Lead Scala Engineer

About the job you're considering

Capgemini is recruiting highly skilled Lead 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.

In your role as Lead Engineer, you will go beyond delivery‑shaping technical strategy, mentoring engineers, and driving innovation across projects. You will influence best practices within our engineering community and play a key role in defining how we build and deliver modern digital services.

Working location will vary depending on your role, personal needs, and business requirements. Typically includes a mix of company offices, client sites, and remote work from home.

If your location is Telford or Worthing you will be expected to work from the office 40%–70% of the time. For all other locations you need to be prepared to come into the Telford or Worthing office once or twice a month (Lead engineers more frequently). Fully remote working (100% from home) is not permitted.

As we align closely with customer requirements— which may change over time—you will need to remain flexible.
