About Grab and Our Workplace
Grab is Southeast Asia's leading superapp. In Grab, purpose gives us joy and we harness the power of Technology and AI to deliver the mission of driving Southeast Asia forward by economically empowering everyone, with heart, hunger, honour, and humility.
Get to know the team
The AV Integrations & Deployments (AVID) team builds the integration services, operational tools, and fleet management portal that connect Grab with a diverse fleet of autonomous vehicles. We develop APIs and large-scale telemetry ingestion, real-time fleet monitoring, safety workflows, and depot operations to deploy AV technologies safely, reliably, and at scale across our ecosystem. Our mission is to make Grab the indispensable operating partner for AV fleets in Southeast Asia, building the platform and guide that defines how hybrid human and robot fleets operate in the region.
The Role
As a fullstack engineer, you will help design and build world-class commercial-ready fleet operation portals and internal tools. You will collaborate with global AV partners and fleet operation teams to grow hybrid human-robot fleets in the region. You will report to the Head of Engineering and will be onsite at Grab One-north.
What You'll Do
Build fullstack solutions for the AV fleet operations portal. Design real-time geospatial experiences (e.g., Mapbox GL, deck.gl) to visualise vehicle positions, routes, geofences, clustering, and live status/alerts. Implement secure, low-latency video streaming and playback from vehicles (e.g., RTSP/RTP to HLS/DASH/WebRTC), including access controls, masking/redaction, and audit logging.
Develop performant backend services (Go/Python), efficient web interfaces (e.g., Next.js with SSR/SSG), and real-time interfaces using WebSocket/Server-Sent Events/streamable and gRPC.
Apply reliability, observability, and safety practices (SLOs, metrics, tracing, and alerting). Join on-call rotations, run incident response, root-cause analysis, and contribute to post-mortems.
Design infrastructure with Terraform on AWS/Azure; build CI/CD pipelines and automate testing and deployments.
Model and store operational and time-series data (e.g., Postgres/TimescaleDB/ClickHouse) to power dashboards, analytics, and operational workflows.
Uphold security and privacy-by-design (authN/authZ, secrets management, least-privilege, secure partner integrations, PII/video handling).
Collaborate with product managers, data analysts, designers, and operations teams to define features, ship iteratively, and measure impact. Write clear technical documentation.
Work in a regional organisation, partnering across diverse teams and cultures.
Qualifications
Technical must-haves
Computer science fundamentals: data structures, algorithms, multithreading, distributed systems, relational and non-relational databases.
4+ years of experience with modern frontend frameworks (e.g., Next.js) and SSR/SSG patterns; familiarity with real-time protocols (WebSocket, streamable gRPC).
Experience with geospatial systems and map rendering (e.g., Mapbox GL, deck.gl) and spatial data modelling.
3+ years of experience with cloud platforms (AWS/Azure) and hands-on experience deploying scalable backend services.
4+ years of experience with real-time data processing using Kafka/Flink or similar streaming technologies.
A shift-left testing mindset: unit, integration, and automated testing as part of CI/CD.
Soft Skills Must-haves
Collaborate across teams and regions.
Apply analytical and system design capabilities to develop reliable infrastructure for future growth.
Manage workload and adjust priorities as project needs evolve.
Ensure technical knowledge is well-maintained by producing clear, precise, and user-friendly documentation.
Nice-to-haves
Familiarity with running large-scale web services and understanding of systems internals and networking.
Experience with streaming media and real-time communications (RTSP/RTP, HLS/DASH, WebRTC) and related performance/security considerations.
Hands-on experience with Go programming language.
Hands-on experience with AWS/Azure and cost/operability best practices.
Hands-on experience with Flink/Kafka and stateful stream processing.
Hands-on experience with GraphQL for schema-driven APIs and type-safe clients.
Experience with device/edge management, OTA updates, and secure partner integrations.
Background in safety-critical or regulated environments, privacy-by-design, and threat modelling.
