Experience: 8+ Years. Estuary combines CDC, stream processing, and declarative configuration to simplify complex data movement. The Role: Join the Capture or Materialization teams to build high-performance connectors that extract data from diverse sources and load it into downstream destinations. Success requires low-level systems engineering and high-level product intuition; deeply investigate SaaS platforms and databases, uncover constraints, and architect robust real-time data movement in a polyglot environment (primarily Go, with Python and Rust where best). What You’ll Do: Master SaaS & Protocol Internals — research and understand the \"behavior\" of SaaS APIs (Salesforce, Stripe, NetSuite) and database protocols, considering rate limits, consistency models, and edge cases; Build Polyglot Integrations — robust, scalable connectors primarily in Go, with components in Python and Rust; Architect for Reliability — distributed state, \"exactly-once\" guarantees, backpressure; Navigate Technical Entropy — reconcile messy external APIs with high-performance core; Collaborate & Mentor — design docs, code reviews, and high standards. What We're Looking For: 8+ years backend engineering building/operating production-grade systems; Pragmatic Polyglot — strong in Go, comfortable with/learning Python & Rust; Systems Thinking — enjoy deep dives into third-party docs and API behavior; Data Fluency — checkpointing, schema drift, consistency trade-offs; Strong Fundamentals — concurrency, memory management, networking (gRPC, TCP/IP); Clear Communication. Practical Experience valued over formal degrees. Bonus Points: Rust experience; Data infrastructure background (CDC, Kafka, Flink); Open source contributions; Startup grit. Why Estuary: Competitive compensation, equity, full benefits; Flexible remote work; High-autonomy impact; Quarterly team offsites (Miami, Austin, Boulder, New Orleans).
