Attributes We Value
We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you’re motivated by our mission and operating principles. You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor.
You're humble and collaborative; turn zero‑to‑one ideas into real products, and you “get stuff done” end-to-end. You use AI to work smarter and solve problems faster. Here, you’ll tackle complex, high‑visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let’s build what’s next.
About the teamThe AI team is at the heart of our company’s data and AI strategy. We're building a world-class, customer-facing analytics product that turns data into business impact through AI. As a Senior AI Engineer, you'll build the agent systems at the heart of it — turning natural-language questions into trustworthy, accurate answers over business data that our customers can rely on.
This is a role for someone who pairs deep AI engineering with solid data engineering foundations — comfortable not just building agents, but understanding the data and metrics they reason over and what makes those answers reliable. You'll own meaningful problems end to end and set a high bar for technical quality.
We're committed to building a diverse and inclusive team, and we welcome applicants of all backgrounds. You don't need to meet every qualification to apply — if you're excited about this work and meet the essentials, we'd love to hear from you.
This role is based in Singapore.
What you'll doDesign, build, and ship AI agent applications and agent harnesses that answer business questions accurately over governed data.
Build core agent capabilities, including retrieval-augmented generation, natural-language-to-query, and tool or function calling.
Improve AI output quality through prompt and context engineering, evaluation benchmarks, guardrails, and ongoing quality measurement.
Partner on governed metrics, data models, and data pipelines so agents can reason over consistent, reliable, and secure business data.
Apply strong data governance and security practices, including the safe handling of sensitive data, to meet financial-services standards.
Contribute strong engineering judgment to technical design and review, and help raise the technical bar across the team.
