DNA drives the Royal Navy’s capability by delivering digital solutions that increase operational efficiency, effectiveness, and availability. Operating across Official and Secret domains, from shore to sea. DNA provides end-to-end support for bespoke and procured applications.
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
- Node.js, 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
