Hardware & Embedded Systems Engineer

The Role

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 working prototype. You bridge hardware and software on projects where both matter, working closely with mechanical engineers, electronics designers, and clients.

What You'll Do

• 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

What Makes This Role Different

• You'll own real products, not tickets. You'll be the firmware lead on client projects, from first firmware to 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 are the same stack.

What You Bring

Required

• Solid C/C++ for embedded systems, you're comfortable writing production firmware, not just examples

• Hands-on experience with microcontrollers (ESP32, STM32, Nordic, or similar)

• Working knowledge of digital protocols (I2C, SPI, UART, CAN) and wireless connectivity (BLE, WiFi, NB-IoT)

• Comfort in a Linux development environment, you set it up, you 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 dev environment or build tooling

• PLC programming or industrial automation experience

Mindset

• 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

Our Values in This Role

• Owning It: You're the firmware lead on your projects. When something doesn't work, you dig in. When it ships, you've earned it.

• Inventiveness: Client briefs don't come with a spec sheet for the embedded stack. You'll scope it, choose the approach, and build something that fits.

• Pioneering: We're expanding our electronics and embedded capability deliberately. This role is part of that investment. You'll help define how we do embedded engineering at Voxdale.

• Freedom and Responsibility: You decide how to structure your work, which tools to reach for, when to pair with a colleague and when to go deep solo. You also own your deliverables.
