Staff Site Reliability Engineer

Role Overview

Thrive Market is hiring a Staff Site Reliability Engineer to define and build the reliability foundation for its platform. You will establish the company’s SRE practice from the ground up—setting SLOs/SLIs and error budgets, improving observability, and creating frameworks to ensure systems scale reliably during rapid growth.

Responsibilities

Reliability & Observability

• Define, implement, and own SLOs and SLIs for critical platform services.
• Build and maintain monitoring/alerting/observability using tools such as Datadog, Prometheus, and Grafana.
• Establish error budgets to balance feature velocity with reliability investments.
• Lead incident response, run blameless postmortems, and drive systemic improvements to prevent recurrence.
• Design and implement chaos engineering practices to proactively identify failure modes.

Infrastructure & Platform

• Architect and optimize the Kubernetes-based container orchestration platform for reliability, performance, and cost efficiency.
• Support infrastructure and platform migrations with minimal business disruption.
• Contribute to evaluation/execution of a potential migration to a next-generation ecommerce platform with reliability planning and risk mitigation.
• Design and implement automated deployment pipelines with feature flags and rollback/roll-forward capabilities.
• Own disaster recovery, capacity planning, and system hardening initiatives.
• Work with product engineering teams to help scale infrastructure in AWS and apply SRE best practices.

Culture & Process

• Establish SRE as a practice: charter, processes, and engagement model with product engineering.
• Promote operational excellence and data-driven reliability decisions (continuous improvement).
• Maintain technical documentation: architecture decisions, runbooks, incident procedures, and operational playbooks.
• Participate in weekly on-call and help build sustainable on-call practices.
• Identify systemic issues/inefficiencies and recommend improvements across engineering.

Requirements

• B.S. in Computer Science (or equivalent experience).
• 7+ years of hands-on experience in SRE, DevOps, or Infrastructure Engineering, with a strong track record of improving reliability in fast-growing environments.

Nice-to-Haves

• Familiarity with The Google SRE Handbook, Accelerate, The DevOps Handbook, and related reliability/engineering practices.
• Experience building SRE practices from scratch and leading reliability strategy alongside product engineering.

Location

• Los Angeles, CA
