🚀 Join Spark Cleantech : At the Heart of Sustainable Innovation

🌱 Sector: Deep Tech / Cleantech / Innovation

✨ Who We Are

Spark Cleantech is a fast-growing and innovative start-up developing a breakthrough process that replaces the combustion of hydrocarbons in high-temperature industrial furnaces and in materials production with an alternative that is not only fully decarbonised, but also economically competitive and requires only minimal adaptation to existing industrial processes.

Following the successful deployment of an industrial pilot on a client site in 2024 and a major funding round in 2025, we are now building our first industrial standard.

Our ambition is bold: to address, by 2027, sectors that represent 10% of the global CO2 emissions on a multi hundred Bn€ market.

To support this growth, we aim to hire around 20 talented individuals to join our team who share our vision, contributing to a more sustainable world, and our values: positivity, passion, and high standards. We are looking to bring together top experts in their fields to industrialize a technology that comes with exciting challenges.

Our team is passionate, positive, and committed to building a cleaner future. If you’re looking to join a high-impact, ambitious, and innovative project, we’d love to hear from you!
