Senior Site Reliability Engineer

As a Senior Site Reliability Engineer, you're responsible for the reliability, performance, and scalability of production systems. Your day might involve reviewing monitoring dashboards for anomalies, building automation to eliminate manual operations, responding to an incident when services degrade, or planning infrastructure changes to handle growth. At the senior level, you're trusted to design and implement significant infrastructure changes, lead incident response, and make architectural decisions that affect system reliability.

The work is a unique blend of software engineering and operational ownership. You're writing code — infrastructure as code, monitoring automation, deployment pipelines — but you're also on-call, meaning production issues become your problem regardless of when they happen. You're measuring everything: latency, error rates, resource utilization, deployment frequency. The best SREs are constantly eliminating toil, automating repetitive work, and building systems that scale without proportional increases in operational burden.

The hardest part is the on-call responsibility and the pressure of production ownership. When things break at 2am, customers are affected and revenue is at risk. You need to troubleshoot complex distributed systems under pressure while coordinating with other teams. People who thrive here love the intellectual challenge of complex systems and find satisfaction in building resilient infrastructure — they're comfortable with the reality that perfection is impossible, but resilience and quick recovery are achievable.
