Staff Mechanical Engineer – Power Conversion

Trystar; Cypress (TX); On-site; USD 110,000 - 150,000; Full time

Job summary

Trystar is seeking a Staff Mechanical Engineer to lead design efforts in Power Conversion Solutions, coordinating across R&D and manufacturing to deliver robust power electronics enclosures and systems.

The role requires experience in large-scale hardware, PCB mounting guidance, thermal/structural analysis, and mentoring junior engineers; travel up to 20% within the USA/Canada; in-person presence at our offices.

Qualifications

• Bachelor's degree in Mechanical Engineering.
• 7+ years of experience as a mechanical design engineer, preferably in power electronics design/packaging.
• Experience with power electronic system design (electrical enclosures, panel layout, seismic considerations, heat management) within electrical equipment, heavy industry, or military sectors.
• Proficiency with major ERP and CAD systems (SolidWorks or equivalent).
• Working knowledge of industry codes and standards: ASME standards, NEMA, UL, IEC, and other applicable standards within mechanical engineering discipline.
• Proficient in generating and reviewing engineering documentation including BOMs and detailed drawings for sheet metal, plastic, and extruded parts.
• Proficient with Microsoft Office applications and Microsoft Cloud services.
• Travel up to 20% within the USA and Canada.

Responsibilities

• Perform complete mechanical design, including layout, part/assembly modeling, drawings, and mechanical requirements definition.
• Support advanced engineering analysis, including system-level thermal analysis, Finite Element Analysis (FEA), and Computation Fluid Dynamics (CFD) simulations.
• Define, design, prototype, validate, and support mechanical systems for products such as Rack-Mounted equipment, modular power devices, UPS’s, Rectifiers, Inverters, and more.
• Lead mechanical design reviews and provide technical guidance across multiple product lines at Trystar sites.
• Work with hardware design engineers to develop PCB mounting and packaging requirements.
• Develop detailed 3D CAD models and drawings, including complex surfaces, routed assemblies, and mechanical enclosures.
• Collaborate with cross-functional teams (QA, Manufacturing, Assembly) to improve product designs, documentation, and manufacturability.
• Design and validate assembly and test fixtures; support prototype builds and production launches.
• Manage BOMs, documentation for new and existing parts, using database tools (e.g., Empower, PDM, Epicor)
• Answer vendor questions regarding mechanical parts (change requests, obsolescence, substitution).
• Define and document mechanical requirements and best practices for enclosures of power conversion systems.
• Contribute to efforts to standardize design practices across sites.
• Provide technical mentorship and guidance to design engineers, test technicians, fabrication, and assembly personnel.
