Job description

BTRY is a Swiss startup revolutionizing energy storage with its cutting-edge thin-film solid-state battery technology. We’re on a mission to power the future of electronics with high-performance, customizable battery solutions. As we scale our technology from development toward industrial production, we are looking for a motivated intern to join our Scale-Up Team.

If you are interested in battery technology, hands-on laboratory work, and turning innovative processes into reliable and scalable solutions, this role is for you.

Key Responsibilities

As part of BTRY’s Scale-Up Team, you will work closely with senior engineers and support the development, testing, and documentation of battery materials, cells, and manufacturing processes.

• Support senior engineers with laboratory experiments and scale-up activities.
• Perform electrochemical and material characterization and document the results.
• Support the planning and execution of Design of Experiments (DOE) studies.
• Collect, organize, and perform initial analysis of experimental data.
• Prepare clear experiment summaries, project reports, and presentations.
• Maintain accurate and traceable records of experiments, samples, materials, and results.
• Fabricate coin cells and prepare samples according to established procedures.
• Ensure that samples, data, equipment, and documentation are properly stored and organized.
• Support the maintenance of laboratory equipment, inventories, and standard operating procedures.
• Follow laboratory safety, quality, and housekeeping requirements.
• Contribute to the continuous improvement of experimental and scale-up workflows.

Your Profile

• Bachelor’s degree or higher in Materials Science, Chemistry, Chemical Engineering, Mechanical Engineering, Electrical Engineering, or a related technical field.
• Strong interest in battery technology, manufacturing, and process scale-up.
• Comfortable performing hands‑on laboratory work with attention to detail.
• Basic understanding of experimental design, data analysis, and technical documentation.
• Experience with coin‑cell fabrication, electrochemical testing, or battery materials is an advantage but not required.
• Familiarity with Microsoft Office or Google Workspace; experience with data‑analysis software is an advantage.
• Strong written and verbal communication skills in English.
• Organized, reliable, proactive, and comfortable working in a fast‑moving startup environment.
• Able to follow established procedures while raising questions and suggesting improvements when appropriate.

Formalities

• Job type: Full‑time internship (CHF 2,000 per month)
• Workload: 100% for 6–12 months
• Start date: As soon as possible
• Location: Dübendorf (primarily on‑site, with limited hybrid flexibility depending on the activities)
