Position Title: BESS Associate Validation Engineer

Department: Engineering

Entity: CS e-Storage

Reports To: Sr. Deployment Engineering Manager (AMER)

Location: Remote, Canada & US

Position Summary:

The Associate Validation Engineer plays a pivotal role in leading hands-on integration, functional testing, and coordination for utility-scale Battery Energy Storage Systems (BESS). Combining field coordination with technical execution, this role is responsible for authoring test procedures, executing subsystem-to-system validation, and diagnosing complex hardware, software, and industrial networking issues across PCS, BMS, and EMS platforms.

Key Responsibilities:

• Coordinate schedules and manage logistics for BESS subsystem/system testing (PCS, EMS, BMS, BCI, safety systems)—including test equipment inventory, tool shipments, site access, and field personnel.
• Maintain validation test plans, issue logs, execution trackers, and punch lists, delivering regular progress reports to internal and external project stakeholders.
• Track open validation issues and collaborate cross-functionally with internal development teams, technical leads, and vendors to facilitate timely resolution.
• Support field teams with current validation documentation and revision control, ensuring pre-test conditions are satisfied and executed in compliance with project standards and timelines.
• Contribute to the optimization of validation workflows, testing methodologies, tools, and standardized templates.
• End-to-end ownership of integration and validation documentation—authoring detailed test procedures, defining acceptance criteria, executing tests directly or directing third parties, analyzing raw test logs against pass/fail criteria, and completing test reports.
• Design test architecture setups, including physical wiring, hardware interfaces, auxiliary equipment, and software tools.
• Own and execute all validation tasks related to Canadian Solar vertically integrated product line, included but not limited to BESS, Inverters and Plant Controllers with support from cross-functional engineering teams.
• Perform hands-on testing, signal analysis, and hardware/software/communications troubleshooting across BESS, BCIs, PCS, and BPC control hardware during integration testing.
• Interface and collaborate with third-party certifying labs and agencies (NRTLs such as UL, CSA, Intertek) to coordinate and execute validation testing required for system-level safety and compliance certifications.

Related Experience:

• 2+ years in energy, renewables, industrial controls, or utility-scale infrastructure projects.
• Experience supporting validation, integration, or commissioning efforts involving power systems, automation, or SCADA.
• Exposure to or familiarity with BESS-related subsystems such as PCS, EMS, BMS, or protective relaying.
• Familiarity with or exposure to product certification standards (including but not limited to UL 9540, UL 1741, UL 1973, and UL 1998) and working with accredited testing laboratories.
• Hands-on experience with technical documentation, test execution tracking, and issue management tools (e.g., Excel, Jira, SharePoint, Trello, Smartsheet).
• Understanding of electrical single-line diagrams, network block diagrams, and validation workflows.
• Experience collaborating across engineering, operations, and field service teams.

Personal Qualifications:

• Highly organized and detail-oriented; capable of juggling multiple validation tasks across different projects.
• Strong written and verbal communication skills, with the ability to clearly summarize technical issues and coordinate between teams.
• Proactive and resourceful in following up on open issues and ensuring validation tasks stay on track.
• Comfortable coordinating logistical elements such as site access, shipping, and personnel scheduling.
• Able to work independently but also thrives in a collaborative, cross-functional team environment.
• Comfortable working in a fast-paced and evolving technical landscape.
• Willingness to travel to validation sites (up to 50%) to support field validation activities.

Future Technical Competency & Growth Objectives:

• Author, execute, and troubleshoot specialized grid-compliance test procedures, including Grid-Forming (GFM), Black Start, and fast frequency/grid-code response capabilities.
• Perform control loop integration and compatibility testing between multi-vendor Battery Energy Storage, Power Conversion Systems (PCS) and Plant Power Controllers (PPC) to ensure system stability prior to field commissioning.
• Lead laboratory, factory, and international on-site validation campaigns, managing physical installation, signal capture, data plotting, and technical coordination with partner engineering teams.
• Perform field industrial networking diagnostics—using tools such as Wireshark and Modbus Poll to capture packet traffic, verify register maps, simulate control commands, and resolve communication line dropouts.
• Remotely and locally navigate, configure, and operate multi-vendor PCS, BMS, and EMS graphical interfaces (HMIs/UIs) for system diagnostics and functional verification.
• Develop working technical knowledge and execution capability around key product certification standards, including but not limited to UL 9540 (BESS system safety), UL 1741 (PCS/inverter grid interconnection), UL 1973 (battery energy storage), and UL 1998 (software safety).
