At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

We build the most advanced technology solutions on, and off, Earth. Our products unfold the deepest mysteries of the Universe, vanish from radar, communicate when all else fails, and drive global security. We need good people to help those missions, and many more, be successful.

If you want to be a part of that, and have what it takes, you’re a unique breed. You’re the kind of person who can’t sleep when a problem is bugging you; to solve it you’ll teach yourself a new programming language, build your own frameworks, dismantle others’ tools to bend them to your will; you’ll want to share what you’ve learned because it’s just that cool.

Northrop Grumman is seeking creative, skilled and motivated Offensive Security professionals to join our Cyber Assessment Tiger Team (CATT) to conduct full-scope penetration testing to help find the holes in critical systems, products and networks before our adversaries can.

  • Develop exploits for disclosed and undisclosed vulnerabilities.
  • Prepare documentation, vetting, and weaponization of vulns for team use
  • Advise and contribute to the Blue Teamers’ design, development, and implementation of countermeasures.
  • Work with CATT teammates to develop tools and techniques that continually improve our effectiveness.

Basic Qualifications:

  • First and foremost: be passionate, curious, diligent, and hungry for knowledge.
  • Grasp security fundamentals and common vulnerabilities (e.g., OWASP Top Ten, MITRE ATT&CK) plus modern web app and enterprise app vulnerabilities.
  • Have a solid understanding of AWS IAM, Lambda, S3, EC2, REST, OAUTH, etc.
  • Be familiar with container solutions such as Docker, Kubernetes, App2Container, OpenShift, etc.
  • Have experience writing scripts and exploit code. If you can share some samples, or have public projects, even better.
  • Extensive technical computer/network knowledge and understanding of computer hardware, software, networks, communications, and connectivity.
  • Proficiency in both Linux/Unix and Windows operating systems
  • Experience conducting adversary emulation, including social engineering, server and client-side attacks, protocol subversion, physical access restrictions, web app and backend SQL exploitation, and remote C2.
  • Proficiency in multiple common programming languages such as C, C++, C#, Go, Python, Ruby, Bourne/Bash, PowerShell, Visual Basic, VBScript, PHP, JavaScript, HTML
  • Eligibility for a US security clearance

Preferred Qualifications:

  • Relevant certifications such as OSCP/OSWA, GPEN/GXPN
  • In depth understanding of layer 2-7 communication protocols, common encoding and encryption schemes and algorithms.
  • Experience countering Advanced Persistent Threat (APT) type threats to large enterprises (USG or commercial) - familiarity with techniques and tools employed.
  • Previous software development to support penetration testing including vuln dev, tool creation or modification, covert tunneling, scanning scripts, passive collection, reverse engineering, binary analysis, source code analysis, etc.
  • Prior experience with modern enterprise hybrid network architecture
  • Understanding of and experience either executing or defending against complex, targeted cyber threats to high-value systems and data.
