At Tarnoc we are building the next generation of heat pump products for homes. We are working on completely new heat pump technologies for residential buildings to accelerate the energy transition. As a Senior Product Development Engineer at Tarnoc you will be working with our development team on the full hardware stack of the heat pump. As a senior engineer you guide the team in designing, planning and setting priorities for the next generation of heat pumps.

Tarnoc is a startup located at YES!Delft, the incubator of TU Delft. We have developed a new type of heat pump system, the Turbine Heat Pump, that is capable of heating a wide range of houses without the need for large renovations. This enables a much faster energy transition to solve the biggest challenge in the energy transition. We are currently a team of 9 dedicated colleagues with a love for cool tech. After many years of testing and prototyping we are now transitioning into the next phase of the company: commercially scaling our products in the real world, as well as introducing new products into our heat pump lineup.

About the role

As a Senior Product Development Engineer at Tarnoc you will be working on both low-level designs but also on high-level company objectives and targets. You will help shape the technical direction of Tarnoc’s next-generation heat pump platform, balancing product development speed with long-term scalability, manufacturability, and reliability.

Responsibilities

You will be working in a tight-knit engineering team. You will be responsible for determining development paths, planning for projects and guiding the heat pump into production. You will be expected to quickly learn the heat pump system and bring your expertise to the development team.

Culture and working style

At Tarnoc we have a flat organisation with everybody’s input being appreciated on projects. In a startup there are very few pre-set paths and as a team we come together to figure out the best move in an always-changing environment. We work in 2-week development sprints with the whole R&D team, with sub-groups focusing on specific sub-components. We appreciate some good nerd banter and love hearing about personal projects that you have going on. We like direct, kind communication and people who are curious about how things work.
