Job technologies
Your role in the team
- You write firmware that ends up in real products: IoT sensors, connected devices, mechatronic systems, for clients across energy, industry, mobility, and deep tech.
- You own the full embedded stack: from microcontroller bring-up and protocol implementation to cloud connectivity and a working prototype.
- You bridge hardware and software on projects where both matter, working closely with mechanical engineers, electronics designers, and clients.
- Develop and own firmware for connected devices (ESP32, STM32, Nordic), from first boot to working prototype.
- Implement and debug digital communication protocols (I2C, SPI, UART, CAN, BLE, WiFi, NB-IoT) across client projects.
- Integrate embedded systems with cloud backends and APIs.
- Collaborate directly with hardware engineers on bring-up, validation, and hardware-software integration.
- Set up development environments and tooling (Linux, Docker) that the wider project team can build on.
Our expectations of you
Qualifications
- Strong C/C++ skills for embedded systems; you're comfortable writing production firmware, not just examples.
- Working knowledge of digital protocols (I2C, SPI, UART, CAN) and wireless connectivity (BLE, Wi-Fi, NB-IoT).
- Comfortable in a Linux development environment—you set it up and maintain it.
- Ability to work independently across hardware and software boundaries.
- Nice to have: Python for test scripts or automation tooling.
- AWS or other cloud setup for IoT data pipelines.
- Docker for the development environment or build tooling.
- Eagerness to learn new tools and approaches.
- Comfort with ambiguity; hardware projects rarely go exactly to plan.
- Ability to work independently while staying connected to the team across offices.
Experience
- Hands-on experience with microcontrollers (ESP32, STM32, Nordic, or similar).
- PLC programming or industrial automation experience.
What we offer
- You'll own real products, not tickets.
- You'll be the firmware lead on client projects, from the first firmware to a working connected prototype.
- Hardware and software, together.
- You won't be siloed in a software team.
- You'll sit next to the mechanical and electronics engineers and work across the full system.
- Variety over repetition.
- Our projects span energy, mobility, industry, and deep tech.
- No two projects use the same tech stack.
