DevOps, Core Platform

Paris. Posted 3 days ago

The role

You will own the continuous deployment of software in customer data centers and on hardware, often with no internet connection. This role involves hands-on coding to manage installations, upgrades with no downtime, and service dependencies.

What you will do

Take a change from a commit in CI to a running system on a customer site and keep every step repeatable.
Roll out upgrades step by step with no downtime.
Make installs and upgrades work with no internet using signed, self-contained packages.
Work on the release system that checks that all services work together.
Work with platform architects and developers so every new service is easy to package, deploy and upgrade.
Work with forward deployed engineers so the same tools run in development and at the customer.
Write the procedures that a person at a customer site can follow without help.
Make it easier and faster for engineers to ship changes to customer sites.

Required qualifications

Several years of backend or infrastructure engineering, ideally on a product with many services and many deployments.
Strong skills in at least one language (Rust, Go, Python, Java).
Hands-on experience with Kubernetes and containers, and with Helm, GitOps (Argo CD or Flux) and CI systems.
Built, not just used, tools that deploy or run software.
Run or debugged upgrades or deployments in production.
Know the basics of metrics, health checks and logs.
Degree in computer science, software engineering or a similar field or equivalent professional experience.
Clear written and spoken English.

Nice to have

Writing Kubernetes operators or controllers.
Signing and supply-chain tools, such as Sigstore/cosign and SBOMs.
Packaging software for air-gapped sites, for example with Zarf and registry mirrors such as Harbor.
Bare-metal Kubernetes (OpenShift, RKE2 or Talos) with Ceph or MinIO.
