Who we are
At Hydryx were 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 thats 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 We replace outdated manual infrastructure with fully automated systems.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 isnt sexy is exactly why its so interesting to us. Its overlooked underserved and full of low-hanging climate wins.
Were 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
You are addicted to solving puzzles. You love staring at graphs analysing live data streams and questioning every decision the system makes. Youre obsessed with our front-end; constantly checking valve positions and gas readings. Is our algorithm working as it should Why did we make this decision Can we do better
Your work builds Hydryxs core USP and IP the intelligence that makes landfills behave like renewable energy plants. Its exactly as important as it sounds.
The models you deploy will have an instantaneous real-world impact on reducing emissions and optimizing renewable energy generation
Responsibilities
Own the Hydryx control algorithm from model design to live deployment
Analyse real-time landfill data and continuously improve model accuracy
Build test and refine forecasting algorithms for gas composition and well interactions
Integrate external data (weather pressure temperature) to enhance predictions
Collaborate closely with the Operations team to turn field insights into control logic
Design A/B experiments to test control strategies and quantify performance improvements
Work with the CTO and embedded engineers to bring models to life in the field
Who you are
Proven track record building forecasting or control algorithms
Experience with time-series modeling ML and AI forecasting
Background in energy systems process control or environmental data preferred
Advanced proficiency in Python
Skilled in API development with a strong understanding of REST API principles
Understanding of core AWS cloud services (RDS EC2 Lambda Sagemaker)
Experience with cloud deployment (Containerisation CICD pipelines Infrastructure as Code etc.) and MLOps practices
Strong communication skills and comfortable collaborating across hardware data software and operations teams
Show us the hardest problem you worked on.
What we offer
Work that matters. Youll build systems that capture landfill methane turn it into energy and cut one of the worlds biggest climate problems down to size. Real tech deployed in the real world
Amsterdam as home base. Were 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 thats 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 well throw as much responsibility at you as you can handle. Its simple: the more you raise the standard the more trust and ownership you earn
Good times included. From free daily healthy lunches and Friday beers to team dinners and a ski trip in February we work hard but we also make time to celebrate the ride together
Landfills are responsible for 6% of global emissions. Yet we believe that under every landfill lies a powerful opportunity and that great landfill management is a key part of the circular economy. We started Hydryx to prove that with the right technology we dont have to choose between ... View more
