Perform sub-assembly and final assembly operations according to:
Engineering drawings, Bills of material (BOMs), Work instructions, and specifications. Use hand tools, torque tools, fixtures, and measurement instruments to complete assemblies accurately. Interpret mechanical and electrical prints, schematics, and assembly drawings
Quality & Inspection
Conduct in-process and final inspections to verify dimensional accuracy, alignment, and mechanical operation. Verify electrical continuity, insulation, and proper functionality per work instructions. Identify, document, and report non-conformances or assembly issues. Support corrective actions and continuous improvement initiatives
Testing & Verification
Support functional testing of assembled components and mechanisms. Assist with mechanical cycling, operational checks, and validation of movement and timing. Document assembly completion and testing results as required
Safety & Compliance
Perform work in accordance with company safety policies, lock-out/tag-out procedures, and quality standards. Maintain a clean, organized, and safe work area. Properly handle tools, components, and materials to prevent damage or injury
Collaboration & Communication
Work closely with engineering, quality, and production teams to resolve technical or assembly issues. Provide feedback on assembly procedures, tooling needs, and product design improvements. Support training and mentoring efforts for less-experienced technicians as needed
Required Qualifications
High school diploma or GED required; technical or vocational training preferred
3+ years of experience in mechanical or electro-mechanical assembly in an industrial or manufacturing environment
Experience assembling electrical or mechanical components, power equipment, or transformer experience strongly preferred
Ability to read and interpret technical drawings and specifications
Proficient with hand tools, torque tools, and basic measuring equipment
Strong attention to detail and workmanship quality
Ability to lift up to 50 lbs and perform repetitive tasks in a shop environment
Preferred Qualifications
Experience with load tap changers, breaker mechanisms, or heavy electrical apparatus
Familiarity with power transformer components or substation equipment
Understanding of basic electrical principles (continuity, grounding, insulation)
Experience working in ISO- or quality-controlled manufacturing environments
Ability to troubleshoot mechanical assembly issues independently
Ability to follow standardized processes while identifying improvement opportunities
Pennsylvania Transformer Technology LLC (PTT) is a US-owned, industry leading manufacturer of a wide range of sizes and types of power transformers for the investor-owned electrical utility, municipal power, and industrial markets. Within its two US locations, PTT manufactures transformers rated from 5MVA to 600MVA and 345kV. This includes substation units, generator step-up units, autotransformers, grounding transformers, mobile transformers, unit auxiliaries, unit substations, and three-phase voltage regulators.
We have a rich heritage that dates back almost a century. Our headquarters is located in Canonsburg, PA and is the former site of McGraw-Edison and Cooper Power Systems transformer operations. Our roots designing and manufacturing power transformers extend back to 1929 with transformers being made in our Canonsburg facility since the 1950s. Our sister facility, devoted to small power transformer production, is located in Raeford, NC and has been producing transformers under current ownership since it was built in 1992.
Capital investments in our manufacturing facility have produced a world-class power transformer plant. Our one-million square-foot facility provides tremendous capabilities; including a one-million pound lifting capacity and an impulse generator capable of 2400kV and 360kJ. We employ experienced design engineers who use finite-element-analysis and 3D computer modelling software to optimize designs. We design/build to customer specifications and industry standards such as ANSI, IEEE, NEMA and CSA. Our ISO-based systems assure maximum dielectric and short-circuit strength resulting in the highest quality, reliability and a long, trouble-free service life. PTT’s promise is to build the best power transformers in the industry through superior processes, work ethic and employee pride.
