/li liProven track record of designing and scaling distributed, highly available systems. /li liDeep network knowledge: TCP connection lifecycle, TLS/mTLS handshake and termination, HTTP/1.1, HTTP/2, HTTP/3 (QUIC), WebSocket, SSE. /li liWorking knowledge of Kubernetes concepts and deployment patterns. /li liApplied cryptography: symmetric/asymmetric encryption, certificate chains of trust, key management, signing and verification. /li li10+ years of professional software engineering experience. /li liExperience with Docker, container orchestration, and cloud infrastructure (AWS, Azure, or GCP). /li liExperience with Redis‑based caching and pub/sub patterns. /li liContributions to open‑source projects. /li liFamiliarity with AI/LLM serving infrastructure: model proxying, token metering, streaming protocols. /li liIntegration with third‑party REST/gRPC APIs at scale (throttling, retries, circuit breaking, batch processing). /li liExposure to API gateway or service mesh internals (e.g., Envoy, Kong, custom proxies). /li liReading‑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. /li liComfortable working in a globally distributed team across multiple timezones (the team spans Singapore, Europe, and the US). /li liStrong written and spoken English — sufficient for design discussions, code reviews, and cross‑team collaboration. /li liOpen to experimentation; pragmatic about adopting new technologies. /li liFull‑cycle product delivery mindset: from problem framing through production and maintenance. /li /ul /p #J-18808-Ljbffr
