About the role

We are seeking a skilled and passionate Senior Product Reliability Engineer to join our dynamic team and contribute to the development and on-site success of utility-grade systems for clean energy.
As Senior Product Reliability Engineer for EQ-S, you will play a pivotal role in bridging R&D and the field for our hardware-driven software products.
You will work closely with the Quality Assurance function to bring real customer-site context, failure patterns, and field-derived test cases back into the product, ensuring that what works in the lab also works on energized sites.

Partner with the Delivery team on Factory Acceptance Testing (FAT) and project bring-up, providing development-side validation of test protocols, configurations, and shipped releases prior to site dispatch.
Support the Deployment team on site-specific configuration, system setup, and integration troubleshooting from commissioning through Commercial Operation Date (COD).
Tune and validate product performance to meet specifications across diverse customer site configurations - including varying project size, networking topology, and hardware composition - and confirm the product behaves to spec under each customer's deployed architecture.
lead structured Root Cause Analysis (RCA) and own issues end-to-end through reproduction, corrective action, and verification on the next release.
Operate a closed-loop corrective-action process that feeds field insights back into design reviews, failure-mode analyses, and the regression test suite.
maintain reliability and availability metrics per site and across the fleet.
Act as the first point of contact from the development team for on-going site issues after handover; lead structured Root Cause Analysis (RCA) and own issues end-to-end through reproduction, corrective action, and verification on the next release.
Author and execute commissioning protocols, performance test plans, and customer-facing acceptance documentation; maintain reliability and availability metrics per site and across the fleet.

Experience producing customer-facing technical artifacts - commissioning reports, RCA / 8D reports, runbooks, SOPs, and dashboards.
Experience with agile development methodologies and modern software engineering practices.
Valid passport required.
5+ years of experience in software-intensive product development, field engineering, commissioning, or product reliability, with demonstrable hands-on customer deployment experience.
Proven track record of leading or supporting commissioning activities for complex hardware software systems, including FAT, SAT, hot commissioning, and performance / capacity testing.
Familiarity with industrial and grid protocols (e.g., Modbus, DNP3, SunSpec, IEC 61850, IEEE 2030.5, MQTT, NATS) and experience validating distributed, event-driven systems.

Bachelor's degree in Electrical, Computer, Software, Systems, or Mechanical Engineering, or related field.
Advanced degree or equivalent experience preferred.
ASQ Certified Reliability Engineer (CRE) and / or NFPA 70E electrical safety / HV switching authorization preferred, or willingness to obtain post-hire.

Working knowledge of utility-scale Battery Energy Storage System (BESS) architecture, power electronics, and battery management systems.
Able to work independently and escalate to surface roadblocks and risk mitigation.
Strong problem-solving skills, attention to detail, and passion for clean technology innovation.

$90,000 - $130,000 + annual bonus (paid in local currency; range varies by location)

At Canadian Solar, our vision is to make lives better by bringing electricity powered by the sun to millions of people worldwide.
We understand the importance of work-life balance and provide various flexible work options to support our employees' well-being.
Partner with the Quality Assurance function to extend test coverage with field-derived scenarios
contribute to hardware-in-the-loop (HIL) testing, regression and soak coverage, and CI integration for software and firmware releases.
Participate in a shared on-call rotation for post-COD critical site incidents; lead blameless postmortems and ensure lessons learned become permanent regression coverage.

Advocate for customers inside R&D - bringing field constraints, deployability concerns, and observed defect patterns into sprint planning, design reviews, and release readiness - and collaborate with development, product, and project teams to drive defect resolution into product releases.
