Lead Software Developer (SC Eligible/SC Cleared)

About Scrumconnect Consulting Scrumconnect Consulting is a multi-award-winning digital consultancy, recognised for delivering impactful and innovative technology solutions across UK government departments. Our work has positively influenced the lives of over 40 million UK citizens.

We are passionate about user-centred design, agile delivery, and building digital services that make a real difference. Our teams work at the forefront of innovation, helping organisations transform and deliver high-quality, scalable solutions that truly matter.

Overview We're looking for a hands-on Lead Software Developer to lead engineering on high-volume public services for our UK government clients. You'll set the technical direction for your team, write code alongside them, and make sure what you build holds up under real-world volume.

Much of the work means connecting modern Spring Boot services to long-standing Legacy systems, so knowing how to modernise safely counts as much as building something new. Key Responsibilities Lead the technical work of one or more agile teams, from design and build through to running in production.

Set and uphold engineering standards, including code reviews, test-driven development, CI/CD, and maintainable code. Lead the design of Spring Boot services and robust data access layers using Spring Data JPA. Integrate modern services with Legacy SOAP/XML systems, using incremental patterns such as Strangler Fig.

Drive performance across database queries, caching, overnight batch jobs, and high-volume transaction processing. Work with the client's architects on design, tooling, and decisions, and challenge choices that add complexity without adding value.

Build to the client's technical standards and reference architecture. Support live services, leading incident response and longer-term resilience fixes. Work closely with product managers, designers, testers, and other team members to deliver user-focused services.

Coach and mentor developers, and share knowledge so it stays with the client team. Contribute to the Scrumconnect engineering community. Required Skills and Experience Proven experience leading engineering teams and building production systems with Java and Spring Boot.

Deep practical knowledge of Spring Data JPA, including entity mapping, transactions, auditing, and lazy/eager loading trade-offs. Experience integrating modern services with Legacy SOAP/XML systems and modernising them incrementally.

Hands-on AWS experience, ideally EKS, RDS PostgreSQL, SQS, SNS, and S3, with infrastructure as code such as Terraform. ...
