Lead Site Reliability Engineer (H/F) - Social Media

Founded by the team behind one of the most successful location-sharing apps in the world, this startup is already handling massive global traffic (millions of active users across 20+ countries) and is preparing for its next phase of explosive growth.

Job Context: The scale is already elevated (peaks at 100k+ requests/second), and the next milestone is critical. The challenge is to lead a small, high-performing SRE team while remaining 90% hands-on to define and execute the long-term infrastructure vision.

Responsibilities:

• Define and execute the SRE strategy for the coming years (performance, reliability, observability, FinOps, security and compliance).
• Design, maintain, and scale distributed databases across multiple clusters (e.g., high-throughput monitoring for 1M+ series per second).
• Eradicate manual tasks by automating everything from the ground up (monitoring dashboards, database installations, cluster management).
• Optimize Kubernetes autoscaling to achieve near 90% CPU efficiency without compromising service quality.
• Act as a Software Engineer: build CI/CD pipelines, write code, and bring new tools to production to help the company scale faster.
• Partner closely with the backend engineering team to ensure smooth, reliable code deployments.
• Act as the primary SRE point of contact for top management.

Stack: GCP, Kubernetes, Datadog, ScyllaDB, Redpanda, Rust, Go.

Experience: You have a proven track record of surviving and thriving in an explosive scale-up/high-traffic environment. You are 80-90% hands-on but capable of driving high-level strategy. You have a "low ego", a pragmatic mindset, and ideally a strong background in software development.

Conditions:

• Around €140k base salary, depending on the profile, plus equity (BSPCE).
• Located in central Paris (100% on-site in a beautiful Parisian-style office).
• Full relocation package available (visa sponsorship, 1st month Airbnb, relocation agency, French lessons).
