The Lead Site Reliability Engineer will join the Compute Site Reliability Engineering team in Helsinki. You will help us scale and harden our self‑managed, multi‑continent compute fleet (currently ~600 servers, growing toward 2030) through pragmatic automation and strong technical leadership.

You will work with the Private Cloud Compute SRE team, responsible for our self‑managed, multi‑continent private cloud data centers and compute fleet. Your work spans OS lifecycle, configuration standards, fleet automation, and reliability/security improvements in a self‑managed datacenter environment. You will collaborate closely with other teams, including network operations, performance testing, and databases.

You will support the reliability, security, and scalability of our compute platform by leading improvements in enterprise Linux operations (with a strong focus on Red Hat Linux), OS configuration, and automation. You’ll act as a strong technical partner to the manager in technical decisions, roadmap scoping, and setting practical standards that help the team scale.

You will contribute to increasing our automation and development focus over time by delivering improvement plans (RFCs), actively contributing to the codebase, and raising team quality through reviews and coaching. On‑call is not mandatory; participation is voluntary.

• Experience in enterprise Linux environments, ideally with Red Hat (RHEL), including troubleshooting, monitoring, package management, OS installation, and secure configuration at large scale.
• Ability to lead technically through architecture decisions, RFCs, and setting standards while staying hands‑on in code and automation.
• Skills in automation and configuration management, with strong Ansible proficiency (our main tool) and solid Git Hub/Git Lab workflow experience.
• Experience operating and scaling self‑managed, multi‑continent data‑center environments (or similarly complex private infrastructure).
• Familiarity with Java‑based workloads in production environments.
• Comfortable with using AI in everyday work and developing AI tool usage as a larger organizational strategy.
• Fluent in written and spoken English.
• Bonus: experience with Python, Terraform, Kubernetes, international teamwork, great communication and organizational skills, and Finnish language skills.

• An international career and learning opportunities.
• A rapidly growing and financially robust software company with exciting opportunities for career growth.
• Flexibility in how you work (while being based in Helsinki).
• Room to thrive in a fast‑growing global company with a strong market position.
• Practical benefits supporting work, family, wellness, and everyday life.
• Annual leave.
• Diverse, inclusive, and supportive work culture.
• Work that meaningfully reduces waste and improves sustainability.
• Ownership, autonomy, and flat hierarchies.
