Principal DevOps

🚨Principal DevOps Engineer | Docker‐First | Hybrid Cloud & On‐Prem

Our global payments client is hiring a Principal DevOps Engineer to build and own the delivery platforms behind a large‐scale, mission‐critical payments system.

This is a hands‐on, product‐led engineering role. Not consulting, not Kubernetes, and not cloud‐only.

You will be from a software engineering background with strong fundamentals (code quality, design patterns, testing), not purely ops profiles.

Key technical:

• Migrating to GitHub Enterprise / GitHub Actions — CI/CD expertise essential
• Core stack: Terraform + Ansible, HashiCorp Vault, Cloudsmith, Docker / Docker Compose, Cloudflare
• Polyglot estate — primarily .NET and Java
• Delivery to both cloud (AWS/Azure/GCP) and on-premise Linux environments
• No Kubernetes — Docker/Compose is the container sweet spot

🔑 What Makes This Role Different

✅Docker & Docker Compose — not Kubernetes

• Docker & Docker Compose are used in both development and production
• Multi‐stage builds, image optimisation, and advanced Compose patterns
• Kubernetes / Helm‐centric backgrounds are out of scope

✅Hybrid Cloud + On‐Prem Infrastructure

• Operates across cloud and on‐prem environments
• Strong focus on on‐prem workloads
• VMware vSphere / Hyper‐V
• Infrastructure as Code applied outside the cloud

✅Serious CI/CD Engineering

• Deep GitHub Actions expertise (reusable workflows, composite actions, OIDC)
• Strong build tooling: .NET CLI / MSBuild and/or Maven / Gradle
• Artifact promotion pipelines across multiple formats
• This is engineering, not pipeline admin

✅Product Engineering Mindset

• Build, own, and operate platforms in production
• Clear outcomes: built, owned, migrated, reduced X by Y%
• Consulting‐only backgrounds without product ownership are less suitable

✅ Strong Fit If You Have:

• Deep Docker & Docker Compose expertise
• Hybrid cloud and on‐prem infrastructure experience
• Strong CI/CD and build systems background
• Experience owning real systems in production

🚫 Less Likely a Fit If Your Background Is:

• Kubernetes or orchestration‐heavy
• Cloud‐only in recent years
• Primarily consulting‐led
• Light on CI/CD or build tooling depth

💡 If you prefer clarity over complexity, ownership over buzzwords, and enjoy building platforms that support real‐world payment traffic, this is a rare opportunity.
