Job Description
Build the System Behind the Grab SuperApp
We are a SuperApp operating at massive scale across transport, food, commerce, ads, merchant platforms, and enterprise services. Within this ecosystem, BECO (Business Ecosystem) powers the foundational platforms that connect merchants, consumers, ads, transactions, search, and intelligence.
We are now entering our next phase:
Embedding G/AI into the engineering nervous system
Raising reliability to utility-grade standards
Unifying siloed platforms into a cohesive ecosystem
Accelerating new businesses with AI-native architecture
To do this, we are hiring a Senior Principal Engineer — a rare, high-leverage individual contributor who will shape the technical trajectory of a 300+ engineer organisation. This role reports directly to the Head of BECO.
Why This Role Is Special
Most Principal roles influence a team. Some influence a domain. This role influences an entire engineering organisation. You will operate across five major departments spanning: 1). Merchant platforms, 2). Search & personalisation, 3). Ads & monetisation, 4). Transaction systems, 5). Enterprise capabilities
You are not here to own a microservice. You are here to evolve the system.
The Mission
Turn AI Into Engineering Leverage
We are moving beyond “AI demos.” You will help architect and scale:
AI-assisted development workflows
Agentic operational automation
Reliability guardrails powered by AI
Safe, test-backed automation systems
The goal is measurable improvement in:
Engineering velocity
Code quality
Operational efficiency
You will shape how AI becomes embedded into how engineers work — not as a tool, but as infrastructure.
2. Build Reliability That Feels Invisible
We believe reliability should feel like running water — always there, never noticed. You will:
Raise prevention standards across critical systems
Institutionalise chaos engineering as discipline
Strengthen detection and recovery mechanisms
Reduce incident impact structurally, not reactively
This is about engineering maturity at scale.
3. Break Platform Silos
Search, Ads, Promo, Transactions, Data — today these evolve in parallel. We are building a unified ecosystem where:
Ranking frameworks converge
User understanding powers multiple surfaces
Data infrastructure reduces cost and instability
Shared capabilities unlock new business models
You will design the connective tissue that makes platformisation real.
4. Architect for Pattern-Breaking Growth
We are launching new businesses in e-commerce, AI agents, conversational transactions, and gamified engagement experiences. The challenge: Move fast without creating tomorrow’s technical debt. You will:
Design clean 01 foundations
Define execution models optimised for velocity
Enable AI-native product experiences
Balance exploration with ecosystem coherence
Qualifications
Who Thrives Here
You are a rare combination of:
Deep distributed systems thinker
Fluent in AI/ML system realities
Opinionated about engineering culture
Comfortable influencing senior stakeholders
Energised by ambiguity
High-agency and low-ego
You likely have:
Operated at Staff+/Principal level in large-scale systems
Driven cross-organisation architectural change
Built or evolved platforms used by millions
Touched reliability, search, ML, or transaction-heavy systems
You care about leverage.
You care about second-order effects.
You care about building systems that outlast you.
The Kind of Problems You’ll Solve
How do we embed LLM agents safely into engineering workflows at scale?
How do we raise reliability standards without slowing innovation?
When do we centralise vs federate capabilities across domains?
How do we unify ranking and recall systems across monetised and organic surfaces?
How do we launch new AI-native businesses without fracturing the ecosystem?
These are not ticket-level problems.
They are system-shaping decisions.
What Success Looks Like (12–18 Months)
AI-assisted engineering is a daily reality, not a pilot
Reliability metrics trend structurally stronger
Cross-platform capabilities converge
At least one new business launches on a clean, scalable foundation
Engineering quality becomes institutionalised, not tribal
Why Join Now
You will join at an inflection point:
The ecosystem is large enough to matter
The ambition is bold enough to be meaningful
The mandate is clear enough to act
This is a role for someone who wants to shape how a SuperApp evolves technically over the next decade. If you want to:
Influence 300+ engineers without managing them
Architect systems that span AI, reliability, monetisation, and commerce
Leave a structural mark on a major technology platform
We’d love to talk.
