Mechanical Engineering Intern (Summer Job - ASAP)

• Diagnose current fridge cooling systems across various site conditions and usage patterns
• Identify root causes behind cooling instability, from compressor performance and door-opening frequency to ambient heat load and airflow design
• Develop and propose effective solutions for each identified issue, ranging from quick fixes to long-term structural improvements
• Improve overall cooling stability, factoring in the real-world effects of climate change and rising office temperatures
• Ensure maximum food safety by keeping our fridges reliably within required temperature ranges, even under severe heat stress
• Work both hands-on (testing, measuring, and visiting fridges on-site) and strategically (conducting analysis, providing recommendations, and creating documentation)

• Currently studying engineering (mechanical, process, thermal, or a related field) with around 3 years of academic experience
• Solid understanding of thermodynamics, heat transfer, and mechanical systems
• Practical and curious mindset, with the ability to move fluidly between hands-on diagnostics and structured problem-solving
• Availability to commit to a 2–3 month project over the summer
• Fluency in either German or English; speaking both is a distinct advantage
• Non-smoker - we don't want you to smell like cigarettes, neither at work nor at customer meetings. After all, FELFEL is about good food.
