Executive Assistant, Technical Executive Leadership About You and The Role Zipline is looking for an exceptional Executive Assistant to support Jo Mardall, our Chief Hardware Officer, and CJ Moore, our Head of Autonomy. Together, Jo and CJ lead some of the most technically complex and operationally critical work at Zipline: aircraft reliability, hardware execution, flight software, autonomy, release readiness, fleet health, and the systems that allow Zipline to scale safely. This is not a traditional administrative support role. You will sit close to the technical operating heartbeat of the company, helping two senior leaders stay focused, prepared, and effective across a fast-moving mix of engineering reviews, fleet health forums, release decisions, incident follow-ups, recruiting, executive discussions, and cross-functional escalations. The right person for this role is highly organized, calm under pressure, technically curious, and comfortable operating in ambiguity. You do not need to be an engineer, but you do need to be able to follow technical conversations well enough to understand what matters, who owns what, what needs to happen next, and when something needs to be escalated. You will be trusted with sensitive company, technical, people, and operational information. You'll need excellent judgment, strong written communication, crisp follow-through, and the confidence to work across senior executives, engineers, program managers, operations leaders, recruiting, People Partners, and field teams. This role is based at our South San Francisco, CA headquarters.
