We are looking for an experienced Full Stack Developer to join a greenfield project within DNA Data and Navy Applications.

Working alongside the technical lead and the wider team, you will help build a new TypeScript codebase from the first commit, contributing end to end across the service layer and the front-end interfaces on top, deployed to containerised infrastructure. You will work with a good deal of independence, and contribute to the engineering standards and architectural decisions the team settles on.

Requirements

- Build out features end to end.

- Integrate with existing services, message queues and databases.

- Work with product designers to turn designs into responsive, accessible (WCAG 2.2 AA) interfaces.

- Design and optimise PostgreSQL schemas and queries.

- Write unit, integration and end-to-end tests, and review other developers' code.

- Own your code through to production: CI/CD pipelines, containerised deployment, and diagnosing issues in running environments.

- Keep dependencies and container images patched, and address security findings as they arise.

- Contribute to technical direction, tooling and standards.

- Take part in Agile ceremonies and technical scoping sessions.

SFIA Level 5

Must haves:

● 5+ years of professional software development experience, with a track record of delivering features independently.

● Strong TypeScript on both front-end and back-end.

● React, modern CSS, and experience building to WCAG 2.2 AA.

● https://jobeax.com/link/JSd7UYCSg572jJDY, building and consuming REST APIs.

● PostgreSQL: schema design, query optimisation, and use of an ORM.

● Unit, integration and end-to-end testing.

● Git, and practical experience of CI/CD pipelines (GitHub Actions preferred).

● Docker, and comfort working with containerised applications.

● Authentication and authorisation using OIDC (e.g. Keycloak).

● Experience working within Agile software delivery.

● Able to explain technical decisions to non-technical stakeholders.

Nice to haves:

● Experience within MOD/Defence or another regulated environment.

● Kubernetes or OpenShift, enough to deploy and debug your own services.

● Infrastructure as code (Helm, Terraform).

● Observability tooling (Grafana, Prometheus, Loki).

● Exposure to other programming languages and stacks.
