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 daily.

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.
• Actively collaborate within the developer team and challenge technical choices in a good mood.

###

YOUR PROFILE: ###

• You are a HES/EPF engineer (or equivalent) with good knowledge of software architecture.
• You have experience in Java and/or a good understanding 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 you prefer to understand the "why" before coding the "how".
• You use AI daily, 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 combined with the solidity of a century-old company.
• Real architectural problems to solve - not repetitive CRUD.
• A young, varied work environment that values initiative.
• Flexible hours and the possibility of teleworking.
• An indefinite duration 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.
