About the Role:
We are seeking a capable and motivated Senior Full-Stack Developer to join our core engineering team and help evolve Gallantree’s cloud-based commercial lending and securities platform. This is a hands-on role suited to someone with solid experience across both front-end and back-end technologies who is ready to contribute meaningfully to a modern, fast-moving product environment.

You’ll be involved in developing user interfaces, APIs, automation workflows, and integrations across the platform. Working closely with the business and engineering leads, you’ll help translate complex financial workflows into clean, scalable, and efficient technology.

This role is ideal for someone who enjoys working in agile, growth-stage environments, where ownership, initiative, and continuous learning are encouraged.

This is an exciting time to join the company as the growth phase will catapult Gallantree into becoming a leader of the financial services community in APAC. Experience in financial services or structured finance is a plus, but not required—curiosity and technical versatility are more important. Our culture is one whereby the engineering team have a detailed understanding for the structure of the credit market, and are integrated into the entire operational functionality of the team from loan origination to partnerships to institutional reporting.

You’ll join and compliment a small, yet highly capable and efficient engineering and platform team, where everyone acts like a generalist, yet has specific skills and experiences they bring to the team. The vision for the engineering team is to be a small, nimble and highly effective team that can do the work of a team of many.
