Lead DevSecOps Engineer
London | Hybrid | Competitive Salary + Equity
A well-funded, fast-growing technology company is building critical software and infrastructure for the next generation of autonomous and data-driven systems.
They are looking for a Lead DevSecOps Engineer to take ownership of their internal developer platform and build the infrastructure, tooling, and engineering practices that allow teams to ship secure, reliable software at pace.
This is a highly autonomous role where you'll treat infrastructure as a product. You'll work closely with engineering teams to remove friction from the development lifecycle, standardise deployment patterns, and build a robust "Golden Path" from local development through to production.
What you'll be doing
- Own and evolve the internal developer platform and overall Developer Experience.
- Design secure, automated, and repeatable deployment patterns across environments.
- Drive modern CI/CD and GitOps practices across the engineering organization.
- Build and maintain infrastructure across cloud and hybrid environments.
- Manage containerised workloads and orchestration at scale.
- Develop Infrastructure as Code using tools such as Terraform, OpenTofu, or Pulumi.
- Build automation and internal tooling using Python, Go, or Bash.
- Improve platform security through automated policy enforcement and compliance-as-code.
- Build standardised observability and telemetry across the platform.
- Own and improve critical engineering tooling and infrastructure.
- Help migrate and evolve platforms with minimal disruption and strong data integrity.
- Work closely with software engineers to make infrastructure simpler, safer, and more self-service.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What they're looking for
- 3+ years' experience building or scaling developer platforms, DevOps infrastructure, or sophisticated CI/CD environments.
- Strong understanding of cloud-native infrastructure across compute, networking, and storage.
- Experience with Kubernetes or similar container orchestration platforms.
- Strong Infrastructure as Code experience, ideally with Terraform, OpenTofu, or Pulumi.
- Strong scripting or systems programming skills in Python, Go, or Bash.
- A genuine software engineering mindset — you're comfortable building tools and platforms, not just maintaining infrastructure.
- Experience embedding security, observability, and reliability into developer workflows.
Bonus points for
- GitLab, Artifactory, SonarQube, or other self-hosted engineering platforms.
- GitOps and tools such as ArgoCD.
- OpenTelemetry, Prometheus, ELK, or similar observability tooling.
- OPA, Kyverno, AWS Config, or other policy/compliance tooling.
- Service mesh technologies such as Istio or Linkerd.
- Experience working across hybrid or highly secure environments.
- Experience with classified or sensitive networks.
- FinOps, cost attribution, or automated infrastructure optimisation.
- Go, Python, or Rust development for internal tooling, controllers, or APIs.
