Reporting to the CTO, as a Full Stack Developer you will work across the full platform — a modular monolith built in .NET 10 on the backend and React on the frontend. You will own features from requirement to production, working in a small, high-trust team where your decisions have direct product impact.

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

- Implement message-based integrations over RabbitMQ and HTTP, with proper retry, dead-letter, and observability patterns

- 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 , , and 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 security and size best practices

- Deploy and manage workloads on Kubernetes clusters — writing and reviewing manifests, Helm charts, and managing config/secrets

- Collaborate with DevOps on CI/CD pipelines, environment configuration, and production readiness

- Participate in on-call rotation for production incidents (light, given our scale).

What We’re Looking For
Must-have

-

- 4+ years of professional .NET development (C#), with strong understanding of clean architecture and SOLID principles

- Solid React and TypeScript experience — you write components that are readable, testable, and maintainable

- Genuine TDD discipline — you write tests before or alongside code, not as an afterthought; you understand the difference between unit, integration, and end-to-end tests

- Hands-on experience with RabbitMQ or similar message brokers in production systems





- PostgreSQL proficiency — schema design, migrations, query analysis, and indexing

- Practical Kubernetes experience — you can read and write manifests, understand pod scheduling, and debug deployment issues

- Docker fluency — you build lean, layered images and understand multi-stage builds

- Experience working in or contributing to a modular monolith or DDD-influenced codebase

- Strong English communication skills — written and verbal

Strong advantage

-

- Experience using Claude Code, GitHub Copilot, or similar AI coding assistants as a genuine productivity tool in a professional codebase

- Familiarity with structuring AI context files ( -style) to guide code generation effectively

- Experience with GCP (Cloud Run, Cloud Storage, Pub/Sub, Vertex AI)

- Playwright or similar e2e test framework experience

- Exposure to knowledge graphs, Neo4j, or graph-based data modelling

Our Engineering Ethos

-

- Test coverage is a delivery requirement, not a nice-to-have. Core business logic ships with tests.

- PR reviews are substantive. We comment on architecture, not just typos.

- We use AI tooling to move faster, not to lower the quality bar. AI-generated code gets reviewed like any other code.

- We document decisions. ADRs, Notion pages, and Claude Code context files are part of the job.

- We raise issues early. A blocker surfaced on day one beats a missed deadline on day ten.

-

- Control Risks offers a competitively positioned compensation and benefits package that is transparent and summarised in the full job
