THE FELFEL TECHNOLOGY TEAM & YOUR IMPACT

Nice to meet you! A quick introduction on who we are: FELFEL is a fast-growing start-up in Zürich, Switzerland, who has revolutionized food in offices in the last 5 years. The product? An intelligent fridge that is placed in over 500 companies where employees can purchase food from the best local chefs via an app or badge. An awesome customer journey and the freshness of the food differentiate it from a traditional vending machine (see picture on www.felfel.ch).

Today, we are 100 employees with a strong vision on how to grow and make life better at the office, particularly with strong technology involved.

FELFEL’s 15 engineers develop the next-generation technologies that change how thousands of users consume food at offices. Our product needs to handle information at massive scale and make sure over 50’000 people get their meal of choice at any time of the day.

Your impact will have no limit: together with our CTO and our founder Emanuel and the management team, you will build the ground for our growth in the coming years and make sure our customers have an awesome experience with FELFEL.

OUR TECH STACK:

Our main backends are written in C# / .NET and Python 3, using the Django library (for web app and ORM). We have a diverse microservices landscape, which are written in Python 3 and are using flask + SQLalchemy as well as Django. Our fridges are running on a custom Android board running an Android application to serve the POS user interface. It interfaces with various peripherals via USB and GPIO (temperature sensor, NFC reader, door lock).

We run on Azure/Docker/Kubernetes and configure and auto-deploy our applications with helm and flux. Data is stored in Postgres and SQL Server and we use various queuing/messaging tools (Pusher, RabbitMQ, Kafka). For analytics and BI, we rely on Tableau and use logz.io’s ELK stack to analyze our application logs and telemetry.

THE CHALLENGE / YOUR ROLE:

Lead the design & implementation of our core back-end services, which allow us to manage the inventory of all our fridges in real time, orchestrate the fresh supply chain and sell products to our end customers. Every of the 500 fridges is stocked daily with approximately 50 different products with different shelf life. Drive the implementation of new forecasting algorithms and tooling which improve decision making for the Revenue Management team. In other words you are building the tooling to make sure our customers have the ‘perfect’ amount of food with a low amount of food waste. High availability: our systems run all day -you take responsibility for live productions systems with 24x7 uptime. Perform developer tests on your own code and peer code reviews as well as prepare strong documentations of your work. Develop tools for our internal teams (sales, support, operations, finance) to help run the business more efficiently. Continuously improve and maintain components & systems to ensure its functionality, scalability, uptime and security.
