Lead reliability engineering for Reddit's user-facing systems at internet scale
Reddit's Site Experience SRE team sits at the intersection of infrastructure, product engineering, and user experience, covering web, mobile, APIs, feeds, media delivery, and real-time systems. As Staff SRE, you'll architect for massive scale, reduce operational risk, lead incident response, and set reliability standards across the org. This interview tests technical leadership in distributed systems as much as hands-on reliability engineering depth.

What this interview tests
- Designing highly available systems at internet scale (failover, redundancy, capacity planning)
- Leading complex, cross-team incident response and blameless postmortems
- Identifying and mitigating systemic reliability risk before it causes outages
- Defining SLIs/SLOs and driving org-wide reliability/operational standards
- Automation to eliminate repetitive operational work and improve deployment safety
- Technical mentorship and cross-team influence without direct authority
Common question themes
Design a highly available architecture for a user-facing system under massive global load
Walk through the most complex incident you've led — root cause, response, and long-term fix
How do you identify a systemic reliability bottleneck before it causes a major outage
Describe a reliability standard or SLO framework you introduced that other teams adopted
Tell me about automating away a class of repetitive operational toil
How do you mentor engineers and influence reliability culture across teams you don't manage
