Senior Embeded QA Engineer

About the Role Senior Embeded QA Engineer responsible for testing controller applications, supporting field issues, and contributing to documentation that ensures products are deployed correctly in real-world environments and that what is designed in development works under real conditions with real constraints. You will validate end-to-end systems at the intersection of software, controls, and field application.

What You'll Do

• QA Testing & Validation: Perform functional and system-level QA testing of Refrigeration Case Controllers, CO2 High Pressure Valve controllers, and 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 based on field learnings; support beta deployments, validation, feedback collection, and issue tracking.
• Documentation & Controls Understanding: Read, interpret, and validate control schematic, wiring diagrams, Sequences of Operation (SOPs), and 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.
• Cross-Functional Collaboration: 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.

What We're Looking For

• Associate or bachelor’s degree in engineering (Electrical, Mechanical, Controls, or related field) or equivalent experience
• 5+ years of experience in QA, or field support (HVAC/Refrigeration preferred), developing or testing control systems, embedded applications and algorithms
• 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
• Fluent written and conversational English language skills (CET-4 or better)

Nice to Have

• 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
• Experience with testing web-based firmware applications and Linux-based systems
• Experience with ApTest Manager, JIRA, Rally
• Experience with MODBUS/BACNet protocol and network testing
• Performance/load test experience
• Experience with API test tools like Postman
• Good understanding of QA methodologies and QA Automation tools
• Experience with Jenkins/Hudson, Maven/Ant for release management
• Experience with Selenium and Java/Python/C# coding
• Knowledge of product lifecycle and Agile methodology

Compensation & Benefits

• Flexible and competitive benefits plans offer the right options to meet your individual/family needs. We provide employees with flexible time off plans, including paid parental leave (maternal and paternal), vacation and holiday leave.
