Overview

Echelon Services, LLC is seeking a hands-on Cyber Developer / Vulnerability Researcher to support the Naval Information Warfare Center Atlantic (NIWC) Rapid Capability Office (RCO) Strike Team ACE, Advanced Cyber Effects. This is not a traditional cybersecurity compliance or policy role. This position is focused on offensive cyber capability research and development in support of mission objectives. The selected candidate will work with a dedicated technical team to identify critical vulnerabilities, reverse engineer systems and software, and develop custom cyber tools to support operational needs.

This role is ideal for a developer who enjoys solving complex technical problems, understanding how systems work, and finding creative ways to identify and exploit weaknesses. The position requires strong hands-on-keyboard technical ability, curiosity, and a willingness to work on challenging offensive cyber problems in a collaborative mission environment.

Echelon is seeking candidates with skillsets aligned to two mission areas:

Vulnerability Research

Cyber Development

Both areas require similar technical experience and will support cyber capability research and development for NIWC Atlantic.

The Cyber Developer / Vulnerability Researcher will support cyber capability research and development activities, including:

Conducting vulnerability research across a range of targets, including web applications, software, systems, and embedded technologies.
