Senior Data Engineer – all genders

Role Overview

• You will set the architecture, the standards, and the roadmap for our Databricks lakehouse, and raise the bar for everyone working on data at MICE DESK.
• Own the design of our lakehouse (Medallion architecture on Databricks): tenancy model, storage layout, orchestration, streaming vs. batch strategy, cost management, and the evolution path as customer volume grows 10x.
• Design the ingestion framework that makes onboarding a new hotel group a configuration task, not an engineering project — across wildly heterogeneous PMS/CRM sources and both EU and US data residency requirements.
• Build the interfaces between the data platform and its consumers: feature pipelines for our ML models, low-latency serving for in-product analytics, and the contracts that keep both stable.
• Define engineering standards for the data team — testing, CI/CD for pipelines, documentation, data contracts — and mentor data engineers toward them.

Requirements

• 5+ years in data engineering, including architecture ownership of a production data platform
• Deep, hands-on Databricks and Spark expertise
• Proven design of multi-tenant or large-scale data systems
• Strong software engineering practice: testing, CI/CD, infrastructure-as-code for data
• Experience mentoring engineers or leading data workstreams
• Strong English (B2–C1), German (B2)
• Nice to have, not required: Lakehouse/Medallion architecture at scale
• Streaming architectures (Kafka, Delta Live Tables, structured streaming)
• ML platform / feature store experience
• EU data residency / GDPR-aware architecture experience
• B2B SaaS background.

Tech Stack

• Kafka
• Spark

• A short path to the management team.
• Decisions take days, not committee rounds.

• We are building the company’s next chapter — with roles, responsibility and prospects that did not exist a year ago.
• Leipzig as your primary base, with regular time in the office and flexible remote work.
• Hybrid models are everyday practice here, not the exception.
• Permanent contract, full-time.
• Performance bonuses for demonstrable results.
• Multi-day team events in places that are actually fun.
