About Sentradel Over 90 percent of combat deaths in Ukraine are caused by small drones. In Colombia, over 100 military and police officers have been killed by cartel operated drones. Shahed drones hit civilian and military targets across the Middle East uncontested. Unjammable fiber optic and AI controlled drones are making the threat cheaper, faster, and harder to stop. This problem will only get worse. Sentradel is a defense startup in San Francisco building autonomous, low cost kinetic turret systems designed to defeat Group 1 (small FPV drones) and low flying Group 2 drone threats. We have shot down dozens of drones in live fire testing, have active Department of War agreements, commercial partnerships, and sales. How we work Full time, in person at our San Francisco office. We also travel and test frequently at our Nevada range, and across the US at demos with partners and customers. Job Overview We are seeking a mechanical engineer to join the team developing...
