Job Description
As Lead Developer in HMRC, you will be responsible for setting technical direction, and ensuring the delivery of high-quality, scalable, and secure services.
You will guide and support a fast paced engineering team across the full service lifecycle, translating business and user needs into coherent technical designs, acting as an application architect, balancing strategic alignment with practical delivery, and remaining sufficiently hands-on to validate designs through prototypes or reference implementations.
You will lead low level solution design of complex large scale services and create corresponding documents and architectural diagrams. You must be proficient in a wide range of technical systems, and in identifying appropriate technology and approaches.
Alongside functional change, you would lead solution design to meet non-functional requirements such as resilience, performance, scalability and observability.
You will lead delivery of high quality software that meets user needs, and be responsible for overseeing the development of clean, secure code following a test-driven approach.
Key Responsibilities
- Set technical strategy and direction, ensuring architectural decisions, tooling choices and design approaches support scalable, secure, high-quality services.
- Provide expert judgement and act as the escalation point for complex or high-risk technical issues, guiding teams towards robust solutions.
- Act as a design authority for technical change to the service, ensuring all implementations align to HMRC Enterprise Architecture Patterns.
- Oversee the full lifecycle of build/run/improve, ensuring services remain resilient, compliant and aligned to user and business needs, even when not personally hands-on.
- Provide leadership to developers, delegating technical work, supporting planning, reviewing solution approaches, and ensuring development is on track and to the expected quality.
- Assure security compliance, embedding secure-by-design principles and ensuring risks are understood and mitigated.
- Lead on solution design & technical decision-making, including reviewing and challenging design choices (e.g., Redis persistence strategies, interface behaviours, microservice consolidation).
- Ensures compliance with performance and design standards, influencing cross-team technology choices (e.g., SSO, Keycloak, REST template decisions).
- Contribute to the development of robust, accurately estimated, project plans, considering risk and mitigation.
- Critical decision making: Making and recording effective decisions following the appropriate decision-making criteria, framework or guidance.
