About The Position

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. This role directly impacts product quality, field reliability, and customer satisfaction. The QA Engineer will help ensure that what is designed in development works in the field—under real conditions, with real constraints.

Requirements

Associate or Bachelor’s degree in engineering (Electrical, Mechanical, Controls, or related field) or equivalent experience
2–5 years of experience in 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 Haves

Basic knowledge of Controls Engineering (PID loops, sensors, actuators, control logic)
Familiarity with CO2 refrigeration systems or HVAC applications
Experience with tools such as: Modbus/BACnet communication tools, Logging/diagnostic tools, Test automation frameworks (where applicable)
Experience supporting field deployments or working directly with customers

Responsibilities

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 closely with engineering for resolution
Participate in field support calls to troubleshoot real-world issues
Analyze logs, system behavior, and configurations to diagnose problems
Provide feedback to development teams based on field learnings
Support beta deployments, including validation, feedback collection, and issue tracking
Read, interpret, and validate: Control schematics, Wiring diagrams, Sequences of Operation (SOPs), Methods of Procedure (MOPs)
Contribute to or review technical documentation to ensure alignment with product behavior
Help bridge gaps between documentation, implementation, and field expectations
Work closely with development, product management, and field teams
Participate in test planning, design reviews, and release readiness discussions
Provide practical input on usability, reliability, and deployment risks
