Key Responsibilities

1. Technical design

   • Owns the technical design for the squad's stories, produced in the Sprint preceding build: API contracts, data model changes, component structure and integration approach.
   • Takes the design to the Solution Architect for endorsement before build is authorised.
   • Escalates to the Solution Architect where a story implies an architecture or data model change, rather than resolving it locally.
   • Attends the design walkthrough with the Business Analysts and raises what the functional design has not resolved.

2. Delivery

   • Plans the squad's build work for the Sprint and owns its delivery against the Sprint commitment.
   • Implements stories to Definition of Done, and writes the unit and integration tests for their own code.

5. AI-assisted development

   • Reviews generated code before it is committed and is accountable for it as their own.

Experience and Qualifications

• 4-7 years in software engineering on enterprise Java with a modern front end.
• At least 2 of those years on an agile delivery working to a Sprint cadence, building from user stories rather than specifications.
• Has built and deployed on Government Commercial Cloud (GCC), working to the GCC landing zone and its account separation.
