• Your mission at Climeworks is to support the evaluation and development of sorbent structures for direct air capture.

• You work in an integrated team to perform lab-based evaluations, including adsorption characterization, accelerated life testing, and sample prototyping of novel filters for direct air capture.

• You test materials for CO2 adsorption behavior and mechanical reliability.

• You work independently on work packages to understand and/or improve mechanical properties of new materials, to improve test methods, and to evaluate new ideas quickly by means of rapid exposure tests.

• You validate, troubleshoot, and document the work you do clearly to communicate to others at Climeworks in the context of interdisciplinary development projects.

• You have a bachelor’s and/or working towards a master’s degree in mechanical engineering, process engineering, chemical engineering, materials science, or similar.

• You are available for a 6-month internship with start date preferably in August/September 2025 or shortly thereafter.

• You enjoy working hands-on in the lab or in the workshop, and you have some classroom or other experience with any of the following: characterization of porous materials (BET, Hg porosimetry, TGA, etc.), structural analysis (tensile/compression testing, FEM, etc.), adsorption characterization (breakthrough testing, DVS, etc.), or prototyping in a workshop.

• Familiarity with CO2 capture is beneficial but not required.

• You are eager to learn new concepts, skills, and tools that you might need to complete your assignments.

• You are reliable, motivated, solution-oriented, concise, and have a structured working style.

• You are fluent in English; knowledge of German or other languages is beneficial but not required.
