DoW SkillBridge Vulnerability Researcher; Cyber

Research Innovations, Inc. (RII) is breaking through the big, slow, status quo with transformative technology that fundamentally changes and improves the world. We develop cutting‑edge software for all levels of the government and military. Using agile development practices and user‑centered design, we create innovative software solutions for complex real‑world problems.

We are seeking a dedicated Vulnerability Research Skill Bridge candidate to join our Cyber Security team. In a Vulnerability Research Skill Bridge opportunity at RII, you will play a pivotal role in solving unique and challenging problems for our esteemed Defense and Homeland Security customers. This position requires a proactive mindset, deep technical expertise in vulnerability research, reverse engineering, and exploit mitigations/bypasses, and a drive to live one of our core values:
Get s#!t done
.

This position is specifically for members of the DoD who are transitioning back to civilian life and can take advantage of programs such as Skill Bridge. RII has strong connections to the military community, and we understand the transition to civilian life can be stressful—we will help you navigate those challenges. We are an approved DoD partner, and we have supported the transition of several active duty members to civilian roles, many of whom have been offered and accepted full‑time employment with RII at the completion of their Skillbridge.

During and after, RII provides an industry‑leading mentorship and training program to selected applicants, supporting challenging, real, mission‑oriented problems.

This position requires an active US Secret security clearance.
