Experience: 8+ YearsEstuary 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. With Estuary, teams build reliable, low-latency pipelines—without the overhead of managing data infrastructure.The RoleWe are looking for a Senior Systems Engineer to join our Capture or Materialization teams. These teams are the bridge between Estuary and the rest of the data ecosystem. You will be responsible for building the high-performance connectors that extract data from diverse sources and reliably load it into downstream destinations. Success requires a blend of low-level systems engineering and high-level product intuition. This is a polyglot environment (Go primarily, with Python and Rust where appropriate).What You’ll Do- Master SaaS & Protocol Internals: Research and understand SaaS APIs (e.g., Salesforce, Stripe, NetSuite) and database protocols, handling rate limits, consistency models, and edge cases.- Build Polyglot Integrations: Design and maintain robust, scalable connectors in Go; contribute to Python and Rust components.- Architect for Reliability: Handle distributed state, "exactly-once" delivery guarantees, and backpressure.- Navigate Technical Entropy: Bridge external API realities with core engine performance requirements.- Collaborate & Mentor: Participate in design docs and code reviews.What We're Looking For- 8+ years backend engineering; proficiency in Go plus comfort with Python and Rust- Systems thinking; data fluency (checkpointing, schema drift, consistency models)- Strong fundamentals (concurrency, memory management, networking gRPC/TCP-IP)- Clear communication; equivalent practical experience valuedBonus Points For- Rust experience; data infrastructure background (CDC, Kafka, Flink); open source contributions; startup gritWhy Estuary?- Competitive compensation, equity, and full benefits- Flexible remote work; high-autonomy environment- Quarterly team offsites (Miami, Austin, Boulder, New Orleans)
