**Are you a software engineer who wants your work to genuinely matter?**

We're looking for a passionate software engineer to join a high-performing team tackling some of the most technically demanding challenges in the defence sector.

This isn't about maintaining legacy systems or shipping incremental updates - it's about building cutting-edge capability that operates at the edge, in the field, and under pressure.

## The Role

You'll be part of a team delivering software solutions that leverage the latest in machine learning, edge compute, and DevOps automation.

Think rapid capability deployment, deployed hardware environments, sensors, and robotics - the kind of engineering problems that push you to grow.

You'll own code releases and deployments, support operational systems, and collaborate across disciplines to drive agile best practice into real-world solutions.

## What You'll Be Doing

You'll work closely with product owners and fellow engineers across the full delivery lifecycle - from architecture discussions to production deployments. Day to day, that means contributing to agile ceremonies (Scrum, Kanban or SAFe), participating in code reviews, working with quality engineers to uphold high standards, and troubleshooting operational systems when it counts.

This is a collaborative, technically ambitious environment where your voice matters and your ideas get heard.

## What We're Looking For

You'll have a degree in a STEM subject, or equivalent practical experience. Beyond that, we're interested in engineers who are curious, proactive, and genuinely energised by solving hard problems.

You'll be familiar with some combination of the following - we don't expect expertise across everything, but we do want depth in some areas and a hunger to learn the rest.

**Languages:** Python, Java, Rust, or JavaScript

**Cloud:** AWS (primary), with Azure or GCP experience a bonus

**Containerisation & Virtualisation:** Docker or Podman, Kubernetes, and ideally some exposure to GPU containerisation (NVIDIA Container Toolkit, Run:AI)

**Architecture:** Microservices, serverless, edge compute, RESTful APIs, Protobuf/gRPC, and stream-based pub/sub systems including Kafka and MQTT

**DevSecOps:** Git, CI/CD pipelines (e.g. GitLab), Infrastructure as Code (Terraform, Puppet, Ansible), and Linux shell scripting

As important as the technical profile is the person behind it. You'll communicate clearly with colleagues at all levels, thrive in a team, and take ownership of your work with a solutions-first mindset.

## What's on Offer

Alongside a competitive salary, you'll have access to a flexible benefits package spanning health and wellbeing, financial protection, and lifestyle perks.

You'll join a genuinely inclusive organisation that invests in its people and its technology in equal measure - having doubled in size over the last four years, the growth here is real and the opportunities that come with it are too.

There's also a thriving internal community of technical groups where engineers come together around shared interests, tools, and ideas. It's the kind of place where intellectual curiosity is encouraged, not just tolerated.

**This role requires the ability to obtain UK Security Clearance.**

If you're ready to work on problems that matter, with people who take pride in what they build, we'd love to hear from you.
