Countermeasure Engineer (CEMA)
About The Position
Sweep is building the defense layer for the AI age, focusing on ensuring intelligent machines and devices remain aligned with human intent in the physical world. The company deploys its solutions with high-stakes teams globally, including Olympic delegations, F1 paddocks, and government officials, to gather insights that form the foundation of a civilization-defining capability. Sweep is a small, talent-dense team that values high ownership, velocity, and a low ego approach. This specific role is for the first dedicated Countermeasure Engineer, operating across global deployments. The position involves identifying cyber-physical threats in real-world environments where conditions are uncertain and decisions are critical. The engineer will be responsible for turning field interactions into system learning to improve future deployments and will gain pre-Series A ownership as one of the first 10 engineers.
