Safety – We believe everyone should leave Trystar facilities in the same or better condition than when they arrived.
Integrity – We’re honest, transparent, and committed to doing what’s right.
Customer focus – We have relentless focus on our customers and their success.
Right with speed – We use good judgement, make thoughtful decisions quickly, and execute them with purpose and intensity.
Play for each other – We’re a team. We show up for each other and we know that through teamwork we achieve greatness.
Champion change – We know adaptation and improvement are requirements to survive and to thrive.
Enjoy the journey – We create an environment where our team feels appreciated and has fun along the way.

Develop PCB layouts for high-voltage and high-current power conversion systems up to approximately 2000 VDC / 600 VAC, including PCB current paths exceeding 100 A, high-current terminals, and PCB-to-busbar interfaces.
Apply appropriate creepage, clearance, insulation coordination, grounding, isolation, thermal, EMI/EMC, signal-integrity, and power-integrity design practices.
Define stackups, controlled impedance, routing constraints, copper requirements, via structures, and other PCB fabrication requirements.
Collaborate with electrical and mechanical engineers on schematic implementation, PCB floorplanning, packaging, thermal interfaces, connector placement, and ECAD/MCAD integration.
Work with PCB fabricators and contract manufacturers to resolve DFM/DFA, testability, serviceability, fabrication, assembly, prototype, and production issues.
Create and maintain footprints, padstacks, mechanical symbols, constraints, PCB standards, and library content; lead PCB design reviews and mentor other designers and engineers.
Support environmental and regulatory requirements including conformal coating, pollution degree, temperature/humidity considerations, and applicable UL, IEC, IEEE, and IPC requirements.
Design PCB-based engineering and manufacturing test hardware including interface boards, automated test boards, programming fixtures, and functional test fixtures.
