QA Engineer – Refrigeration & HVAC Controls

Job title: QA Engineer – Refrigeration & HVAC Controls

About the Role We’re looking for a QA Engineer who can do more than execute test cases. This role sits at the intersection of software, controls, and field application, so it requires someone comfortable validating systems end-to-end—not just checking boxes. You’ll be responsible for testing controller applications, supporting field issues, and contributing to documentation that ensures products are deployed correctly in real-world environments.

What You'll Do

• QA Testing & Validation: Perform functional and system-level QA testing of Refrigeration Case Controllers, CO2 High Pressure Valve controllers, HVAC Zone control applications; validate control logic, alarms, fail-safes, and system interactions; develop, execute, and maintain test plans, test cases, and test reports; perform regression and integration testing across firmware and application updates; identify defects, document root cause observations, and work with engineering for resolution.
• Field & Product Support: Participate in field support calls to troubleshoot real-world issues; analyze logs, system behavior, and configurations to diagnose problems; provide feedback to development teams; support beta deployments, including validation, feedback collection, and issue tracking.
• Documentation & Controls Understanding: Read, interpret, and validate control schematics, wiring diagrams, SOPs, MOPs; contribute to or review technical documentation to ensure alignment with product behavior; bridge gaps between documentation, implementation, and field expectations.
• Cross-Functional Collaboration: Work closely with development, product management, and field teams; participate in test planning, design reviews, and release readiness discussions; provide input on usability, reliability, and deployment risks.

What We're Looking For

• Required Qualifications: Associate or Bachelor’s degree in engineering (Electrical, Mechanical, Controls, or related field) or equivalent experience; 2–5 years of QA, testing, or field support (HVAC/Refrigeration preferred); strong understanding of testing methodologies and defect tracking; ability to read and interpret electrical schematics and wiring diagrams; hands-on experience with embedded systems or controller-based products; strong analytical and problem-solving skills; ability to work independently and handle ambiguity in real-world scenarios.
• Nice-to-Have: Basic knowledge of Controls Engineering (PID loops, sensors, actuators, control logic); familiarity with CO2 refrigeration systems or HVAC applications; experience with Modbus/BACnet, logging/diagnostic tools, test automation frameworks; experience supporting field deployments or working directly with customers.

Compensation & Benefits

• Our Commitment to Our People: We offer flexible and competitive benefits including medical insurance, dental and vision coverage, 401(k) and more; flexible time off plans including paid parental leave, vacation, and holiday leave. We emphasize onboarding and leadership development to help you thrive personally and professionally.
