Senior Firmware Engineer

Firmware for sensor product and application solutions

• Application solutions with Flusso sensor products (semiconductor/MEMS components) require firmware that runs on a standard microcontroller (MCU) or a processor core in an ASIC.

Sensing solution firmware development responsibilities include

• Design and development of code that implements functionality and interfaces of the agreed Solution Architecture.
• Participate in safety DFMEA and HAZOP processes
• Optimisation of code and creation of builds for sensor component and application circuit variants.
• Porting firmware to new target processors and/or application designs

Qualification, knowledge, skills and experience

• A bachelor’s degree in an engineering or science subject is a prerequisite.
• Essential knowledge, skills and experience:
• Development of real-time firmware – in C – for ARM-based microcontrollers or ASICs, typically using ADCs, DACs and interfaces such as I2C, SPI and CAN.
• One or more of the main microcontroller families such as STM32 and EFM32
• Use of source code management systems (we use git)
• Use of tools such as Keil, IAR, STM32CubeMX and Eclipse/gnu.
• Debugging using JTAG interface adapters and test equipment such as oscilloscopes and logic analysers
• Automated testing of firmware builds for multiple targets, covering new product solutions, new features, performance enhancements and regression testing.
• Regression testing updates to existing sensing solutions on multiple targets
• Programming in Python
• Working to software lifecycle quality processes in an ISO9001 framework
• Not essential, but would be an strong advantage:
• Development of firmware for functional-safety applications
• Development of firmware specifically for sensing solutions or applications
• Development of firmware for automotive or medical applications
• Experience with continuous integration (CI) systems
• Development of Windows 11 GUI applications in C# or Python (e.g. PyQT)
