🌱 About NitroCapt
NitroCapt is a climate-tech innovator revolutionizing one of the world’s largest chemical processes: The nitrogen fertilizer production. Using only air, water, and renewable energy, we create the world’s most sustainable and cost-efficient technology for fixation of nitrogen from the air to make fertilizers.
As global demand for food increases, nitrogen—essential for plant growth—plays a crucial role. However, today’s nitrogen fertilizer industry is heavily reliant on fossil fuels, contributing to CO2 emissions equivalent to those of the global aviation industry.
Our award-winning solution offers a rapid pathway to a decarbonized nitrogen fertilizer industry, providing a business model that not only reduces emissions but also increases profitability for our customers compared to fossil-based fertilizers, and contributes to a resilient food production.
We are now looking for a Microwave Application Engineer to join our team in Uppsala, Sweden.

About NitroCapt
NitroCapt is a climate-tech company creating a sustainable cost-efficient green nitrogen fertilizer with zero emission, using air, water and renewable energy as the only input – a true revolution!
We need fertilizers in order to feed a growing population and nitrogen is the most commonly used plant nutrient. However, the nitrogen fertilizer industry today is fossil-dependent, and the CO2-emissions are at the same levels as the global aviation industry, 500 million tons yearly!
Our award-winning solution provides a quick transition into a decarbonized nitrogen fertilizer industry with a business model that makes our customer more profitable than continuing with fossil-based fertilizers.Microwave Application Engineer
