Consultant - Precision Analog Systems - EMI / Grounding Debug
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: [email protected]
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
