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.
As a Senior Java Backend Engineer you will be part of a team that focuses on automating and streamlining FlixTrain’s operational processes, creating internal tools that help teams manage a growing and increasingly modern fleet. You’ll join a small, collaborative team (6 people) with a strong sense of ownership and a pragmatic, low-bureaucracy way of working.
The team is part of the FlixTrain Tech division, which currently consists of three product teams and is set to grow significantly over the coming year, expanding to six teams as FlixTrain continues to scale its operations, fleet, and supporting technology. The complexity of our operations grows and so does the need for reliable, well-designed systems that reduce manual work, support regulatory requirements, and enable teams to operate efficiently at scale.
This role sits in a greenfield environment, where many systems are designed and built from scratch. Engineers are closely involved throughout the entire lifecycle: understanding operational challenges, contributing to architectural decisions, and ensuring high quality through solid testing practices. We value engineers who are curious about the business, eager to participate in discovery and problem framing, and comfortable navigating ambiguity.
Our Tech Stack: Java, Spring/Spring Boot, Kafka, MySQL ( RDS), MongoDB (DocumentDB), AWS, Docker, Gitlab CI, Kubernetes, Terraform, Datadog
