[Hiring] Site Reliability Engineer @Centric Software

Role Description

In your new role as Site Reliability Engineer, you will support us right in the heart of our SaaS, as an integral member of the Site Reliability Engineering team. You will be responsible for the Shoppingfeed product, working in close relations with our software developers and infrastructure engineers, but also with our security and QA colleagues.

Your everyday work will involve a diverse range of tasks with lots of space for development:

• Diagnose and resolve application-level reliability and performance issues across the pull request path (nginx -> php-fpm -> application -> database/cache).
• Tune and scale the web-serving layer under production load — php-fpm pool sizing and process management, nginx timeouts/buffering/upstream keepalive, capacity planning.
• Solid experience configuring and troubleshooting nginx as a reverse proxy / web server (timeouts, buffering, upstream keepalive, diagnosing 502/504s).
• Proven experience diagnosing and resolving performance and scaling problems under load (latency, worker/pool saturation, capacity planning).
• Develop, maintain, and support our own Docker-based workloads.
• Own the product deployment and upgrade process end to end.
• Support and troubleshoot running customer-facing services.
• Work 50% of your time with our product teams, ensuring much-needed improvements get defined, explained, worked on, and rolled out.
• Continuously help improve both our product and the infrastructure underneath, by taking responsibility together with your team.
• Define reliability metrics and ensure they are kept by all the systems you oversee.
• Be part of our On-Call and On-Duty rotations.
