Full Stack Software Engineer Full Time

National Security Projects | London & South-East | Up to £80,000 DOE + Benefits

Are you ready to make a real impact? Join a highly trusted and growing team delivering mission-critical technology into the National Security space. This is your chance to work on projects that matter — protecting people, platforms, and data in an ever-evolving digital landscape.

This isn’t your average software engineering role. If you’re looking to build another app that speeds up transactions, this isn’t for you. But if you’re excited by the idea of shaping the future of secure platforms — using AI, cloud, big data, DevOps, and cutting-edge software development — then keep reading.

The Opportunity
As a Full Stack Software Engineer, you’ll be part of a multidisciplinary team delivering novel, high-assurance software products to National Security customers. You’ll get hands-on with leading-edge technologies and enjoy the variety of building products from scratch, integrating complex systems, and consulting directly with end users.

You’ll also work closely with experts in AI/ML, cloud infrastructure, and cyber security, so it’s a great place to expand your skillset and stay at the forefront of tech in a secure, purpose-driven environment.

What You’ll Be Doing

• Writing clean, secure code using a test-driven approach
• Translating logical designs into well-structured, scalable software
• Building APIs, user interfaces, and backend services
• Developing and maintaining components such as data pipelines, data stores, and RESTful APIs
• Collaborating with user researchers to understand real user needs
• Participating in agile ceremonies and working with product owners, testers, and researchers

What We’re Looking For
You don’t need to tick every box, but experience with some of the following will help:

• Programming: Python, Java, JavaScript, Golang, or C++
• Frameworks: React, AngularJS, or Vue.js
• Web technologies: Node.js, Nginx, Caddy, Uvicorn
• Databases: PostgreSQL, MySQL, MongoDB, Cassandra
• Containerisation: Docker, Podman, Kubernetes
• Cloud: AWS, Azure, GCP
• Scripting: Bash, PowerShell
• A fast learner – able to pick up new tools and technologies quickly as needed

Why This Role?
You’ll be working on secure-by-design solutions that genuinely contribute to national safety and resilience. The role is based between modern offices in the South East and customer sites in London. Expect a mix of remote work, collaborative on-site sprints, and access to excellent R&D facilities.

Locations
There are two main office hubs in the South East – both offer free parking, great amenities, and easy access to London. You’ll also spend time on-site with clients in the London area.

Security Clearance
Due to the sensitive nature of the work, candidates must be eligible for DV clearance. This means you must be a British Citizen and have lived in the UK continuously for the past 10 years.
