Embedded Firmware Engineer

Sweden Opportunity



The Firmware Engineer will be working with our customer-facing engineering team, other internal engineering teams and partners to define requirements from customer inputs, create interfaces to our force/pressure sensors, produce data calibration and linearization algorithms, and communicate data to other systems. The engineer will use his/her technical background to devise innovative solutions for these requirements and will have the opportunity to work with a variety of microcontroller architectures, though our primary targets are ARM Cortex core based. The Peratech Product and Solutions Development team is in central Stockholm and the postholder will be located there. The engineer will be part of a global solutions team, with colleagues and internal and external customers all over the world. Therefore, this job could include around 30 travel days a year internationally, especially to Asia.

Duties and Reponsibilities
