmarx and related quality/security tooling
JetBrains IDEs (IntelliJ)
Experience working with TDD / BDD practices and cloud-native architectures is particularly valuable.

What They’re Looking For

5+ years’ experience building and maintaining backend systems
Strong expertise with Java and Spring Boot
Experience designing scalable and resilient architectures
Good knowledge of Git-based workflows and CI/CD
Experience working with cloud platforms (ideally GCP)
A strong focus on code quality, testing and maintainability
Ability to work independently while contributing to a collaborative team

Experience in regulated environments such as finance or lending would be beneficial but isn’t essential.

If you’re an experienced backend engineer looking to work on large-scale financial systems within a well-established organisation, this is a great opportunity to contribute to a modern engineering environment with strong technical standards.

Sounds like fun? Please apply with your CV and I will arrange a call to discuss in more detail.
