New Role, Engagement Type: Contract / Consulting
Precision Analog Systems - EMI / Grounding Debug - Resumes to:
[email protected]
We're tackling a high-precision analog challenge - and we're looking for the right mind to help solve it.
Our engineering team is working through a complex debug effort involving low-level current and voltage measurement in electrically noisy environments.
The system environment is similar to medical-grade instrumentation - where microvolt-level signal integrity matters and EMI, grounding topology, and layout decisions can make or break performance.
We are seeking a consultant with real-world, hands-on experience solving:
• Electromagnetic coupling issues
• Ground loop and reference instability problems
• Shielding and isolation architecture challenges
• Mixed-signal PCB noise mitigation
• Measurement integrity under industrial EMI conditions
• This is not theoretical modeling work.
We need someone who has successfully debugged and solved these problems in the field.
If this sounds like you - or someone you know - please reach out directly:

Precision matters.
Job Description (Immediate hire)
Location: Flexible (Remote + On-Site as Needed)
Duration: Project-Based
Overview
We are seeking a highly experienced analog systems consultant to assist with debugging and resolving electromagnetic interference (EMI) and grounding-related noise issues in a precision measurement platform.
The system measures extremely small currents and low-level voltages in electrically noisy industrial environments. Performance requirements demand medical-grade signal integrity.
Key Responsibilities
• Diagnose and resolve low-level analog signal noise
• Analyze grounding topology and reference stability
• Identify EMI coupling paths
• Review PCB layout for mixed-signal noise susceptibility
• Recommend shielding, isolation, and filtering strategies
• Support hands-on bench-level debug using instrumentation
• Guide engineering team toward permanent architecture improvements
Required Experience
• 5+ years in precision analog or instrumentation design
• Demonstrated success resolving EMI/grounding issues
Experience in:
• Medical instrumentation
• Industrial measurement systems
• Mixed-signal PCB environments
• Strong oscilloscope and spectrum analysis expertise
• Practical shielding and grounding implementation knowledge
Ideal Background
• Biomedical instrumentation
• High-voltage measurement systems
• Scientific instrumentation
• Industrial sensing platforms
• Signal conditioning & low-noise amplifier design
