Who You Are

You’re a self-motivated team player who wants to influence your own development. It is natural for you to be proactive in working with your teammates and other parts of the organization. You like sharing your know-how to help the whole team advance. Bringing in new ideas to improve existing products with new functions and cost optimization is important to you. You’re looking for a company where you have the opportunity to pursue your interests across functions and geographies—where a job title is not considered the final definition of who you are, but the starting point.

• 10+ Years of Technical & Management Experience: Must demonstrate:

• Management: Proven history of direct oversight of global teams, including talent acquisition, performance management, and strategic program delivery.

• Technical: Continuous, active, hands-on architectural leadership in high-end embedded systems.

• Expert-Level Medical Instrument Control: Proven mastery in designing and architecting software for Real-Time Linux (Debian/Yocto) environments, specifically for complex, high-precision laboratory or diagnostic medical instruments (IVD).

• Advanced Modern Systems Stack: Deep technical proficiency in C++ and Rust for safety-critical applications, paired with experience architecting distributed internal device messaging using RabbitMQ.

• Specialized Middleware & Design Patterns: Extensive experience with Asynchronous programming (async/await), the Actor Model framework, and Event-Driven Architecture within an embedded context.

• Ecosystem & Tooling: Expert knowledge of Linux Docker, Development Containers, and common Rust frameworks (e.g., tokio, serde, sqlx).

• Hardware-Software Integration: Hands-on experience with CAN bus and the full-lifecycle SW/HW development of IVD instruments within highly regulated environments (ISO 13485/IEC 62304).
