• Somebody who absolutely thrives in a fast-moving, highly ambiguous environment
• Strong communication skills and a collaborative working style across engineering, product, marketing and design
• A hands-on mindset; you enjoy leading through building and do not want to move away from the technical work
• Somebody who takes full ownership, has little to no ego, and works well without a lot of structure
• Experience in healthcare, consumer health, direct-to-consumer and sensitive-data environments preferred
