Description:
Rubicon Consulting is currently recruiting for X4 Software Engineer (DV Cleared) on a 6 Month Contract, based in London.
Role Summary
We're recruiting for a specialist security team working on critical national infrastructure projects — high-impact, high-visibility work protecting UK organisations from cyber threats at scale.
This role requires DV (Developed Vetting) clearance — either currently held, or you meet the eligibility criteria (typically British citizen, 10 years continuous UK residency). Please only apply if this applies to you.
The role
You'll join a software-defined, automation-first engineering environment building and running CI/CD platforms with security embedded from day one — not bolted on afterwards. Think fast iteration, Infrastructure-as-Code as the default, and end-to-end ownership from build through to production.
What you'll be doing
* Owning and delivering platform capabilities across a highly-automated, CI/CD-driven environment
* Designing and evolving CI/CD pipelines for reliable, repeatable delivery across multiple teams
* Embedding Infrastructure-as-Code, eliminating manual provisioning and config drift
* Integrating security controls into engineering workflows — secure by design, not by afterthought
* Supporting engineering teams with tooling, guidance and best practice
* Driving adoption of modern engineering practices — CI, CD, automated testing, observability
* Contributing to technical standards and governance across teams
* Supporting incident response and continuous improvement through retrospectives
Requirements
Not every box needs ticking, but strength across most of the following:
* CI/CD platforms — GitLab, Jenkins
* Infrastructure-as-Code — Terraform, Ansible, Chef or Puppet
* Containerisation — Kubernetes, Helm
* Cloud-native platforms — AWS, Azure, GCP or VCF
* Release automation — ArgoCD, Flux
* Observability — Prometheus, Grafana, ELK
* IAM & secrets management — OAuth/OIDC, Keycloak, Vault
* Software development — Java, Python, JavaScript, C++ or C#
* Solid grounding in security principles — CIA, Least Privilege, Zero Trust
* Networking fundamentals — DNS, TCP/UDP, firewalls, VPNs
