Site Reliability Engineer -Openstack (m/f/d)

At our company, it’s all about #OneTeam! Join gridscale and help shape the future of the cloud together with OVH. As a leading tech company, we’ve been working for over two decades to reduce our environmental footprint - with innovative solutions and an open cloud designed to be sustainable from the ground up: #SustainableByDesign. Our Tech Stack 🚀 · OpenStack · Kubernetes · KVM · Linux · Bare Metal · Ansible · Terraform · Go · FluxCD / ArgoCD · Git· Python · Claude Code · Cursor · Agentic Coding Tooling Your Role You will help us build, operate and industrialize OVHcloud's on-premise cloud platform. As part of a small, senior team, you will work on our OpenStack-based infrastructure and the Kubernetes / GitOps stack powering our customer-facing cloud. AI-assisted engineering is a first-class part of how we work – from spec-driven development and agentic coding workflows to incident response and automation. The platform is in active development, giving you real influence on the architecture, automation strategy and how we adopt AI in platform engineering. As a Senior Engineer, you take ownership of your area and shape your focus based on your strengths, with a clear backbone of automation, compute lifecycle, platform engineering and AI substrate work. Your Responsibilities • Design and build our OpenStack-based on-premise cloud infrastructure, with the goal of bringing complete cloud environments from bare metal to production through a highly automated deployment process. • Develop and operate Infrastructure as Code with Ansible and Terraform as well as our Kubernetes and GitOps workflows using FluxCD / ArgoCD, supported by LLMs, agentic workflows and automated testing and review. • Own the lifecycle of our compute infrastructure – from bare metal, firmware and provisioning through to hypervisors and virtual compute nodes. This includes patching, migrations, host evacuation, capacity rebalancing and the automation required to keep the platform healthy. • Build and extend our AI substrate and self-healing capabilities, from structured knowledge bases and agentic workflows for incident triage and capacity planning to gradually turning today's manual runbooks into automated processes. • Design tests for non-regression, performance and security, document and package solutions, and continuously improve the platform based on telemetry, operational experience and user feedback. • Act as a technical reference and sparring partner for peers across automation, platform engineering and AI tooling. What we offer you • A platform genuinely in build mode, with real room to shape architectural decisions, strong ownership and a senior team where autonomy matters. • AI-augmented engineering as a first-class workflow - including Claude Code and comparable agentic tooling, Markdown-based knowledge bases and room to push our engineering practices further. • Exceptional team spirit across all departments and national borders; we live #OneTeam. • Exciting work in a highly innovative and international environment with cutting-edge technologies. • 32 vacation days, increasing with length of service. • Flexible working hours, home office options, and a secure permanent position with market- and performance-based compensation. • Employer-funded pension plan and an attractive insurance package. • OVHcloud covers 50% of public transportation costs. • Up to €400 annual financial contribution from OVHcloud towards sports activities, such as gym memberships or sports classes. • Through Corporate Benefits, you receive attractive discounts at numerous shops and companies. • We contribute to the leasing of your cargo bike. • Regular company events and free cold and hot beverages. • Several years of hands-on experience as an SRE, Platform Engineer or DevOps Engineer running production infrastructure, with strong experience in OpenStack, Kubernetes and Linux, including bare metal. • You have managed compute infrastructure end-to-end, from firmware / BIOS rollouts, bare-metal provisioning and hardware diagnostics to hypervisors, migrations, host evacuation, graceful drains and capacity rebalancing. • AI-assisted engineering is already part of your daily work. You use LLMs and agentic tools where they meaningfully support development, testing, reviews, or operations, and you know where AI adds real value and where strong engineering expertise remains essential. • You are confident working with Ansible, Terraform and GitOps workflows such as FluxCD or ArgoCD and understand what it takes to turn automation into robust, repeatable production systems. • Ideally, you write Go and/or Python and have experience with Claude Code, Cursor, Aider or comparable agentic coding environments. Exposure to observability, networking, compute tuning, auto-remediation, security-critical infrastructure or multi-site clouds is also a plus. • You work autonomously, bring a strong sense of ownership and enjoy improving systems rather than simply keeping them running. You also enjoy sharing knowledge and can communicate complex technical topics clearly. • You are fluent in English, written and spoken. English is the working language of our distributed team.
