Senior Software Engineer – AI Focus

Senior Software Engineer – AI FocusWe 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 expectA small cross functional team with really good engineers who work pragmatically and with a lot ofdrive 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 teethinto (in the best sense).

A pragmatic, agile setup with a Product Manager, Team Lead and about 4-5 Engineers. You will havea lot of direct contact with the business, refine requirements yourself, and actively contribute toarchitecture, 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 youWe match if youbring 10+ years of solid experience in modern, product-oriented software engineering and havealready worked on complex, distributed systems – ideally in e-commerce or comparable domains.

Benefit if you know how to process big data amounts.are backend-heavy but genuinely fullstack: strong in Java on the backend, and comfortable enoughin React on the frontend to own a feature end-to-end, with a good eye for UX (Java/React are a niceto-have, not a strict requirement).develop AI-first: 90%+ of your code is created with AI – and you know exactly how to maintainquality and control.build systems that work for AI: In-code ADRs, agent files, MCP integrations, multi agent setups, orautonomous loops are not foreign words to you but everyday terms.consistently align your processes with AI: spec-driven refinements, automated PRs, AI-supportedreviews – while confidently managing the mental load of parallel work.rely on strong, deterministic quality gates: tests, linting, and static code analysis are for you thefoundation that makes AI-generated code trustworthy.live architecture: you use DDD, Clean/Hexagonal Architecture, Event-Driven Design, and decouplingsensibly and pragmatically – including SOLID principles.are a strong advocate of “You build it, you own it” – including infrastructure and CI/CD, which youbuild 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 personalconnections within the team, and can laugh at good jokes.

We probably don't fit well together if yousee 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-orientedenvironment with distributed systems.feel more comfortable with role models where infrastructure, backend, frontend, testing, and productthinking are clearly separated.see continuing education primarily as the employer's responsibility – instead of learning on your owninitiative, 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.
