Engineering Manager II, Backend - Gateway platform at Grab

Get to Know the Team The Sentry team owns Grab's tier-0 API Gateway Platforms, sitting in the traffic path for almost every request between our apps, backend services, and external partners. We design, build, and operate our own API Gateway solution called T6, providing secure, reliable routing, traffic management, and service discovery so that millions of rides, deliveries, and payments just work. Our scope spans core gateway infrastructure, reliability engineering, and self-serve experiences that let product teams manage their own configs safely and at scale. We are a distributed team across Singapore, Vietnam, and Malaysia, working closely with Cloud Infra, Security, and product engineering teams. Day to day, we partner with internal service owners by improving stability, simplifying migrations from legacy gateways to T6, and building self-serve tools, so engineers and service owners can ship changes faster with stronger guardrails. If you care about platform reliability, product thinking users, and leading teams through large-scale migrations and bold bets, you'll feel at home here. Get to Know the Role As an Engineering Manager II for the API Gateway Platform in the Sentry team, you will lead a high-impact platform group that keeps Grab's tier-0 gateways reliable, secure, and evolving. You will guide the team that is driving our journey from legacy API Gateway to T6, while continuously improving the developer experience and self-serve capabilities for internal service teams. You will be accountable for setting the technical direction, aligning stakeholders, and building a strong engineering culture around ownership, operational excellence, and product thinking for internal users. You will report to the Singapore-based hiring manager and work onsite at CMC Creative Space, HCMC. The Critical Tasks You Will Perform • Own the roadmap and execution for the API Gateway Platform, including migrations from legacy API Gateways to T6, new gateway capabilities, and deprecation of legacy paths. • Drive reliability and operational excellence by shaping SLOs, on-call and incident practices, BCDR readiness, and guardrails that keep our gateways stable at scale. • Partner with cross-functional teams (Cloud Infra, Security, product engineering and platform teams) to design and deliver gateway features such as authentication, routing, traffic management, and partner integrations. • Build, grow, and coach the team, creating clear expectations, feedback loops, and growth plans so engineers can take end-to-end ownership of challenging platform work. • Champion self-serve and great user experience, collaborating on self-serve tools, so service owners can safely manage their own configs with strong defaults and automation. • Adopt AI-assisted development and automation where it makes sense, using it to speed up migrations, improve quality, and free the team to focus on
