Experience Level: Mid-Senior, Experience

Required:

5 Years,

Education:

Bachelor's Degree, Job Function:
Engineering, Industry: Defense & Space

Candidate must be comfortable completing an
initial 1‑month onsite training period in Kearneysville, WV
, after which they will relocate back to work from
San Francisco, Los Angeles, or Washington, DC
.

Our client is developing a
small, safety‑critical kinetic munition deployed via an
FPV‑class airframe
. At the core of the system is an
Electro‑Mechanical Safe and Arm Device (EMSAD) responsible for compute, safety, and arming logic. This role owns the
entire electronics stack
— from schematic architecture through PCB layout, bring‑up, validation, and qualification.

• EMSAD Architecture
  — Architect and design the main EMSAD board and all auxiliary boards.
• Schematic & PCB Design
  — Lead schematic capture and multilayer PCB layout for mixed‑signal, low‑power, and RF‑adjacent systems.
• Safety Architecture
  — Define hardware safety architecture with redundant interlocks and fail‑safe defaults.
• Bring‑Up & Validation
  — Build bring‑up benches, execute first‑article validation, and document results.
• Firmware Collaboration
  — Work closely with firmware engineers on drivers, timing, and hardware‑software integration.
• Environmental Qualification
  — Drive thermal, vibration, EMC, ESD, and drop‑test qualification.
• Manufacturing Readiness
  — Own BOM management, DFM/DFT, and factory tester development.
• Lab Debugging
  — Perform hands‑on debugging using oscilloscopes, logic analyzers, DMMs, and soldering tools.

• 5+ years of professional electronics design experience
• Strong knowledge of
  low‑power MCUs
  , mixed‑signal systems, power supplies, sensors, and RF‑adjacent layout
• Expertise with PCB layout tools such as
  Altium, KiCad, or Cadence
• Hands‑on lab debugging experience with oscilloscopes, logic analyzers, DMMs, and soldering tools
• Experience debugging complex hardware issues including
  EMC
  , brown‑out, and edge‑case failures
• Strong written and verbal English communication

• Safety‑critical hardware
  or fail‑safe design experience
• Experience withS&Aor fuzing electronics
• Familiarity with
  MIL‑STD‑810
  /
  MIL‑STD‑461 testing
• FPV or small‑UAV electronics experience
• DFT experience for
  high‑mix, low‑volume manufacturing

A small, fast‑moving engineering team with
weekly hardware iterations
and constant prototyping. Engineers are expected to:

• Drive electrical decisions
• Document design choices clearly
• Stand behind their work during qualification and field validation
