About the job you're considering

Capgemini are 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. 

Our Lead Engineer, you’ll go beyond delivery—shaping technical strategy, mentoring engineers, and driving innovation across projects. You’ll influence best practices within our engineering community and play a key role in defining how we build and deliver modern digital 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

• Architectural Ownership: Define and govern the technical architecture for Scala-based solutions, ensuring alignment with enterprise standards and long-term scalability.  
• Technical Strategy: Set the roadmap for Scala adoption, tooling, and best practices across teams; influence technology choices at programme level.  
• Cross-Team Leadership: Coordinate multiple squads, ensuring consistent delivery and technical quality across all Scala projects.  
• Complex Problem Solving: Tackle high-level design challenges, performance bottlenecks, and integration issues in distributed systems.  
• Stakeholder Influence: Represent engineering in senior forums, providing technical insight and shaping strategic decisions.  
• Capability Building: Drive recruitment, training, and upskilling initiatives for Scala engineers; establish communities of practice.  
• Innovation Leadership: Introduce emerging Scala libraries, frameworks, and patterns to improve productivity and maintain competitive edge. 

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.

Your skills and experience

• Strong professional experience with Scala and functional programming 
• Experience designing and consuming REST APIs; JSON validation/serialisation using Play JSON or Circe.  
• Designing for and querying relational databases such as PostgreSQL and/or NoSQL databases such as MongoDB.

• Familiarity with SBT for build/CI/CD automation and GIT with branching strategies.  
• Solid understanding of web/HTTP, web security best practices, and performance considerations.  
• Familiarity with cloud-based infrastructure, CI/CD pipelines, and containerisation.  

Lead Engineer will also demonstrate:  

• Ability to design and govern complex Scala-based architectures for scalability and maintainability.  
• Skill in setting technology roadmaps and influencing decisions across multiple teams.
