HVAC Design Engineer & Co-Founder

Location: Remote / Hybrid (Preferred: Uttar Pradesh, India)

Type: Co-Founder | Equity + Future Salary

Company Stage: Early-stage, bootstrapped, pre-funded (funding in progress)

About Us

We are building a pioneering District Cooling-as-a-Service (DCS) company focused on delivering clean, affordable, and efficient cooling for commercial buildings, malls, and urban clusters. Our first 500 TR pilot plant is being developed in Uttar Pradesh, with chilled water supplied via underground pipelines, replacing outdated, energy-hungry ACs.

In parallel, we are also working on a new air-conditioning product, a disruptive, next-gen cooling solution that merges energy efficiency with advanced thermal engineering for commercial users.

What We’re Looking For

We’re seeking a Co-Founder with deep expertise in HVAC product design to help us build a next-generation air conditioning system for commercial users. While we are developing a District Cooling System (DCS) in parallel, this role will primarily focus on designing an innovative cooling product from scratch, optimized for energy efficiency, performance, and manufacturability.

You’ll lead the end-to-end HVAC design of this new product, including refrigerant system design, indoor/outdoor unit configuration, airflow, heat exchangers, casing, sensors, and controls. This is a chance to build an entirely new class of AC technology that’s smarter, more efficient, and better suited for the Indian market.

Key Responsibilities

• Lead the design and prototyping of a new air conditioning product tailored for commercial users (restaurants, retail, hospitals, offices)
• Design key components such as cooling coils, expansion valves, casing, Condenser coil, fans, Evaporators coils, etc.
• Select optimal refrigerants and model refrigeration and heat transfer performance
• Conduct simulations for airflow, pressure drops, and temperature control
• Create 3D models and work closely with fabrication partners for prototype development
• Ensure modularity, serviceability, and cost-effective manufacturing of the system
• Align product design with real-world building constraints and energy regulations
• Prepare technical documents, test protocols, BOMs, and performance reports

Ideal Background

• Bachelor’s or Master’s degree in Mechanical, Refrigeration, Thermal, or HVAC Engineering
• 3-5+ years of core experience in HVAC product design, especially in commercial or industrial AC systems
• Strong grasp of heat exchanger design, refrigerant cycle optimization, fan and motor selection, thermal and CFD simulation
• Experience with tools like SolidWorks, AutoCAD, Ansys, or other HVAC modeling platforms
• Experience working with component manufacturers, vendors, or in R&D teams of HVAC companies
• Practical knowledge of thermodynamics, psychrometrics, HVAC testing protocols, and system prototyping
• Bonus: Exposure to green HVAC technologies, energy-efficient designs, or patent/IP development

What’s in it for You

• Become a core team member and co-founder from the ground up
• Substantial equity ownership (to be discussed based on fit and commitment)
• Salary and compensation post-funding (currently bootstrapped)
• A chance to co-build the future of clean cooling in India
• Work alongside a visionary founder, early customers, and industry partners
• Full creative and technical ownership of system design
