Workato is building enterprise infrastructure for the agentic era, positioning itself as a leader in Enterprise MCP (Model Context Protocol) and iPaaS. The company connects enterprise systems, data, applications, and AI into a unified, governed platform, trusted by 50% of the Fortune 500. You will join the Gateways & Enterprise AI Infrastructure team to design and develop production-grade services that sit between LLM providers and enterprise systems. This includes building an MCP Gateway and AI Gateway—core infrastructure components handling routing, authentication, rate limiting, observability, and protocol translation. Key responsibilities: • Design and develop the MCP Gateway and AI Gateway: production services mediating between applications, AI agents, and LLM providers. This is protocol-level work including MCP server/client implementations, request routing, streaming, tool-call proxying, authn/authz, and tenant isolation. • Build high-throughput, low-latency network services: work close to the wire with TCP, TLS, HTTP/1.1 and HTTP/2, JSON streaming, connection pooling, and backpressure management. You'll understand where latency lives and how to eliminate it. • Own the data layer from the application side: deep PostgreSQL expertise including schema design, indexing strategies, query planning, transactions, isolation levels, and connection management. You can read EXPLAIN ANALYZE output and optimize queries. You should have strong systems-level thinking, understand both the AI protocol layer and infrastructure layer, and be comfortable building production services in Go and/or Ruby. This is core infrastructure work, not application development on top of platforms.
