Job Title: Application Engineer – Load Banks Systems


Job Description:


Trystar is at the forefront of advancing power solutions, charged and driven by a committed, dynamic team, tackling complex challenges, and creating innovative solutions. We’re looking for motivated, driven, and talented individuals eager to be part of the future of power. Safety and integrity aren’t just buzzwords, they are the north star guiding us as we aspire to wow our customers every day. We’ve created power solutions that are not only durable and unique but are also the result of exciting teamwork from every corner of our organization.

Individually and collectively, every team member at Trystar plays for each other and strives to deliver unmatched value and 100% accuracy to our customers every single day. Our cutting-edge headquarters is in Faribault, MN, a facility that is partially solar and wind powered by our own microgrid! Together, we are Trystar, where we power the future and nurture innovation for a brighter tomorrow.

At Trystar, our people are our greatest competitive advantage. We are seeking a highly motivated Application Engineer for Load Banks to join our Applications Engineering team, based out of our Burnsville, MN headquarters with flexibility for remote work.

Reporting to the Senior Manager, Application Engineering, the Application Engineer (Load Banks Systems) will Serve as the principal technical SME for Trystar's resistive, reactive, and resistive-reactive load bank portfolio (5 kW to 10+ MW; 208V–34.5 kV). Own the engineered solution architecture across portable, stationary, trailer-mounted, rooftop, and containerized.

The engineer supports pre-sales application engineering (RFQs, specs, sizing, BOMs, conceptual drawings), enables scope clarity and risk mitigation, and drives clean handoffs to Engineering/Manufacturing while improving responsiveness, quality, and cycle time. Key technical domains include PowerDyne resistor technology, transformer sizing and specification (MV load bank systems), SCCR coordination, UL 508A compliance, and system-level integration with generators, switchgear, and utility interconnects.


We are looking for people who believe in our guiding principles and values of:

  • 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.


In this role you will get to:


1. Product Expertise & Technical Authority (Load Bank Systems)

  • Serve as the system and product SME for Trystar's full load bank portfolio: LV resistive/reactive, MV transformer-coupled load banks, portable, stationary, trailer-mounted, and rooftop configurations.
  • Provide configuration guidance, value engineering, and product selection aligned to application requirements — including PowerDyne resistor technology, SCCR coordination, transformer sizing, and UL 508A compliance.
  • Recommend the right solution path by translating customer specifications into optimal load bank configurations, identifying standard vs. non-standard vs. ETO scope.
  • Maintain deep technical knowledge of generator testing protocols, commissioning loads, data center acceptance testing, and utility load-rejection testing applications.

2. Customer Application Support (Pre- & Post-Sales)

  • Provide application and technical support to customers and internal partners (Sales/FSE/CX) for load bank applications across data centers, utilities, rental fleets, military/government, healthcare, and industrial sectors.
  • Work with customers and design engineers to ensure that load bank equipment meets system requirements — acting as a trusted advisor on sizing, configuration, and integration.
  • Support post-sales troubleshooting of field issues related to load bank performance, control systems, and site integration as needed.
  • Conduct technical discovery calls with customers to clarify load bank application requirements, site constraints, and performance expectations.

3. Pre-Sale / Proposal & Quoting Support

  • Review load bank RFQs and customer specifications; support one-line diagrams, layout reviews, and scope-of-work definition.
  • Support proposals: load bank equipment sizing, BOMs, conceptual drawings, MV transformer specifications, and budgetary quote packages.
  • Lead/support customer design reviews and value engineering for load bank systems — document assumptions, exclusions, and risk mitigations.
  • Ensure compliance with UL/NEC/IEEE/NFPA standards as required for each load bank request.

4. Customization & Modification Planning

  • Evaluate customer-driven modification requests for load bank systems — assess feasibility, engineering effort, and risk before committing to engineering scope.
  • Collaborate with ETO/RDE teams to define custom load bank configurations including non-standard resistor arrangements, enclosure modifications, control system integrations, and MV transformer pairings.
  • Document modification scope clearly to minimize engineering rework and ensure manufacturing readiness.
  • Identify recurring customization patterns and recommend standard product enhancements to reduce future engineering burden.


6. Technical Documentation & Scalable Knowledge

  • Establish and maintain load bank-specific design guides, application notes, sizing tools, and technical reference documents.
  • Develop and maintain load bank product comparison matrices, competitive positioning documents, and FAQ resources for Sales/Field Sales Engineering teams.
  • Author white papers and application notes on load bank technology, testing methodologies, and best practices.
  • Maintain revision control and ensure documentation is current with product updates and engineering changes.

7. Training & Stakeholder Education

  • Deliver load bank product and application training sessions for internal and external stakeholders.
  • Create scalable training modules covering load bank sizing, configuration, MV system integration, and common application scenarios.
  • Support onboarding of new team members with load bank technical fundamentals.
  • Participate in lunch-and-learn sessions, webinars, and sales conferences focused on load bank capabilities.

8. Professional Presence

  • Participate in customer site visits with Sales to support load bank application discovery, technical presentations, and relationship building.
  • Represent Trystar at trade shows, conferences, and industry events relevant to load bank and power testing markets.
  • Maintain a professional and technical presence that reinforces Trystar's position as the premier custom load bank solution provider.

9. VOC Capture

  • Capture actionable Voice of Customer (problem + context + impact) from load bank engagements and translate into product/content actions with the engineering and R&D.
  • Provide market intelligence on competitive load bank offerings, customer pain points, and emerging application trends (e.g., renewable energy testing, battery energy storage commissioning).
  • Collaborate with Product Management on load bank product roadmap input, new product definition, and feature prioritization.
  • Identify opportunities to standardize frequently requested custom configurations into new standard load bank offerings.
