Chief Scientific Officer (CSO) Technical Co-Founder (fmd) role at startup CARBOSLAG

Aachen Germany (RWTH Aachen) On-site / Hybrid Co-Founder / Equity Deep Tech / Climate Tech & Circular Economy

CarboSlag transforms local steelmaking by-products into carbon-neutral treatments for post-mining environmental management combining metal recovery with site-specific mineral engineering to deliver faster lower-cost treatment of post-mining soil and water with scalable revenue through IP licensing and LCA-based carbon benefits.

Founded by T. Beril Basaran (Founder Circularity & Innovation Strategist MSc Urban Design 2 years in venture building) CarboSlag is now at TRL 4-5 pre-seed and pre-revenue backed by a 100K equity-free Spark Fund grant and a win at the Climate Tech Hub / Climate-KIC Europe (No. 1). There is already indicative investment interest at a 50K ticket size and the team (1 founder 2 HiWis 3 experts) has been building at the intersection of chemistry biotech and industrial innovation since February 2026. Whats missing is a Chief Scientific Officer to lead technology development: we are looking for a technical generalist to design and run CarboSlags multi-faceted innovation pipeline.

Technology & innovation leadership
- Own technology development as CSO designing and running a multi-faceted innovation pipeline spanning chemistry biotech and industrial process engineering.
- Take CarboSlags metal recovery and mineral engineering process from TRL 4-5 towards pilot projects and technology demonstrations.

Scientific strategy
- Define the R&D roadmap that turns steelmaking by-products into carbon-neutral post-mining treatments and scope the IP and LCA-based carbon-benefit pathways that underpin future revenue.
- Evaluate and prioritize scientific/technical opportunities across the chemistry-biotech-industrial innovation intersection.
Team & partnerships
- Build and lead the technical side of the team (currently 2 HiWis and 3 experts) alongside founder T. Beril Basaran.
- Support engagement with industrial co-innovation partners and help convert indicative investment interest (50K ticket size) into committed funding.

Core experience
- Broad technical/scientific background spanning chemistry materials science biotech or industrial process engineering CarboSlag is looking for a generalist not a narrow specialist.
- Comfort designing and running a multi-faceted innovation pipeline and taking a process from TRL 4-5 towards pilot demonstration.

Especially valuable
- Experience in mineral processing/metallurgy environmental remediation or carbon capture and LCA methodologies.
- Familiarity with IP strategy and licensing as a revenue model.
- Interest in post-mining environmental management and the mining/industrial ecosystem.

- A funded de-risked starting point: 100K equity-free Spark Fund grant already secured plus a Climate Tech Hub / Climate-KIC Europe win (No. 1).
- Indicative investor interest already in hand (50K ticket size) on top of a team of 2 HiWis and 3 experts already in place.
- Ground-floor CSO / technical co-founder equity in a circular-economy venture with a clear IP- and carbon-benefit-driven revenue path.

CarboSlag welcomes co-founder candidates regardless of gender age ethnic origin religion or belief disability sexual identity or any other characteristic. This is a search for the right partner to build the company with not a conventional hire.
