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
As a Working Student in Process Engineering and R&D, you sit exactly where design meets reality. You work alongside our engineering and R&D teams to develop, operate, and improve our Direct Air Capture (DAC) systems, turning concepts on paper into hardware that runs. This is hands-on work at our pilot plants in Essen, with real ownership, fast learning, and a direct line to the technology that pulls carbon from the air. If you like seeing your ideas built and tested rather than filed away, you will feel at home here.
Month 1 to 3: Learn our plants and tools, get comfortable with our P&IDs, and start supporting daily operations.
Month 4 to 6: Take ownership of CAD tasks and lead small integration jobs with guidance from the team.
Month 7 to 12: Run defined workstreams independently and propose improvements that make our setups run better.
- Help operate, maintain, and improve our DAC pilot plants and experimental setups, working hands-on at the plant.
- Build and adjust 3D CAD models and technical drawings for plant components and experimental rigs.
- Work with P&IDs to map system processes, trace lines, and document upgrades clearly.
- Support the mechanical integration of new components, such as piping, pumps, and solid-liquid separation units.
- Turn process theory into working hardware and see your contributions become part of real carbon capture systems.
- Bring fresh ideas to a team that listens, and watch the good ones make it into the plant.

About you
Must-have
- Currently enrolled in a Bachelor's or Master's in Chemical, Process, or Mechanical Engineering, or a related technical field.
- Solid foundational understanding of process engineering principles and fluid mechanics.
- Confident with CAD software such as Fusion or Inventor, and able to read and interpret P&IDs.
- A proactive team player with strong initiative and a real hands-on mentality. You like turning theory into practice.
- Available 20 hours per week and motivated to build sustainable technology.
- First hands-on experience with pumps, piping, or solid-liquid separation, from a lab, workshop, or internship.

- A small, high-trust team where your ideas shape decisions and flat hierarchies mean no micromanagement.
- Mentorship from engineers building first-of-a-kind technology, with room to learn fast.
- Direct impact on global decarbonization, with results you can see and touch.
- A supportive, curious team that takes the mission seriously and still has fun together.
- A front-row seat as we deploy our first commercial facilities over the next year.
Noteworthy points
- Location: Essen, onsite. This is a hands-on role at our pilot plants.
- Hours: 20 hours per week, with flexibility to work around your studies.
