Mechanical Engineering Intern (Summer Job – ASAP)
Are you a hands-on engineering student with a passion for thermodynamics? As our new Engineering Intern (ASAP, 2-3 months, 100%) in Zurich Wiedikon, you will be right in the middle of the action, tackling one of our most critical business challenges: optimizing our fridge fleet's cooling performance during the hottest season of the year.
- 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.
- Valid work permit or Swiss passport.
- Hourly rate of CHF 27.00
- Delicious Meals at Your Fingertips: Enjoy fresh, high-quality meals just steps away from your workspace – every day.
- Barista-Style Coffee & Premium Tea: Fuel your day with barista-style coffee and premium tea, thanks to our Gavetti machine.
- Work in a collaborative, friendly, and down-to-earth team based in central Zürich that values initiative and gives you the space to contribute your ideas.
- Take on a real, meaningful project at the center of our business, with the chance to see your solutions implemented across a live fridge fleet, not just in a report.
- Work closely with and gain direct exposure to our operations, technical team, and management.
