Hermeus is a startup developing hypersonic aircraft to radically accelerate air travel. At Mach 5, more than twice the speed of the supersonic Concorde, passengers will be able to cross the Atlantic in 90 minutes. On the path to hypersonic passenger aircraft, Hermeus is partnering with government agencies including the US Air Force and NASA to develop a series of autonomous aircraft that derisk the technology and solve urgent national security challenges. These products provide the data and confidence necessary to certify, produce, operate, and maintain safe and comfortable commercial aircraft. Hypersonic aircraft have the potential to create trillions of dollars of new global economic growth per year, unlocking significant resources that can be utilized to solve the world’s greatest problems.
Hermeus seeking an Information Systems Security Engineer (ISSE). The role of the ISSE is to bridge the gap between high level security policies/requirements and technical/operational implementation of those requirements. Candidates should have in-depth understanding of the cybersecurity policies and procedures for government sector information systems and sufficient technical knowledge and experience to implement them.
