[Hiring] Principal Engineer - Platform Modernisation @TechGrove by Banyan Software

Role Description

HWA International builds the trust accounting software that bank trust departments, credit unions, foundations, and family offices run their fiduciary operations on, and the platform is entering a significant modernization. This role leads the engineering of it: an AI-first effort to re-architect how the platform is built, deployed, and scaled, on a system that fiduciary accounts are administered through every day.

That is also what sets the bar. Accounting accuracy is the product, and a mis-posted transaction on a trust account is a client-loss event, so the engineering judgment we expect here is high.

This is a build-heavy, high-ownership role at the technical center of the platform. You will own the cloud architecture, the delivery automation, the engineering standards, and the technical execution of the modernization that carries the platform through its next phase of growth.

You will work agentic-coding-first from day one. That is table stakes here, not a bonus: you use agentic tools to deliver well beyond traditional hand-coding throughput, and you read, validate, and stand behind everything that ships.

This role builds the new platform rather than maintaining the old one. You will not work in the legacy application stack day to day, but you will use agentic tools to read it, map it, and understand its behavior deeply, and you will test the new platform against it to prove that every calculation comes out the same or better.

The modernization runs in stages, so expect what you do day to day to evolve: the agentic-coding way of working is constant from the start, while the architecture, deployment model, and tooling change as the modernization progresses.

You report to the Chief Product and Technology Officer and partner closely with the development and operations leads. You will also work with and level up a small, distributed team of engineers.
