About the role

Responsibilities

  • Own product surfaces end-to-end, from identifying opportunities to shipping and iterating on solutions
  • Work directly with customers, CSMs, and GTM teams to deeply understand workflows and pain points
  • Design and build fullstack features that drive user impact and business outcomes
  • Rapidly prototype and test new ideas, especially in ambiguous or zero-to-one spaces
  • Help define how AI agents behave, reason, and deliver value in real-world workflows
  • Collaborate closely with design, product, and engineering to shape roadmap and prioritization
  • Translate insights from user behavior, customer conversations, and data into product improvements
  • Think beyond individual features and help shape product architecture and long-term platform direction
  • Push ideas into reality quickly instead of over-optimizing in planning phases

Requirements

  • 3+ years of experience as a software engineer, product engineer, or in a product-focused engineering role
  • Strong fullstack foundation, especially with Typescript, React, NextJS, and NodeJS
  • Track record of owning products or systems from concept through launch
  • High agency — move things forward without waiting for direction
  • Strong product intuition and care for user experience and business impact
  • Comfort operating in ambiguity and figuring things out in real time
  • Bias toward building and prototyping over endless planning
  • Strong communication across engineering, product, GTM, and leadership
  • Excitement about AI-native workflows and the future of product creation

Nice-to-Haves

  • Experience working closely with customers or in customer-facing roles
  • Background in startups or zero-to-one product development
  • Experience with AI/LLMs, prompt design, or building AI-powered products
  • Heavy usage of tools like Cursor, Claude, Windsurf, v0, or similar in workflow
