Our Rebellion:

Rebellion Defense builds mission-focused AI products for the defense and security of the United States, the United Kingdom, and our allies. We are a well capitalized, venture-backed technology company that creates software which transforms data into decision advantage.

Our people are passionate about creating a company where technologists empower our military and civil servants to solve some of the hardest problems in government. Rebellion Defense is driven by our mission — but a set of core values binds us together: we hire by them, operate through them, and uphold them in every decision we make for ourselves and for our customers.

Your Rebel Team:


The engineering team is focused on building powerful, automated products that apply artificial intelligence to analyze, secure, and transfer national security data to deliver decision advantage to our customers. Rebellion products are built to transform three critical national security challenges: How can the DoD/MoD better analyze the vast streams of data, better secure critical systems, and better share information across disparate systems to accelerate awareness and decision-making? 

This role reports to our Engineering Manager

How you’ll make a difference in this role:

We are looking to hire a Security Researcher who will create adversarial security testing capabilities as part of amazing solutions for the US Department of Defense and global allies. This Security Researcher role is part of the team developing our Secure product -- providing critical cybersecurity capabilities to protect our military network infrastructure from attacks.

The Security Researcher will research the activities of real-world adversaries in the cyber domain and develop capabilities and content that mirror them, in order to validate the security controls of our customers. 

What your mission is: 

  • Research the latest tactics, techniques, and procedures of adversaries within the cyber domain
  • Develop adversarial playbooks and exploits to test the defenses of our customers
  • Collaborate with software development teams to develop world-class adversarial security testing capabilities
  • Help protect the United States and its allies from sophisticated threats
  • Work with the latest tools, on well-resourced teams, on the leading edge of security research, in defense of national security

  • Are comfortable conducting code reviews in various programming languages.
  • Enjoy working as part of a cross-functional team.
  • Are capable of rapidly learning new technologies in unfamiliar environments.

The Nature of our Work: 

We are driving fast change to an extremely regulated industry. Many of the national security programs that are supported by Rebellion’s products operate in secure environments and access to those spaces and the data in them may require an active personnel security clearance. It is a requirement of this position that you are able to obtain and hold a personnel security clearance at the right level.
