Firmware Engineer


£400 Outside IR35

Bright Purple are searching on behalf of a Scottish based Company a Remote working experienced Firmware Engineer for a short piece of work to bring up a newly developed wearable system.

We are looking for the engineer to be based in the local area. 

We are looking for support in migrating the wearable’s code base away from the Mbed ecosystem. In order to read raw data from Maxim’s sensor hub (MAX32664) and analog front end (MAX30001).

The current code base uses Mbed, so strong knowledge of this is essential, and we are looking to create an industrial version by re-rolling all functionality for the ARM M4F (MAX32630) architecture and giving us total control over all elements of the system.

A strong understanding of Mbed is a MUST, as well as experience of the ARM M4F architecture.

Strong C skills are essential, with practical knowledge of C++ being beneficial.

We are looking for someone who’s good at documenting.

We need someone who has used Git or a version control system (VCS) before and is comfortable collaborating that way.


The tasks that we need completed are: 

Port BLE firmware from the Maxim examples

* Finish I2C driver, there is an issue with incorrect register addresses for I2C read commands.

* Finish testing BMI160 (Accel and gyro)

* Build driver for MAX30001 sensor

* Build driver for MAX32664 sensor hub

* Build SPI driver

* Port MAX30205 Temperature sensor firmware from Maxim example (This works well so no need to redo other than make necessary changes for new IDE)
