Embedded C/C++ Developer

Job Description

You will be working in a team developing and maintaining the firmware of our IoT devices. The main focus is on reliability and efficient resource usage.

Qualifications

• Bachelor’s degree in Computer Science (or strong foundation in CS fundamentals such as design patterns, data structures and algorithms
• Excellent C and C++11 skills
• Strong experience working with hardware and sensors
• Passion for simple, documented and safe code
• Writing asynchronous code
• Writing meaningful tests
• Git with feature branching
• Excellent team working and communication skills

A plus (one or more are required):

• Mbed OS 5
• CMSIS
• Motion sensors
• CoAP
• MQTT
• Network stack

Where we need your help:

- Help develop a C/C++ application based on ARM Mbed OS on a 32-bit MCU
- Application functionality: CoAP/LWM2M client, IMU to collect motion data and pass them to our classification algorithm which is running on the same MCU, cellular connectivity, battery-efficiency. Since we are using NB-IoT, the amount of data and transmission frequency are limited to approximately 100 bytes every 10 minutes
- CoAP, IMU and cellular libraries are already 95% complete, the main task now is making the whole package production-ready
- Know yourself around RTOS concepts like threads, queues and mutexes
- Debug low-level issues like stack overflow crashes, make sure that the board can recover from any problem which could be solved with a manual reset
- Improve power consumption by keeping the application components asynchronous (callbacks instead of polling) and by using the sleep functionality of the MCU and peripherals
- Make use of a full IDE like Eclipse CDT

Additional Information

A monthly gross salary of € 2.332 - 3.000 for full-time depending on your professional experience and qualification + Company PSP (Phantom Share Plan) for Top-Performers.
