We help people discover the magic of the perfect tutor, craft a personalised learning journey, and stay motivated to keep growing. Our approach is human‑led, tech‑enabled – and it’s creating real impact. We’ve just reached unicorn status with a $150M Series D, accelerating our vision to transform education through human‑led, AI‑enhanced learning. Today, 100,000+ tutors teach 90+ languages to learners in 180 countries – and we’re only getting started. As a category‑defining company, we’re shaping what the future of learning looks like at global scale. Every Preply lesson sparks change, fuels ambition, and drives progress that matters. Joining Preply means helping define the future of education at global scale, and building something that truly matters for millions of people, every day. /p h3Meet the team! /h3 pAt 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. /p h3Senior Data Engineer – Data Ingestion Enrichment /h3 pAs a Senior Data Engineer in the Data Ingestion and Enrichment team, you will design and own the data layer that powers both Preply’s analytics, machine learning, and product. You’ll work closely with ML Platform, Applied/Data Scientists, Analytics Engineering, and Product squads to ensure that features, datasets, and pipelines are production‑ready, observable, and reusable across the company. This role combines hands‑on engineering with technical leadership. /p h3What you’ll be doing: /h3 h3Build trusted ingestion enrichment foundations (Data Lake and Data as a Product) /h3 pDesign, 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. /p h3Own end‑to‑end ingestion pipelines (batch streaming) /h3 pDevelop 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. /p h3Data quality, contracts early validation /h3 pDefine 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. /p h3Enrichment, modeling lifecycle management /h3 pBuild enrichment logic that joins, standardises, and contextualises data across domains using shared definitions and reusable patterns. Support historical tracking, point‑in‑time correctness, and dataset versioning so downstream users can confidently analyse changes and impacts over time. /p h3Observability, reliability operational excellence /h3 pInstrument 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. /p h3Governance compliance by design /h3 pApply consistent access control, classification, and privacy protections at ingestion time. Ensure sensitive data is properly masked, minimised, or anonymised by default, and that all data flows are auditable and traceable. Make governance invisible to users but deeply embedded in platform workflows. /p h3Enable self‑service standardisation /h3 pContribute to standardised 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. /p h3Cross‑team collaboration ownership /h3 pWork 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. /p h3What you need to succeed: /h3 ul liExposure to and experience building architectural patterns of a large, high‑scale application (e.g., well‑designed APIs, high‑volume data pipelines, efficient algorithms). /li liSolid experience working in platform or data engineering teams (or equivalent impact) with evidence of leading multi‑stakeholder deliveries. /li liFamiliarity with cloud platforms (AWS/GCP or equivalent) and modern DevOps practices. /li liHands‑on experience designing and implementing real‑time and batch data processing infrastructures using modern frameworks like Spark, Flink, Spark Streaming, Kafka, Debezium, etc. /li liExpertise with orchestration tools such as Airflow, dbt, or similar. /li liExceptional problem‑solving skills paired with a proactive, innovative mindset focused on continuous improvement. /li liStrong communication and cross‑functional collaboration skills (English level B2+). /li /ul h3Why you’ll love it at Preply: /h3 ul liAn open, collaborative, dynamic, and diverse culture; /li liA generous monthly allowance for lessons on Preply.com, Learning Development budget, and time off for your self‑development. /li liNot in Barcelona?
