As a Principal Consultant, you're often the first person a customer meets to brainstorm a business problem. You should be at home debating distributed systems with engineers and framing decisions with leadership. You'll frame the problem with customers, shape the approach with the team, provide technical direction, and stay hands-on through delivery. You will work in self-managing, experienced, small, and high-impact teams, solving hard problems. This is a consulting & tech delivery role and while you will not have direct reports, you will regularly influence teams, mentor practitioners, manage stakeholders, and guide organisations through complex technology and business decisions.

• Redesign a ClickHouse schema so an ad buyer can query 85 billion rows in under two seconds, and discover that pre-exploding the rows 168x is actually the right answer.
• Keep a vehicle telemetry platform moving billions of messages a day without the Kafka consumers falling over.
• Build the engineering spine of a mobile wallet used by more than two billion people across four continents.
• Ship the data product behind peer-review submissions for one of the world's largest scientific publishers.

The list changes every quarter. The pattern doesn't: data-heavy, distributed, and often sitting on top of something that already exists and isn't perfect.
