Location: Remote - Europe
Reporting line: Team Lead, Site Reliability Engineer

What you will do

As a Site Reliability Engineer, you balance the day‑to‑day operations on production systems with long‑term software engineering improvements to reduce operational toil and foster the reliability, availability, and performance of these systems.

Operations (50%)

• Design, build, and maintain scalable, highly available and fault‑tolerant infrastructures to support our web services and ML workloads.
• Make sure our platform, inference and model training environments are always highly available and enable seamless replication of work environments across several HPC clusters.
• Operate systems and troubleshoot issues in production environments (interrupts, on‑call responses, users admin, data extraction, infrastructure scaling, etc.).
• Implement and improve monitoring, alerting, and incident response systems to ensure optimal system performance and minimize downtime.
• Implement and maintain workflows and tools (CI/CD, containerization, orchestration, monitoring, logging and alerting systems) for both our client‑facing APIs and large training runs.
• Participate occasionally in on‑call rotations to respond to incidents and perform root cause analysis to prevent future occurrences.

Development (50%)

• Drive continuous improvement in infrastructure automation, deployment, and orchestration using tools like Kubernetes, Flux, Terraform.
• Collaborate with AI/ML researchers to develop and implement solutions that enable safe and reproducible model‑training experiments.
• Build a cloud‑agnostic platform offering an abstraction layer between science and infrastructure.
• Design and develop new workflows and tooling to improve the reliability, availability and performance of our systems.
• Collaborate with the security team to ensure infrastructure adheres to best security practices and compliance requirements.
• Document processes and procedures to ensure consistency and knowledge sharing across the team.
• Contribute to open‑source projects, research publications, blog articles and conferences.

About you

• Master's degree in Computer Science, Engineering or a related field.
• 7+ years of experience in a DevOps/SRE role.
• Strong experience with cloud computing and highly available distributed systems.
• Exposure to site reliability issues in critical environments.
• Experience working against reliability KPIs.
• Hands‑on experience with CI/CD, containerization and orchestration tools.
• Knowledge of monitoring, logging, alerting and observability tools.
• Familiarity with infrastructure‑as‑code tools like Terraform or CloudFormation.
• Proficiency in scripting languages (Python, Go, Bash) and knowledge of software development best practices.
• 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.

Your application will be all the more interesting if you also have

• Experience in an AI/ML environment.
• Experience of high‑performance computing (HPC) systems and workload managers (Slurm).
• Worked with modern AI‑oriented solutions (Fluidstack, Coreweave, Vast...).
