Senior Systems Engineer (AI Infrastructure) Job in Singapore 2026

A well-funded AI infrastructure company in Singapore is hiring a Senior Systems Engineer (AI Infrastructure) to design and scale core systems powering large-scale search, retrieval, and AI-native applications. This role offers Employment Pass visa sponsorship and relocation support, with total compensation reaching up to USD 300,000 plus meaningful equity.

This opportunity is tailored for senior engineers seeking deep systems-level work at genuine internet scale, operating significant GPU clusters and distributed compute environments within a high-calibre, performance-driven team.

About Role As a Senior Systems Engineer, you will architect and optimise the foundational infrastructure that enables large-scale data ingestion, distributed crawling, embedding model workflows, and high-performance backend services. This role sits at the intersection of systems engineering, distributed computing, and AI infrastructure.

You will focus on performance, reliability, observability, and scalability across compute-intensive workloads, ensuring infrastructure can support evolving AI-native products.

Working within a small and technically elite team, you will operate with high ownership, influence system design decisions, and directly impact platform architecture. This position is ideal for engineers comfortable building production-grade systems that process vast volumes of data under strict latency and reliability constraints.
