Thermal Systems Engineer

Company Mission

Quilt's company mission is to move humanity off of fossil fuel heating. 20% of US global warming emissions come from homes (that's more than cars!). The largest driver of home emissions is burning fossil fuels for heat. To stop climate change, over 80M US homes need to transition from combustion to efficient, electric heat pumps over the coming decades.

We believe for this to happen the world needs fantastic products that are easy and desirable to purchase. Today's heat pumps lack great design, make limited use of software, and are difficult and stressful to adopt. We are building a next generation, beautifully designed, smart home heating and cooling system that is 10x better than what is on the market today.

Role

Quilt is hiring a Thermal Systems Engineer to optimize deployed systems and support development of our next generation systems. This is an excellent opportunity for an early-career engineer to dive deep into real-world applications of a thermal system, gain testing, analysis and system design skills while contributing to products that combat climate change.

You will work closely with our thermal and cross-functional teams to conduct thermal testing, analyze system performance, develop thermal models, and support the design of next-generation HVAC products. The ideal candidate has strong thermal engineering fundamentals, is eager to learn, and is excited about applying their skills to real-world climate solutions.

Minimum Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field with coursework in thermodynamics, heat transfer, and fluid mechanics
• Understanding of fundamental thermal engineering principles including refrigerant cycles
• Familiarity with refrigerant system components, key process parameter, and common failure modes
• Basic familiarity with data analysis and visualization using Python, MATLAB, or similar tools
• Strong problem-solving skills and ability to work through technical challenges methodically
• Excellent communication skills and ability to document technical work clearly
• Ability to communicate with non-technical stakeholders, such as customer support representatives and HVAC tec
