R&D Intern

To limit global warming to 1.5°C, the IPCC states that net-zero emissions must be achieved by 2050. In addition to substantial emission reductions, this goal can only be reached through the global deployment of CO₂ removal solutions at the scale of billions of tons.

Neustark is a leading provider in this rapidly growing market: we have developed a solution to store CO₂ from the air in recycled mineral waste such as demolished concrete or incineration bottom ash.

Neustark has already deployed storage site in Switzerland and across Europe, storing CO₂ from the atmosphere on a daily basis. We are currently scaling our activities to significantly increase our storage capacity.

We are an international team working primarily from Switzerland, enabling permanent CO₂ storage for a better future for all generations on our planet.

What R&D does at neustark: In the R&D team, we continuously work on optimizing our technology and exploring new storage approaches. You can actively contribute to the latest developments and be involved in all phases of a project, from concept idea to testing. In addition, we generate laboratory data on various material streams for other departments. We also use Python-based modeling to simulate and optimize storage site performance..

What your job could look like:

• You help drive forward current developments at neustark, including areas such as construction, process engineering, electrical engineering, programming, or manufacturing.
• You carry out test series with developed prototypes in the field.
• You take responsibility for our laboratory, where we test customer materials for their CO₂ storage potential.
• You help integrate and interpret the resulting data into a database.
• You conduct internal lab campaigns to explore additional material streams beyond recycled concrete as CO₂ sinks.
• You continue developping our model to further understand and optimize our storage sites.

What’s in it for you:

• Sustainability mission: Together, we create a tangible climate impact through permanent CO₂ storage and removal.
• Start-up atmosphere with strong financial backing: You benefit from flat hierarchies, fast decision-making, and strong investor support.
• Hybrid work culture: We value collaboration and flexibility, with working time split between our Swiss hubs in Bern and Zurich, and remote work depending on job needs.
• Teamwork: We work closely across teams to make a real impact, regularly aligning on goals and celebrating successes together.
• Professional environment: A fast-growing organization with many opportunities for responsibility and development.
• Employee benefits:
• Contributions to public transport and your mobile phone
• Fair vacation entitlement, including local public holidays and country-specific arrangements
• Employee-led learning lunches, yoga, and running sessions

What we’re looking for:

• You are pursuing or have completed a degree in mechanical engineering, process engineering, electrical engineering, or a related field. (ETH/EPFL or similar)
• You are hands-on and enjoy practical work, including outdoor activities.
• Collaboration is important to you, including with external partners and suppliers.
• You are motivated, quick to learn, and eager to take ownership of projects.
• You have some knowledge in coding (Python).
• You speak English; German and/or French are preferred.

Work location:

On average, 3-4 days in the Bern area and the rest flexible between our Bern or Zurich offices or home office.
