Hardware Design Engineer

Location: On-site at HQ — Costa Mesa, CA (initial 6-month duration) Contract: 6 months to start Start: New hires should become productive within ~1 week via on-the-job training Interview Process Phone screen Technical interview Panel interview at the Costa Mesa office Security / Clearance: US citizenship required Why Hiring Hiring ~7 engineers to support hardware development tasks for an electromechanical propulsion product over a 6-month period. End Product: Electromechanical propulsion product hardware Tech / Domain Environment Altium Designer is the primary required tool Cadence, RCAD, or Mentor Graphics experience offers some flexibility Aerospace experience is not required — domain expertise matters more than industry background Covers analog, digital, and power electronics , especially: Sensors Job Duties Conduct architectural investigations Perform root cause analysis Perform worst-case analysis Support hardware–software integration Improve manufacturing scalability Work across the full hardware development lifecycle (not primarily a test engineer role) Support hardware development for an electromechanical propulsion product Must Haves Hardware design engineering experience across the hardware development lifecycle Experience with analog, digital, and power electronics Experience with sensors, motor drivers, and PCB design Explain buck-converter operation , including inductor current paths when the gate pulse is high and low Select a buck-converter inductor using % current-ripple range and a capacitor using % voltage-ripple range Explain high-side buck-converter switch drive concepts: charge pump, bootstrap, isolated bias supply, gate driver — and which option to use and why Explain switching and conduction losses in a buck-converter FET (equations / how to find switching-loss equation) Explain linear-mode FET operation and losses (loss equation + datasheet checks for linear operation) Draw non-inverting amplifier and differential amplifier schematics and provide the Vin ? Vout equation Explain anti-aliasing filters , PCB placement, cutoff-frequency formula, and sampling frequency for a 150 kHz signal Draw the physical I2C circuit (master ? slave) and explain clock and data lines Draw the physical SPI circuit (master ? slave) and explain MOSI, MISO, CS, and Clock Propose and justify a 6-layer PCB stackup distributing power, ground, and signal layers for analog sensors, a power supply, and a microcontroller Nice to Haves Cadence, RCAD, or Mentor Graphics familiarity Product experience in propulsion Experience bands represented across openings: ~2–4 years , 4–8 years , or 8+ years #J-18808-Ljbffr
