What You’ll Work On

Backend (.NET / Modular Monolith)
• Build and extend modules within a clean modular monolith architecture — Domain, Application, Infrastructure, and API layers per module

• Design and own PostgreSQL schemas, migrations (Liquibase), and query optimisation for compliance-grade data integrity
• Write code test-first — unit tests, integration tests with in-memory and real DB where appropriate, and end-to-end API tests
• Contribute to and enforce coding standards, PR reviews, and architectural decisions.

Frontend (React / TypeScript)
• Build complex,



accessible UI components and multi-path forms for compliance workflows
• Maintain consistency with our design system and work closely with our UX designer on new feature implementation
• Integrate with the backend via typed API contracts, handling loading states, error boundaries, and optimistic updates correctly

AI-Augmented Development
• Use Claude Code as an active development tool — you will work with CLAUDE.md, SKILLS.md, and RULES.md context files to give the AI accurate codebase context
• Translate Jira requirements and Notion design documents into structured Claude Code prompts that produce high-quality, testable code
• Maintain and improve the Claude Code context layer as the codebase evolves, treating it as first-class documentation
• Evaluate AI-generated code with the same rigour as human-written code — you own the output

Platform & Deployment
• Build and maintain Docker images for all services, following secu
