  • Collaborate Across Disciplines: Partner closely with cross-functional teams including operators, analysts, and external development shops to translate mission needs into robust software requirements.
  • Consult & Guide: Serve as a trusted technical advisor, guiding customers on operational direction and the deployment of various software products.
  • Uphold Excellence: Participate in collaborative peer code reviews to ensure the highest standards of software reliability and security.

Qualifications

  • Experience:
    • 12 or more years of software engineering experience with a Bachelor’s degree.
    • Or 10 or more years of experience with a Master’s degree.
    • Or 16 or more years of experience (substituting years of additional software engineering experience in place of a Bachelor's degree).
  • Core Technical Expertise: Proven, hands-on experience in Reverse Engineering.
  • Programming Proficiency: Strong development skills in C, C++, and Python.
  • Collaboration & Integration: Demonstrated ability to coordinate with cross-functional teams (analysts, operators, developers) to deliver holistic software solutions.
  • Lifecycle Support: Experience supporting and maintaining fielded software systems in active environments.
  • Modern Tooling: Familiarity with version control systems (Git, Subversion) and the Atlassian suite (Jira, Confluence, Bamboo).
  • All applicants must currently reside in the United States
