Data Engineer

About the role

About LANCH
LANCH, the fastest-growing consumer company in DACH, is seeking a talented and motivated Data Engineer to join our dynamic team.
Founded in 2023 and headquartered in Berlin, LANCH partners with restaurants and top creators to launch delivery-first food brands such as Happy Slice pizza, Loco Chicken, and the new Korean-style Koco Chicken. Beyond virtual kitchens, we are rolling out a network of physical restaurants and retail brands (“Happy Chips”, “Loco Tortillas”) that already reach thousands of supermarkets. Backed by €26 million in Series A funding (Feb 2025), our Tech & Data team is building the platforms - LANCH OS and the Partner Portal - that power everything from menu management to supply-chain automation.

The Role
We’re looking for our first Data Engineer to lay the foundations of LANCH’s end-to-end data platform. You’ll own everything that turns operational events into trusted, analysis-ready datasets - from real-time streaming and batch pipelines to the orchestration frameworks that keep them humming. Working hand-in-hand with product, engineering, and ops, you will design and implement the data infrastructure that powers menu optimisation, delivery routing, brand performance dashboards, and much more.

Key Responsibilities

• Architect and launch a scalable event-streaming platform (e.g., Pub/Sub, Kafka) that captures orders, logistics updates, and app interactions in real time.
• Build and maintain a modern Reverse ETL layer (e.g., Census, Hightouch) to push clean warehouse data back to internal applications like our Partner Portal, LANCH OS, or our CRM.
• Evolve our Airflow and ELT environment: modular DAG design, automated testing, CI/CD, observability, and cost-efficient GCP execution.
• Collaborate with backend engineers to instrument services for analytics & tracing; champion event naming conventions and schema governance.
• Set engineering standards - code reviews, documentation, security, and infra as code (Terraform) - that will scale as we 10x the team and data volume.

About you

About You – what will make you thrive at LANCH

• 2+ years building data infrastructure in cloud environments.
• Professional experience in designing and developing ELT pipelines.
• Hands-on experience with at least one streaming technology (Pub/Sub, Kafka, Kinesis, Dataflow, ...).
• Fluent in Python for data processing; comfortable writing performant SQL (BigQuery dialect a plus).
• Proven track record orchestrating pipelines with Airflow (or Dagster, Prefect) and deploying via Docker & GitHub Actions.
• Product mindset: you enjoy sitting with ops teams or restaurant managers to translate fuzzy business challenges into robust data pipelines.
• Bias for action and ownership: you prototype quickly, measure impact, and iterate - yesterday’s idea should be today’s scheduled DAG.
• Collaborative communicator - fluent English; conversational German.
• Eager to work mostly on-site in our Berlin Prenzlauer Berg office.
