Senior / Staff Product Engineer

Job description

About Passionfroot Creator-led growth is one of the fastest-growing channels in B2B—and we’re building the infrastructure behind it.

You’ll work closely with the founders, design, and customers to take important problems from early exploration to shipped product. We’re a team of six engineers, and staying small is deliberate. It means you can have an idea on Monday and have customers using it by Thursday—without layers of sprint ceremonies or alignment meetings in between. The flip side is real ownership: you need to exercise strong judgment, communicate your decisions, and think through their consequences rather than wait for someone else to catch them.
