About the role [The seniority/title is determined by job-related skills, experience, and evaluation after the interview.] We’re hiring Product Builders to shape the future of marketing for agents — where AI agents are no longer tools, but active participants in how products are built, decisions are made, and value is delivered. AI agents are fundamentally reshaping: how products are built (AI-native, faster, more iterative) how marketing flows work (agent-driven discovery, decisioning, and execution) how brands and customers communicate (from campaigns → conversations → autonomous interactions) This shift unlocks a new wave of opportunities — to redesign workflows, reimagine user experiences, and build entirely new product categories. This is not a traditional PM / designer / engineer / GTM role. You’ll operate as a builder at the frontier, using vibe coding, AI tools, and rapid prototyping to explore and ship products in this emerging space. You won’t just define what to build — you’ll build, test, and evolve it. What you’ll do Build, not just define Design and ship products — where agents discover, decide, and act on behalf of users. Ship fast, learn fast — iterate based on simulation or real usage. Own problems end-to-end Identify meaningful problems worth solving (clear “why this matters”). Drive from discovery → prototype → launch → iteration → scale. Operate with high agency Don’t wait for perfect clarity — create momentum, test hypotheses, and move forward. Take ownership of outcomes, not just outputs. Redesign how brands and customers interact Explore new interaction models: agent-to-agent, human-in-the-loop, and autonomous workflows. Reimagine marketing workflows as agent-driven systems, not static funnels. Focus on what truly matters Identify the core 1–3 things that make the product valuable, and execute them exceptionally well. Avoid overbuilding — prioritize signal over noise. Collaborate to ship impact Work closely with engineering, design, data, and GTM as co-creators. Continuously refine based on real-world feedback and data. What we’re looking for We’re looking for experienced, high-agency product builders who thrive in new, undefined spaces. Core traits Builder mindset: you ship, iterate, and learn quickly. High agency: you don’t wait — you create momentum. Strong product taste: you know what good looks like and push toward it. Experience 3–8+ years in product, engineering, startup, or builder roles. Experience shipping products end-to-end (0→1 or 1→n) with multiple showcases, with learning and problems to share. Exposure to AI-native products, LLMs, or automation is required. Skills Comfortable operating in ambiguity and fast-changing environments. Hands-on with prototyping (no-code, low-code, or code). Strong prioritization and product judgment. Mindset You believe the future is being built now — and you want to build it. You learn by doing, not waiting. You care about real customer impact. Bonus points Experience with AI agents, agent workflows, or automation systems Familiarity with marketing automation, CRM, or customer engagement platforms Experience with building AI products Background in startups or 0→1 product environments Technical background (engineering, data, etc.) Why join us? We’re at the start of a major shift: From marketing to users → marketing for agents. The way products are built, how decisions are made,
