## Job Description

## Responsibilities
- 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.

- Systematize patterns into repeatable frameworks across environments.
- Close the loop by feeding interactions back into system learning.
- Partner with RF, hardware, and product teams.

## Requirements
- 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).

## Nice-to-Haves
- 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.

## Compensation
- Base salary up to $200,000, depending on qualifications, experience, and impact.
