Job summary

Aleron is seeking a Test Engineering Generalist in Wisconsin to design, develop, and own the test capability behind our power electronics validation lab and factory operations. You will build automated Python test software, develop fixtures, and define test requirements to ensure accurate, repeatable validation.

This hands-on role combines software and hardware work: lay out and test components, review wiring and schematics, and perform system-level testing of modules and drives.

Qualifications

• Bachelor of Science in Electrical Engineering, Computer Engineering, Electrical Engineering Technology, or a related technical field.
• Min 5 years of experience in HW test engineering, DVP&R, product validation, or embedded/test software development.
• Experience reading electrical schematics, wiring diagrams, and component specification sheets.
• Experience working safely around energized electrical systems up to 690 Vac and 1500 Vdc.
• Min 2 years of hands-on Python software development for test automation, instrument control, or data acquisition.

Responsibilities

• Design, develop, and maintain Python-based test automation for data acquisition and instrument control.
• Build scripts to drive test equipment and capture, process, and report test data.
• Apply version control, code reviews, and documentation for reusable test software.
• Design test fixtures and hardware for validating power electronic products, motor drives, and control systems.
• Lay out, build, test, troubleshoot, and document electronic components and systems per engineering instructions.

Job description

Test Engineering Generalist

Location: Milwaukee, WI

Employment Type: Salaried direct employee with comprehensive benefits

Industry: Power Electronics

Compensation: Open

About the Opportunity:

The Test Engineering Generalist will design, develop, and own the test capability behind our power electronics validation lab and factory operations - the test software, test hardware and fixtures, test requirements and procedures, and test coverage that other engineers and technicians rely on. This is an engineering role, not a technician role: the Test Engineering Generalist designs and codes automated test software (primarily in Python), designs and specifies test fixtures and hardware, writes the test requirements and procedures that define what "tested" means for a product, and performs test coverage analysis to identify and close gaps. The role also performs hands-on system-level testing - laying out, building, and bringing up electronic developmental components and systems, and validating modules and drives - to stay grounded in what the lab actually needs.

An ideal candidate is an engineer who is as comfortable writing Python as reading a schematic - someone who wants to build the tools and fixtures that make the rest of the lab's testing and production end-of-line automated testers faster, more repeatable, and better documented, while staying hands-on enough to bring up a system on the floor when it counts.

What You’ll Do:

Test Software Development

• Design, develop, and maintain test automation software, primarily in Python, for data acquisition, instrument control, and automated test sequencing.
• Build and maintain scripts and applications that drive test equipment (power supplies, DAQ systems, oscilloscopes, electronic loads) and that capture, process, and report test data.
• Apply sound software development practices (version control, code review, documentation) so test software is maintainable and reusable across programs.

Test Hardware & Fixture Development

• Design and develop test fixtures, harnessing, and hardware for validating power electronic products, motor drives, and control systems.
• Produce and maintain electrical schematics and fixture layouts; participate in design reviews for new test fixture development and material specification.
• Ensure test fixtures and hardware meet electrical safety requirements to prevent shock.

Test Requirements, Procedures & Coverage

• Develop test requirements and procedures that translate product and engineering requirements into executable, repeatable test methods.
• Perform test coverage analysis to identify gaps between product requirements and existing test capability, and recommend or build the tests needed to close them.
• Contribute to the creation of electrical and mechanical test documentation for industrial motor control and power conversion test systems.

System & Product Testing

• Lay out, build, test, troubleshoot, and modify electronic developmental components and systems according to engineering instructions and standards.
• Document and analyze test data; evaluate the performance and reliability of prototype and production units; recommend changes in circuitry or installation specifications to simplify assembly and maintenance.
• Test and validate enclosed systems and loose-part orders, including point-to-point verification of wiring and system layout against schematics, three-phase power hookup, low-voltage circuit checks, bus voltage bring-up, and hookup to customer or test motors to verify drive performance.
• Test and validate modules and drives using engineering drawings and electrical schematics, and document results.
• Support production and service test stands, and help maintain and update existing test stands.

Job Requirements

What You’ll Bring:

• Bachelor of Science in Electrical Engineering, Computer Engineering, Electrical Engineering Technology, or a related technical field.
• Min 5 years of experience in HW test engineering, DVP&R, product validation, or embedded/test software development, including the following:
  • Ability to design test fixtures and hardware from schematic capture through build and safety checkout.
  • Ability to write test requirements and procedures, and to perform test coverage analysis against product requirements.
  • Ability to read electrical schematics, wiring diagrams, and component specification sheets.
  • Experience working safely around energized electrical systems up to 690 Vac and 1500 Vdc.
• Min 2 years of experience with hands-on Python software development (test automation, instrument control, or data acquisition scripting) - be prepared to discuss or show examples of your work.

What Sets You Apart:

• Experience with Altium Designer or similar schematic capture / PCB design tools.
• Experience with AutoCAD Electrical.
• Experience with SolidWorks 3D (mechanical).
• Familiarity with PLCs, embedded controllers, and data acquisition systems.
• Familiarity with instrument control frameworks (e.g., PyVISA), LabVIEW, or MATLAB.
• Knowledge of UL and CE standards as they relate to industrial control panels.
