Job description

About Dexmate

Dexmate is building the foundation for physical AI — combining a new generation of robots with a universal Physical AI OS, making robots as easy to build and deploy as software. Today, robotics is fragmented, slow, and closed: most builders are forced to reinvent the same stack again and again, and most ideas never make it past the prototype stage. We exist to change that. Our mission is to democratize robotics by lowering the barrier to entry, delivering a plug-and-play platform for developers, researchers, and enterprises, and cultivating an open ecosystem that accelerates the evolution of physical AI. If you want to help shape the next layer of human capability — and believe the future of robotics should be built together, not in isolation — we’d love to build it with you.

About the Role

We are looking for a sharp, proactive, and highly execution-oriented Executive Assistant to work closely with our CEO in a fast-paced robotics and AI startup. This role combines executive support, cross-functional coordination, and hands‑on execution. The ideal candidate learns quickly, exercises strong judgment, and is comfortable taking ownership in a dynamic environment.

Responsibilities

• Work closely with the CEO to drive priorities forward, coordinate across teams and external stakeholders, and ensure important initiatives receive timely follow-through.

• Own day-to-day executive support and coordination, helping the CEO stay organized and focused on the highest-priority work.

• Conduct research, synthesize information, prepare materials, and support decision-making and communications.

• Take ownership of special projects and operational tasks, independently driving them from request to completion.

• Support essential office and administrative operations as needed in a hands‑on startup environment.

• Leverage AI and automation to streamline workflows, reduce repetitive work, and improve operational efficiency.

Requirements

• 3–5 years of experience in executive support, business operations, consulting, startups, or another high‑intensity environment.

• Sharp, resourceful, and a fast learner, with strong judgment and problem-solving ability.

• Highly execution-oriented with strong ownership; able to turn loosely defined requests into concrete results.

• Excellent organization, communication, and stakeholder-management skills, with strong attention to detail.

• AI‑forward mindset, proactively using AI and automation to work smarter and improve processes.

• Comfortable with ambiguity, changing priorities, and the hands‑on nature of an early‑stage startup.
