Role Summary 

We are building one of Europe’s largest AI infrastructure offering that will provide our customers a private and integrated stack in every form factor they may need — from bare-metal servers to fully-managed PaaS. As a DevOps Engineer, you will join a fast growing team to help building, scaling and automating our computing management stack. You will be responsible for building fault-tolerant and reliable infrastructure to support both our internal processes and customer platform.

Location: France 🇫🇷 and UK 🇬🇧 as primary location, or remote under conditions (see below)

Reporting line: Software Architect, HPC

What you will do

As a DevOps Engineer in the HPC services team, your primary responsibility will be to engineer robust and dependable infrastructure that supports both our internal operations and customer-facing platforms.

Key Responsibilities:

• Design, build and maintain scalable, highly available and fault-tolerant infrastructures

• Build, scale and automate the full lifecycle of compute nodes, from bootstrapping to decommissioning

• Design and develop new workflows and tooling to improve to the reliability, availability and performance of our systems (automation scripts, API-based features, web apps, dashboards, etc.)

• Drive continuous improvement in infrastructure automation, deployment, and orchestration (CI/CD, containerization, orchestration, monitoring, logging and alerting systems...)

• Operate systems and troubleshoot issues in production environments (interrupts, on-call responses, users admin, data extraction, infrastructure scaling, etc.)

• Participate occasionally in on-call rotations to respond to incidents and perform root cause analysis to prevent future occurrences

• Collaborate closely with R&D to streamline build systems, scale testing workflows and make sure our inference and model training environments are always highly available and seamlessly replicable across several HPC clusters

• Collaborate with the security team to ensure infrastructure adheres to best security practices and compliance requirements

About you

• 7+ years of experience in a DevOps/SRE role

• Exposure to highly available distributed systems and site reliability issues in critical environments (issue root cause analysis, in-production troubleshooting, on-call rotations...)

• Proficiency in scripting languages (Python, Go, Bash...) and knowledge of software development best practices

• Hands-on experience with CI/CD, containerization and orchestration tools (Docker, Kubernetes..)

• Proven experience troubleshooting complex K8s cluster issues and performing system upgrades

• Familiarity with infrastructure-as-code tools like Terraform or CloudFormation

• Knowledge of monitoring, logging, alerting and observability tools (Prometheus, Grafana, ELK Stack, Datadog...)

• Experience working against reliability KPIs (observability, alerting, SLAs)

• Strong understanding of networking, security, and system administration concepts

• Excellent problem-solving and communication skills

• Self-motivated and able to work well in a fast-paced startup environment

Now, it would be ideal if you also had experience with:

• HPC workload managers (Slurm)

• Distributed storage systems (Lustre, Ceph)

Location & Remote

This role is primarily based at our HQ in Paris, France. We will prioritize candidates who either reside in Paris or are open to relocating. We strongly believe in the value of in-person collaboration to foster strong relationships and seamless communication within our team. Our remote work policy is designed to offer flexibility, enhance work-life balance, and boost productivity. The number of remote workdays is determined by each manager, taking into account individual autonomy and specific circumstances—such as increased flexibility during the summer months. Regardless of the arrangement, we expect all employees to maintain open lines of communication with their teams and be available during core working hours.

In certain specific situations, we will also consider remote candidates based in one of the countries listed in this job posting (currently France, UK, Germany, Netherlands, Spain and Italy). In that case, we ask all new hires to visit our Paris office:

•  for the first month of their onboarding (accommodation and travelling covered)

•  then at least 3 days per month
