Position Title: Sr. Technical Solutions Engineer – Power Technology
Department:Technical Solutions
Compensation:$110,000 - $140,000 + annual bonus (range varies depending on location; paid in local currency)
Reports To: Technical Solutions Manager – Power Technology
Location: Remote – Canada or USA
About the Role:
The Senior Technical Solutions Engineer will play a key role in supporting the development, evaluation, and integration of utility-scale energy storage systems and related power solutions, with a focus on Power Conversion System (PCS), Energy Management System (EMS), medium-voltage transformer (MVT), microgrid, and gas turbine applications.
This position requires a systems-level understanding of electrical power systems, power electronics, and controls, with the ability to navigate both hardware and software engineering contexts. The ideal candidate will contribute to integration testing, internal tool development, solution validation, technical documentation, and cross-functional coordination across multiple products, suppliers, and teams.
For internally developed systems, the engineer will work closely with R&D and global engineering teams to provide direct input on design features, electrical interfaces, validation strategies, and integration requirements. For externally procured products, the focus will be on leading technical due diligence, confirming compatibility with the overall system architecture, supporting standards compliance, and transferring product knowledge to internal engineering, Applications, and Execution teams.
Responsibilities:
- Technical Due Diligence and Product Development Support
- Conduct detailed technical due diligence on inverter, EMS, MVT, and related power-system products to ensure performance, safety, compliance, compatibility, and long-term reliability.
- Develop and maintain internal tools to support system sizing, product design, project development, and the evaluation of new opportunities, while enabling continuous improvement across existing product lines.
- For internally developed products, collaborate with R&D and technical teams to support design development, interface definition, validation testing, and platform roadmap alignment.
- For externally sourced products, lead the evaluation of technical specifications, drawings, certifications, test reports, performance claims, and integration requirements; confirm alignment with the overall solution architecture and support cross-functional knowledge transfer.
- Support Independent Engineer reviews and customer-led technical due diligence by preparing documentation packages, addressing technical and compliance questions, and representing the internal design basis.
- Monitor and interpret evolving product standards, grid codes, electrical requirements, and communication protocols relevant to inverter, EMS, MVT, microgrid, and integrated energy-storage solutions, including applicable UL, IEEE, IEC, and regional requirements.
- Solution Development & Supply Chain Support
- Oversee the development and enhancement of internal engineering tools to support system modeling, product validation, and solution optimization efforts.
- Lead the technical review of new inverter, EMS, MVT, gas turbine, and related electrical products being evaluated for integration into our solutions, including technical specifications, drawings, equipment selection and sizing, certifications, calculations, performance data, and test results.
- Support the definition and review of electrical interfaces between the inverter, battery system, MVT, MV switchgear or protection equipment, auxiliary systems, EMS, and grid connection.
- Coordinate cross-functional communication to introduce new products to internal stakeholders, including engineering, project execution, and applications teams.
- Maintain traceability of vendor/product documentation, internal evaluations, and platform status through internal tools and documentation systems.
- Work closely with procurement, product management, and R&D teams to support alignment between product design, supplier capabilities, and commercial rollout.
- Coordinate parallel supplier and product workstreams, ensuring that technical dependencies, responsibilities, deliverables, and unresolved items are clearly documented.
- Cross-functional Support and Customization
- Participate in integration testing between the inverter skid, battery enclosure and BMS, EMS, MVT, auxiliary systems, and associated electrical equipment to support safe and reliable system operation.
- Lead internal discussions with engineering, product, and software teams to troubleshoot control strategies and support platform optimization.
- Provide technical input and coordination for project-specific requirements, custom feature requests, or client-specific configurations.
- Contribute to the development of internal documentation, reference templates, and knowledge-sharing tools that support consistent product execution across regions.
- Collaborate closely with global R&D and applications engineering teams to align on feature roadmaps and deployment readiness.
- Perform other related duties as assigned by management.
Required Qualifications and Skills:
- Bachelor’s degree in electrical engineering, power systems, controls engineering, or a related discipline; preference given to candidates with a postgraduate degree in engineering.
- Minimum 5 years of experience in engineering, R&D, or project commissioning within power electronics, energy storage, microgrids, power generation, or related industries.
- Direct experience in inverter product development, control systems, or energy storage project commissioning is strongly preferred.
- Strong general electrical-system knowledge, including power systems, power electronics, inverters, plant-level controls, transformers, medium-voltage equipment, protection, and system integration.
- Experience with Battery Energy Storage System (BESS) and microgrid applications, including electrical architecture, equipment interfaces, controls, and system integration.
- Experience with medium-voltage transformers and associated MV equipment, including equipment ratings, selection, sizing, protection, electrical interfaces, and system integration.
- Knowledge of gas turbine systems, including technical evaluation, equipment selection and sizing, operating characteristics, performance assessment, and integration within microgrid or power-system applications, is preferred.
- Familiarity with key standards and certifications related to inverter, EMS, MVT, microgrid, and integrated power-system applications, including applicable UL, IEEE, IEC, medium-voltage equipment, and grid-interconnection requirements.
- Experience collaborating with international partners, particularly engineering or manufacturing teams across global time zones.
- Demonstrated ability to lead or contribute to the development of internal engineering tools, system models, or automation processes.
- Strong technical, analytical, and troubleshooting skills, with a hands-on approach to product validation and integration.
- Proficiency in Mandarin is a plus but not required.
