Worthing, Leeds, Manchester, Bristol, London, Birmingham, Telford# Senior Scala Engineer Capgemini are recruiting highly skilled Lead and Senior Engineers to join their dynamic team, delivering solutions for a major public sector client. This is an opportunity to work on meaningful projects that impact millions of people, in an environment that values innovation and collaboration.

Our mature Agile environment provides a supportive space to collaborate with specialists from other disciplines. You’ll be part of a culture that encourages continuous improvement, knowledge sharing, and technical excellence.

Our Senior Engineer, you’ll focus on delivering critical digital services from cradle to grave working on a variety of projects for wide reaching Public Services.
** Hybrid working:
** Your working location will vary depending on your role, personal needs, and business requirements. This will typically include a mix of company offices, client sites, and remote work from home. If your location is Telford or Worthing (please note the Worthing office will relocate to Brighton & Hove in the second half of 2026) you will be expected to work from the office between 40% and 70% of the time.

For all other locations you need to be prepared to come into the Telford or Worthing office once to twice a month (Lead engineers more frequently). As we align closely with customer requirements—which may change over time—you will need to remain flexible. Please note that fully remote working (100% from home) is not permitted.##
** Your role*
* • Develop and maintain Scala services using frameworks like Play, Akka, and functional programming principles.

• Write high-quality, tested code with TDD/BDD and tools such as Scala Test.

• Design and optimise microservices for performance, scalability, and reliability.

• Manage builds and deployments using SBT, CI/CD pipelines, and containerisation (Docker/Kubernetes).

• Mentor junior engineers on Scala best practices and support their development.

• Collaborate with stakeholders to deliver solutions aligned with business needs.

• Ensure operational excellence through monitoring, troubleshooting, and continuous improvement.

Our culture  We’re looking for people who are learning focused, challenge the status quo and are constantly looking to shape their working environment to make it an exciting, fun and interesting place to work.
Keeping things fresh is something we encourage in our working practices, but the culture of continuous improvement is equally as important in our technical approach to building and delivering modern digital services. Your knowledge and experience will be used to change the way we build solutions including utilising new tools and technologies to solve new problems or improve existing services.
Working on our services means you’ll be part of a team, but you’ll also be a part of communities of interest. This means you’ll always have people on hand to share and discuss ideas and get help when needed. The engineering organisation is engineering led, supporting each other through coaching and mentoring, so if you want to change something it’s within your power to do so.##
