BENEFITS OF JOINING IN GROUPE

What you’ll get (beyond the job itself)

At IN Groupe, we build secure identities and digital trust for millions of people worldwide - but we also make sure our teams feel secure, supported, and inspired every day.

Here’s what that means in practice:

Most important: employment based on an employment contract

Your health & security come first

• Private medical care (Medicover) - base package fully covered for you, with the option to include your loved ones
• Group life insurance - base package fully financed by the company
• Access to a benefits cafeteria - flexible and not limited to sports or culture

Grow your skills. Shape your path.

• Annual development budget (2000 PLN) - use it for conferences, books, or training that actually supports your work
• Access to IN Academy - our global learning platform co‑created by employees across the group
• English classes during working hours

Stay active, your way

• Multisport card (60% co‑financed) with multiple package options
• Possibility to include family members – kids, students, and seniors

Work comfortably - in a way that suits you

• Hybrid model - 2 days from the office
• Free parking
• Office stocked with coffee, fresh fruit, and snacks

A team you actually want to spend time with

• We’re a growing, 40‑person team in Poland – small enough to know each other, big enough to make an impact.
• Regular team integrations and meetups
• Monthly “Coffee Talks” - project updates, knowledge sharing, and good food
• Internal tech & topic meetups with invited speakers (you help choose the topics)

More than just work

• Ping‑pong tournaments, board game sessions, and informal hangouts
• Community team - join it and have a real influence on company initiatives, events, and workplace experience

Work that matters

• You’ll be part of a global organization with a unique legacy (Imprimerie Nationale) and a clear mission: to protect identities and secure digital interactions for millions of people worldwide.

Why it’s different here

• We combine the stability and scale of an international group with the atmosphere of a close‑knit team in Poland.
• You’re not just joining a company - you’re helping build how trust works in the digital world.
