Countermeasure Engineer (CEMA)

Why Sweep

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.

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.
