Job description

The Ideal Candidate

We are looking for an Embedded IoT / Firmware Engineer to join our team and contribute to the development of our connected products.

This is a hands-on engineering role covering embedded firmware, sensors, connectivity, secure device provisioning, cloud integration and end-to-end product validation. You will work with real production IoT devices and be involved in both development and field deployment.

Job Description

Requirements:

At least 1 year of professional experience in embedded software or firmware development
Strong experience with C/C++ and production firmware
Experience with microcontrollers such as ARM Cortex-M and ESP32 / ESP-IDF
Experience with FreeRTOS or a similar RTOS
Experience working with industrial sensors, including temperature, pressure, conductivity, level and battery monitoring
Knowledge of ADC, I2C, SPI, UART and digital I/O
Experience with Wi-Fi, TCP/IP, MQTT and Bluetooth / BLE
Experience using debugging tools such as JTAG, oscilloscopes, logic analyzers and multimeters
Familiarity with STM32CubeMX, Python and Git
Knowledge of TLS, X.509 certificates and AWS IoT Core
Understanding of secure device provisioning, persistent storage, watchdogs, recovery mechanisms and field diagnostics
Fluent English is mandatory
Category B driving licence is mandatory
Willingness to travel to clients, mainly within Europe
Degree or equivalent background in Computer Engineering, Automation, Electronics or a related field

Your responsibilities:
You will be involved in the complete lifecycle of our connected devices, including:

Sensor acquisition, calibration and validation
Secure device provisioning and certificate management
MQTT telemetry and device communication
Persistent configuration and credential storage
Remote diagnostics and fault analysis
Firmware stability, recovery and maintainability
Troubleshooting across firmware, hardware, connectivity and cloud systems
End-to-end testing of connected devices
Supporting commissioning and field validation at client locations

This is not an Arduino or prototyping-only position. We are looking for someone who is comfortable working with production IoT devices, taking ownership of their functionality and diagnosing issues across hardware, firmware, connectivity and cloud environments.

Additional advantages:

Experience with OTA updates, secure boot, signed firmware, secure elements, industrial interfaces such as 4–20 mA / 0–10 V, cybersecurity-aware product development, manufacturing, commissioning or field deployment of connected devices is a strong advantage.
Knowledge of an additional foreign language is also an advantage.

Benefits:

Competitive compensation based on experience and technical expertise
Opportunity to work on real-world industrial IoT products, from development to field deployment
High level of technical ownership and involvement in product development
Professional development and continuous learning opportunities
International projects and collaboration with clients across Europe
Hands-on experience with embedded systems, sensors, connectivity and cloud technologies
Opportunities for travel and field deployment across Europe
Additional benefits to be discussed based on experience and role
