Principal Electrical Engineer ESA (Electrical Signature Analysis) & Signal Processing (Pre-Sales)

Principal Electrical Engineer ESA (Electrical Signature Analysis) & Signal Processing (Pre-Sales)

Role Overview

This is a technical support to sales role (no quota) focused on acting as the engineering authority in customer discussions. You will lead technical conversations, demonstrate ESA-based fault detection capabilities, and defend the physics and mathematics behind electrical signature analysis (ESA) in real time.

Key Responsibilities

• Lead technical discussions with customer engineering teams
• Explain and defend ESA concepts:
• Sideband analysis, slip frequency, bearing fault frequencies
• Harmonics, VFD behavior, low-current signal detection
• Demonstrate SaaS platform (real-time monitoring, FFT, predictive maintenance)
• Contribute to proposals and SOWs (architecture, signal chain, validation)
• Support pilot deployments (CT setup, gateway configuration, data validation)
• Create technical content (white papers, application notes)
• Provide feedback to engineering on signal-processing performance

Core Requirement

Strong expertise in ESA physics and mathematics, including:

• Fault-related sidebands
• Rotor and bearing fault signatures
• Harmonic behavior and waveform analysis

Ability to clearly explain and derive these concepts in live discussions is essential.

What You Bring (Required)

• BSEE required; MSEE in power systems, signal processing, or controls strongly preferred
• Demonstrated mathematical depth in ESA:
• Phasor relationships, three-phase power physics
• Fault-specific sideband generation, harmonic signatures
• Sigma-delta ADC and FFT signal chain
• Ability to derive rotor bar fault sidebands (e.g., on a whiteboard)
• Ability to lead real-time technical discussions in PdM / FireEWS / signal-processing domains with senior engineering stakeholders
• Comfort with embedded hardware concepts:
• ARM Cortex-M, SPI/I C, schematic and BOM interpretation
• Energy metering ASICs (e.g., ADE9078 or similar)
• Industrial electrical experience:
• Automation, manufacturing, energy, rail, semiconductors, or similar
• Systems involving three-phase motors, MCC panels, protective relaying
• Strong English communication and confidence presenting to multi-stakeholder customer teams

Preferred / Nice to Have

• Experience with low-amperage current detection (relay coils, auxiliary contacts)
• Exposure to PCB-level fault diagnostics (UPS, chargers, controllers, drives)
• Predictive maintenance certifications:
• CMRP, CMRT
• Vibration Analyst (Category I III)
• Knowledge of hazardous area standards (ATEX / IECEx)
• Experience with Python for data analysis or automation
• Familiarity with PCB design tools (KiCad, Altium)

Application Requirement

Include a brief note explaining:

• Your electrical engineering background
• How you would explain the physics of bearing fault detection using ESA in a customer discussion

Submissions without this note will not be reviewed.
