Who We Are

Welcome to e-STORAGE, a proud member of the Canadian Solar Inc. (NASDAQ: CSIQ) family! We’re leading the way in designing, building, and integrating advanced battery energy storage systems for utility-scale projects. Our mission? To accelerate the world’s renewable energy transition and create a more sustainable, resilient energy future for everyone.

With our innovative SolBank lithium-iron phosphate battery technology and comprehensive project services, we’re not just building products we’re powering communities and making a difference worldwide.

Position Title: Senior Quality Assurance Engineer

Department: EQS

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

Reports To: Development Manager

Location: Kitchener, ON (Onsite)

About the Role:

We are seeking a skilled and passionate Senior Quality Assurance Engineer to join our dynamic team and contribute to the development of an Energy Management System (EMS) for utility-grade systems. The ideal candidate will be responsible for defining and executing a quality strategy that validates critical user personas and their journeys through the EMS User Interface while ensuring system behavior is correct end-to-end. This includes not only visual UI validation, but also verification of internal service-to service behavior and communications (e.g., MQTT message flows) across the EMS. As Senior Quality Assurance Engineer for EQ-S, you will play a pivotal role in implementing, automating, and supporting the release readiness of leading-edge EMS software platforms used for energy solution digitalization and operating grid energy systems. With peers and architect, you will design and execute an end-to-end test strategy that provides high confidence across EMS workflows, combining Playwright based UI automation with validation of system interactions and telemetry between EMS services. The ideal candidate will possess exceptional skills in test automation engineering for globally distributed energy management systems and be passionate about advancing clean energy initiatives and working collaboratively in a dynamic startup like environment.

Responsibilities:

Lead, develop, execute, and implement end-to-end test strategy for EMS user workflows and system behaviors through the EMS UI.
Develop and maintain automated end-to-end tests using Playwright, ensuring coverage of core EMS workflows and business-critical scenarios.
Test and validate critical user personas and their journeys, ensuring correct role-based access, permissions, and operational flows across monitoring and control functions.
Verify system behavior not only through visual UI validation, but also internal communication through MQTT between various EMS services, validating message topics, payload integrity, sequencing, and system state transitions.
Perform regression testing for each software release to validate system stability and prevent the reintroduction of defects.
Conduct feature testing for new functionalities, verifying that all acceptance criteria and requirements are met.
Design and document test cases based on requirements, user stories, and technical specifications provided by the Company.
Create and deliver comprehensive test reports summarizing test execution results, defects identified, and recommendations for remediation.
Collaborate with development and product teams to clarify requirements, reproduce issues, and support defect resolution.
Maintain and update test automation scripts in alignment with evolving application features and architecture.
Participate in release planning and quality gates to ensure readiness for production deployment.
Support continuous improvement of automation reliability (e.g., reducing flaky tests), test execution speed, and CI/CD integration for rapid feedback and release readiness.
Adhere to Company’s quality standards, security policies, and compliance requirements throughout all testing activities.
Support cultivating a culture of accountability, transparency, and continuous learning, including clear ownership of test stability and fixing failures introduced by changes (e.g., changes impacting MQTT behaviors).
Mentor and guide other Quality Assurance and engineering team members on quality practices, testability, automation strategy, and defect prevention.
Take ownership of their work and contribute to the overall success of the organization.

Required Qualifications and Skills:

Bachelor’s degree in computer science, or related field. Advanced degree or equivalent experience preferred.
Proficient in modern test automation development using TypeScript/JavaScript, and strong understanding of web application testing methodologies.
5+ years of experience in software quality assurance, test automation, and system-level validation for complex software products.
Proven work experience developing and maintaining automated end-to-end tests using Playwright, with focus on maintainability, robustness, and high coverage of business-critical workflows.
Experience validating distributed and event-driven systems, including verification of internal communications and message flows (e.g., MQTT).
Strong experience translating requirements, user stories, and acceptance criteria into test plans, test cases, and automation coverage.
Experience performing regression testing for each release and participating in quality gates to ensure readiness for production deployments.
Hands-on experience with defect management, triage, and root-cause analysis, and the ability to collaborate effectively with cross-functional engineering teams.
Familiar with version control tools such as Git, and have experience in code collaboration CI/CD development.
Understanding of power electronics, battery management systems, and energy storage technologies is big plus.
Able to work independently on assigned tasks and escalate to surface roadblocks and risk mitigation.
Excellent communication and interpersonal skills, with the ability to effectively collaborate with cross-functional teams and communicate technical concepts to non-technical stakeholders.
Passion for clean technology innovation and building systems from scratch.
Have domain experience with software for utility scale photovoltaic or battery energy storage systems is plus.
Excellent problem-solving skills and attention to detail.
Experience with designing test strategy for end-to-end system coverage (UI + services), including test data management and environment readiness.
Knowledge of testing practices for web applications, including UI validation, API testing concepts, and automation reporting.
Familiarity with RESTful APIs and web services.
Experience with test reporting and dashboards, including automated report generation and delivery to stakeholders.
Familiarity with energy industry regulations, standards, and protocols.
Experience with agile development methodologies and modern software engineering practices.
Willingness to travel as needed to support customer engagements, and team collaboration.
