Role Description We are looking for a Senior Backend Engineer (GoLang) with deep Go expertise to join the Gateways team. This is a hands-on individual contributor role with expectations to own subsystems end-to-end and drive technical direction in your area of ownership. The Gateways team owns Workato's API management, gateway, and routing infrastructure — the layer that sits between external consumers and the platform's core services. Our scope includes: - Classic API Management (APIM) product - AI Gateway for LLM traffic management - MCP Gateway for Model Context Protocol integration We operate at high scale, low latency, and with strict availability requirements. Responsibilities - Design, build, and operate high-performance gateway and routing components in Go - Own technical direction for your area: author design documents, lead architectural reviews, evaluate trade-offs, and drive decisions to conclusion - Build and evolve infrastructure for authentication, caching, rate limiting, request queuing, and traffic shaping - Collaborate with SRE, Infrastructure, and Platform teams to meet availability, scalability, and observability requirements - Stay current with relevant technologies, protocols, and industry patterns; present findings and proposals for architectural review - Deliver features end-to-end: from design through production rollout and ongoing maintenance Qualifications - 10+ years of professional software engineering experience - 5+ years of hands-on backend development in Go, with strong command of concurrency patterns, performance profiling, and idiomatic design - Deep understanding of Go internals: scheduler, garbage collector, memory model, and runtime behavior under load - Strong systems programming foundation: understanding of how things work below the application layer - Deep network knowledge: TCP connection lifecycle, TLS/mTLS handshake and termination, HTTP/1.1, HTTP/2, HTTP/3 (QUIC), WebSocket, SSE - Applied cryptography: symmetric/asymmetric encryption, certificate chains of trust, key management, signing and verification - Proven track record of designing and scaling distributed, highly available systems - Solid understanding of large-scale web infrastructure: load balancers, reverse proxies, application servers, databases, message brokers, caching layers, and observability stacks - Experience authoring system/architecture design documents and leading technical reviews - Ability to identify bottlenecks at both the code level and the system level, and propose pragmatic solutions - Working knowledge of Kubernetes concepts and deployment patterns - BS/MS in Computer Science, Engineering, or equivalent demonstrated experience Requirements - Reading-level familiarity with Ruby (on Rails) — the Workato platform core is Ruby-based and owned by other teams, but integration points require the ability to navigate and understand existing code - Familiarity with AI/LLM serving infrastructure: model proxying, token metering, streaming protocols - Experience with Docker, container orchestration, and cloud infrastructure (AWS, Azure, or GCP) - Experience with Redis-based caching and pub/sub patterns - Exposure to API gateway or service mesh internals (e.g., Envoy, Kong, custom proxies) - Integration with third-party REST/gRPC APIs at scale (throttling, retries, circuit breaking, batch processing) - Contributions to open-source projects Soft Skills - Comfortable working in a globally distributed team across multiple timezones (the team spans Singapore, Europe, and the US) - Strong written and spoken English — sufficient for design discussions, code reviews, and cross-team collaboration - Full-cycle product delivery mindset: from problem framing through production and maintenance - Open to experimentation; pragmatic about adopting new technologies

• Offer architectural guidance • Spearhead critical design choices • Guarantee delivery adheres to enterprise architecture and platform standards
