Lead Product Manager, Technical Infrastructure

Get to Know the Team

We are Grab's centralised Platform Engineering team — the builders and custodians of the foundational technology stack that powers everything from consumer apps to autonomous agents. Our domains span Developer Experience, Infrastructure Foundations, Reliability Engineering, and AI/Agentic infrastructure. With thousands of engineers relying on our platform daily, we operate at a scale where the quality of our tooling directly shapes the speed and safety of Grab's product development. We move fast, hold high standards, and care deeply about the developer community we serve.

Get to Know the Role

As Lead Product Manager, Infrastructure Platforms, you will own the product vision, strategy, and execution for Grab's core engineering platform - the backbone that enables 1,000+ microservices, hundreds of tools and agents, and thousands of engineers to build and run high-quality products quickly, reliably and securely.

You will report into the Head of Product, Technical Infrastructure and work in a hybrid setup from our Singapore office. You will be supported by dedicated engineering & design teams and will have direct influence over how Grab's engineers experience their craft every day.This is a high-impact, high-autonomy role for someone who thrives at the intersection of deep technical understanding and product excellence. If you're energised by building platforms that multiply the effectiveness of an entire engineering organisation - and want to do it at Grab's scale — we'd love to hear from you.

The Critical Tasks You Will Perform

• Own the platform product roadmap: Define and drive your roadmap end-to-end, aligning with engineering leadership on priorities, trade-offs, and delivery milestones that reflect real developer pain points.
• Set strategy and success metrics: Frame clear problem spaces, define KPIs and OKRs, and track adoption and outcome metrics to ensure platform investments translate into measurable developer productivity gains.
• Drive adoption of platform solutions : Partner with internal engineering customers to understand their workflows, champion new capabilities, and ensure teams are effectively adopting platform products — not just shipping features.
• Write and iterate on high-quality PRDs : Collaborate deeply with engineering teams to produce rigorous, well-scoped Product Requirements Documents and see them through to high-quality execution with minimal rework.
• Champion developer experience through research — Regularly engage Grab's engineering community to surface friction points, synthesise insights, and translate them into prioritised product improvements.
• Leverage GenAI for productivity : Use AI tools (e.g. Copilots, LLM-assisted PRD drafting, data summarisation tools) to accelerate research, documentation, stakeholder communication, and roadmap analysis — and bring this mindset into how the team works.
• Introduce thought leadership in platform engineering: Benchmark Grab's platform against industry best practices, identify capability gaps, and advocate for the investments that keep Grab's developer platform world-class.
