Full-Stack Software Developer

Are you a versatile problem-solver who wants to write software that impacts the physical world? As a Full Stack Software Engineer (100%) in Zurich, you will be at the core of our operations, building systems that touch everything from warehouse automation to customer-facing smart fridges.

YOUR RESPONSIBILITIES

• Take vague problems from non-technical colleagues and turn them into shipped solutions across our backend, web apps, Android app, or physical devices.
• Maintain the warehouse and supplier web apps used daily for inbound processing, picking, labels, and inventory.
• Develop our back-office internal tools, managing the backend and GraphQL API that run menus, deliveries, and customer sites.
• Manage the critical service connecting our automated picking lanes to the broader system to ensure seamless warehouse operations.
• Oversee the Android Point of Sale application running on hundreds of fridge devices and streamline the release process for the fleet.
• Integrate card payments, TWINT, our ERP, and other external partner systems securely.
• Drive production health by managing logs, alerts, careful feature rollouts, rollback plans, upgrades, tests, and code cleanup.
• Split complex features into manageable pieces and thoroughly review pull requests from other engineers.
• Participate in the on-call rotation, debug live issues alongside the operations team, and occasionally visit the warehouse to test changes on-site with end-users.

YOUR PROFILE

• Proven production experience in at least one typed backend language (such as C#, Java, Kotlin, Go, or TypeScript) and one modern frontend framework.
• Track record of successfully owning software in production, including on-call duties, debugging from logs, and resolving live issues while users wait.
• Familiarity with or willingness to dive into C#, TypeScript, Android, and Kotlin.
• Prior exposure to hardware, IoT, edge devices, payments, logistics, retail operations, or Odoo environments is highly advantageous.
• Demonstrated ability to ship features in an unfamiliar tech stack and learn new systems at a rapid pace.
• Strong passion for collaborating directly with end-users, including warehouse and operations staff, rather than exclusively with other engineers.
• High degree of curiosity and a proactive mindset to take full ownership of problems from end to end.
• Fluent English communication skills (written and spoken); knowledge of German or French is a plus.
• 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

• Lots of delicious food, just a few steps away from your desk - we make your gastronomic dreams come true
• Best barista coffee and tea for the whole team, thanks to our innovative Gavetti coffee machine
• 5 weeks holiday per year, as well as the chance to buy an extra week of vacation
• Two full weeks of ‘work from anywhere’ per year to bring more variety to your work day
• We care about your future with an above-mandatory pension fund
• New parents get 16 or 3 weeks, respectively, of fully paid parental leave. We also support the return to work by making a generous financial contribution to childcare until the child reaches kindergarten age.
• We encourage our employees to use public transport by covering your half-fare travelcard
• Great team events, such as our well-known FELFEL Summer Outing
• Stay active and healthy with our weekly sports sessions
