Experienced Embedded Engineer

About Hydryx

At Hydryx, we're turning landfill emissions into clean energy. Landfill methane has more climate impact than global aviation and shipping combined. We're building the hardware and software to change that, automating gas extraction for more green energy and less emissions. Simple. Scalable. Deployable today.

We’re scaling fast and looking for builders who want to solve real-world problems, up close, in the field, and as part of a tight, technical team.

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 software engineers. 

What you will work on

• Design and test custom PCBs with gas sensors, actuators, and wireless modules
• Write robust embedded firmware (C++) for low-power, remote systems
• Build and optimize wireless connectivity (e.g. LTE, LoRa, NB-IoT)
• Integrate hardware into our cloud software stack
• Test, deploy, and improve the product through field feedback

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
• IoT device fleet management (with firmware focus)
• Curious, autonomous, and excited by physical product challenges

What We Offer

• Freedom to build real, working hardware with massive climate impact
• A key role in a team where ownership is real
• A fast-paced, no-nonsense environment where you can go deep technically
• Competitive salary + equity
• An office and workshop in Amsterdam where ideas sharpen fast (we’re not remote-first)

Logistics

• Start date: ASAP
• Location: Amsterdam / Hybrid
• Position: Full-time (32 - 40 hours per week)

How to Apply

Let’s build climate tech that works, literally.
