About The Role
As an Ex-founder (Technical), you’ll join Retell AI as a versatile, high-impact leader, shaping our AI voice platform in its earliest stages. Leveraging your startup experience, you’ll wear multiple hats—spanning product, engineering, and strategy—to drive innovation and execution. 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
Drive 0→1 initiatives, from ideation to execution, across product, engineering, or growth, adapting to the company’s most pressing needs. Build and iterate on core platform features, such as voice agent APIs, integrations, or developer tools, using languages like Python, JavaScript, or TypeScript. 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.
You Might Thrive If You
Have founded or co-founded a tech startup, navigating the 0→1 phase with hands-on technical and business responsibilities. Are a generalist with 2+ years of experience in software development (e.g., Python, JavaScript, TypeScript) and startup operations. Thrive in fast-paced, ambiguous environments, juggling multiple roles with grit and adaptability. Take ownership like a founder, moving fast and caring deeply about impact. Communicate clearly, aligning teams and making tough decisions with confidence. Learn quickly, embracing new challenges and tools to deliver results.
