The Senior Software Developer role sits within HMRC’s Chief Digital Product Office (CDPO), in the Business Developed Applications (BDApp) team. This team designs, builds and maintains software solutions that support HMRC’s customer-focused strategy with a portfolio that includes around 140 products, ranging from new applications to legacy systems.

Job description

The role is central to delivering technological change while ensuring operational stability. It involves leading the design and delivery of BDApps, maintaining and enhancing existing applications, and driving improvements to reduce technical debt and ensure compliance with legislation and HMRC standards.

Key responsibilities include

• Leading the design and development of software products within the BDApp portfolio.
• Ensuring operational stability and performance of existing applications.
• Implementing changes to maintain compliance and improve efficiency.
• Working with stakeholders to deliver secure, effective and sustainable solutions.
• Supporting HMRC’s strategic direction by adopting cloud technologies and modern development practices.

This position requires a strong understanding of the software development lifecycle and HMRC’s IT infrastructure. It also involves applying knowledge of cloud platforms and enterprise architecture to deliver solutions that meet our organisational goals. The role combines technical leadership with hands-on development and collaboration across teams.

This is a challenging role for those looking to deliver technological change during a period of organisational transformation. It offers the opportunity to make a real difference to people’s lives by delivering high-quality digital products. As a Senior Developer, you will take responsibility for the operational stability of our portfolio of BDApps and ensure changes are implemented with ongoing robustness and reliability.

Person specification

As a Senior Developer you will take the technical direction and designs set by the Lead Developer and Technical Architect and turn them into well built secure and accessible software that meets HMRC standards. You will play a key role in delivery across the software development lifecycle by contributing high quality code and supporting the team to meet agreed outcomes. You will work closely with the Lead Developer to surface risks early and help keep delivery aligned to the agreed technical blueprint.

You will provide strong technical contribution by writing and reviewing high quality software, supporting less experienced developers through complex work, and applying consistent engineering practices. You will invest in your own learning and actively support the development of others. You will contribute to HMRC’s move from legacy systems to modern web, microservice and cloud based solutions. You will apply a solid understanding of Business Developed Applications and their place in HMRC’s technology landscape to help ensure solutions are stable, maintainable and aligned with organisational needs.

Key responsibilities

• Contribute to the design, development and delivery of BDApp products in line with the blueprint set by the Technical Architect and Lead Developer.
• Deliver hands on development and ensure solutions meet security, accessibility and coding standards.
• Support day to day technical delivery within the team and demonstrate effective leadership behaviours through example.
• Work with the Lead Developer to clarify scope, highlight risks and maintain a sustainable delivery pace.
• Support and mentor developers to build capability and confidence in line with Developing Self and Others.
• Identify technical risks or deviations from design principles and raise them early.
• Produce clear technical documentation and support teams to resolve complex issues.

Illustrative technical skills

• Strong experience of delivering software across the full software development lifecycle.
• Proficient in C# or another high level programming language.
• Experience of web, API, microservice or cloud based development.
• Understanding of Business Developed Applications and how they fit within HMRC’s technology stack.
• Ability to design, maintain and execute test scripts and support technical and user acceptance testing.
• Experience of modern development tooling including automation, robotics or low or no code where appropriate.
• Ability to produce clear technical documentation and support the transition of products into live operations.

Essential Criteria

• Strong experience in C# and .NET development,  including WPF, HTML, CSS.  Experience with low-code solutions is beneficial.
• Strong understanding of SOLID principles, test-driven development and design patterns such as MVVM and MVC.
• Experience with Entity Framework or other ORM tools, SQL or NoSQL databases, and relational database architecture including integrity constraints.
• Good knowledge of web technologies and protocols, including microservice architecture, APIs and containerised solutions.
• Awareness of software accessibility challenges and how to address them.
• Ability to communicate system changes, issues and risks effectively to project leads and stakeholders.
• Proven ability to work independently and as part of a team, demonstrating excellent organisational and interpersonal skills.
• Experience of sharing knowledge and best practice and critically evaluating own and others’ work to successfully implement software development best practices.

Desirable Criteria 

• Experience of mentoring and technically leading a team in an Agile environment.
• In-depth knowledge of exploiting an AWS platform.
