Opportunity

We are seeking an experienced Site Reliability Engineer to build reliable, observable systems that enable client teams to operate with confidence at scale. You'll work embedded within cross-functional teams—partnering with developers, platform engineers, and operations teams—to reduce toil, improve system reliability, and prevent incidents before they impact users.

As a Senior Site Reliability Engineer, you take ownership of system reliability across our full backend stack—from AWS infrastructure (ALB, ECS/Fargate, Aurora) to Python services. You design and maintain observability systems, define SLAs and error budgets, build incident response processes, and drive improvements in uptime and performance. You'll participate in 24/7 P0 on-call rotations with a 10-minute acknowledgment SLA, lead incident investigations and postmortems, and help teams shift from reactive firefighting to proactive reliability engineering. You'll also mentor and onboard additional SRE engineers as the team scales from 4 to 8-12 over the coming months.

The Site Reliability Engineer will work shoulder-to-shoulder with cross-functional teams to ensure systems remain resilient, scalable, and observable across client environments. You'll also have opportunities to advise leadership on reliability strategy and help shape how organizations approach operational excellence.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
