You will be responsible for building fault-tolerant and reliable infrastructure to support both our internal processes and customer platform.

Location: France and UK

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)
