In one line

Freelance embedded engineer for client hardware projects, working across Linux boards and microcontrollers; fully remote, paid hourly, with a possible move to a salaried core role.

About the role

Suits someone who asks why before coding, reads a schematic with a critical eye, and knows that working on the bench is not the same as working in the product. Firmware here sits between hardware, mobile, cloud, QA and product.
