Hey there, future Data Engineer at Enlitia! Ready to revolutionize renewable energy data? Join us in challenging the status quo. As a Data Engineer, you'll sync and harmonize global wind and solar data, forming the backbone for machine learning, process optimization, and operational excellence. You'll design and develop data engineering pipelines using the best tools to ensure data availability and consistency. Collaborate with cross‑functional teams and communicate results effectively. If you're organized, motivated, and passionate about sustainability, we'd love to hear from you!

Key Responsibilities

• Data Integration & Transformation: Oversee the ingestion and harmonization of diverse data sources, ensuring reliability, consistency, and performance.
• ETL & Orchestration: Build, maintain, and optimize ETL/ELT processes with a focus on scalability, modularity, and reusability.
• Database Engineering: Design and manage high‑performance data warehouses and time‑series databases (e. g. , Timescale
  DB, Postgre
  SQL, My
  SQL).
• Quality & Governance: Implement automated data validation, quality checks, and monitoring systems to ensure integrity across the data lifecycle.
• API Integration: Develop and maintain interfaces for seamless data access and integration with internal and external systems.
• Cross‑Functional Collaboration: Partner with product, analytics, and machine learning teams to understand business needs and translate them into data solutions.
• Documentation & Knowledge Sharing: Promote best practices through comprehensive documentation and mentorship of junior engineers.

Requirements

• Hold a BSc, MSc, or Ph
  D in Computer Science, Electronic Engineering or Systems Engineering — because we like our Data Engineers powered up. ?
• 5+ years of experience in data engineering or a related field. Show us your analytical battle scars (metaphorical, of course).
• Proven experience with data pipelines design and orchestration (Prefect, Nomad, Air
  Flow…), ideally with time‑series data. Your data prowess speaks for itself. ?
• Proficiency in programming languages, mainly Python and SQL, as well as experience with OOP and Git. You're a coding ninja with these tools. ?
• Experience managing and manipulating relational databases. Knowledge about non‑relational databases is a plus.
• Strong knowledge of ETL processes and data warehousing. You're the architect of our data world.
• Excellent problem‑solving and analytical skills combined with strong communication abilities—you turn complex puzzles into compelling stories that resonate with audiences. ?
• Proven ability to work collaboratively while maintaining meticulous attention to detail, ensuring data quality and team success. ?
• Live in Portugal and speak fluent Portuguese.

Nice to have

• Experience with Go, DBT, or Bash scripting
• Previous work with ML Ops or machine learning pipelines
• Dev
  Ops Collaboration: Contribute to CI/CD processes and containerization (e. g. , Docker) to support robust and agile data delivery.
• Data Architecture: Contribute to implementation of robust data architectures and pipelines that support real‑time and batch processing of wind and solar datasets.
• Exposure to cloud platforms (e. g. , AWS, GCP, Azure) and comfort to work on‑prem.
• Understanding of big data frameworks and tools is a plus. Big data challenges are your playground.

Benefits and More

• Extra vacation days, everyone deserves some time to recharge.
• Healthcare insurance, because health is wealth.
• Meal tickets, we know debugging builds an appetite.
• Office options in Lisbon and Porto, because great work deserves a great location.
• Learning allowance, knowledge is power.
