Transaera is developing a new class of affordable, energy-efficient, sustainable cooling systems designed to address the 40% of global energy greenhouse gases emitted by conventional HVAC. Transaera's novel desiccant technology uses a unique sponge-like material that grabs moisture from the atmosphere to enable its air conditioner to cool air more efficiently. The heat generated by the air conditioner is then used – instead of being wasted – to dry the material for the next cycle.

Transaera is looking to hire an Engineering intern to support the team in prototype development of our AC design. This includes iterative design and build of prototypes and test fixtures, as well as data acquisition and analysis for design validation. We are looking for someone who is organized, creative, and collaborative.

Key Responsibilities include:

  • Designing, prototyping, and constructing electromechanical systems to support coating process development.

  • Developing and assembling custom equipment, including mechanical fixtures and automated systems.

  • Performing equipment validation, collecting and analyzing data, and reporting findings to inform design improvements.

  • Creating and documenting procedures for equipment operation and maintenance.

  • Managing and organizing the prototyping workspace, tool inventory, and test infrastructure.

  • Iterating on existing designs using CAD modeling and rapid prototyping methods such as 3D printing or laser cutting.

About you:

  • Excited about the future of climate tech

  • Want to work with a growing, fast paced team that is revolutionizing AC

  • Take initiative to get things done, and are not afraid to ask questions
