Our hiring process is designed to be as welcoming and efficient as possible for all candidates. It begins with a brief prescreening to verify your basic qualifications and experience in business analysis and insurance. If your profile matches our needs, we will invite you to participate in two interview rounds:

• First interview round: This stage focuses on a deeper understanding of your technical skills, experience with insurance software, and your ability to solve complex business challenges. You will have the opportunity to showcase your previous projects and discuss your working methodologies.

• Second interview round: The final phase involves meeting with our team, where we will assess your communication skills and ability to collaborate in an international environment. We may also include case studies or practical tasks to evaluate your skills in real-world scenarios.

We believe this approach allows us to find the best candidate who is passionate about our vision and values. We look forward to your participation and the opportunity to get to know you better!

Whitestein Technologies was founded in 1999 in Switzerland with a single conviction: that the financial institutions of Europe deserve software built around the way their business actually works — engineered for the long run, adaptive to change, transparent under audit.

Our first banking project shipped in 1997; our first insurance project in 2000. In the years since, we have built and modernised core platforms for Generali, Zurich, VIG, Axis Re, Swisscom, and several of Europe's largest banks — and stayed on as the engineering team behind those systems for ten, fifteen, twenty years and counting.

Today the company combines two strengths: a Swiss head office where strategy and contracting sit, and a 50-engineer delivery centre in central Bratislava where architects, engineers, business analysts, and QA specialists work alongside our clients in CET hours. Many of those relationships have run for 10–20 years, and many of the platforms we built are still in continuous production more than a decade after we first shipped them.
