Sr Embedded Systems Engineer - Power Management

Based in Seattle, WA, we are a technology design house building smart, connected products, delivering end-to-end engineering services from concept through production across IoT, Med Tech, and automotive industries. Our work is powered by advanced in-house labs and deep expertise in hardware, software, and AI.

We're seeking a senior embedded systems engineer with a strong hardware-first background in power measurement, characterization, and debug on complex SoC-based platforms. This role is highly hands-on, blending EE lab work, embedded firmware, and system-level software analysis to understand and optimize real-world power behavior.

What you'll do

  • Lead system-level power measurement and debug using lab instruments (scopes, power analyzers, electronic loads)
  • Analyze schematics, power rails, sequencing, and PDNs
  • Build and execute structured power test plans across modes, workloads, and states
  • Correlate electrical measurements with firmware, Linux/Android behavior, and thermal response
  • Investigate power anomalies and performance issues across HW, FW, and system software
  • Collaborate closely with electrical, hardware, firmware, and platform teams

What we're looking for

  • 7+ years in embedded systems with significant EE lab and debug experience
  • Strong ability to read schematics and perform rail-level power analysis
  • Solid embedded firmware experience (MCU, SoC, bootloaders, low-level drivers)
  • Working knowledge of Linux and/or Android system software
  • Experience with complex SoCs (e.g., Qualcomm or similar) a strong plus
  • Comfortable driving investigations independently in ambiguous environments

Benefits

  • Competitive base salary and overall compensation package
  • Full benefits:
    Medical, Dental, Vision
  • 401 (K) with generous company match
  • Generous Paid time off (PTO)
  • Vacation, sick, and paid holidays
  • Life Insurance coverage
  • Opportunity to work on cutting-edge technology projects

Employer is willing to sponsor qualified candidates for a non-immigrant work visa.
