• Solid understanding of microcontroller-based systems; experience with STM32 platforms is a plus.
• Proven ability to design software for resource-constrained environments with performance-critical requirements

• Experience with source control systems (e.g., Git), automated testing, and debugging using lab equipment.
• Familiarity with Zephyr RTOS and/or other real-time operating systems is a plus.
• Knowledge of wireless protocols and IoT technologies is desirable.
• A proactive, solution-oriented mindset and ability to thrive in a collaborative, agile team environment.
• Fluency in Portuguese and professional working proficiency in English, both written and spoken.

What matters to us

We understand not only the power of the visible, but also the
invisible. Like light, diversity is intangible, but it is
perceptible. We value the uniqueness of every person and see this
as a driver of innovation. Qualified applicants will be considered
regardless of, for example, origin, skin color, gender, religion,
age, sexual orientation, gender identity/expression or disability.

As the contact person for this position, a great candidate
experience is important to me! I will reach out to you within 7
