Job description

Ready to scale your career in a high-growth scale up where your results drive real world change?

We’re Sensorfact , Europe’s #1 smart monitoring platform for the industry , on a mission to make industry smarter, cleaner, and more efficient. Every day, our technology helps thousands of manufacturers cut energy waste, reduce costs, and lower carbon emissions through intelligent data insights and automation.

Today, we’ve joined forces with ABB, a global leader in electrification and automation. This partnership has propelled us onto the world stage, enabling us to expand rapidly and help more businesses optimize their energy efficiency, cut costs, and make a positive impact on the planet.

What you will do:

You will eliminate industrial waste by architecting the next generation of IoT solutions that bridge the gap between hardware and the cloud. As a primary enabler in this hardware enabled SaaS mission, you lead the end to end development of wireless sensor systems from initial research and customer pilots to managing a massive scalable fleet. You will work within cross functional teams to master embedded software and automated factory feedback while ensuring data science teams have the high quality insights needed to drive global efficiency. Beyond technical execution, you provide the engineering leadership necessary to mentor peers through design reviews and scale a greener industrial future.

Some of the things you will be doing in your day-to-day work will be:

• Develop and maintain our embedded software on the gateway devices and sensors.

• Design, develop, and maintain our tools for fulfillment and onboarding, always striving to make them better but also more efficient.

• Researching, prototyping, conceptualizing, optimizing and productizing new sensor solutions based on product requirements.

• Collaborate with cross-functional teams to define and architect end-to-end IoT solutions that meet product goals and technical requirements.

• Code reviews and provide feedback on your colleague’s work.

• Participate in brainstorming and ideation sessions to solve scalability challenges like, for example, different radiofrequency regulations worldwide or how to maintain and manage a diverse fleet of IoT devices.

What you bring:

Must have:

• 3+ years of experience building software for (connected) devices, preferably with (industrial) IoT products based on embedded Linux.

• You have worked with a variety of interfaces such as serial ports, I2C, and modbus.

• You have experience with data acquisition and working with different sensor types.

• Knowledgeable about or willing to learn about our tech stack: MQTT, NATS, Debian, Fleet management (OTA), mTLS, and monitoring.

• Knowledgeable of low-level Linux such as boot sequence (u-boot), bash scripting, systemd, and networking.

• You are comfortable in a growing, changing environment; even more than that, you thrive in these. We are a product-driven company, so customer impact is what guides us, engineering sustainability and excellence is what fuels us.

• You like an effective and clear communication style and work well with colleagues from different backgrounds and expertise.

Nice to have:

• Have an MSc level education, preferably in a technical field, preferably specializing in embedded systems, industrial technology, or similar.

• You have knowledge or experience with wireless protocols e.g: EnOcean, BLE, LoRa, WiFi, LTE

• You are familiar with electronics design.

• Demonstrable working experience with IoT communication protocols

• Previous experience in IoT system architecture and design

Why you will love working here:

• Grow your career as we scale

• Pension Contribution of 4% with an employer sponsored retirement plan

• Public transport allowance via NS business card

• Employee Referral Incentives up to €3,000 for a successful referral
