THE ROLE & THE TEAM As a Senior Software Engineer, you will be part of an expert team of software engineers and applied scientists working towards keeping the delivery time promise for all Zalando customers. Your focus will be the design, development, and improvement of a core software system that drives algorithmic order prioritization and fulfillment optimization in all Zalando warehouses. In this role, you will face three significant challenges: ensuring the system adheres to the latest software engineering standards, gaining a comprehensive understanding of order processing systems to identify opportunities for improvement, and ensuring the software design supports the integration of complex multi-objective algorithms.

If you have a passion for creating scalable software systems and solving complex problems, we want to hear from you. This is a unique opportunity to make a real impact and help drive the success of our business.

WHAT WE’D LOVE YOU TO DO (AND LOVE DOING)...Take ownership of the design and implementation of our software framework to cater for the increasing scale and load, and be the driving force behind its success.

Deliver end-to-end solutions and set the standard for the entire development cycle, including requirements engineering based on deep domain & business understanding, prototyping, implementing production software, as well as testing and operating the highly available production system.

Navigate technical coordination across multiple teams and stakeholders, balancing our team’s needs with upstream/downstream constraints.

Be a key driver of operational excellence: own incident response, build team playbooks, and ensure production stability for a business-critical system.

Collaborate closely with our applied scientists to mutually influence and understand system constraints and opportunities, and take part in shaping the future of our system.

Think abstractly and discover correlations between problems, methodologies, and solutions.

Promote and support an inclusive culture and diverse team environment, fostering a positive and productive work environment for all team members.

WE’D LOVE TO MEET YOU IF...You have ~5 years of relevant industry experience as a senior engineer developing for JVM-based platforms, with a strong understanding of mathematical and computational concepts.

You have hands-on experience in microservices architecture and patterns, Spring Boot, REST, Kubernetes, Event Streaming Platforms, architecture documentation, data and API specifications (e.g. OpenAPI), quality assurance and testing methods. Proficiency with Kotlin, and Python are considered a plus.

You approach software design strategically and aim for reducing complexity and producing designs that are easy to maintain and extend.

You have prior experience in operations and incident response — you understand that production stability is a team sport.

You are excited about working in a setup that requires a deep domain understanding (e.g., how our logistics order processing works), basic mechanisms of our optimization algorithms, as well as operations research methods.

You are a team player who thrives in an agile and cross-functional environment, and is passionate about fostering a positive and productive work environment.

You are fluent in English.
