🏢 Summary: Join a cross-functional product team to build and operate scalable, high-throughput Java backend solutions for eCommerce core processes. The role combines hands-on architecture, quality ownership and product discovery, with daily use of AI-assisted and agentic coding workflows. 🗂️ Requirements: Java 21+ backend experience, Reactive or asynchronous programming experience, Virtual threads experience, Distributed backend systems experience, Event-driven messaging experience, CI/CD and automated testing experience, Code review and observability experience, AI coding tools and agentic workflow experience, Product-oriented cross-functional collaboration 📃 Skills: Java, Vert.x, Reactor, Kafka, CI/CD, DDD, SOLID, Claude, Copilot, Scrum, Kanban 🏢 Description: We are one of Switzerland's leading online shops in both B2C and B2B - a combination that is nearly unique in Europe. Behind it stands one of the most modern logistics operations on the continent: highly automated, scalable and with further growth potential. Here you do more than build software. You bring your personality, actively shape the department and help define the eCommerce of tomorrow. The role Join a cross-functional product team and build scalable solutions with real impact for our customers and core business processes. You bring curiosity, team spirit and a genuine appetite for learning - and you take part in shaping not just the implementation, but the architecture, quality standards and the question of what should be built in the first place. What to expect A collaborative cross-functional product team with a hands-on Team Lead, a Product Manager and several T-shaped Full-Stack Engineers who share ownership together. You work in Scrum or Kanban depending on what fits the team. Engineers roll up their sleeves in refinement and actively contribute to architecture and product decisions - not just implementation. Plenty of room to shape high code quality within your team and across team boundaries. Enough legacy, complexity and grown structures to give you real opportunities to make things meaningfully better - one step at a time. What you bring We are a good match if you: Java & Backend Depth Bring deep, hands-on experience with Java 21+ - including modern language features such as records, sealed classes, pattern matching and structured concurrency Have practical experience with reactive or asynchronous programming models - with Vert.x, Project Reactor or comparable toolkits; you understand the non-blocking programming model and know when to apply it Have worked with Java virtual threads (Project Loom) and understand how they change concurrency models in practice - not just in theory Have built and operated distributed backend systems at scale - ideally in eCommerce or comparable high-throughput domains Are comfortable with event-driven communication patterns (Kafka, messaging systems) and understand the trade-offs between synchronous and asynchronous approaches Engineering Practices Have lived modern engineering practices in your daily work: CI/CD, automated testing, decoupling, code reviews and observability See concepts like DDD, Clean Architecture, Event-Driven Architecture, SOLID, feature flags and dependency injection as practical tools - not buzzwords - and apply them with pragmatism and judgement Are a strong advocate of "you build it, you own it" and have experience in environments that release multiple times per day Guide the team on code quality and meaningful testing practices - not coverage as a goal in itself, but tests that catch real bugs AI / Agentic Coding - a core expectation, not a nice-to-have Use AI coding tools - such as Claude Code or GitHub Copilot - as a natural part of your daily workflow for code generation, test writing, refactoring and documentation Go beyond autocomplete: you actively explore agentic workflows such as automated PR review, scaffolding, and multi-step code generation - and you evaluate their output critically before committing Understand the risks: you know that AI-generated code can accelerate technical debt and erode understanding if not reviewed carefully, and you enforce review standards accordingly Help introduce and shape AI tooling adoption within the team - sharing what works, what does not and where the limits are Collaboration & Product Mindset Enjoy sharing knowledge through pair programming, whiteboard sessions and code reviews - and actively help raise the engineering level of the team Like working closely with Product Managers and genuinely want to understand the problem being solved - you help shape requirements and think from a user and business perspective Value real agility: short iterations, fast learning, active feedback loops and data-informed decisions Are a warm communicator who values an open learning culture, builds personal connections within the team and does not take themselves too seriously We are probably not a good match if you: Prefer frameworks like SAFe or projects that start with a fixed requirements document Have worked primarily in heavily regulated environments without experience in a fast-moving, product-oriented setup with distributed systems Are most comfortable in models where infrastructure, backend, frontend, testing and product thinking are kept strictly separate Prefer to receive requirements fully formed rather than shaping them together with Product Management See AI tools as a threat or a gimmick rather than a genuine productivity multiplier worth mastering See ongoing learning primarily as the employer's responsibility rather than your own intrinsic motivation Are more frustrated than energised by imperfect systems - spoiler: we are not there yet Keep work and good humour strictly apart
