Job Description

Let’s build the fossil-free future

At Greenlyte, we are reshaping the global fuel economy with our novel, IP-protected, direct air capture to fuels technology, which shows superior economic potential compared to existing approaches, even reaching fossil prices. Backed by leading European VCs and with commercial agreement from Lufthansa and MB Energy, we are deploying our first commercial facilities to prove commercial viability in the next 12 months.

Where Ambition Meets Purpose
We are not waiting for change. We are building it together. At Greenlyte, speed and collaboration define how we work. Our culture rewards initiative, learning, and teamwork. If you want to grow fast, take ownership, and shape real impact, this is the place to do it.

How you'll contribute

This is an early-career role with real ownership. You will work at the core of our first commercial plant deployment, designing, specifying, and coordinating the technical backbone that makes it happen. You will have experienced engineers around you to challenge ideas with and learn from. We do not micromanage. We give you clear goals, a strong team, and expect you to grow into your own way of solving problems. Growth here is fast because the problems are real and the stakes are high.

• Own and maintain core engineering documents, P&IDs, BFDs, and equipment specs, driving them through revisions and keeping them accurate as the project evolves.
• Design for flexibility, accept that information arrives in stages, structure your work to absorb that, and communicate uncertainty clearly and early.
• Act as the technical liaison to our suppliers: evaluate equipment options together with the supply chain team and stay the go-to contact from selection through delivery.
• Work out and challenge mass and energy balances; perform your own calculations for heat loss, pressure drops, and structural estimations.
• Develop scalable factory standards for future projects, including pipe classes, modular concepts, and reusable design principles that outlast this deployment.
• Navigate ambiguity with support: assess whether a problem is relevant, identify where to find answers, and help design tests when no one else has them yet.
• Build cost awareness from day one: understand what drives costs and flag them early in the design process.
• Collaborate across functions, working directly with Systems Engineering and Operations, in a flat structure where everyone is approachable and willing to help.

Your first 12 months in the role

Week 1 to 4
Onboard into the team and the FOAK project. Get up to speed on existing P&IDs, BFDs, and equipment specs. Map the document landscape and understand what needs updating and why.

Month 1 to 3
Own your first set of documents end to end. Drive revisions, manage release cycles, and keep specs aligned as design decisions evolve. Make your first independent equipment calls together with the supply chain team and establish working relationships with key suppliers.

Month 4 to 6
Run your own process calculations without being asked. Challenge the M+E balance where numbers don't feel right. Start contributing to factory standards: pipe classes, modular concepts, reusable design principles. Flag cost drivers early and make them visible to the team.

Month 7 to 12
Be the person who knows the documents, the suppliers, and the open questions better than anyone else in your scope. Contribute to scalable standards that will outlast this project. Communicate uncertainty clearly, keep parallel workstreams moving, and be a reliable technical voice in cross-functional discussions.

About you

Must-have

• Degree in process engineering, chemical engineering, mechanical engineering, or a closely related field.
• Solid understanding of thermodynamics, fluid mechanics, and basic process calculations; you can work through an energy and mass balance and know when to ask for a second opinion.
• Experience reading and working with P&ID drawings; you do not need to be a Smap3D expert, but you know your way around a diagram.
• Comfort with open questions: you can identify what you do not know, figure out how to find it, and keep moving without waiting to be told.
• Clear, direct communicator; in a flat team, good ideas come from everywhere and yours are welcome.

Nice-to-have

• Experience with Autodesk tools (Fusion, Inventor) for 3D modelling or plant layout work.
• First exposure to international project environments or supplier management.
• Any hands-on experience with plant or lab equipment; even during studies counts.

What we offer

• 30 days of vacation; rest is part of performing well.
• Real ownership from day one; your work ships to a real plant, not a drawer.
• A small, high-trust team where decisions get made fast and your perspective shapes them.
• Regular team events and an office culture built on curiosity and good vibes.

Noteworthy points

This role is based onsite in Essen. Project work is international in scope; you should be comfortable working with suppliers and partners in different geographies and adapting to changing environments. Did you like what you just read?
