Your role

You are Hydryx's commercial engine. Not part of it, the engine itself. This is not a marketing role: it is one of the pillars this company stands on. If you succeed, Hydryx succeeds. You build our go-to-market: proposition, pipeline, playbook, and eventually the team that runs it. You work shoulder-to-shoulder with both founders, with direct lines, short loops, and a mandate most roles only promise: decide where we play, how we win, and what we build next. Treat it as your own company, because in every way that matters, it is.

Who you'll sell to

Our customers are landfill owners and operators: municipalities, public waste authorities, and large waste companies. Deals run through relationships, tenders, and formal procurement. Cycles take months, not weeks, and end in multi-year contracts. If you need a weekly win to stay motivated, this isn't your market. If you enjoy orchestrating complex, multi-stakeholder deals with real staying power, it is.

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, we've gone from idea to commercial deployments across multiple European countries, partnering with forward-thinking landfill operators who want to modernize the industry.

We replace outdated, manual infrastructure with fully automated systems.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, generate more renewable energy, and make better operational decisions based on real-time data. The entire stack is built in-house (hardware, software, cloud) and installed directly in the field. No assumptions, no black boxes.

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.

Responsibilities

• Design, build, and own Hydryx's go-to-market: from first market analysis to first customer to repeatable playbook

• Hunt and win new business: cold outreach, opening doors, pitching, closing

• Land and expand at strategic customers, growing first deals into long-term, multi-site relationships

• Iterate our proposition per region until it lands. What works in one market won't copy-paste to the next, and you treat that as a feature

• Build the commercial infrastructure: sales materials, pipeline management, forecasting and reporting, so founders and country managers always know where we stand

Who you are

• 2-5 years in B2B Enterprise sales, business development, or growth in a scale-up or founding-sales environment. You know how to built from scratch and scale, rather than just inheriting an established playbook

• A proven full-cycle closer: you've hunted, pitched, negotiated, and signed, not just managed accounts

• Comfortable in long, tender-driven sales cycles with public and industrial buyers, or eager to master them

• Persistent without being pushy, always moving conversations toward a close. "No" is data, not a setback

• Experience entering new markets or segments is a strong plus; international experience even more so

• Fluent in modern sales tooling (Claude, Attio or similar CRM, automation tools) and eager to use it

• Ambitious with patience: you want to lead a team, and you know the fastest route there is proving the engine works first

• Ever caught yourself sketching out your own startup? Good, that's what we're looking for

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

• A path to leadership. You're our first dedicated commercial hire. Once the engine runs, you hire and lead the team that scales it

• 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. If you have a good idea, test it. If it works, we'll scale it

• 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

If you're excited by building markets, closing meaningful deals, and helping solve one of the world's most overlooked climate challenges, we'd love to meet you!
