# Countermeasure Engineer (CEMA)

> Sweep360 · New York, United States · Full-time · Posted 2026-04-21

**Salary:** USD 170,000–200,000

**Workplace:** on_site

**Department:** Engineering

## Description

**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.
