Job Title : Sr. Analog Electrical Engineer

Rate : Open to Market

Location details : Everett, WA

Duration : 12+ Months- C2H

Job Description

Client is seeking a highly experienced Analog Hardware Design Engineer to join a fast‑paced, high‑impact product engineering effort. The team is entering a pivotal phase: a new hardware design is about to begin PCA bring‑up, and the engineering team must debug, redesign, validate, and complete a fully functional hardware revision.

This role requires a hands-on analog expert—someone who thrives on debugging complex measurement circuitry, optimizing high‑current designs, and driving iterative improvements. You will be the technical lead in taking the design from first-article prototype to a 100% working, production-ready revision.

Candidates with primarily FPGA or high‑speed gigasample digital backgrounds will NOT be a fit. This is a precision analog + power electronics + measurement systems role.

What You’ll Do

1. New PCA Bring-Up & Rapid Debug

Lead the entire first‑article PCA validation process when boards arrive in the next 1–2 weeks.
Identify, characterize, and isolate root-cause issues across analog measurement, high-current paths, H‑Bridge drivers, and power subsystems.
Document all design faults, performance variances, and unexpected behaviors.
Work closely with cross-functional engineering teams to plan rapid design-turn cycles.

2. Precision Analog & Measurement Circuit Design

Own design, debugging, and improvement of precision analog circuits operating DC to 1 MHz, including:
- Low-noise op amp stages
- Instrumentation amplifier architectures
- High-resolution ADC front-end design
- Measurement accuracy, stability, and drift considerations
Improve circuit performance through simulation (SPICE, LTSpice, QSPICE) and empirical validation.

3. High-Current & Power Electronics Development

Design and characterize high-current (>20A) current sources, ensuring thermal stability, accuracy, and dynamic response.
Apply deep understanding of H-Bridge drivers—preferably using H-Bridges in non-motor applications such as signal routing, switching, precision control, or load modulation.
Diagnose switching losses, cross‑conduction, thermal hotspots, and transient behavior.

4. Thermal, PCB, and Mechanical Integration

Work with heavy copper PCAs (>3 oz copper) to optimize current carrying capacity, heat spreading, and mechanical robustness.
Collaborate with mechanical/thermal engineers on heat sinking, chassis conduction, airflow paths, and component placement.
Drive layout review and revision cycles to meet performance, manufacturability, and regulatory constraints.

5. Simulation, Analysis & Documentation

Create SPICE simulations to validate proposed design improvements prior to layout changes.
Provide detailed documentation including:
- Debug summaries
- Root-cause analyses
- Electrical test procedures
- Redesign proposals
- Final design validation reports

6. Deliver a Fully Functional Hardware Revision
✔ Debug of first PCA spin
✔ Redesign and schematic updates
✔ Layout guidance and review
✔ Validation testing
✔ Hand‑off of a production-ready revision

Required Qualifications (Must-Have)

Precision Analog & Measurement

Demonstrated excellence designing precision analog circuits DC to 1 MHz
(op amps, instrumentation amps, ADC front-ends).
Proven experience designing, modeling, and debugging high‑current sources (>20A).
Deep expertise with H-Bridge drivers, particularly for non‑motor applications.
Strong understanding of signal integrity, noise sources, thermal drift, grounding, and shielding in measurement systems.

Practical Debug Skills

Expert hands-on use of lab equipment:
- Oscilloscopes
- Logic analyzers
- Thermal imagers
- Spectrum analyzers
- LCR meters
Ability to take ambiguous or intermittent failures and systematically isolate the root cause.

Tools & Engineering Software

Proficiency with ECAD tools such as Cadence, Allegro, or Altium.
Strong experience with simulation tools: SPICE, LTSpice, QSPICE, or similar.

Preferred Qualifications (Nice-to-Have)

Experience with impedance control, signal integrity, and EMI/EMC compliance.
Comfort integrating hardware with firmware engineering teams
(low-level drivers, embedded interfaces, register-level behavior).
10+ years of industry experience, preferably in test equipment, metrology, or precision measurement hardware.

Ideal Candidate Traits

The client places a strong emphasis on continuous improvement and practical problem-solving. Ideal candidates will:

Show genuine excitement about hands-on engineering challenges.
Demonstrate a Kaizen mindset—always improving, always learning.
Be proactive and question assumptions instead of accepting the status quo.
Embrace iterative change rather than perfection paralysis.
Seek solutions in parallel with discovering problems.
Create an environment where teammates feel empowered to contribute ideas.
Use the “5 Whys” to drive root-cause investigation.
Combine data, creativity, and engineering intuition to propose low-cost, elegant improvements.
Pull in diverse viewpoints from peers, technicians, and cross-functional partners.
Maintain a mindset of never stopping to improve.
