Data Engineer, Data Migration Specialist

This is a fully remote position, open to applicants in Germany.

📋 Description

• We are in the process of transitioning our entire infrastructure from self-hosted systems (Shopware 6 + Moodle) to a contemporary SaaS architecture (LearnWorlds + HubSpot).

• Your focus will not be on the shop frontend but rather on the database and cloud levels.

• We seek an individual who can execute this migration with technical precision and subsequently enhance our data infrastructure strategically.

• Data migration tasks include:

• Extracting relevant data from our mirrored Shopware database (BigQuery).

• Data cleansing (addressing duplicates, formatting, and edge cases).

• Mapping and transferring data into HubSpot’s data model (including Contacts, Deals/Orders, Products, and Line Items).

• Implementing intelligent deduplication (using email as the match key, ensuring no duplicate contacts).

• Developing import scripts through the HubSpot API (handling batch imports, rate limits, and error management).

• Conducting validation and reconciliation processes.

• Thoroughly documenting all scripts, mappings, and procedures.

• Ensuring and enhancing data quality within LearnWorlds & HubSpot.

• Building and maintaining reporting and dashboard frameworks.

• Implementing new integrations across our SaaS tools (including API connections and automations).

• Evolving our data model to accommodate new requirements.

⛳️ Requirements

• Proficiency in SQL — performing complex JOINs across relational databases is a routine task for you.

• Experience with BigQuery or similar cloud data warehouse systems.

• Familiarity with ETL processes and data migration methodologies.

• API experience (preferably with HubSpot) or the capability to quickly adapt to REST APIs.

• Scripting skills (in Python, Node.js, or equivalent languages).

• A structured and meticulous working style, including thorough documentation practices.

• Excellent proficiency in both German and English.

• Must reside in Germany.

🏝️ Benefits

• A motivated, youthful team that grows together and supports you in achieving your goals.

• Constructive, thoughtful feedback that aids in your professional and personal development.

• 100% remote work — operate from wherever you feel most at ease.

• Memorable team trips and regular events that create genuine highlights.

• An innovative workspace where you can shape solutions rather than just perform tasks.

• Trust placed in you as an individual — fostering responsibility instead of micromanagement.

• Colleagues who collaborate closely, not just work together.

• Arguably the most exciting online company in Germany — and we stand by that!
