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.

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.

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.

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.
