Senior Software Engineer Fullstack – AI Focus

Required skills: Software Architecture, Distributed systems, Java, CI/CD, Domain-Driven Design (DDD), AI Engineering, Automated Testing, Clean Architecture Senior Software Engineer Fullstack – AI Focus We are among the leading online shops in Switzerland in both B2C and B2B – a combination that is unique in Europe. Behind this is one of the most modern logistics systems on the continent: highly automated, scalable, and with great potential for expansion. With us, you don’t just develop software. You bring your personality, actively help shape the department, and influence the e-commerce of tomorrow. What to expect A small cross functional team with really good engineers who work pragmatically and with a lot of drive on one of the most relevant topics of our company. A Project built primarily in Java – and a large-scale scaling problem that you can really sink your teeth into (in the best sense). A pragmatic, agile setup with a Product Manager, Team Lead and about 4-5 Engineers. You will have a lot of direct contact with the business, refine requirements yourself, and actively contribute to architecture, product, and UX questions. Lots of creative freedom and the chance to have a real impact on the entire company - end to end, from backend architecture to the interface users actually touch. What you bring with you We match if you bring 10+ years of solid experience in modern, product-oriented software engineering and have already worked on complex, distributed systems – ideally in e-commerce or comparable domains. Benefit if you know how to process big data amounts. are strong in Java (preferred) or comparable Languages. develop AI-first: 90%+ of your code is created with AI – and you know exactly how to maintain quality and control. build systems that work for AI: In-code ADRs, agent files, MCP integrations, multi agent setups, or autonomous loops are not foreign words to you but everyday terms. consistently align your processes with AI: spec-driven refinements, automated PRs, AI-supported reviews – while confidently managing the mental load of parallel work. rely on strong, deterministic quality gates: tests, linting, and static code analysis are for you the foundation that makes AI-generated code trustworthy. live architecture: you use DDD, Clean/Hexagonal Architecture, Event-Driven Design, and decoupling sensibly and pragmatically – including SOLID principles. are a strong advocate of “You build it, you own it” – including infrastructure and CI/CD, which you build and operate yourself. persevere through complex problems and have the resilience to see topics through to success. are a warm-hearted communicator who values an open learning culture, enjoys building personal connections within the team, and can laugh at good jokes. We probably don't fit well together if you see AI as a scary black box and prefer not to work with Claude Code & Co. prefer frameworks like SAFe or projects that start with a requirements specification. have mainly worked in highly regulated areas – without experience in a fast-paced, product-oriented environment with distributed systems. feel more comfortable with role models where infrastructure, backend, frontend, testing, and product thinking are clearly separated. see continuing education primarily as the employer's responsibility – instead of learning on your own initiative, on the job, at an evening event, or with a good book. are more frustrated than motivated by imperfect systems – spoiler: we are not there yet. strictly separate work and good mood :) Ready to build bold AI-first solutions, take real ownership, and shape the future of e-commerce with us? Then we’d love to hear from you.
