Staff Site Reliability Engineer

Mission

Join Qonto as a Staff Site Reliability Engineer to be the strongest technical voice on our Platform Reliability team. Help us scale a reliable infrastructure as Qonto grows toward 1 million customers across Europe.

Impact

As a Staff SRE, you will play a key role in shaping how our platform evolves. You will frame complex infrastructure challenges, drive architectural decisions, and enable the entire tech department to ship faster and more reliably. You'll be a key technical reference, a mentor for junior engineers, and an active contributor to our knowledge-sharing culture. The SRE department is divided into 2 teams (18 talented engineers): Platform and Storage. You will join the Platform Reliability team, who believe that reliability is built before problems happen, not after.

Responsibilities

• Frame complex infrastructure problems, propose clear solutions, and drive projects end-to-end on your own initiative.
• Work with backend, data, security, and engineering efficiency teams to design, deploy, and maintain our infrastructure.
• Spend 20 to 40% of your time writing Go services, tools, and APIs, adhering to the same standards as our backend engineers.
• Automate repetitive tasks to minimize toil.
• Ensure the platform is visible and debuggable through logs, metrics, and tracing.
• Participate in the on-call rotation, lead post-incident reviews, and implement lasting fixes for incidents.
• Share knowledge, challenge ideas, and mentor teammates.

• Deep cross-team collaboration: participate in spec reviews, brainstorming sessions, and problem-solving with various teams.

About You

• Experience: Strong hands-on experience with cloud-native infrastructure in production, including managing Kubernetes clusters at scale.
• Programming Skills: Solid Go experience (or equivalent) and comfort building tools, services, and automation.
• AI-driven Engineering: Active use of AI tools to enhance speed, code quality, and problem-solving; curiosity for future AI advancements.
