Job Summary

The Principal Systems Engineer will lead the design, development, integration, and verification of advanced microelectronic and compute‑intensive hardware systems, with a primary focus on new development 3U VPX modules, high‑performance embedded computing platforms, and complex AI processing hardware. This role requires deep multidisciplinary engineering expertise, technical leadership, and experience architecting and maturing sophisticated electronic systems from concept through qualification.

The position is 100% onsite, located in Cape Canaveral, Florida.

Essential Duties/Responsibilities

• Lead R&D activities centered on next‑generation embedded computing architectures, including development of system specifications, ICDs, and test plans supporting high‑speed digital, RF, and mixed‑signal hardware.
• Drive the design, prototyping, and validation of microelectronic and PCB‑level hardware including 3U VPX modules, AI accelerator subsystems, and other mission‑critical compute elements.
• Collaborate closely with electrical, mechanical, software, and manufacturing teams to ensure seamless integration of high‑density digital systems, high‑speed interfaces, and complex power architectures.
• Troubleshoot and resolve issues across multi‑board assemblies, embedded processors, FPGA‑based designs, and custom electronics, applying rigorous analytical methods to mature concepts into production‑ready hardware.
• Provide expert guidance for hardware bring‑up, functional testing, debug, iterative redesign, and system‑level integration, including environmental qualification and performance characterization.
• Maintain comprehensive engineering documentation such as verification matrices, configuration management records, detailed test results, and full lifecycle development artifacts.
• Deliver clear and technically precise communication to internal engineering teams, external stakeholders, and mission partners to ensure alignment across rapid development cycles.
• Treat all coworkers with respect and dignity ensuring a collaborative culture is continually developed and maintained.
• Other duties as assigned**

Required Education and Experience

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Systems Engineering, or other related STEM field; equivalent experience considered.
