We're looking for a Software Engineer (Kotlin, Java) with strong Kotlin (or Java and willing to learn Kotlin) skills to join our Capacity Management team in the Demand Division. The Capacity Management team builds and runs the systems that determine how seats are allocated, priced, and managed across Flix. We handle high-throughput, real-time data pipelines and event-driven microservices that keep operations running smoothly, even under unexpected conditions. 

As a Software Engineer at Flix, you can make an impact by working on systems that directly impact how millions of passengers book seats and how Flix optimizes capacity across its global network, at scale, in real time.

• Uphold engineering quality through code reviews, testing, and thoughtful design decisions 
• Use AI tools such as Claude Code and Copilot conscientiously to assist in faster and higher-quality development
• Take ownership of features end-to-end, from design and implementation through to production, while also contributing to the continuous improvement of our existing systems

About You

• 3–5 years of experience building production-grade backend systems, with Java or preferably using Kotlin

• Understanding of Kafka-like message brokers and streaming patterns 
• Hands-on experience with event-driven architecture principles (event sourcing, CQRS) applied within a microservices ecosystem  
• Familiar with cloud providers (especially AWS) 

We recognize that everyone carries a unique set of valuable skills and experiences. If you think you could have an impact even though you don't meet 100% of the requirements, we still encourage you to apply. We want to hear from you!
