Senior / Staff Product Engineer

About the role

About Passionfroot Creator-led growth is one of the fastest-growing channels in B2B—and we’re building the infrastructure behind it. Passionfroot is the leading platform where modern companies scale creator-led growth, and where top creators manage and monetize brand partnerships. Our customers include some of the most ambitious, fastest-moving companies in the world—Replit, HubSpot, Figma, Cursor, Gamma, Attio, Intercom, and ElevenLabs. We help them run high-impact creator programs across LinkedIn, YouTube, newsletters, and more. We're growing 13x in revenue year over year, profitable, and just closed our Series A round! We are backed by leading investors including Insight Partners, Creandum, Supernode and founders and operators from Cursor, Anthropic, n8n and more. We're expanding fast across New York, Europe, and Brazil - and we're just getting started. We’re still a small team, which means the people who join now will have an outsized influence on the product, the engineering culture, and the company we become. About the role We’re looking for a Senior or Staff Product Engineer to help build the next generation of Passionfroot. You’ll work across the full stack on both our core platform and Zest, our AI Campaign Manager for creator marketing. That could mean designing a new workflow for managing creator campaigns, making collaboration data feel instant, or turning models, search, and product context into a reliable AI experience that customers can trust. We don’t separate “AI engineering” from “product engineering.” AI is becoming part of how the product works, but great product fundamentals still matter: understanding the user, shaping the problem, choosing the right architecture, building a thoughtful experience, and operating it reliably in production. 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. What you’ll do Own meaningful product areas from problem definition through architecture, implementation, launch, and iteration. Build customer-facing features across our marketplace, campaign management, collaboration, payments, analytics, and creator workflows. Help make Zest an indispensable part of how modern companies run creator-led growth. Turn foundation models into structured, reliable product experiences—not just impressive prototypes. Work on intelligent workflows involving agents, tools, retrieval, search, recommendations, and generated interfaces. Develop the evaluations, observability, and feedback loops needed to understand whether AI features are genuinely useful. Work closely with design to create experiences that are fast, intuitive, and polished. Talk directly with customers and translate ambiguous needs into simple product decisions. Make pragmatic architectural choices that balance speed, quality, maintainability, and performance. Improve the systems and engineering practices that help a small team ship reliably at high velocity. At Staff level, provide technical direction across projects, raise the engineering bar, and help other engineers make better decisions. What we’re looking for Significant experience building and shipping high-quality, customer-facing software. 5+ years is a useful guide, but the scope and quality of your work matter more than the number. Strong TypeScript and React fundamentals, with experience working across the full stack. A track record of independently driving complex features or products from an ambiguous starting point to measurable customer impact. When you encounter a blocker, you in
