You’ll assist with product teardowns, root-cause analyses, and design reviews, while analyzing sensor and warranty data to identify trends. You’ll also help prepare reports using statistical tools to define performance targets and assess risk. You will have the opportunity to take the lead on projects and gain hands-on experience in product development, data analysis, and engineering problem-solving.
• Quality Assurance Engineering: Assists in improving quality systems. Works to enhance In-Line product quality and testing of refrigeration/cooking systems and structural dimensions with an emphasis on data capture and analysis.
•  Manufacturing Engineering – Fabrication:  Support and enhance manufacturing operations with a focus on Fabrication and New Product Development. You’ll apply principles from Industrial and Mechanical Engineering to analyze processes, design fixtures, and drive improvements in productivity, efficiency, safety, and quality across the plant. In the Fabrication area, you’ll collaborate closely with CNC programmers and design engineers to ensure manufacturability and safe production of components. You’ll also contribute to New Product Development by supporting prototype builds, refining fabrication methods, and integrating feedback into design iterations. Gain hands-on experience with SolidWorks for CAD modeling and drawing creation and develop a strong understanding of how engineering decisions impact real-world manufacturing outcomes.
• Manufacturing Engineering - Assembly: Support and enhance manufacturing operations with a focus on Assembly and New Product Development. You’ll apply principles from Industrial and Mechanical Engineering to analyze, develop, and drive improvements in assembly processes. In the Assembly area, you’ll work closely with manufacturing engineers, production teams, quality engineers, and design engineers to support the implementation of new products. You’ll assist with fixture and tooling development, time studies, process documentation, safety evaluations, and continuous improvement initiatives.  Gain hands-on experience with CAD tools, manufacturing systems, lean manufacturing principles, and real-world problem-solving while developing a strong understanding of how engineering decisions impact assembly operations, product quality, and overall manufacturing performance.

• Azure IoT Engineering: Work alongside mobile and embedded software teams to develop the Cloud IoT solutions that make our products smart. Activities include backend software development, software design, automated testing development, defect investigation, and participating in Agile ceremonies. 

• Mobile Software Development: Collaborate with mobile, cloud, UX, and QA teams to develop and validate features for the Sub-Zero Group Owner’s App. Responsibilities include mobile application development, feature testing, bug investigation, and supporting connected appliance experiences for customers across iOS and Android platforms.  

• Embedded Test & Validation: Work with software development team to develop and execute testing of Sub-Zero appliance firmware. Activities include but are not limited to automated test development, manual testing, and troubleshooting of electronics. This role also includes development of test rigs involving wiring, soldering, and other hands-on assembly and debug.  

• Controls Hardware Engineering: Work alongside the hardware team to validated hardware embedded design solutions that bring our products to life. Activities include designing of PoC’s (Proof of Concept) in Altium with aid of lead design engineer, outputs would include schematics, PCB design files, and BOM’s. Candidate would build PCBA samples for engineering verification and validation testing including hand soldering of through hole and surface mount components to PCB. Perform PoC design verification using oscilloscopes, DVM’s, programable power supplies.  Create and execute Test procedures and compile test data in test reports with aid of lead engineer.  Assist with Altium library component work as needed with aid of lead engineers.

• Supplier Quality Engineering: Work closely with Quality Engineers, Supply Chain, Manufacturing, and Design Engineering teams to identify the root causes of supplied-part issues that impact assembly lines. Use data and statistical tools to support reporting, drive continuous improvement, and strengthen supplier quality performance.
