Senior Site Reliability Engineer (AWS)

As a Senior Site Reliability Engineer on our cloud engineering team, you'll keep our production environment healthy, secure, and running smoothly. This is an operations-focused role: you'll own the day-to-day administration of our AWS accounts and databases, backup posture across our data stores, and production monitoring and debugging for a fully serverless platform. Your work will span the operational side of the software development life cycle — from deployment to maintenance and updates — always striving for continuous improvement. You'll keep our infrastructure clean, easily deployable, and scalable, creating a stable operating environment for the whole team. Responsibilities - Own day-to-day administration across AWS services, accounts, and access, as well as database administration across PostgreSQL and our other data stores. - Own backup posture across databases, S3 buckets, and queues; verify restores regularly and maintain a tested disaster recovery plan. - Proactively monitor production — CloudWatch dashboards, metric alarms, log-based metrics, and Slack alerting — addressing operational issues before they impact users. - Lead production debugging and incident response: build and maintain runbooks, participate in the on-call rotation, and resolve queue and dead-letter-queue failures through retry, redrive, and recovery. - Continuously refine our infrastructure to ensure it is easily deployable and scalable: keep infrastructure as code (SST/Pulumi) accurate, retire unused infrastructure, and keep cost visible and justified. - Share your knowledge of production operations with the team, fostering a culture of learning and growth. Qualifications: Knowledge, Skills, & Abilities - Bachelor's degree and 4-6 years of related experience or equivalent work experience. - 5+ years of experience in DevOps, site reliability, or platform operations, with significant responsibility for production systems. - 3+ years of hands-on experience with AWS, with an emphasis on serverless services (Lambda, SQS, EventBridge, CloudWatch, S3). - Strong database administration experience: PostgreSQL operations, backup and recovery, and query performance; comfort administering other data stores. - Proficiency in scripting languages such as TypeScript, Python, and bash for production automation and operational tooling. - Strong understanding of Linux, DNS, TLS, Docker, GitHub Actions, and infrastructure as code (SST, Pulumi, or Terraform). - Experience with production monitoring and alerting, incident response, and on-call ownership.
