Job Description

We're looking for a Software Engineer to join a growing team delivering innovative software solutions to some of the UK's most complex technical challenges.

Working across cloud, edge computing, AI and modern software engineering, you'll help design, build and deploy secure, scalable applications that make a genuine difference. You'll work alongside talented engineers in a collaborative environment where you'll be encouraged to learn, innovate and shape the way solutions are delivered.

The Role

As a Software Engineer, you'll be involved throughout the software development life cycle, from designing and building applications through to deployment and ongoing support. You'll work within Agile teams, contribute to technical decisions and help deliver high-quality software using modern engineering practices.

You'll also have the opportunity to broaden your experience across areas such as cloud technologies, automation, sensors and emerging technologies.

What You'll Be Doing

  • Designing, developing and maintaining software solutions
  • Working closely with engineers, architects and product teams to deliver high-quality products
  • Participating in Agile ceremonies including Sprint Planning, Reviews and Retrospectives
  • Contributing to code reviews and engineering best practice
  • Supporting deployments and resolving issues in live environments
  • Continuously improving processes, tooling and software quality

What We're Looking For

You'll have a degree in a STEM subject (or equivalent industry experience) and experience with some of the following technologies:

Programming Languages

  • Python
  • Java
  • Rust
  • JavaScript

Cloud & Infrastructure

  • AWS (preferred)
  • Azure or GCP
  • Docker or Podman
  • Kubernetes

Software Engineering

  • Microservices

  • Event-driven systems (Kafka, MQTT)

DevSecOps

  • Git
  • CI/CD (GitLab or similar)
  • Infrastructure as Code (Terraform, Ansible or Puppet)
  • Linux and Shell Scripting

Just as importantly, you'll be someone who enjoys solving problems, works well as part of a team and is always looking for better ways of doing things.

What's On Offer

  • Competitive salary
  • Flexible benefits package covering health, wellbeing, lifestyle and financial benefits
  • Ongoing learning and professional development
  • Collaborative and supportive engineering culture
  • Opportunity to work with modern technologies on meaningful projects
  • Inclusive working environment where everyone is encouraged to contribute and grow
