What this role is

An experienced electrical technician who independently installs, tests, and maintains power and signaling systems. At the Senior Support Specialist (S3) level, the role owns escalated / complex cases, complex or non-standard cases, and drives resolution quality on the team's hardest cases. Guides junior support informally.

What this level does

  • Independently take a package of schematics, load calculations and test documentation from redline to release, exercising judgment on moderately difficult drafting and check-print decisions without daily instruction
  • Set up non-routine prototype test rigs — including MATLAB/Simulink model runs or PSIM simulations the engineer requests — and interpret results to help isolate a failing component or wiring fault
  • Own compliance checks against NEC and OSHA on assigned drawing sets, reconciling discrepancies with the engineer and correcting the documentation
  • Coordinate the drafting and test-log tasks of one or two junior drafters/technicians on a project, sequencing their work against project deadlines
Knowledge applied
Detailed knowledge of drafting, calculation and test procedures sufficient to handle non-routine drawing packages and simulation setups.
Complexity & problem solving
Makes judgments on moderately difficult check-print, compliance and test-isolation tasks; carries out routine work independently.
Collaboration & interaction
Little instruction on daily work; coordinates the drafting/test tasks of one or two junior staff without formal leadership.
Typical experience
2–4 years; skilled in the electrical support function.

Skills at this level

AutoCAD Electrical drafting
Produces electrical schematics, panel layouts and wiring diagrams in AutoCAD Electrical from sketches and redlines, applying wire-numbering, cross-referencing and title-block conventions.
Electrical calculations
Performs voltage, current and load calculations into standard worksheets to support conductor sizing and component selection on drawing packages.
Codes, standards, and compliance
Checks drawings and assemblies against NEC and OSHA reference tables for conductor sizes, clearances and labeling, and reconciles discrepancies for engineer review.
Prototype build and bench testing
Sets up and runs prototype rigs and continuity, insulation and load tests on electrical components or assemblies, recording results against expected ranges.
Design & simulation software
Runs MATLAB/Simulink models and Powersim PSIM simulations at engineer request to reproduce circuit behavior and help isolate faults.
Design documentation and revision control
Logs design revisions in the drawing register, compiles engineering reports, and keeps revision states aligned across multidisciplinary drawing exchanges.
Multidisciplinary coordination
Coordinates day-to-day drawing and data exchange with mechanical and other engineering disciplines to keep an electrical package consistent.
Quality control analysis
Conducts check-print reviews and inspections of test data to evaluate that drawings and prototypes meet specification before release.
Procedure development
Creates and documents new drafting conventions, test procedures and calculation templates for the electrical support group to follow.
Coaching/mentoring
Guides less experienced drafters and technicians on tools, standards and check-print practice as an informal working lead.
