Estuary is a real-time data integration platform built for both fast-moving developers and large-scale enterprises. We combine change data capture (CDC), stream processing, and declarative configuration into a unified system that simplifies complex data movement. We are looking for a Senior Site Reliability Engineer to join our team as a foundational contributor to the infrastructure that powers Estuary. This is a high-impact role where you will bridge the gap between backend engineering and operational excellence. You will architect the systems that ensure our real-time data engine remains resilient, secure, and performant at an enterprise scale. You will participate in on-call rotations, contribute to blameless postmortems, and lead technical improvements to harden the system against future failures.
