Описание: One of the companies we work with at Joppy is looking for a Data Engineer to join the team. We're looking for an experienced data engineer with depth. You'll come from a Data Engineering background
- big data pipelines, storage systems, processing frameworks
- but what matters most is your motivation to build across layers and solve complex problems end-to-end. Data is your anchor, but this is a high-impact engineering position for someone who enjoys working with multiple parts of the system rather than in a narrow specialization. Задачи:
* Design and maintain scalable, high-throughput data pipelines and ETLs (batch and streaming)
* Architect data storage and retrieval systems using SQL and NoSQL technologies (Cassandra, graph databases) for efficient processing
* Collaborate closely with the team on system design and data modeling
* Work with cloud infrastructure on AWS and containerized environments (Kubernetes)
* Integrate and experiment with ML-based data representation techniques and emerging AI engineering tooling
* Contribute to a culture of clean, pragmatic, high-quality engineering Требования:
* Data Engineering (big data pipelines, storage systems, processing frameworks)
* Big data pipelines (Spark,



Hadoop, Kafka or equivalent)
* Python or Scala (Java welcome)
* AWS Kubernetes SQL and NoSQL databases
* DevOps practices
* 4+ years of hands‐on data engineering experience, with real depth
- you've gone deep, not wide and shallow
* Able to reason about and justify your technical decisions: pros, cons, why A over B
* Curious about how things work end-to-end, including the parts adjacent to your own
- infrastructure, backend, the systems your data feeds
* Curious about the AI ecosystem and modern developer tooling
* Comfortable in a fast-moving startup environment
* C1+ level in either English or Spanish (fluency in either is acceptable)
* Будет плюсом: Cassandra a plus; Search and graph databases (Elasticsearch, Neo4j) are a nice to have; Builders at heart: hackathons, side projects, open-source contributions, active GitHub are all highly appreciated Условия:
* Competitive salary
* Stock options
* Hybrid model: 3 days per week onsite
* New office on Gran Via (Barcelona), with a full dedicated space. Adaptable benefits covering transport, meals, and health insurance.
