Embedded Hardware/Software Engineer

About VersaSense

Heavy industry runs on thousands of sensors. However, most of that data disappears into silos before anyone can act on it. We are building the IoT-based monitoring intelligence platform that turns sensor data into concrete operational action: emission monitoring, predictive maintenance, process insight. From the operator on the floor to the management steering on those numbers.

We run deployments in 35+ countries today, with global customers like P&G, Teck, Umicore, Unilin and Puratos. We're a small, technically strong team, and your work touches what our customers do every day.

The Role

We're looking for an embedded engineer  (payroll - full time) who lives at the boundary between hardware and firmware. This means someone who can design an IoT sensor device, lay out the board, and write the software code that runs on it. This is the layer everything else depends on: the nodes you build go into refineries, factories and stacks across 35+ countries, and are expected to run for years, untouched, on a battery.

Our domain is low-power wireless IoT: LoRa/LoRaWAN, mesh networking, battery-powered nodes that have to survive harsh industrial environments and still report reliably. Roughly a 50/50 split between board design and firmware, though the exact balance depends on whatever's on the stack. This is a high-ownership role. The hardware you design and the firmware you ship set the reliability ceiling for everything above them. A bug in the field costs a lot more than a bug in a browser.

What You'll Do

• Design IoT devices, gateways and integrate special sensors and wireless modules end-to-end: architecture, schematic design, component PCB layout, mechanical design.
• Write the embedded firmware that runs on them, incl. drivers, peripherals, communication stacks.
• Build and tune low-power wireless links (LoRa/LoRaWAN, mesh) for range, reliability and battery life.
• Integrate sensors and peripherals over SPI, I2C, UART, RS485 and related industrial protocols.
• Push power budgets hard so a node lasts years, not months
• Take designs through EMC, design-for-manufacturing, and into production
• Debug the hard problems on the bench, and when it comes to it, on a customer's site.
• You will work closely with the platform team, product, and the people who actually run the equipment.

We're Looking For

You're comfortable on both sides of the hardware/firmware line. You can read a datasheet, design the board around the chip, and write the embedded code that drives it. You care about correctness because your work ends up where a wrong reading has real consequences.

• Experience with designing embedded hardware and/or firmware, with real ownership of shipped products.
• Schematic capture and PCB design in a professional tool (Altium or KiCad)
• Strong embedded C/C++ on ARM MCUs (STM32 or comparable), and quick to pick up new stacks
• RTOS experience with Zephyr or similar systems.
• Experience or strong interest in low-power wireless technologies at depth: LoRaWAN, Mesh, BLE, antenna/RF layout, link budgets
• Solid grasp of low-level interfaces and the mixed-signal design around them (SPI, I2C, UART, ADCs)
• Hands-on with lab debugging: oscilloscope, logic analyzer, JTAG/SWD
• Practical experience with at least one wireless technology (LoRa/LoRaWAN, BLE, or similar)
• You communicate clearly, navigate ambiguity without freezing, and push back on bad ideas without making it personal

Nice to Have

• Background in industrial IoT, manufacturing, or other environments where reliability matters
• Previous startup experience
• homebrew sensing, automation, or electronics projects you built because you wanted to, not because someone paid you

How We Work

Location: Leuven, Belgium / hybrid

Languages: English as the main working language, Dutch or French are nice to have

We list a few years of experience above, however, we are open to recent graduates who can show real passion for the IoT hardware/embedded software domain.

What You Get

• Market-competitive package based on your experience and skills
• A real seat at the table on the hardware and platform's technical direction
• Autonomy, with guidance when you want or need it
• A healthy work/life balance adapted to your situation
• Room for personal growth and new skills
• Hardware that ships to the frontier of industrial monitoring, in a strong and ambitious team
