Our client is the world’s biggest watchmaking conglomerate. The client makes movements, both quartz and mechanical, fully assembled or in kit form, for brands in its own group and for external clients. It’s a powerful, largely independent, multifaceted company.

Our client designs and manufactures mechanical and automatic watches, watch movements and watch prototypes. Although the company produces finished watches and movements, the client specializes in the production of prototypes movements used both in watches of sister subsidiary brands and in the watches of competitors, including brands owned by Compagnie Financière Richemont S.A. and others.

We are looking for a Senior Embedded Software Engineer to join the core team working on the new Connected watch development (3rd edition), which will be released to the market Q1 2027. In this role, you will work on firmware development for advanced wearable/embedded hardware, utilizing cutting-edge toolchains and modern embedded frameworks.

Key Responsibilities

• Design, develop, and maintain embedded software (firmware) for ARM Cortex-M architecture (STM32, nRF54).
• Participate actively in SAFe Agile ceremonies, collaborating closely with mobile developers, testers, and product owners.
• Write clean, maintainable C/C++ code, leverage modern AI tools (GitHub Copilot) in VSCode, and contribute to automated test workflows using Python.
• Drive feature delivery from low-level hardware abstraction to application-level logic.

Soft Skills & Team Fit:

• Ability to communicate clearly and build strong relationships within a cross-functional feature team.
• Comfortable working in a remote environment, taking ownership of tasks, and proactively solving hardware/software integration roadblocks.
• Solution-oriented mindset with strong analytical skills when debugging complex embedded systems.
• Willingness to integrate AI assistants (like Copilot) and modern dev-ops practices into daily work.

What We Offer

• Work with modern hardware platforms and bleeding-edge embedded technologies.
• Flexible remote work options with structured, predictable travel for SAFe PIP events.
• Collaborative and transparent engineering culture within a well-balanced Agile team.
