Radical Dot is hiring a Technology Expert (Process / Chemical Engineering) (m/w/o) to support the development and scale-up of our cutting-edge technology for converting 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 looking for a hands-on and adaptable team member who thrives in a dynamic environment. You will play a critical role across modeling, process design, and detail engineering for our demonstration plant (100-200 kg/day input plastic), contributing directly to the success of our mission to address the global plastics crisis.

Tasks

Providing expert knowledge in the development of our technology, with a focus on our demonstration unit designed to process approximately 100–200 kg of plastic waste per day on a 24/7 basis. This includes:

Leading advanced process modeling using Aspen and/or reactor fluid dynamic tools to enhance efficiency and performance.
Taking ownership of key technical challenges and driving problem-solving efforts.
Leading the configuration and design of the reactor system.
Supporting the optimization of the entire demonstration unit from end to end.
Contributing to safe, stable, and efficient operations at all times.
Refining chemical engineering designs to deepen process understanding and support strategic decision-making.
Initiating, establishing, and maintaining strategic industry collaborations and partnerships, including scouting and evaluating new opportunities.
Contributing to the mentorship and growth of a high-performing chemical engineering team. We aim to scale to a team of 5–10 engineers over the next 3 years.
Participating in hands-on pilot plant construction.
Collaborating closely with the broader Engineering and Science team in a unified, cross-functional “one-team” culture.

Requirements

10 years of experience in chemical engineering including industry experience (chemical or petrochemical industry). Experience in a start-up environment is a plus.
Team leadership including experience with supervising and growing a team of chemical engineers, mentoring and developping them.
Proven track record in process scale-up from lab to industrial scale, including detail engineering and reactor design, both from a technical and project management stand point (e.g., budgeting and timelines). Experience in system scale up may include scaling of reactors/reactions, separation, or distillation units in the chemical industry.
Problem anticipation and creative problem-solving skills.
Ability to navigate scaling parameter and quantitative determination such as mass transport, rheology/viscosity, kinetics, filtration, distillation, recrystallisation.
Familiarity in process modeling and simulation (e.g., Aspen Plus or equivalent tools) and reactor fluid dynamics is required. Strong expertise is a plus.
Familiarity with chemical recycling, high-pressure reactions, oxidation chemistry, or corrosive environments is an advantage.
Proficiency in English is required, German is a plus.
