Embedded Systems Engineer

A farm should be full of life: cows roaming freely, soils growing richer, and farmers who can actually take a day off. We build the technology that makes that possible.

At Collie, we've built a collar and app that lets a farmer move an entire herd with a few taps on their phone. Farmers can't believe it works. Until they see it. And then they want it immediately.

We're VC-backed, growing fast, and currently selling direct to Dutch dairy farmers, going international soon. Now we're looking for a Marketing Lead who can turn that magic into momentum.

Collie is transforming dairy farming through intelligent IoT solutions. As Embedded Systems Engineer, you'll own the technical heart of their product (the smart collar) ensuring it performs reliably in real-world farm conditions while scaling to thousands of devices across multiple markets.

As Embedded Systems Engineer at Collie, you take ownership of critical embedded systems that power their innovative farm management technology. Working directly with experienced founders and hardware engineers, you design, develop, and optimize the software that enables farmers to manage their herds efficiently. Your work directly impacts product reliability, performance, and customer trust in real-world agricultural environments.

Tasks and responsibilities:

• Design and develop embedded software for Collie's hardware devices, focusing on reliability and real-world performance
• Architect and implement connectivity solutions including mesh networks and low-power communication protocols
• Optimize power efficiency and battery performance across diverse farm environments and weather conditions
• Contribute to system architecture decisions and technical strategy as the engineering team scales
• Establish test automation frameworks and validation processes to ensure product quality at scale
• Debug complex field issues and implement solutions that enhance reliability across deployed devices
• Collaborate closely with hardware engineers and founders to integrate software and hardware seamlessly

Join a flat, no-nonsense engineering culture where your contributions directly shape a tangible product used daily by farmers. You'll work in a modern Amsterdam office with experienced founders and engineers, enjoying fast iteration cycles informed by real field feedback. The organization prioritizes your growth and technical development while maintaining minimal bureaucracy and quick decision-making.

• Competitive salary between €7,000 and €9,000 monthly, depending on experience
• Unlimited holiday policy reflecting trust and flexibility
• Direct impact on a real-world product transforming agricultural practices
• Opportunity to shape technical direction as the company scales internationally
• Professional development support tailored to advancing your technical expertise
• Modern workspace in central Amsterdam with collaborative team environment
• Access to insights and best practices from a portfolio of successful deep tech companies

You demonstrate strong ownership and responsibility for your work, approaching challenges with a solution-oriented mindset. You thrive in direct, technical environments where feedback drives improvement. Your proactive nature, combined with comfort working closely with hardware engineers and founders, enables you to contribute meaningfully to both technical decisions and team culture.

Job requirements:

• Senior-level experience in embedded systems development with proven track record
• Strong programming skills in C and C++ with additional languages as advantage
• Hands-on experience with connectivity technologies such as BLE, LTE-M, LoRa, or mesh networks
• Demonstrated expertise in low-power systems design and battery optimization
• Solid knowledge of microcontrollers and embedded system architectures
• Experience debugging and testing in complex, real-world environments
• Background with IoT products deployed at scale in rugged or agricultural settings
