Separation & Purification Process Lead (Chemist / Scientist)

Your Mission

Radical Dot is hiring a Separation & Purification Process Lead (Chemist / Scientist) (m / w / o) to drive the development of the downstream processing and product recovery sections of our cutting-edge chemical recycling technology.

Radical Dot transforms mixed plastic waste into high-value chemical building blocks. Moving beyond traditional methods like pyrolysis and gasification, we are pioneering a sustainable and cost-efficient solution for the chemical industry.

As an early-stage start-up, we are seeking a hands-on and adaptable leader who thrives in a dynamic lab environment. You will play a critical role in leading and delivering targeted research projects, contributing directly to our mission to tackle the global plastics crisis.

Tasks

Responsibilities will include :

• Lead the development of the downstream processing section of the chemical recycling technology, including associated R&D activities
• Design and execute experimental programs to characterize product streams, phase behaviour, and solubility regimes relevant to separation
• Develop and scale separation concepts such as flash separation, precipitation, and crystallization with a focus on economic viability
• Own the conceptual and detailed design of filtration systems, aligning process constraints with appropriate equipment selection
• Evaluate and implement alternative process flowsheets to improve performance, operability, and robustness
• Partner with analytical and process teams to define and design suitable characterization methods for solid and liquid phases across the process
• Working closely with the Engineering and Science teams in a collaborative "one-team" mindset to deepen the scientific understanding of our chemistry and optimize our processes
• Supervising one or more students contributing to the project's overall objectives, if opportunities arise

Radical Dot is a climate-tech startup based in Munich, Germany, which was established in 2024, by Alex & Andi . Our technology transforms non-recyclable plastic waste into essential chemical building blocks (e.g., acetic acid).

We are hosted in the TU Munich Venture Labs ChemSPACE, where we validated our proof of concept, further improve the technology and take steps to scale up. We have submitted

our first patent application and run several reactor systems, putting us at approximately TRL 4.

We closed a 2.7m€ Pre-Seed round in Q1 2025 to scale the team and technology.
