Red 6 is an augmented reality startup developing synthetic air combat training systems for military pilots. The ATARS product overlays realistic 3D adversaries, wingmen, terrain, and tankers into pilots' real-time views during actual flight, replacing costly legacy training methods with immersive, repeatable, scalable preparation. As Principal Electrical Engineer, you will own the electrical architecture for next-generation airborne AR hardware—from blank-page design through prototype, military qualification (MIL-STD-461 EMI/EMC and MIL-STD-810 environmental), manufacturing, and flight deployment. You will lead the full lifecycle of real-time embedded systems that fly in actual military aircraft. Key responsibilities include: - Defining next-generation electrical architecture and subsystem integration strategies for mission-critical airborne systems - Conducting trade studies, prototype validation, and design optimization across power, signal integrity, and environmental robustness - Designing electrical interfaces, power architectures, PCBA layouts, and flex circuits to military standards - Collaborating with systems, optics, software, and flight test teams on proposals, budgets, and schedules - Mentoring electrical engineers and establishing design standards and best practices for a growing EE organization - Hands-on lab work with oscilloscopes, power supplies, spectrum analyzers, and design simulation tools - Planning, tracking, and communicating design progress against cost and schedule constraints Your work directly impacts warfighter readiness and preparation for real-world missions. You will have significant influence over product direction and technical decisions in a high-growth, early-stage company positioned to lead the defense AR industry. REQUIREMENTS: - BS in Electrical Engineering or related technical field - 12+ years developing complex electrical systems for aerospace, defense, or other high-reliability applications (or equivalent education/experience mix) - 5+ years leading electrical architecture for complex airborne or mission-critical systems - Deep expertise in subsystem electrical architecture, mission systems integration, and real-time embedded hardware - Hands-on experience defining electrical interfaces, power architectures, integration strategies, PCBA and flex circuit design - Proven track record designing to MIL-STD-461 (EMI/EMC) and MIL-STD-810 (environmental) standards - Experience leading trade studies, architecture reviews, and multidisciplinary teams through complex engineering problems - Proficiency with lab instrumentation (oscilloscopes, power supplies, spectrum analyzers) - Ability to plan, track, and communicate design work against cost and schedule - Strong communication and leadership skills that elevate engineers around you - U.S. citizenship and ability to obtain/maintain DoD Secret clearance IDEAL QUALIFICATIONS: - Hands-on military flight hardware development experience, including qualification, airworthiness certification, and flight deployment on military aircraft - MS or PhD in Electrical Engineering - Experience with FPGAs, SoCs, SOMs, GPUs, displays, sensors, and test systems - PCBA design and simulation with Altium - High-speed design expertise (DDR3/DDR4, PCIe 3.0/4.0, DisplayPort, USB 3.0, Ethernet, VPX, rugged computing) - Knowledge of avionics protocols (MIL-STD-1553, ARINC 429, CAN, deterministic architectures) - Systems engineering per ISO/IEEE 15288 and product development lifecycle experience - Demonstrated ability to lead cross-functional teams solving hard problems and mentor staff - Sense of urgency, confidence, and personal accountability for on-time, high-quality delivery
