Staff Electrical Engineer

HEN Technologies is a purpose-driven organization pioneering advanced tools for both wildland and structural firefighting. Leveraging fluid dynamics, thermal science, and cutting-edge mechatronics, we are developing a new generation of fire-suppression technologies. Our commitment to innovation has earned recognition and support from the National Science Foundation, and we are expanding our engineering team to advance our mission.

We are seeking a Staff Electrical Engineer with deep expertise in power electronics, hardware system integration, and mixed-signal design to join our small but rapidly scaling product development team. This role is perfect for a highly technical engineer who enjoys owning entire electrical subsystems—from power architecture definition through schematic capture, PCB layout, bring-up, EMC validation, and testing.

You will collaborate closely with mechanical, software, and manufacturing teams to define power architectures, rapidly prototype hardware, and deliver robust, field-ready electronics for demanding firefighting environments. This is a hands-on, high-impact position with the opportunity to shape core product platforms.

• Define product-level electrical and power architectures, including power budgets, system interfaces, and safety requirements.
• Translate high-level concepts into detailed specifications, schematics, and testable requirements.
• Drive cross-functional technical alignment and design decisions.
  

• Design mixed-signal, digital, and analog circuitry including power stages, sensor interfaces, and control electronics.
• Own schematic capture and PCB layout (must-have) using industry-standard tools.
• Select components, perform derating analyses, review designs, and ensure reliability under harsh conditions.
  

• Design, simulate, and test DC-DC converters, motor drivers, power distribution networks, high-current switching stages, and protection circuitry.
• Define and validate power architectures for electromechanical systems.
• Coordinate closely with mechanical engineering on thermal and packaging constraints.
  

• Integrate commercial off-the-shelf wireless modules to support WiFi, Bluetooth, and cellular wireless technologies
• Select antenna options
  

• Bring up and debug new hardware; perform root cause analysis of electrical issues.
• Perform EMC debugging and mitigation, ensuring compliance with regulatory and internal standards.
• Integrate electronics with firmware, sensors, actuators, and mechanical assemblies.
• Develop test plans, fixtures, and validation protocols.
• Support product verification, field testing, and troubleshooting.
  

• Maintain accurate designs, BOMs, and revision control.
• Lead design reviews and mentor junior engineers or technicians.
• Collaborate with manufacturing on DFM, DFT, and NPI activities.
  

• Bachelor’s Degree (or higher) in Electrical Engineering or a related field.
• 8 years of relevant experience designing production-quality hardware.
• Strong experience with:
• Power electronics: DC-DC converters, motor drives, power protection & distribution.
• Mixed-signal design with 32-bit microcontrollers.
• Op-amp circuits, sensor conditioning, USB-C Power Delivery (PD).
• Hardware bring-up, deep electrical debugging, and EMC debugging/mitigation.
• Schematic capture and PCB layout using tools such as Altium Designer.
• Strong hands-on lab skills and experience with oscilloscopes, logic analyzers, multimeters, and JTAG/SWD debuggers.
• Comfortable turning ambiguous requirements into robust, field-ready hardware.
• Ability to work effectively in cross-functional environments.
  

• Advanced proficiency in Altium Designer.
• SPICE simulation and power-stage modeling.
• Experience designing for ruggedized or safety-critical environments.
• Embedded C/C or Python for test automation or firmware interaction.
• Expertise in thermal design, EMI/EMC compliance, or regulatory assessments.
• RF/Wireless integration experience

Base Salary range for this role will be $140k to $190k equity benefits. Individual compensation is determined by skills, qualifications, experience.
