About the Role
Join Factorial as a Product Engineer to help redefine how AI powers the future of Business Management software. We want engineers who treat AI as central to their craft, who prefer building and shipping over endless debates, and who care about measurable impact from problem definition to delivery. This is not a maintenance role — the domain is expanding and there is real engineering work to do in AI-driven finance. What You'll Do
-
Define problems and design AI-powered features in the Finance domain, from ideation through to measuring the impact of shipped work.
-
Build and ship end-to-end solutions, owning the lifecycle beyond just writing code for tickets.
-
Contribute to agentic workflows, LLM-integrated features, and probabilistic systems built on our Rails/React stack.
-
Collaborate with Factorial’s Engineering team (200+ engineers) to deliver scalable, reliable AI-driven solutions that matter to thousands of companies. What We're Looking For
-
A passion for making AI central to the product and for shipping impactful features, not just writing code.
-
Curiosity about why a feature exists and how it helps users, not only how to implement it.
-
Comfort with a fast-paced, expanding domain and a preference for real engineering work over maintenance.
-
An ownership mindset: involved from problem definition through to measuring impact.
-
A collaborative mindset and ability to operate in a large, cross-functional engineering organization. Nice to Have
-
Experience with Ruby on Rails and React (our core stack).
-
Interest in agentic workflows, LLM-integrated features, or probabilistic systems.
