Hardware Engineer

**About the project** We're building a small, safety-critical kinetic munition delivered by an FPV-class airframe. The compute side is an electro mechanical safe and arm device (EMSAD). You'll own the electronics — from schematic, through PCB layout, through bring-up and qualification of every board in the system. **What you'll do** Architect and design the main EMSAD board and auxiliary boards. Handle schematic design and multilayer PCB layout. Define hardware safety architecture with redundant interlocks and fail-safe defaults. Build and run bring-up benches and first-article validation. Collaborate closely with firmware engineers on drivers and timing. Drive environmental qualification: thermal, vibration, EMC, ESD, drop testing. Own BOM management, DFM/DFT, and factory tester development. **Required** 5+ years of professional electronics design experience. Strong knowledge of low-power MCUs, mixed-signal systems, power supplies, sensors, and RF-adjacent layout. PCB layout expertise in tools such as Altium, KiCad, or Cadence. Hands-on lab debugging skills using oscilloscopes, logic analyzers, DMMs, and soldering tools. Experience debugging complex hardware issues including EMC and brown-out edge cases. Strong written and verbal English communication. **Nice to have** Safety-critical or fail-safe hardware design experience. Experience with S&A or fuzing electronics. Familiarity with MIL-STD-810 / MIL-STD-461 testing. FPV / small-UAV electronics experience. DFT for high-mix low-volume manufacturing
