Meet the team!

At Preply, the Data ingestion and enrichment team provides a single, trusted, and scalable data foundation. The team ensures that all analytics, machine learning, and product features are built on unified, governed, and production-grade data assets in Preply’s Lake House, including the extraction, normalization, and generation of structured data from Preply’s unstructured assets, forming a durable data moat for AI-driven products.

What you’ll be doing

• Build trusted ingestion & enrichment foundations (Data Lake and Data as a Product): Design, build, and own Preply’s data lake. Ensure every dataset has clear ownership, purpose, schemas, and quality expectations from first ingestion through downstream consumption by analytics, product, and ML teams. Treat trust, correctness, and predictability as first-class features of the platform.
• Own end-to-end ingestion pipelines (batch & streaming): Develop and operate scalable, reliable batch and streaming ingestion pipelines that support both real-time and analytical use cases. Design clear raw → standardized → consumption layers with explicit responsibilities, lineage, and retention strategies. Balance performance, cost, and reliability as the platform scales.
• Data quality, contracts & early validation: Define and implement data contracts between producers and consumers, covering schema, freshness, volume, and quality guarantees. Embed validation, anomaly detection, and quality checks early in the ingestion lifecycle to catch issues before they propagate. Standardize how quality metrics are measured, monitored, and surfaced across the platform.
• Enrichment, modeling & lifecycle management: Build enrichment logic that joins, standardizes, and contextualizes data across domains using shared definitions and reusable patterns. Support historical tracking, point-in-time correctness, and dataset versioning so downstream users can confidently analyze changes and impacts over time.
• Observability, reliability & operational excellence: Instrument ingestion pipelines with strong observability: freshness, latency, data quality, and cost metrics. Contribute to SLOs, alerting, and incident response playbooks so data failures are visible, diagnosable, and recoverable. Help move the platform from reactive firefighting to proactive reliability management.
• Governance & compliance by design: Apply consistent access control, classification, and privacy protections at ingestion time. Ensure sensitive data is properly masked, minimized, or anonymized by default, and that all data flows are auditable and traceable. Make governance invisible to users but deeply embedded in platform workflows.
• Enable self-service & standardization: Contribute to standardized ingestion templates, shared libraries, and platform tooling that enable teams to onboard new data sources independently within clear guardrails. Improve discoverability, documentation, and metadata so datasets are easy to find, understand, and trust without relying on tribal knowledge.
• Cross-team collaboration & ownership: Work closely with Product, Backend, Analytics, and ML partners to align on ingestion requirements, trade-offs, and priorities. Promote shared ownership of data quality and platform standards, and help foster a culture where teams move fast together under common data contracts and principles.

What you need to succeed

• Exposure to and experience building architectural patterns of a large, high-scale application (e.g., well-designed APIs, high-volume data pipelines, efficient algorithms).
• Solid experience working in platform or data engineering teams (or equivalent impact) with evidence of leading multi-stakeholder deliveries.
• Familiarity with cloud platforms (AWS/GCP or equivalent) and modern DevOps practices.
• Hands-on experience designing and implementing real-time and batch data processing infrastructures using modern frameworks like Spark, Flink, Spark streaming, Kafka, Debezium, etc.
• Expertise with orchestration tools such as Airflow, dbt, or similar.
• Exceptional problem-solving skills paired with a proactive, innovative mindset focused on continuous improvement.
• Strong communication and cross-functional collaboration skills (English level B2+).

Why you’ll love it at Preply

• An open, collaborative, dynamic, and diverse culture;
• A generous monthly allowance for lessons on Preply.com, Learning & Development budget, and time off for your self-development;
• Not in Barcelona? We offer an attractive relocation package to join us in our Preply Barcelona Hub;
• A competitive financial package with equity, leave allowance, and health insurance;
• Access to free mental health support platforms;
• Access to Gympass-partnered wellness and gym centers throughout Spain to promote and support well-being and physical health;
• The opportunity to unlock the potential of learners and tutors through language learning and teaching in 175 countries (and counting!).

What we do

The open secret within the marketing and advertising industry is that it’s built on exploiting our data. Like, when you mention something to a friend and the next thing you know, you are being bombarded with adverts for it. Companies track everything we do online to follow our movement and understand our behavior. They collect this information, aggregate it, and sell it.

People have various complicated options to stop it from happening, but we believe they should have a better choice – to join the game and earn from it themselves! Monetha gives people an opportunity to be rewarded for their data. In return for sharing their data with companies, people earn points. And they can redeem these points for products, vouchers, or crypto.

In Monetha we are providing a set of solutions that enables direct communication between end-users and online services, eliminating the need to rely on 3rd party data aggregators or centralized platforms.

THE ROLE AND THE TEAM

As our Engineering Manager for the Data Enablement Team, you are a player-coach. Your mission is to lead a high-caliber team of Data Engineers in building our Centralized Data Lakehouse from the ground up. We are moving away from fragmented data silos towards a unified, high-quality Data Product architecture.

You will be the driving force behind our technical execution. While you lead the team, you aren't afraid to dive into the architecture or review complex Spark jobs. You ensure that our platform is not just a theoretical concept but a high-performance engine that delivers reliable insights. You will also ensure that we are perfectly integrated into the Zalando ecosystem, maintaining a lean and efficient exchange with their Data Foundation.

WHAT WE’D LOVE YOU TO DO (AND LOVE DOING)

• Hands-on Leadership: You lead, mentor, and hire a team of Data Engineers. You are a "maker" at heart who leads by example, promoting trunk-based development and high engineering standards.
• Platform Execution: You own the delivery of our Data Roadmap. You ensure the successful rollout of our Medallion architecture on Databricks and AWS.
• Operational Excellence: You focus on the "run" as much as the "build." You drive initiatives to optimize storage costs and implement automated data retention policies.
• Ecosystem Integration: You ensure Tradebyte’s data strategy aligns with the broader Zalando Group standards while maintaining our speed and independence.
• Data Contracts & Quality: You work with source system owners (e.g., TB.One) to ensure robust Data Contracts and end-to-end reliability from ingestion to the Gold layer.
• Technical Governance: You oversee the Unity Catalog implementation, ensuring security and governance are "built-in" features, not afterthoughts.

WE’D LOVE TO MEET YOU IF

• The "Maker" Mindset: You have a strong background in Data Engineering and have transitioned into leadership without losing your technical edge. You can still hold your own in a deep-dive technical discussion about Spark optimization or Terraform.
• Courageous Leadership: You have the confidence to challenge the status quo. If a process is inefficient or a technical direction is flawed, you speak up. You prioritize building the right solution over the easy one.
• Experience with Scale: You’ve built or managed modern Lakehouse architectures (Databricks/AWS) and know how to move from PoC to a stable production environment.
• Pragmatic Problem Solver: You prioritize results over perfect slides. You know how to balance long-term architecture with the need for quick wins (like reducing cloud spend).
• Clear Communicator: You can translate technical challenges into actionable steps for the team and provide clear updates to internal stakeholders.
• Zalando Group Context: Experience in navigating quickly a large group ecosystem is a significant plus.
