Senior Flight Control Software Engineer

About us:

Guardian Agriculture is developing large multicopters for applying agricultural chemicals to high-value crops. Relative to existing plane- and helicopter-based crop spraying solutions, our systems radically improve precision and safety while reducing chemical use, reducing impact on pollinating insects, and minimizing opportunities for organisms to acquire chemical resistance.

Guardian is a small, multi-disciplinary team of talented engineers, technicians, and operators who prioritize high reliability product and service design over exploratory R&D. We are a hands-on team and split our time between development work, system testing, and field deployments. We value safety, thoughtful design, teamwork, and a growth mindset as we scale the organization and build an autonomous system that farmers can trust.
