Job Summary
What you will do
We are looking for a Firmware Engineer to join our engineering team and contribute to the development of embedded firmware used in securitycritical systems deployed worldwide.
In this role youll work on realworld embedded products collaborating closely with hardware software and systems engineers. Youll be involved throughout the product lifecyclefrom development and debugging to supporting production and continuous improvement.
This is a handson technical position suited to an engineer who enjoys practical problemsolving and building reliable wellengineered embedded solutions.
How you will do it
Embedded Firmware Development
- Design develop and maintain firmware for embedded systems primarily in RTOSbased environments
- Implement and debug multithreaded firmware using RTOS primitives such as semaphores queues and signals
- Develop finite state machines to ensure predictable and robust device behaviour
- Interface firmware with MCU peripherals and internal communication protocols including SPI and I²C
- Apply secure coding practices and contribute to firmware developed with security considerations in mind
Networking & Security
- Contribute to embedded networking functionality using standard concepts such as TCP/IP and client/server communication
- Work with existing secure communication technologies (e.g. TLS) and common cryptographic algorithms
- Support integration with accesscontrol communication standards such as OSDP
Smart Card & RFID
- Support firmware interacting with smartcard and RFID technologies
- Work with industry standards such as ISO 14443 and ISO 15693
- Assist with maintaining compatibility with existing and customerspecific card technologies
Hardware Interaction & Debugging
- Work alongside hardware engineers using schematics and system diagrams
