Trystar
Staff Mechanical Engineer – Power Distribution
Trystar is a leader in power inverters, distribution equipment, and related services, supporting the electrical infrastructure and delivering industry‑leading products and services. We value safety, integrity, customer focus, speed, teamwork, change, and enjoyment of the journey.
Base Pay Range $135,000 – $155,000 per year
Job Description The Staff Mechanical Engineer will lead design efforts in Power Conversion Solutions, creating new designs, advising on existing projects, and acting as a trusted team member with R&D, internal, and external stakeholders. The role is based in one of the following locations: Burnsville, MN; Houston, TX; Charlotte, NC; Merrimack, NH; or Pointe‑Claire, Québec. In‑person office presence is required. Responsibilities include:
Perform complete mechanical design, including layout, part/assembly modeling, drawings, and mechanical requirements definition.
Support advanced engineering analysis: system‑level thermal analysis, Finite Element Analysis (FEA), and Computational Fluid Dynamics (CFD) simulations.
Define, design, prototype, validate, and support mechanical systems for products such as rack‑mounted equipment, modular power devices, UPSs, rectifiers, inverters, and more.
Lead mechanical design reviews and provide technical guidance across multiple product lines at Trystar sites.
Collaborate with hardware design engineers on PCB mounting and packaging requirements.
Develop detailed 3D CAD models and drawings, including complex surfaces, routed assemblies, and mechanical enclosures.
Work with QA, manufacturing, and assembly to improve product designs, documentation, and manufacturability.
Design and validate assembly and test fixtures; support prototype builds and production launches.
Manage BOMs and 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 standardization of design practices across sites.
Provide technical mentorship and guidance to design engineers, test technicians, fabrication, and assembly personnel.
Job Requirements Basic Qualifications
Bachelor’s degree in Mechanical Engineering or equivalent.
Minimum seven (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) in 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, NEMA, UL, IEC, and related mechanical engineering standards.
Proficient in generating and reviewing engineering documentation, including BOMs and detailed drawings for sheet metal, plastic, and extruded parts.
Proficient with Microsoft Office and Microsoft Cloud services.
Travel up to 20% within the USA and Canada.
Additional Qualifications
Experience with UL 1741, CSA C22.2, and other relevant certifications.
Strong oral, written, and presentation communication skills with the ability to influence across all levels of the organization.
Ability to adapt and thrive in a fast‑paced, evolving work environment.
Professional Engineer (PE) license is a plus.
Ability to excel working as the sole mechanical engineer on a project.
Ability to create project requirements from incomplete inputs.
Strong understanding of structural and thermal analysis (FEA/CFD tools such as SolidWorks Flow Simulation, ANSYS, COMSOL, or similar).
Seniority Level Mid‑Senior level
Employment Type Full‑time
