Back Office Engineer at Truss

In-person positions are available in San Francisco, or remote opportunities are offered for candidates in Canada. We do not hire remote employees in the US, only in Canada. Truss runs a custom-built back office that powers our reviews, case work, and risk decisions. It works — but most of it still runs through human review, and the volume is only going up. We're hiring a Back Office Engineer to change that. Your job is to build the automation layer on top of our back office. Most of the reviews and cases that run through it today shouldn't need a human. Your work will: automate the routine reviews end-to-end, build the systems that let us handle cases at the scale we're growing into, and design the architecture that catches fraud before it happens rather than after. This is a high-leverage applied AI role. The systems you build will run at high volume against real operational workloads, so quality, observability, and the right guardrails matter from day one. We want someone who can move fast, build things that hold up under scrutiny, and treat the back office as a serious engineering surface — not a backwater. You'll work directly with the founder. Truss is a small team — 11 people
