Offensive Cyber Engineer
As an Offensive Cyber Engineer, you’ll dive deep into reverse engineering and vulnerability research on software and firmware, turning raw binaries into actionable intelligence and building exploits and capabilities that perform under real-world pressure. You will systematically deconstruct complex code to reveal its inner workings, uncover hidden behaviors, and identify exploitable flaws. You’ll also design and develop post-exploitation effects and implants that are robust, stealthy, and engineered to resist both forensic scrutiny and active countermeasures.
This is work that demands deep technical fluency, creative problem-solving, and the ability to build solutions that hold up when everything is on the line. If you’re motivated by conquering tough challenges and having your expertise translate into high-impact results, this role is for you!
