Who Are They
Our Client is based in central Maryland. Their mission is to make the connected world more safe and more secure for individuals, businesses, and governments. They've advanced the bounds of information theory, secured independent validation and patents, and built systems and networks that are revolutionizing secure communications.


Their Values

They believe that privacy is a right.

They endeavor to advance the boundaries of science.

They value personal and professional integrity above all else.


Why Them?

Our client thrives on solving complex problems. They think deeply about simple, foundational challenges in systems, signals, and science. They are essentially a deep-tech startup: our solutions aren't the "next best things" in security or communications; they're advances that were not considered possible, or practical… but they have achieved them, built the proofs, and are keen to press their advantage.

They are looking for motivated professionals who bring something different to the table, who come with curiosity and talent, and who represent fresh ideas and perspectives. Lastly, and most importantly: they are an equal opportunity employer who actively celebrates diversity and who is committed to creating an inclusive environment for all employees.

In addition to their unique culture and mission, they offer the following benefits:

  • 100% Employer-funded Carefirst Open PPO
  • Employer-funded Health Savings Account
  • 401(k) plan with Employer contributions
  • Employee Incentive Plan
  • All Federal Holidays and Generous PTO!
