Senior Data Engineer

🎯 What You’ll Actually Do

• Design and run high-throughput, production-grade data pipelines.

• Own data correctness, latency, and availability end to end.

• Make hard trade-offs: accuracy vs speed, cost vs freshness, rebuild vs patch.

• Design for change — schema evolution, reprocessing, and new consumers.

• Protect BI, Product, and Ops from breaking changes and silent data issues.

• Build monitoring, alerts, and data quality checks that catch problems early.

• Work side-by-side with Product, BI, and Engineering — no handoffs, shared ownership.

• Step into incidents, own RCA, and make sure the same class of failure never repeats.

This is a hands-on senior IC role with real accountability.

🧠 What “Senior” Means Here

You:

• Think in systems, not tools.

• Reason about failure modes, not happy paths.

• Can explain why a solution works — and when it breaks.

• Take responsibility for outcomes, not just implementation.

• Stay effective with incomplete, evolving requirements.

🧠 What You Bring (Non-Negotiable)

• 5+ years in data or backend engineering on real production systems.

• Strong experience with analytical databases
  (ClickHouse, Snowflake, BigQuery, or similar).

• Experience with event-driven or streaming systems
  (Kafka, CDC, pub/sub).

• Solid understanding of:

  • at-least-once vs exactly-once semantics

  • schema evolution & backfills

  • mutation and reprocessing costs

• Strong SQL and at least one programming language
  (Python, Java, Scala, etc.).

• You don’t just ship — you own what happens after.

🔥 What Sets You Apart

• You’ve seen data systems fail in production — and fixed them.

• You think about cost when making architectural decisions.

• You understand data contracts and change management.

• You can translate technical choices into business impact.

• You’re comfortable saying: “I don’t know — here’s how I’ll figure it out.”

🚫 This Role Is NOT

• Not a dashboard-only BI role.

• Not a ticket-driven ETL executor.

• Not a pure infrastructure or DevOps position.

🔧 How We Work

• Reliability > cleverness.

• Ownership > process.

• Impact > output.

• Direct > polite.

• One team, one system.

🔥 What We Offer

• Fully remote (Europe).

• Unlimited vacation + paid sick leave.

• Quarterly performance bonuses.

• Medical insurance for you and your partner.

• Learning budget (courses, conferences, certifications).

• High trust, high autonomy.

• No bureaucracy. Real data problems.

👉 Apply if you treat data like production software — and feel uncomfortable when numbers can’t be trusted.
