About the Job

As a Lead Software Developer, you will work on the following:

• Back-End Application Development and Service Ownership: Build, develop, and maintain protected, adaptable, and resilient back-end services using Python frameworks (e.g., Flask), Azure cloud services, and related technologies. Ensure applications and services operate optimally in production, proactively monitor performance, respond to issues, and continuously improve service quality and availability.
• Own the creation and development of accessible, intuitive, and user-focused front-end applications that fulfil user needs. Use Python-based front-end frameworks like Plotly Dash and JavaScript frameworks such as React when suitable.
• Solution Architecture and Systems Integration: Build and ensure scalable software architectures that fulfil business and user requirements. Assess and choose suitable technologies, architectural patterns, and development methods, guaranteeing smooth integration among applications, data platforms, APIs, and enterprise services within HM Treasury and, when necessary, the broader government.
• User Engagement and Agile Product Development: Engage extensively with users throughout the software development lifecycle, conducting discovery activities, capturing requirements, validating assumptions, and facilitating testing. Apply user-centred development principles to ensure products are driven by user needs and deliver measurable value to the organisation.
• Technical Leadership and Delivery: Deliver technical direction across software development initiatives, ensuring technical quality is upheld during the entire software lifecycle. Support development teams in embracing up-to-date engineering approaches, handle technical risks and dependencies, and facilitate successful delivery by applying agile and iterative processes.
• Security, Standards and Engineering Excellence: Ensure that software, services, and platforms are built with appropriate security controls, operational monitoring, and governance from the beginning.
• Innovation and New Technologies: Find chances to use innovative technologies, including generative AI and other new tools, to improve business processes and enhance user experiences. Work to increase interpersonal efficiency. Support the safe, responsible, and efficient introduction of new technologies throughout HM Treasury.
• Software Development Champion: Support the growth of engineering skills throughout the team and organisation, and promote the use of effective software engineering methods.
