At Flix, we offer a tech-driven environment where innovation meets real-world impact, with competitive pay, strong growth opportunities, and a culture of collaboration and ownership.

Were looking for a motivated and skilled Middle Software Engineer to join our Geo Information Systems team – Supply Division. We build and operate an end-to-end platform that ingests, processes, and visualizes real-time vehicle and ride data, providing valuable insights to both customers and internal users.

Youll work on some of Flixs most visible products, building backend services that process large scale streaming data and power real time experiences for millions of passengers every day. Our backend has recently been rewritten in Scala 3 around Kafka Streams, so youll be building on a modern foundation rather than maintaining legacy systems.

Youll join a well-staffed, friendly, and diverse team where engineers take ownership, share knowledge, and help each other grow. While our stack includes Scala, Kafka Streams, AWS, Kubernetes, and Terraform, we care more about strong engineering fundamentals, curiosity, and a willingness to learn than experience with any particular technology.

Help evolve our engineering practices by strengthening automated testing, expanding end-to-end test coverage, and improving the reliability of our delivery pipeline.

Take ownership of services throughout their lifecycle, from design and implementation to deployment, monitoring, and continuous improvement.

Work closely with a friendly, cross-functional team to solve complex technical challenges and deliver high-quality products.

Help shape our engineering culture through collaboration, knowledge sharing, and pragmatic decision making.
