Job Description

🚀 Get on board with B3 — join to project that literally goes beyond Earth!

At B3 Consulting Poland, we don’t talk about rockets just for fun.

Some of the projects we work on actually power technologies used in aerospace, medical equipment, aviation and advanced electronics

As a Polish outsourcing company with Scandinavian roots, we combine Scandinavian logic, energy and experience with a work culture based on trust, ownership and long-term thinking.

Our CARE philosophy is not a slogan.

It’s how we work every day — taking responsibility, adapting solutions, and genuinely caring about people, quality and outcomes.

B3 is not just a workplace.

It’s a community of curious, engaged engineers who like to understand why, not just how 🙌
