Data Engineer Porto

At Klevie, we build growth through precision, combining strategy, data, and flawless execution.

We’re not an agency. We’re not a consultancy that delivers slides and walks away.

We’re the new generation of growth consulting, and we’re looking for a Data Engineer who can turn APIs into pipelines and data into clarity.

What you’ll be doing

• Design, build, and maintain API integrations across marketing, sales, and product platforms (Google Ads, Meta, Shopify, Bol.com, and more);
• Work with REST and Graph
  QL APIs, including authentication (OAuth), pagination, and incremental data handling;
• Manage data pipelines from ingestion to storage in Google Cloud / Big
  Query;
• Write and optimize SQL queries and data models for performance and reliability;
• Ensure data quality, deduplication, and consistency across systems;
• Collaborate with strategists, performance teams, and developers to make data actionable;
• Automate workflows using Python, focusing on scalability and maintainability.

What we’re looking for

• Advanced Python skills, focused on building and maintaining API connections (not just scripting);
• Experience with Google Cloud Platform (especially Big
  Query);
• Strong SQL background and understanding of data modeling;
• Experience with REST and Graph
  QL APIs, including OAuth and pagination;
• Ability to work independently, managing projects
  -
  - end;
• Fluent in English (written and spoken).

Nice to have

• Experience with ETL tools (Fivetran, Stitch, Airbyte, etc. );
• Understanding of
  - side tagging and event tracking;
• Solid foundation in data architecture or backend development;
• Curiosity, autonomy, and the drive to figure things out.

What success looks like

• You build integrations that just work, clean, stable, and
  - documented.
• You transform fragmented data into accessible, actionable insights.
• You proactively spot inefficiencies and solve them without waiting for direction.
• You bridge the gap between technical systems and business outcomes.

What we offer

• A role in a
  - growing company redefining growth consulting;
• Exposure to international brands and
  - market projects;
• A collaborative,
  - performance culture that values autonomy and precision;
• Hybrid work model, with offices in Porto;
• Growth opportunities for those who deliver, the ceiling doesn’t exist.
