As a Senior Prototyping and Integration Engineer , you’ll operate alongside, but outside, the standard product development cycle to rapidly create prototypes, proofs of concept, and innovative solutions that address high urgency or high risk needs. You’ll guide projects from early exploration through successful handoff into traditional workflows, blending technical engineering with project leadership. This role works across hardware and software integration, engages directly with vendors and contractors, and produces clear internal and external documentation that supports both engineering and market positioning. Success requires strong communication across all levels of the organization, the ability to navigate existing workflows without unnecessary disruption, and the maturity to build trust while driving change.

Ideal candidates bring a background in systems integration or product development, with deep knowledge of two-way radio technologies, including P25 and DMR systems, along with system administration experience, basic networking skills, and a history of working directly with Public Safety customers to design and implement complex solutions. You’ll frequently lead small, cross functional teams to research needs, define requirements, design and engineer solutions, and evaluate results. Experience with both hardware and software development is important, as is the ability to cultivate long term vendor relationships and creatively repurpose or adopt new technologies to meet evolving demands in the LMR industry. This role is hybrid, out of our Irving, TX location.
