Job description

About the Company:
We are a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms. With a world-class business development & leadership team already in place, we are well positioned to capitalize on already overwhelming demand.
Role Overview:
As an electrical engineer you will own the design, manufacturing, and integration of the embedded electronics that power our next-generation flight systems and ground support equipment. As an early to mid-career engineer, you will have an opportunity to build from fundamentals and learn a wide variety of skills in a startup environment.
You'll work closely with flight software, mechanical, GNC, and manufacturing teams to deliver best in-class electronic systems. If you want to build complex hardware on systems that matter-this role is for you.
Key Responsibilities:
  • Own the design and manufacturing processes for custom harnesses
  • Support design of embedded avionics systems including power, compute, sensing, actuation, and communication subsystems
  • Act as the primary point of contact for any manufacturing issues on electrical assemblies
  • Determine layer stackup, perform component package selection, component placement, routing feasibility studies, and signal routing of digital, analog, RF, and power conversion of printed circuit boards (PCB)
  • Create and release documentation for fabrication of PCBs
  • Own schematic design, component selection, PCB layout, and design review
  • Manage board-level bring-up, debugging, and validation in lab and field test environments
  • Guide board-level manufacturing, testing, and assembly processes (both in-house and external vendors)
  • Establish test procedures for validation, environmental, and EMC/ESD qualification

Basic Qualifications
  • Bachelor's degree in electrical engineering.
  • Strong experience with Altium Designer or similar CAD system (KICAD, EAGLE, CADENCE)
  • Experienced with High-speed digital electronics, embedded microcontrollers, RF components, power electronics, digital buses (CAN, SPI, UART, I2C), sensor integration
  • 1-5 years of experience designing, building, and testing embedded electronics for aerospace, defense, robotics, or automotive systems
  • Proficiency in schematic capture, layout (Altium), and board-level signal and power integrity design
  • Familiarity with environmental design constraints including thermal, EMI/EMC, shock, and vibration

Preferred Qualifications
  • Master's degree or equivalent experience in avionics or high-reliability hardware systems
  • Proven experience delivering complex, multi-board avionics or embedded systems from concept to production
  • Familiarity with NVIDIA Jetson platforms, STM32, RP2040, or other aerospace-class embedded systems
  • Experience in design-for-manufacture and supply chain planning for high-mix, low-volume aerospace production
  • Experience with rapid prototyping, in-house assembly, and validation test campaign.
  • Prior work in systems where the hardware must survive extreme environments (missiles, launch vehicles, hypersonic systems, satellites)

Itar
To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
