Countermeasure Engineer (CEMA)

New York

**TL;DR --- We're building the defense layer for the AI age and are looking for a Countermeasure Engineer to operate in the field --- identifying cyber-physical threats, acting in real time, and turning those interactions into system learning that compounds globally.** *If you want to operate in environments where nothing is labeled, nothing is stable, and decisions matter immediately --- this is that role.* **Why Sweep?** As intelligent machines proliferate into every part of the physical world, we humans still lack a defense layer to ensure the systems and devices we rely on remain aligned with us. We're building that layer today by deploying alongside the world's highest-stakes teams --- Olympic delegations, F1 paddocks, halftime shows, global tours, studio productions, senior government officials, and executive protection units. What we learn there becomes the foundation for a civilization-defining capability. We're a small, talent-dense team with high ownership, high velocity, and low ego. We care deeply, move fast, and are here to build something that outlasts us. Together, we'll redefine cyber-physical security for the AI age. **What makes this role special?** * First dedicated Countermeasure Engineer operating across global deployments * Operate where cyber, physical, and environment collide * Make decisions under uncertainty and determine what actually matters * Turn field interactions into system learning that improves every deployment * Work in environments where precision and judgment matter * Gain pre-Series A ownership as one of the first 10 engineers **What we're looking for...** * 3-6 years operating in environments involving real-world cyber-physical risk (Wi-Fi, BLE, rogue access points, IoT, robotics, embedded systems) * Ability to reason across software, networks, hardware, and adversarial behavior * Comfortable acting under ambiguity and adapting quickly * Ability to identify and assess covert or non-obvious threats (e.g. hidden cameras, rogue sensors, embedded devices) * Strong engineering fluency (mobile, backend, data, or infra --- breadth over specialization) * Clear communicator --- translates chaotic observations into structured insight * U.S. Person status (export-controlled environments) **Bonus if you've...** * Work in elite sports, live production, national-level events, or SOF/IC environments * Hands-on with SDRs, packet capture, or technical counter-surveillance tools * Operated in forward-deployed or embedded roles * Built automation or workflows from real-world data * Thrived in an early-stage startup **What you'll do...** * Deploy globally for short, high-intensity engagements (:40-50% travel) * Work directly with teams on the ground in high-stakes environments * Identify and assess cyber-physical threats in the field * Act in real time to contain, remove, or mitigate threats * Convert countermeasures into clear, actionable guidance * Brief non-technical stakeholders clearly under pressure * Systematize patterns into repeatable frameworks across environments * Close the loop by feeding interactions back into system learning * Partner with RF, hardware, and product teams **How we select...** * Short application * 20-minute intro call * Technical deep-dive * Practical problem discussion * References and offer **Final facts.** Base salary up to $200,000, depending on qualifications, experience, and impact. Total compensation includes equity, premium insurance, 401(k), flexible PTO, and other individual benefits. You'll join us on-site at our HQ in New York City with occasional domestic and global deployments. **Apply. Make history. Build humanity's defense against machines.**
