Sr. Site Reliability Engineer

About the Role

We are seeking a Senior Site Reliability Engineer (SRE) to help ensure the stability, scalability, and reliability of our services and infrastructure. This role focuses on building automation, maintaining observability, and supporting incident response to keep customer-facing systems performing at their best. The SRE will collaborate with engineering, product, and operations teams to embed reliability practices into day-to-day development and operations while contributing to tools and processes that improve efficiency and reduce manual effort.

What You'll Do

• Service Reliability & Operations: Own and drive the availability, durability, and performance of critical services across all production environments.


• Lead and champion complex projects from problem discovery through complete, cross-functional resolution, demonstrating high-level technical ownership.


• Define, establish, and enforce service health standards, including working with engineering leadership to implement SLIs, SLOs, and error budget policies for multiple services.


• Lead critical incident response and post-incident reviews, translating findings into strategic, long-term service improvements and architectural changes.


• Mentor others and act as a subject matter expert in following and evolving established ITIL/OSS processes (incident, change, problem, and capacity management).


• Automation & Tooling: Design and architect scalable automation solutions to eliminate toil and improve the efficiency of operational tasks across the entire platform.


• Drive the strategic direction of monitoring, logging, and alerting frameworks (e.g., Prometheus, Grafana, Catchpoint, ELK), and integrate them for comprehensive observability.


• Build, maintain, and secure advanced CI/CD pipelines, configuration management, and complex infrastructure as code solutions (Terraform, Ansible, Jenkins).


• Write production-grade code (Bash, Python, Go, etc.) to develop new reliability tools and enhance existing systems.


• Collaboration: Act as a principal partner to engineering, product, and operations teams, consulting on resilient system design, architecture, and operation.


• Lead and formalize the Production Readiness Review (PRR) process, ensuring robust operational handoff for all new services and features.


• Lead capacity planning and disaster recovery strategy across critical infrastructure components.


• Manage the relationship with vendors and service providers to troubleshoot systemic issues and ensure strict adherence to SLA performance.


• Drive the creation of high-quality documentation, proactively share advanced learnings, and cultivate a reliability-first engineering culture across teams.


• Continuous Improvement: Own the creation, maintenance, and dissemination of operational playbooks, runbooks, and detailed system documentation.


• Proactively identify systemic, recurring issues and architect and drive the implementation of long-term improvements and strategic design action plans.


• Be a leading voice in promoting and embedding reliability-focused practices within development and operations teams.
