Experience: 8+ Years. Build high-performance connectors that extract data from diverse sources and reliably load downstream. Blend low-level systems engineering with high-level product intuition in a polyglot environment (primarily Go, plus Python and Rust as needed).What You’ll Do:- Master SaaS & protocol internals (e.g., Salesforce, Stripe, NetSuite; rate limits, consistency models, edge cases).- Build polyglot integrations in Go with components in Python/Rust.- Architect for reliability with distributed state, 'exactly-once' guarantees, and backpressure management.- Bridge the 'messy' realities of external APIs with core engine performance.- Collaborate & mentor via design docs and reviews.What We're Looking For:- 8+ years backend engineering; production systems at scale.- Proficient in Go; comfortable with Python and Rust.- Systems thinking; data fluency (checkpointing, schema drift, consistency trade-offs).- Strong fundamentals (concurrency, memory, networking gRPC/TCP-IP); clear communication.- Practical experience valued over formal degree.Bonus: Rust experience; CDC/Kafka/Flink background; open-source contributions; startup grit.Why Estuary: Competitive compensation, equity, full benefits; flexible remote work; high autonomy; quarterly team offsites.
