Vertex in Indianapolis, IN is seeking a Principal Electrical Engineer to provide technical leadership in power conditioning, drive electronics, and advanced networked control architectures across ground industrial and vehicleclass systems. This growth position will define and standardize approaches for power conversion, battery charging, nonlinear load handling, digital I/O/COTS SBC integration, and CANbased control architectures (CAN 2.0/CAN FD) at the physical, logical, and application layers.

The Principal Electrical Engineer will lead electrical architecture for multiboard and multimodule systems, partition functions across CCAs and subsystems, and drive standards and best practices in power electronics, drive circuitry, digital I/O, and communication interfaces. The role includes architecting power systems, designing battery charger and energy storage systems, handling nonlinear loads and actuation drives, defining CANbased communication schemes, and guiding integration of SBCs and digital I/O/relay circuits. This engineer will serve as a principal technical authority, mentoring other engineers and influencing proposals and IRAD investments.

• Lead electrical architecture and design for power conditioning, drive electronics, and CANbased control subsystems across multiple programs.

• Define systemlevel power architectures, including AC/DC and DC/DC conversion, distribution, protection, and energy storage strategies.

• Architect and design battery charger systems and energy storage interfaces, including charging algorithms, protection, and diagnostics.

• Define and validate solutions for nonlinear loads (motor drives, pulsed loads, Class Dstyle power stages) to maintain power quality and system stability.

• Specify and oversee the design of regulated and unregulated DC/DC buck controllers, isolated topologies, and Hbridge/dual Hbridge drive stages.

• Define CANbased communication architectures, including physicallayer design, bus topologies, and applicationlayer messaging for control and diagnostics.

• Guide the integration of digital I/O, relay control, and COTS SBCs into power and control subsystems.

• Perform and review advanced simulations (SPICE/SIMetrix, MATLAB/Simulink, ANSYS SiWave, Keysight ADS or equivalent) for SI/PI, transient behavior, and power system performance; ensure correlation with test results.

• Lead and host design reviews, set analysis expectations, and approve critical component and topology decisions.

• Support and guide EMC/EMI and environmental qualification campaigns for power, drive, and communication subsystems.

• Mentor senior, midlevel, and junior engineers in power electronics, drive systems, CAN architectures, and advanced simulation methods.

• Contribute to and lead proposals, cost/schedule estimates, and IRAD planning in power, drives, and networked control.

Education & Experience

• Bachelor’s Degree in Electrical Engineering, Computer Engineering, or related STEM field; advanced degree strongly preferred.

• Minimum 12 years of professional electrical engineering experience, or 10+ years with a relevant Master’s degree (MSEE, MSCE, or similar).

• Demonstrated experience in:
• Power conditioning and conversion for ground industrial or vehicle systems (or analogous highreliability domains such as medical or space).
• Battery charger systems and energy storage architectures (charging algorithms, protection, stateofcharge/stateofhealth considerations).
• Handling nonlinear loads (e.g., motor drives, switchedmode loads, pulsed loads, Class Dstyle power stages) with appropriate power system design and protection.
• CAN bus architectures (CAN 2.0, CAN FD) including physicallayer design, protocol configuration, and applicationlayer messaging for control and diagnostics.
• Integration of digital I/O, relay control, and COTS single board computers into power and control subsystems.

Required Skills

• U.S. Citizen with ability to obtain and maintain a DoD Secret clearance.

• Expert proficiency in power electronics at board and subsystem levels (DC/DC converters, AC/DC conversion, battery interfaces, protection schemes, efficiency/thermal tradeoffs).

• Experience defining architecture, requirements, and design standards for power systems on ground platforms (industrial equipment, vehicles, or similar).

• Expertise in battery charger design (buck/boost and multistage charging, battery management, balancing, safety and compliance considerations).

• Deep understanding of nonlinear load behavior and its impact on power quality, stability, and reliability; ability to define and validate mitigation strategies.

• Experience with regulated and unregulated DC/DC buck controllers, isolated topologies, and Hbridge or dual Hbridge drive configurations for actuation, rotators, or power stages.

• Expertlevel proficiency in SPICE/SIMetrixclass simulation tools (e.g., LTSpice, SIMetrix/SIMPLIS); able to handle complex cases, perform advanced modeling of power and drive systems, and teach detailed use to other engineers.

• Proficiency in CAN physicallayer design (transceivers, termination, EMC/EMI considerations), bus topology, and signal integrity.

• Experience designing applicationlayer CAN messaging (diagnostics, control, safety) and integrating with embedded controllers or microcontrollers.

• Advanced proficiency with ECAD tools (e.g., Altium Designer) and associated workflows for complex board and systemlevel designs.

• Advanced use of simulation tools (SPICE, MATLAB/Simulink, ANSYS SiWave, Keysight ADS or equivalent) for SI/PI, transient, and power system analysis, with demonstrated modeltotest correlation.

• Strong background in EMI/EMC design and mitigation from concept through qualification for power, drive, and communication subsystems.

• Experience leading design reviews, defining analysis expectations, and ensuring robust documentation and configuration control.

• Ability to coordinate digital I/O, relay control, and SBC integration within broader power and control architectures.

• Operates with full autonomy; recognized as a principal technical authority for power, drive electronics, and CANbased architectures.

• Strong strategic thinking and decisionmaking; balances performance, cost, schedule, and risk across programs.

• Excellent communication skills in technical forums, executive briefings, and customer meetings.

• Proven leadership in crossfunctional settings; able to guide integrated product teams and influence program direction.

• Demonstrated ability to mentor senior, midlevel, and junior engineers and shape training, standards, and best practices across the electrical discipline.

Desired Skills
