Internship in Electrochemical Engineering (f/m/d)

Shape the Future of Climate Tech with Phlair!

Fossil fuels have powered our economy for decades—at the cost of pollution and a changing climate. At Phlair, we’re reversing that equation. With our cost-efficient, scalable electrochemical Direct Air Capture (DAC) technology, we pull CO₂ from the air to either store it permanently or repurpose it into CO₂-negative chemicals. Join us in enabling a carbon-negative future.

Why We’re Different?

We’ve developed a breakthrough hydrolizer for acid/base regeneration, enabling scalable CO₂ capture. With partners like Frontier Climate , Stripe , and Shopify , we’re on track to make a global impact.

Our Project Dawn is our flagship initiative, setting the foundation to scale our technology and remove millions of tons of CO₂ from the atmosphere. We're one of the only seven DAC companies with a proven offtake agreement. Phlair is poised to become a technology leader, leveraging renewable energy and low-cost DAC to provide clean energy solutions that go beyond carbon removal.

Is this a fit for me?

We're building for the 3-5% who are energized by winning and thrive under pressure. Our pace demands people who see excellence as non-negotiable and execution as everything. If you need extensive structure or prefer playing it safe, we're probably not the right fit.

Your mission at Phlair

• Independently complete a suite of electrochemical characterization techniques and tests

• Process, analyze and report electrochemical data

• Refine electrochemical testing operations to ensure consistent, high-quality results.

• Contribute to an organized and clean testing area

What You Bring

• Successfully completed a bachelor or master studies in Chemistry or Chemical Engineering

• Electrochemistry or Electrochemical knowledge (water electrolysis, hydrogen fuel cells, Power2X, or redox flow batteries)

• You have experience and thrive in a lab environment

• Ability to work with us for at least 6 months

What You Bring

• Methodical & Detail-Oriented — You work carefully and focus on the details

• Reliable & Independent — You work autonomously, taking ownership of tasks ensuring completion on time.
