New Job Opening: Fullstack Software Engineer- Multiple Opportunites in Romsey, UK

Job Description

Full Stack Software Engineer

Location: Gloucestershire, Woking and Romsey

Hybrid: Hybrid working across secure sites and collaborative engineering environments

Salary: Competitive salary aligned to experience and clearance level

Clearance: Active UK*C DV clearance required 

The Opportunity

This is the kind of environment that tends to attract engineers who want to stay close to meaningful technical work without becoming constrained by heavily layered delivery structures or narrow ownership boundaries.

The work sits across the UK National Security and Intelligence ecosystem, supporting operational systems used within highly secure, high-side environments where reliability, adaptability and engineering quality matter. Programmes are long-term and mission-focused, but teams still retain the flexibility and engineering autonomy typically associated with smaller, engineering-led organisations.

What often appeals to experienced engineers is the level of exposure. Rather than being isolated to a single layer of the stack or a tightly defined delivery function, engineers here tend to work closely with users, technical leadership and multidisciplinary teams across the wider software lifecycle. There is genuine opportunity to influence how systems evolve, contribute ideas early and build a broader understanding of operational capability.

The culture is collaborative, low-ego and technically grounded. Teams value pragmatic engineering, modern software practices and people who are comfortable solving problems collectively rather than simply delivering against tickets. For engineers who enjoy ownership, project variety and working across all compass points of secure delivery, it is the kind of environment that can offer strong long-term development without losing technical depth.

The Role

You’ll be joining an agile engineering team responsible for designing, building and improving secure software systems used within operational National Security environments.

The role combines hands-on full stack engineering with close collaboration across users, engineers and stakeholders, making it well suited to somebody who enjoys solving technical problems while understanding the wider operational context behind the systems they are building.

Teams work iteratively and collaboratively, with engineers contributing throughout the delivery lifecycle from early design discussions through to implementation, testing and ongoing improvement of live capability.

• Developing secure, maintainable software using Java and Spring Boot across scalable backend services and APIs.


• Building frontend functionality using modern JavaScript frameworks such as React, Vue.js or Angular.


• Supporting API integration, data ingestion pipelines and backend services used within secure operational systems.


•  Writing tested, reliable code using modern engineering approaches including TDD and automated testing frameworks.


• Translating technical designs and logical system requirements into working software solutions within agile delivery teams.


• Contributing to the evolution of existing architecture, RESTful services and scalable platform components.


• Collaborating with engineers, user researchers and stakeholders to better understand operational challenges and user requirements.


• Participating in agile ceremonies, including planning, refinement sessions, retrospectives and technical discussions across multidisciplinary teams

The team is less interested in rigid checklist matching and more focused on adaptable engineers who enjoy learning, collaborating and contributing across the wider engineering lifecycle.

Strong communicators tend to do well here because engineers are trusted with visibility, ownership and influence. It suits people who enjoy understanding user problems, contributing to technical direction and working in environments where engineering quality carries genuine weight.

Security Requirements

Due to the nature of the work, active eDV/ UK*C DV clearance is required.
