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 We replace outdated, manual infrastructure with fully automated systems.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

As our Senior Software Engineer, you'll be a key player in shaping Hydryx’s Landfill Management Platform. Your work will integrate IoT sensors, optimize gas extraction, and enhance predictive analytics—all in an effort to turn waste into green energy.

You will lead the development of a highly scalable, event-driven cloud platform that enables real-time data processing and intelligent automation for landfills worldwide.

Responsibilities

Architect, develop, and maintain our cloud infrastructure in AWS
Integrate and manage IoT sensor data, ensuring real-time monitoring of methane emissions and gas quality
Develop APIs for seamless integration with external energy platforms
Optimize gas extraction algorithms by leveraging machine learning and edge computing
Ensure high security, reliability, and performance in a distributed, cloud-native environment
Collaborate closely with hardware engineers to fine-tune the interaction between landfill sensors and software
Lead technical decision-making, shaping the architecture of a scalable, long-term solution
Mentor and support junior developers as we expand our engineering team

Who you are

We’re looking for someone who loves building high-impact technology, thrives in fast-paced startups, and is passionate about fighting climate change with data-driven solutions. Must-have qualifications are:

Extensive AWS experience in AWS cloud services such as EC2, RDS, Lambda, IoT Core, DynamoDB, S3, Cloudformation, etc.
Strong back-end development skills in Python, Node.js, etc.
Proficient in API development and database management (SQL & NoSQL), with a preference for experience with time series data
Experience with DevOps & security best practices for cloud infrastructure
Experience with serverless architectures, event-driven systems, and distributed computing, with a deep understanding of IoT data processing, real-time monitoring, and cloud-native applications
Implement auto-scaling strategies to handle fluctuating cloud workloads dynamically while ensuring data reliability and durability through backups, replication, and failover mechanisms
Follow best practices for version control (Git), CI/CD automation, and infrastructure as code (Terraform)

Nice-to-have qualifications are:

Knowledge of energy management systems (EMS), sustainability tech, or climate impact modeling
Experience working with sensors, environmental data analytics, or predictive modeling

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
