Job description

Customer Success Intern

Pillar was founded in 2025.

Today, we are 80+ people, serve 900+ customers, raised €12 million in 2026, and are expanding internationally.

We are building the operating system for construction.

Our ambition? To power one in every three construction sites in Europe.

The role

We are looking for someone at the beginning of their career who loves working with customers, solving problems and understanding why things happen.

You will join our Customer Success team and work across onboarding, customer engagement and portfolio management.

You will have real customers to follow from day one.

What you will do

• Help new customers get started with Pillar.
• Monitor customer activity and spot when something is not working.
• Proactively contact customers who are becoming less active.
• Understand why they are stuck and help them get back on track.
• Support customers throughout their journey with Pillar.
• Collect feedback and bring customer insights back to the team.
• Work closely with Customer Success and Product.

A customer hasn't logged into Pillar for five days? You notice it. You call them. You understand why. You solve it.

Who we are looking for

You don't need years of experience, we care much more about your attitude:

• You love talking to people.
• You are curious and ask good questions.
• You enjoy solving problems.
• You are not afraid to pick up the phone.
• You like convincing people and helping them find a solution.
• You are comfortable with numbers and dashboards.
• You are proactive and don't wait to be told what to do.
• You want to learn fast and work in a startup environment.

Previous experience in Customer Success, Sales or Support is a plus, not a requirement.

What we offer

• Internship contract (800 €/month)
• Real responsibility from day one
• Direct contact with customers
• Exposure to onboarding, engagement and Customer Success
• A fast learning curve
• A team where good ideas matter, regardless of seniority
• Based in Milan or Barcelona.

Hiring process

01: CV screening.

02: 30-min Talent Call - motivation, Pillar knowledge, mindset, languages, and startup fit.

03: Practical Challenge with our Customer Success Manager.

05: Final Interview with our CTO.

Fast, simple and transparent.

One last thing

We can teach you Customer Success. What we are looking for is harder to teach:

curiosity, energy, empathy and the instinct to solve problems.
