Overview
A contract opportunity for an experienced Senior Developer to play a pivotal role in the technical delivery of a flagship digital platform within UK Central Government. This role sits within a high-performing, cross-functional team responsible for designing and building scalable, secure, and modern services.
Youll operate with a high level of autonomy and authority, taking ownership of complex development workstreams, contributing to architectural decisions, and mentoring team members. Youll be instrumental in shaping technical practices and ensuring engineering excellence across the full lifecycle.
Key Responsibilities
Lead the design, development, and implementation of secure, performant, and maintainable software components using modern technologies and practices.
Provide technical leadership and hands-on support across the development lifecycle - from requirements analysis and design through to deployment, monitoring, and continuous improvement.
Promote modern software engineering practices, including automated testing, infrastructure-as-code, CI/CD pipelines, clean architecture, and scalable service design.
Drive technical quality, proactively resolving risks and blockers before they impact delivery timelines.
Collaborate with cross-functional stakeholders - including Product Owners, Architects, DevOps Engineers, QA, and third-party partners - to align technical implementation with strategic objectives.
Identify areas for optimisation and improvement, influencing change and implementing new tooling or workflows where necessary.
Provide mentoring, peer review, and technical guidance to developers at all levels within the team.
Required Technical Experience
Advanced hands-on experience in C# and the .NET ecosystem.
Strong back-end development experience, with exposure to Blazor, MVC frameworks, and secure web applications.
Proven track record in cloud-native development, primarily on AWS (plus some exposure to Azure).
Extensive knowledge of Terraform and infrastructure-as-code best practices.
Containerisation using Docker, orchestration with ECS, and familiarity with load balancing and high-availability patterns.
Experience working with MongoDB or similar NoSQL databases.
Proficient in Git, GitHub Actions, and YAML-based pipeline design for CI/CD.
Deep understanding of version control, branching strategies, and test-driven or behaviour-driven development (TDD/BDD).
Ways of Working & Stakeholder Engagement
Demonstrable ability to work independently, manage competing priorities, and take ownership of outcomes.
Proven experience collaborating across multi-disciplinary teams in an Agile delivery environment.
Strong communication skills with the ability to influence and engage both technical and non-technical stakeholders.
Comfortable operating in client-facing settings and leading technical conversations across product and delivery domains.
Experience contributing to or leading internal code reviews, design sessions, and sprint ceremonies.
This role is ideal for an experienced Senior Software Engineer who enjoys solving complex technical problems, thrives in delivery-led environments, and is motivated by the opportunity to work on high-profile government platforms.
Apply now to join a high-performing team and make a tangible impact on a critical national platform.
