About the Role

You’ll collaborate closely with the founding team to tackle ambiguous challenges, build scalable solutions, and define the future of voice automation. This role offers unparalleled ownership and the chance to shape a category-leading product from the ground up.
Key Responsibilities

Collaborate with co-founders to define product strategy, prioritize roadmaps, and align on technical and business goals.
Tackle ambiguous problems, prototyping solutions and shipping production-ready systems under tight timelines.
Mentor early team members, fostering a culture of ownership, speed, and craft.
Translate customer and market feedback into actionable product improvements and strategic recommendations.
GTM / PLG Path

Thrive in fast-paced, ambiguous environments, juggling experiments in acquisition, activation, retention, and expansion.
