Project Engineer Intern - Cooling Optimization (ASAP)

IN SHORT

Are you a hands-on engineering student who enjoys a mix of deep analytical work and getting out of the office to solve real-world problems? As our new Project Engineer Intern (ASAP, 2-3 months, 100%) based in Zurich Wiedikon, you will be right in the middle of the action. Balancing your time between our office and on-site field visits, you will investigate root causes and optimize the performance and reliability of our smart hardware fleet across Switzerland.

YOUR RESPONSIBILITIES

• 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)

YOUR PROFILE

• 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.

OUR BENEFITS

• 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.
