The Opportunity: We are seeking a
Senior Embedded Software Engineer
with deep expertise in embedded systems, reverse engineering, and cybersecurity. This role is ideal for someone who thrives on
technical ambiguity , enjoys uncovering how complex systems really work, and excels in low-level software and hardware analysis. You’ll play a key role in evaluating security and robustness of proprietary embedded systems—developing custom tools, uncovering vulnerabilities, and contributing directly to national cybersecurity efforts.
Challenging, impactful work at the intersection of embedded systems, telecom, and cybersecurity. A technically driven environment that encourages innovation and deep technical exploration. Opportunities to publish research, present findings, or contribute to classified mission success. A team culture that values technical mastery, curiosity, and mentorship. Support for continued learning, certifications, and reverse engineering challenges.
Responsibilities:
Reverse engineer embedded firmware, device drivers, and proprietary telecom systems to identify undocumented functionality and potential security issues. Perform firmware extraction, binary diffing, static and dynamic analysis, and hardware-assisted debugging. Collaborate with hardware engineers to access debug interfaces (e.g., JTAG, SWD), extract flash images, and inspect hardware state. Develop custom tools and scripts (e.g., in Python3) to automate analysis workflows such as firmware unpacking, protocol decoding, and memory analysis. Investigate edge-case behaviors, error-handling routines, and low-level system initialization logic to reveal attack surfaces. Document findings clearly and translate technical complexity into actionable reports for security and engineering teams.
Qualifications:
Required:
An active
Top Secret clearance . 8+ years of professional experience in
embedded software development
