ZenRows - Senior Software Engineer

• 10+ years of backend engineering experience, with meaningful time spent building and operating high-throughput, high-availability distributed systems • Strong fundamentals in concurrency, fault tolerance, consistency models, and systems design • Hands-on experience with queueing and messaging systems (SQS, Kafka, RabbitMQ, Pub/Sub, BullMQ, or similar) • Comfortable operating at scale — tens of millions of requests or events per day, across multiple nodes or regions • Solid production instincts: you think about retries, deduplication, backpressure, and observability before writing the first line • Clean, maintainable code in Go (or a comparable backend language) • Experience with distributed tracing, metrics, and logging (OpenTelemetry, Prometheus, Grafana, or equivalent) • Clear communicator — you can drive a technical debate and explain complex tradeoffs to non-engineers alike • Bonus • Experience with browser automation at scale (Playwright, Puppeteer, or similar) • Familiarity with proxy infrastructure, TLS fingerprinting, or HTTP-level anti-bot patterns • You've designed or operated a workflow engine, job scheduler, or orchestration system • You have a war story from a system that broke badly in production — and clear lessons learned from it • Multi-cloud deployment experience • What Makes This Different • Full ownership. You'll own systems end-to-end — design, deployment, and operations. No handoffs to an ops team, no waiting for someone else to ship your work • Full ownership. • Direct impact. The systems you build directly affect customer SLAs, billing accuracy, and the core product success rate. You'll feel it • Direct impact. • No layers. You'll work closely with our CEO and Director of Engineering — both technically deep — without three layers of management in between • No layers. • No methodology theater. We skip the ceremony and give you a horizontal view of the problem. You decide where you can have the most impact • No methodology theater.
