Overview
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.
Responsibilities
* 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 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
* Deep GitHub Actions expertise (reusable workflows, composite actions, OIDC)
* Strong build tooling: .NET CLI / MSBuild and/or Maven / Gradle
* This is engineering, not pipeline admin
* 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
* Hybrid cloud and on‑prem infrastructure experience
* Strong CI/CD and build systems background
* Experience owning real systems in production
Qualifications
* Hybrid Cloud + On‑Prem Infrastructure
* Experience owning real systems in production
* Strong CI/CD and build tooling depth
* VMware vSphere / Hyper‑V
* Deep GitHub Actions expertise (reusable workflows, composite actions, OIDC)
* Strong build tooling: .NET CLI / MSBuild and/or Maven / Gradle
Fit and expectations
* Less Likely a Fit If Your Background Is:
* Kubernetes or orchestration‑heavy
* Cloud‑only in recent years
* 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.
