Full-stack Developer / Backend Developer

Full-stack Developer / Backend Developer (M/F/D) stemys SA designs advanced software solutions in IoT and statistical data analysis, based on the latest modern web technologies. With Brütsch/Rüegger Tools, a century-old company, we combine technological agility and industrial solidity. Want to shape the connected industry of tomorrow? Join a team that innovates every day. YOUR MISSION: Produce quality code by making reasoned technical decisions by evaluating trade-offs (performance, maintainability, cost, time-to-market). Design and evolve the architecture of our developments with a long-term vision. Navigate between cloud and on-premises deployments, on Linux and Windows environments. Read, understand, and exploit technical documentation independently. Use AI tools thoughtfully: as a productivity and exploration accelerator, not as a substitute for understanding the code you deliver. Collaborate actively within the developer team and challenge technical choices in a good mood. YOUR PROFILE: You are an HES/EPF engineer (or equivalent) with good knowledge of software architecture. You have experience in Java and/or a good culture of object-oriented patterns. You know how to read dense technical documentation and extract what matters, demonstrating autonomy in your analysis. You are comfortable with web standards (REST, OAuth, OpenAPI) as well as containerization (Docker). You are curious, rigorous, and prefer to understand the "why" before coding the "how". You use AI on a daily basis, but you remain capable of explaining, challenging, and correcting what it produces. Experience in multi-tenant or distributed architecture as well as knowledge of time-series databases is a plus. Knowing how to deploy with Kubernetes is also an asset. WE OFFER YOU: The dynamism of a start-up allied with the solidity of a century-old company. Real architecture problems to solve — not repetitive CRUD. A young, varied work environment that values initiative. Flexible hours and the possibility of teleworking. A permanent employment contract. Access to continuous training platforms, and dedicated time for it. An opportunity to enrich your industry knowledge and discover new technologies. Modern work equipment and offices. Application deadline: Employment agencies please refrain. jpide4724b7jm jpit0834jm jpiy26jm
