About the role

Senior Data Developer responsible for owning the relational and lakehouse data behind a higher-education platform’s program, student and enrollment data, with emphasis on correctness, performance, governance and production-readiness across analytics, CRM and partner-facing applications.

Responsibilities

  • Database Development: Design, build and tune schemas, stored procedures, views, functions and indexes. Lead query-plan analysis and performance work.

  • Engineering Practices: Version database changes in Git, deploy through CI/CD, and review peers' SQL.
  • Knowledge Transfer & Operations: Take over existing schemas and jobs from previous teams without disrupting production. Document data models and runbooks, and support incident resolution and root-cause analysis.
  • Collaboration: Work with the Data Architect on modeling standards, and with application developers on API and data contracts.
  • Mentorship: Mentor mid-level developers and explain technical trade-offs to client architects.
  • Nearshore Delivery: Work with North American stakeholders and teams in Brazil and Colombia, keeping strong overlap with US business hours.
