Applicants should have a high school diploma or GED, strong organizational and communication skills, attention to detail, multitasking ability, willingness to learn, and the ability to work onsite.

Own the payload engineering model through requirements, design, build, integration, testing, qualification, and documentation. Integrate optical, LiDAR, radar, effector, avionics, and software systems; perform optical alignment, hardware-in-the-loop testing, environmental qualification, and ground demonstrations. Maintain verification matrices, risk registers, design review packages, test reports, and customer-facing qualification documentation while supporting autonomous sensing and pointing capabilities for space systems.

Build and maintain consumer iOS and React Native experiences for health results, biomarker data, chat, and other member journeys. Own mobile architecture, native integrations, reusable components, performance, accessibility, testing, observability, reliability, and App Store releases. Collaborate with product, design, clinical, web, and backend teams on clear health experiences, shared data contracts, and cross-platform development patterns. This is an in-person San Francisco role with substantial ownership in a small startup team.

Build and deploy autonomous AI agents for enterprise customers. Own implementations end to end, including understanding customer workflows, developing integrations, shipping production agents and evaluations, and engineering systems for continuous improvement. Translate customer feedback and recurring deployment challenges into platform capabilities and product direction. Collaborate directly with customers and founders in a fast-paced, in-person startup environment.

Develop technical specifications, submittals, and reusable documentation for low- and medium-voltage switchgear and power distribution equipment. Translate engineering specifications into clear materials for review, approval, and installation; collaborate with engineers and SMEs to validate technical details; and organize reference information into a documentation library. The role supports switchgear, PDUs, RPPs, and related 480V+ systems, using AI tools such as Claude to accelerate drafting while maintaining accuracy.

Builds simulation infrastructure and software-in-the-loop sensor simulation products that help customers test and validate autonomous driving, drone delivery, eVTOL, robotics, and other physical AI systems safely at scale.
