Senior Backend Engineer (GO, API Gateways)

• We are looking for a Senior Backend Engineer (Go Lang) 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 the classic API Management (APIM) product, an AI Gateway for LLM traffic management, and an MCP Gateway for Model Context Protocol integration
• We operate at high scale, low latency, and with strict availability requirements
• 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

Benefits

• Flexible Working Arrangements: We maintain a hybrid remote work model and provide everyone with best‑of‑breed technology tools that enable them to work anywhere, anytime.
• Great
• Employee

Benefits: Such as an Employee Assistance Programme (EAP), Health Insurance, Referral Bonuses, and Workato Stock Options, tailored to the countries that our employees are based in.

• Professional Development Opportunities: We support individual career ambitions, and set aside training programs and budgets they can tap on to upgrade both soft and hard skills.
• Recreation Time: From virtual game nights to fitness sessions, there’s always time for a little fun on the calendars.
• Dedicated Wellness: We make it a point to dedicate time to pause, recharge and get to know each other better.

Qualifications

• BS/MS in Computer Science, Engineering, or equivalent demonstrated experience
• 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
• Solid understanding of large‑scale web infrastructure: load balancers, reverse proxies, application servers, databases, message brokers, caching layers, and observability stacks
• Proven track record of designing and scaling distributed, highly available systems
• Experience authoring system/architecture design documents and leading technical reviews
• Applied cryptography: symmetric/asymmetric encryption, certificate chains of trust, key management, signing and verification
• Working knowledge of Kubernetes concepts and deployment patterns
• 10+ years of professional software engineering experience
• Ability to identify bottlenecks at both the code level and the system level, and propose pragmatic solutions
• 5+ years of hands‑on backend development in Go, with strong command of concurrency patterns, performance profiling, and idiomatic design
• Deep network knowledge: TCP connection lifecycle, TLS/m TLS handshake and termination, HTTP/1.1, HTTP/2, HTTP/3 (QUIC), Web Socket, SSE
• 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 Redis‑based caching and pub/sub patterns
• Experience with Docker, container orchestration, and cloud infrastructure (AWS, Azure, or GCP)
• Exposure to API gateway or service mesh internals (e. g., Envoy, Kong, custom proxies)
• Integration with third‑party REST/g RPC APIs at scale (throttling, retries, circuit breaking, batch processing)
• Contributions to open‑source projects
• Open to experimentation; pragmatic about adopting new technologies
• Full‑cycle product delivery mindset: from problem framing through production and maintenance
• Strong written and spoken English — sufficient for design discussions, code reviews, and cross‑team collaboration
• Comfortable working in a globally distributed team across multiple timezones (the team spans Singapore, Europe, and the US)
