Senior Software Developer (Remote – UK Based)

Full-time | Start: ASAP |

Active SC clearance required (can start with BPSS while SC transfers)

The client seeks a Senior Software Developer to join an existing multidisciplinary project team delivering a high-impact digital service for the healthcare sector. This role is fully remote from anywhere within the UK, with only very occasional travel.

A third Senior Software Developer is being added to this workstream due to increased demand. The role requires someone comfortable working across backend, frontend, automated testing, CI/CD, and infrastructure components, with excellent communication skills and the ability to contribute across the full engineering lifecycle.

Key Responsibilities

Software Development

• Implement end-to-end service journeys that meet design specifications, align with best practice, and satisfy business requirements.
• Build, test, and deploy production-ready features using Express.js, TypeScript, and MOJ Design System components.
• Integrate with existing and newly created Kotlin APIs following approved patterns and guidelines.
• Deliver features that meet user stories, acceptance criteria, and client standards.
• Ensure code passes automated tests and deploys successfully through CI/CD pipelines.
• Develop and maintain infrastructure-as-code for multiple environments using Terraform.
• Enable successful, repeatable deployments to AWS.

Quality Assurance

• Produce clean, maintainable, well-documented code aligned with secure-by-design principles.
• Apply Test-Driven Development (TDD) and maintain strong automated test coverage.
• Participate in rigorous code reviews and uphold engineering best practices.
• Identify and proactively address security vulnerabilities.
• Challenge constructively and recommend improvements to processes or implementation approaches.

Knowledge Transfer

• Provide clear documentation for processes, decisions, and solutions.
• Deliver handover materials and walkthroughs as required.
• Ensure knowledge transfer is accepted by both the customer and the client.

Cloud & Infrastructure

• Writing Terraform-based infrastructure as code
• Managing CI/CD pipelines, preferably with GitHub Actions
• Experience with Docker and Kubernetes

Engineering Practices

• Strong commitment to TDD, automation, and clean engineering standards
• Comfortable with pair programming, peer reviews, and knowledge sharing
• Experience working in agile, multidisciplinary teams

Role Focus

This role is not primarily feature-driven. Instead, it emphasises:

• Addressing accumulated technical debt
• Developing automated UI and API tests
• Implementing internal support tools to help manage support traffic
• Investigating and aligning with existing client test frameworks

Security Requirements

• Active SC clearance required
• Can start with BPSS while SC is transferred

The developer will join a major ongoing project for the healthcare sector, established earlier in 2025, providing additional capability to support increased workload and deliver a robust, scalable digital service.
