Jobbeschreibung

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.

We’re looking for a skilled Senior Software Engineer to join our high-impact team Orion – Supply Division and help us shape the future of mobility operations. Our team owns a critical product at the heart of the Flix ecosystem — optimizing how Flix coordinates with Mobility Partners to keep millions of passengers moving across the globe.

We maintain and continuously evolve a mature, stable product while simultaneously pushing it forward — tackling complex architectural challenges, reducing manual processes, and exploring AI-driven solutions. You'll take real ownership, contributing not just to code, but to product and technical decisions that directly impact the business.

If you enjoy working in a collaborative, self-organized team where engineers have a genuine voice, and you're excited about solving complex problems at scale — this might be the right next step for you.

Our Tech Stack

• Backend development: Java, Spring / Spring Boot, Kafka
• Databases: MongoDB (DocumentDB), MySQL / Postgres (RDS), Redis (Elasticache)
• Cloud services: AWS, S3
• DevOps / Infrastructure: Kubernetes, Docker, Gitlab CI, Terraform
• Additional tools and technologies: Microservices architecture, Event-driven systems, Distributed systems design and implementation

About The Role

• You’ll collaborate with a distributed, self-organized, cross-functional team, taking full ownership of the development process and technical decisions.
• You’ll have the opportunity to design new products from the ground up while continuously improving existing ones, with room to explore and implement cutting-edge technologies.
• Drive the development process in an Agile environment, placing our users at the center of each solution you and your team create.
• Lead technical decisions not just within your team, but across teams, improving technical excellence through collaboration and lateral leadership.
• Help define and deliver products that optimize the coordination between Flix and Mobility Partners, enhancing efficiency and reducing manual tasks.
• Be part of a team building a critical product within the Flix ecosystem—solving complex challenges due to product’s diverse user base and Flix’s global presence.

About You

• 6+ years of experience as a Software Java and/or Kotlin Engineer, with knowledge of distributed systems, including Spring/Spring Boot, Kafka, MySQL/Postgres, Redis, MongoDB and S3.
• Willingness to work with both Java (for existing products) and Kotlin (for new ones).
• Experience in making architectural decisions, and writing clean, performant, well-tested code.
• Autonomy and ownership in solving technical challenges, as well as strong communication skills when working with a distributed team.
• A strong product mindset, with a passion for user experience and a data-driven approach to decision-making.
• Experience in coding with AI.
• Fluent in English (upper-intermediate or higher).

Nice-to-haves

• Experience with DevOps and infrastructure: Kubernetes, Docker, Gitlab CI, AWS, Terraform.
• Familiarity with data engineering (ETL, Snowflake).
• Ability to teach people, share knowledge and experience, explain complex things in plain language, mentor, and provide constructive feedback.

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!

What We Offer

• Travel perks: 12 free Flix vouchers + 12 discount vouchers for friends & family.
• Work from (M)Anywhere: Depending on your role, work from another location for up to 60 days per year.
• Hybrid work model: We are an office-first company, but we offer flexibility to balance work and life.
• Wellbeing support: Access confidential 1:1 counselling, courses, and stress management for yourself and up to four family members.
