Pflichtpraktikum Business Administration

Do you want to help build a climate-tech startup from the inside? If you are looking for an intership with real impact, this is for you:

At sequestra, we develop cutting-edge technology to permanently store CO₂ in industrial mineral residues and turn them into high-value, climate-friendly building materials. Our solutions sit at the core of a sector with the potential to reduce global emissions by 4 gigatons. We’re headquartered in Vienna (Millenium Tower), with two additional technical sites in Vienna (Floridsdorf) and Upper Austria (Attnang-Puchheim).

We are building the global leader in carbonation intelligence, and we’re looking for a Business Administration Intern (all genders) to work directly with our People & Operations Lead. You’ll help keep a fast-growing team running smoothly, no technical background needed. What matters is that you’re organised, curious and care about innovative sustainability.

The internship runs for 6 months, ideally from March to August 2027, but we’re flexible on start and end dates. Mandatory internships (Pflichtpraktikum) as part of a university or FH programme are very welcome.

Key responsibilities

• Take ownership of your own projects from start to finish, such as improving internal processes, building templates and documentation or organising team events. We’ll choose them together based on your interests.
• Act as deputy for the People & Operations Lead and be the go-to contact for operational questions during leave/holidays.
• Coordinate with team members, partners and service providers.
• Help create an organised, efficient and welcoming working environment for a growing team.

Skills & Qualifications

• Currently enrolled in a degree programme in business, HR, management or a related field.
• No prior professional experience required. Motivation and reliability matter most.
• Strong organisational skills and attention to detail.
• Able to work independently and take ownership, while knowing when to ask questions.
• Confident communication in English and German, both is a must.
• A real interest in sustainability and climate solutions, and ideally a healthy sense of humour.

Why join us?

• Gain hands-on insight into how a mission driven climate-tech startup is built and run.
• Get real responsibility and your own projects from day one, with close mentoring.
• Work closely with a highly motivated team in a dynamic startup environment.
• Flexible working hours, hybrid model.
• Work from our head office at Millennium Tower, Vienna.

Compensation is € 1.000 gross per month for full-time / 40 hours per week. Part time applications welcome as well.
