## Job Description

## Responsibilities

- 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

- 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

- 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
