شرح موقعیت شغلی


Position Summary

PreMax is seeking a Senior Mechanical Engineer with deep expertise in industrial vibration systems and rotating machinery analysis.

This role is responsible for ensuring that mechanical and vibration signals entering the PreMax system are physically valid, correctly installed, and mathematically defensible. The position plays a foundational role in establishing measurement integrity across industrial environments.


Key Responsibilities


1. Vibration Sensing Architecture

·      Define vibration sensor selection standards (IEPE, charge, MEMS where applicable)

·      Specify required bandwidth, frequency range, and sampling constraints

·      Define mechanical mounting standards (stud, adhesive, torque requirements, surface preparation)

·      Establish cable routing, shielding, and grounding best practices

·      Create clear installation documentation for industrial deployment

2. Mechanical Signal Integrity & Field Validation

·      Validate vibration signal quality in real plant environments

·      Conduct field testing such as impact hammer tests, run-up, and coast-down analysis

·      Identify resonance effects, cross-axis contamination, and structural distortions

·      Define acceptance criteria for sensor installation and signal quality

3. Deterministic Physical Feature Definition

·      Define mathematically reproducible vibration features, including:

o   RMS

o   Peak

o   Crest factor

o   Kurtosis

o   Spectral band energy

·      Document precise transform definitions and windowing rules

·      Ensure feature reproducibility across repeated signal replay

·      Collaborate with engineering teams to ensure features remain non-diagnostic and physically grounded

4. Mechanical Failure Evidence Mapping

·      Map known mechanical failure mechanisms to measurable physical signal signatures

·      Define what measurable evidence exists for rotating machinery degradation

·      Support engineering teams with physically validated signal interpretations (evidence only, not prediction)

5. Cross-Functional Collaboration

·      Work closely with hardware engineers on acquisition integrity

·      Collaborate with firmware engineers on timing and signal alignment

·      Support data engineering teams with validated physical definitions

·      Participate in field deployments and commissioning activities


Required Qualifications

·      BSc or MSc in Mechanical Engineering

·      Minimum 5 years of experience in:

o   Rotating machinery diagnostics

o   Industrial vibration analysis

o   Condition monitoring systems

·      Strong knowledge of:

o   FFT and spectral analysis

o   Order tracking

o   Bearing fault frequencies

o   Structural resonance

o   Shaft dynamics

·      Hands-on industrial experience in manufacturing, heavy industry, or process plants


Preferred Qualifications

·      Experience with high-speed data acquisition systems

·      Familiarity with IEPE sensor systems and industrial instrumentation

·      Understanding of sampling theory and anti-aliasing principles

·      Ability to read hardware schematics and discuss analog front-end considerations

·      Experience participating in hardware validation or industrial commissioning
