About this opportunity

The Principal Backend Engineer is the most senior individual contributor on our backend engineering team — the person others go to when a problem is hard, a decision is consequential, or a system needs to be built right the first time. This is not a people-management role, but it is a leadership role: you set the technical direction for our backend systems, raise the engineering bar across teams, and solve problems that cut across products and disciplines.

Our backend is built primarily on Ruby on Rails. You’ll own the architecture, standards, and long-term health of those systems while staying hands-on with production code. You’re also an engineer who has figured out how to get great results from AI tooling, and you bring that leverage to everything you do — and help the engineers around you do the same.

You’ll report to the SVP of Technology and work closely with product, data, and platform teams. This is a high-ownership role for someone who leads through expertise and trust rather than title.

In your first year, you've succeeded when the architecture is documented and actively owned, the backend architecture roadmap is real and being executed, and the engineers around you are making harder technical decisions with more confidence — with or without you in the room.

You must reside in one of these US states: AZ, CO, FL, GA, IL, IN, KY, MA, MD, MI, MN, NC, NV, OR, PA, RI, TX, VA, VT, WI, or one of these provinces in Canada: Ontario
