Senior Data Engineer/ Data Architect

Why Keyrus, Why Now
Keyrus is an international group of 2,800 consultants and experts across 28 countries, built on a single conviction:

For more than 30 years, we have been building the data foundations that make intelligent systems work — designing the Operating System of the intelligent enterprise, where intelligence is embedded into the core of business processes to create sustainable value:
we operationalise intelligence.
AI does not replace humans. It repositions us to a place no system can follow:
understanding, deciding, designing, and creating.
At Keyrus, you will not just develop skills — you will develop judgment. Your expertise sharpens with every system you architect, every client challenge you solve, and every deployment that compounds on the last.
