Senior Site Reliability Engineer - Data Infrastructure

About this role

Responsibilities
The Data Infrastructure SRE team is responsible for the reliability, scalability, and efficiency of the core data services that power our products. We manage a massive, distributed environment built on technologies like Kubernetes, Redis, MySQL, and Message Queue. Our work is not about building features, but about engineering the resilience and performance of the underlying platform that all product teams depend on. We are the guardians of production, ensuring our data systems run smoothly, nonstop.


This role includes participation in a rotational on-call schedule to ensure nonstop coverage for our critical data infrastructure. You will be expected to respond to, troubleshoot, and resolve production incidents. Our team collaborates across multiple time zones, and you will engage in rigorous change management and post-incident review processes to maintain system stability.


As a Site Reliability Engineer, you will be on the front lines of keeping our large-scale data systems running reliably and efficiently. You will focus on hands-on operational work, from responding to alerts and managing production changes to automating routine tasks. This role is an excellent opportunity to develop deep expertise in modern infrastructure technologies and SRE practices while working alongside senior engineers to solve challenging problems.


Responsibilities:

- Incident response and postmortems: Act as an incident commander for critical production issues, guiding the team through triage and resolution. Drive deep, blameless post-incident reviews and ensure that follow-up actions are implemented to prevent recurrence.

- SLO/SLA and error budgets: Define, negotiate, and maintain Service Level Objectives (SLOs) for critical data services. Champion the use of error budgets to balance reliability work with feature development.

- Capacity and cost optimization: Lead initiatives in capacity planning, performance tuning, and resource management...
