Description

Software Reverse Engineer – Job Description

Who We Are
Kudu Dynamics is Leidos Owned Company, forged out of a decade of experience in computer network operations and staffed with talent who have built, overseen, and enhanced capabilities throughout the entire USG arsenal. Our team of hackers and engineers have experience spanning centuries of research, development, and operations missions - across desktop, mobile, IoT, and embedded platforms. Kudu Dynamics, a Leidos company is uniquely qualified to anticipate tomorrow’s threats and build the next generation of capabilities.

Job Description:
Our team is working to develop novel and innovative cybersecurity capabilities. The Software Engineer will be part of a team developing a computer exploitation framework. Working closely with reverse engineers and vulnerability researchers, this position will develop a usable framework for software exploitation running in a highly constrained environment. Particular emphasis will be on building testable exploit chains, working to ensure reliability even in an unknown environment. It's the kind of job where you get to poke holes in real systems and look for things that make you stop and go "huh, that's weird…" This role will go from initial analysis of target systems all the way up to testing for reliability for mission-critical scenarios.

Required Qualifications:

A U.S. citizen with an active Top Secret security clearance with CI Polygraph
Expertise in C/C++ (C Preferred).
Knowledge of data structures, performance optimization / tuning, multi-threading.
Expertise in at least one scripting language (Python preferred).

Key Responsibilities:

Taking Proof of Concept vulnerabilities and extending them into robust, reliable exploits.
Maintaining a CI/CD pipeline for testing framework plugins.
Extending framework features as needed.
Working with vulnerability researchers to integrate proof of concepts into the framework.

Preferred Qualifications:

Experience with one or more assembly languages (x86, MIPS, ARM, etc).
Experience with hardware reverse engineering.
Experience with real-time embedded systems.
Experience with signal processing.

We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.

Original Posting:

March 17, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Securing Your Data

Beware of fake employment opportunities using Leidos’ name. Leidos will never ask you to provide payment-related information during any part of the employment application process (i.e., ask you for money), nor will Leidos ever advance money as part of the hiring process (i.e., send you a check or money order before doing any work). Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at [email protected].

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission.

Commitment to Non-Discrimination

All qualified applicants will receive consideration for employment without regard to sex, race, ethnicity, age, national origin, citizenship, religion, physical or mental disability, medical condition, genetic information, pregnancy, family structure, marital status, ancestry, domestic partner status, sexual orientation, gender identity or expression, veteran or military status, or any other basis prohibited by law.
