- A small, collaborative, and flexible team environment
What you''ll bring:
- Proven experience in embedded systems design and development
- Strong C/C++ skills for microcontrollers, with the ability to work at low level
- Ability to bridge hardware and software, collaborating effectively with electronics engineers
- Confidence in leading projects and mentoring others, without losing your hands-on edge
- Flexible, adaptable approach to work-happy to pick up new tools, technologies, and problem domains
This is the perfect role for a seasoned principal embedded systems engineer who thrives on variety, values teamwork, and enjoys both the leadership and technical sides of product development.
