Vacancy: Sales Engineer – Sustainable Technology
Are you a driven Sales Engineer with a passion for sustainable technology? Do you combine technical insight with commercial skills—and want to make a real difference in the industrial energy transition? Then we’re looking for you.
The challenge
At Heat Matrix and Bos Nieuwerkerk, we turn industrial heat loss into measurable sustainability gains. As a Sales Engineer, you translate complex heat recovery projects into concrete business cases that drive carbon reduction in the industrial sector. You’ll work at the intersection of engineering and commerce—combining technical depth with strategic stakeholder engagement.
Your impact
- Help industrial clients achieve their sustainability goals
- Directly contribute to 15–20% CO₂ reduction per project
- Manage 3–5 complex industrial projects simultaneously
- Realise €2–4M in new projects annually
- Develop new product-market combinations
About Heat Matrix and Bos Nieuwerkerk
Heat Matrix has been a trusted partner in advanced heat recovery systems for over 15 years—with a track record of patented innovations and proven business cases. Bos Nieuwerkerk brings deep expertise in engineering and execution, delivering complex turnkey flue gas systems. Together, we help clients in sectors such as food & beverage, bakery, manufacturing and chemicals to significantly improve and decarbonise their process installations.
“I develop heat recovery concepts and guide implementation. There’s no hierarchy here—everyone helps each other. That’s what I really value.”
Rik Kuenen, Project Engineer since 2020
Recent project highlight
For a client in the chemical industry, we reduced flue gas temperatures from 250 °C to 30 °C for scrubbing. Previously, 1.5 to 3.0 MW of thermal energy was wasted. Our challenge: the gases contained high levels of sulphur, making them highly corrosive.
We designed and implemented a total solution—supplying a high-performance polymer heat exchanger, all ducting, a powerful fan and full structural support. Today, the flue gas is cooled from 250 °C to 120 °C before entering the scrubber. The recovered thermal energy (1–2 MW) is reused elsewhere in the process, saving over 8,300 tonnes of CO₂ over five years.
