Job Description

We need someone who can get their hands dirty with a complex communications system, setting it up, testing it, and teaching others how to use it. You'll be working in a fast‑moving environment where you're constantly integrating new tech (both hardware and software) while keeping everything running smoothly. Think of it as being the person who makes sure all the pieces work together and then shows the end users how to use them in the real world. A big part of this job is teaching. You'll be leading both classroom sessions and hands‑on training, breaking down complicated technical stuff into language people can understand and use. We're looking for someone who can read the room, adjust on the fly based on who they're teaching, and make sure the knowledge sticks. You'll also be working closely with design teams to stay current on system updates and incorporate feedback into your training materials, all while troubleshooting issues and keeping operations running smoothly. If you've served in the military or worked in government, you already have a lot of what we need. Your experience training teams on new equipment translates directly into this role. You know how to diagnose problems quickly and find solutions when things go sideways, which is essential here. You're used to coordinating with different units, contractors, and stakeholders, which is the same kind of collaboration you'll do with our cross‑functional teams. Whether you've briefed officers or trained junior personnel, you know how to adjust your communication style to different audiences and technical skill levels. Maintaining operational readiness and keeping systems mission‑ready is second nature to you, which is exactly what we need for managing our development and production environment. Your precision with SOPs and training materials is a huge advantage. Your ability to master complex systems quickly while staying calm under pressure makes you ideal fit for this position.

Essential Functions

• Set up, configure, and document hardware and software systems for testing, including loading both custom and commercial software onto multiple platforms.
• Develop and lead structured training sessions that help users understand and retain what they're learning.
• Build, configure, troubleshoot, and integrate new and existing hardware packages to roll out upgrades, deploy applications, and enhance system capabilities.
• Take full responsibility of the hardware configuration process, master the system inside and out, and train others to use it effectively.
• Support day‑to‑day training system operations and keep everything running smoothly.
• See training classes through from start to finish, making sure participants leave confident and capable.
• Travel occasionally to support training and system integration at different locations.

Qualifications

• Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.
• Active TS/SCI w/ Poly Clearance is required.

Preferred Additional Skills

• Solid understanding of engineering principles, particularly verification and validation processes.
• US Military Training Certifications are a big plus.
• Self‑starter who can work independently without needing constant direction.
• Comfortable working directly with customers and their leadership teams.
• Eager to learn through self‑study, hands‑on experience, and pick up knowledge from teammates.
• Proven ability to lead small, diverse teams in fast‑paced environments while staying humble and collaborative.
• Strong communicator in both speaking and writing, with solid skills in MS Word and PowerPoint.
• Experience explaining complex technical topics to different audiences, whether that’s fellow engineers, program managers, or customer leadership.
• Proficient in developing and working with MS Excel spreadsheets and data.
• Train‑the‑trainer certifications are highly valued.
