Senior Data Engineer — Financial Services — Contract (Remote, Brazil)
Santiago Consult is a UK-based data and AI consultancy. We build data platforms, pipelines and AI systems for clients across the UK and Europe, and we're expanding our delivery capability in Brazil.
We're building a network of senior contract data engineers with financial services experience, ready to bring onto client projects as they start. This is a talent pool ahead of upcoming engagements, so we want to talk to strong people now even if a project isn't live on day one.

Production data engineering experience in financial services, banking, fintech, payments or insuranceStrong SQL — performance tuning, window functions, complex transformationsStrong Python for data engineeringSolid production experience with BigQuery or Snowflakedbt in a real production environmentGit and a proper branching/review workflowExperience with data that has to reconcile, and where mistakes have consequencesComfortable working in English with UK-based clientsCloud platform experience — GCP or AWS
