Hydryx｜Vacancies

Who we are

At Hydryx, we’re turning landfills into climate solutions. Landfills are one of the biggest blind spots in climate tech. They leak methane, one of the most potent greenhouse gases, into the atmosphere for decades. We think that’s fixable.

‍

Founded in 2023, Hydryx builds technology that makes landfill gas systems work like they should. We replace outdated, manual infrastructure with fully automated systems. Our platform combines on-site sensors, real-time monitoring, and an AI-driven control algorithm to capture more gas, reduce emissions, and generate clean power.

‍

The entire stack is built in-house; hardware, software, cloud, and installed directly in the field. No assumptions, no black boxes. Just better control, better outcomes, and a real path to decarbonizing waste.

‍

And honestly, the fact that this sector isn’t “sexy” is exactly why it’s so interesting to us. It’s overlooked, underserved and full of low-hanging climate wins.

‍

We’re based in Amsterdam, scaling fast, and hiring. If you want to work on real-world climate problems, ones you can see, touch, and fix, come build with us.

Your role

We’re looking for a hands-on embedded engineer to own the development of our next-gen hardware. You’ll design PCBs, write firmware, and help scale our hardware to a field-proven solution.We value what you’ve built more than how many years you’ve worked. You’ve likely seen, and shipped, a wide variety of embedded systems. You will join a small, execution-focused team and work closely with our CTO and embedded (software) engineers.

Responsibilities

New MCU selection and integration
Making global connectivity work (in Brazil, Indonesia, etc.)
Making over-the-air software updates possible
Stepping away from 4G connectivity per device by designing and implementing a localized network per landfill site (e.g. mesh)
Design and test custom PCBs in order to integrate new components into our product
Optimizing for power consumption

Who you are

You’ve built multiple embedded products from scratch, we value projects over years
Strong in C/C++, low-power firmware, and real-world debugging
Experienced in schematic design, PCB layout, and prototyping
Comfortable working with IoT protocols and remote deployments
Fleet management experience
Curious, autonomous, and excited by physical product challenges

What we offer

Work that matters. You’ll build systems that capture landfill methane, turn it into energy, and cut one of the world’s biggest climate problems down to size. Real tech, deployed in the real world.
Amsterdam as home base. We’re building both a product and a team, and for that you need to be in the room part of the week. How you manage that balance is up to you, but collaboration happens fastest in person.
Upside that’s real. We offer a competitive salary, growth opportunities, and meaningful stock options - because if we win, you should share in the value created.‍
Ownership from day one. The learning curve is steep, the feedback is direct, and we’ll throw as much responsibility at you as you can handle. It’s simple: the more you raise the standard, the more trust and ownership you earn
