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. Responsibilities include:

• Owning meaningful product areas from problem definition through architecture, implementation, launch, and iteration.
• Building customer-facing features across our marketplace, campaign management, collaboration, payments, analytics, and creator workflows.
• Helping make Zest an indispensable part of how modern companies run creator-led growth.
• Turning foundation models into structured, reliable product experiences—not just impressive prototypes.
• Working on intelligent workflows involving agents, tools, retrieval, search, recommendations, and generated interfaces.
• Developing the evaluations, observability, and feedback loops needed to understand whether AI features are genuinely useful.
• Working closely with design to create experiences that are fast, intuitive, and polished.
• Talking directly with customers and translating ambiguous needs into simple product decisions.
• Making pragmatic architectural choices that balance speed, quality, maintainability, and performance.
• Improving the systems and engineering practices that help a small team ship reliably at high velocity.
• At Staff level, providing technical direction across projects, raising the engineering bar, and helping other engineers make better decisions.

Qualifications

• Significant experience building and shipping high-quality, customer-facing software (5+ years is a useful guide).
• 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.
• Strong product and technical judgment.
• Experience building with LLMs or other applied AI systems in production.
• An understanding of the challenges behind reliable AI products.
• Clear, proactive communication and the ability to collaborate effectively in a remote environment.
• Care for software craftsmanship without losing sight of momentum and customer outcomes.

Requirements

• Developed a deep understanding of creator-led growth and the problems our customers face.
• Taken ownership of a major product or technical area with limited oversight.
• Improved how we build, evaluate, and operate AI-powered functionality.
• Earned the trust of the team through reliable execution and clear communication.
• Helped us make better product and technical decisions beyond your immediate projects.

Benefits

• Competitive salary and equity in a Series A company.
• Remote-first work with the option to work together in Berlin if you are local.

• 25 days of paid vacation, plus local public holidays.
• Regular team events and off-sites—past destinations include Mallorca, Barcelona, the South of France, Berlin, and the Baltic Sea.
