The Senior Data Developer will own the relational and lakehouse data behind a higher-education platform's program, student and enrollment data. That data has to be correct, fast and well governed, so that analytics, CRM and partner-facing applications can trust it. Success depends on taking ambiguous data problems from analysis to production on your own, making sound performance and modeling trade-offs, and keeping a high quality bar across the team.\nResponsibilities:\nDatabase Development: Design, build and tune schemas, stored procedures, views, functions and indexes. Lead query-plan analysis and performance work.\nLakehouse Engineering: Build and maintain Databricks pipelines (PySpark / Spark SQL) and dbt models using Kimball dimensional modeling.\nDual-Layer Delivery: Support both the transactional SQL databases used by applications and the lakehouse models used for analytics.\nData Governance & Quality: Manage data access and lineage in Unity Catalog. Implement quality checks and source-to-target reconciliation, and protect sensitive personal data (masking, row-level access).\nEngineering Practices: Version database changes in Git, deploy through CI/CD, and review peers' SQL.\nKnowledge 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.\nCollaboration: Work with the Data Architect on modeling standards, and with application developers on API and data contracts.\nMentorship: Mentor mid-level developers and explain technical trade-offs to client architects.\nNearshore Delivery: Work with North American stakeholders and teams in Brazil and Colombia, keeping strong overlap with US business hours.\nRequirements:\nAdvanced/fluent English (C1 or above)\nExpert SQL (T-SQL and/or ANSI), including stored procedures, window functions, CTEs, indexing and execution plans\nSolid experience with relational databases (SQL Server / Azure SQL preferred, or PostgreSQL or similar)\nHands-on production experience with Databricks, PySpark, Delta Lake and dbt\nSolid experience with dimensional modeling (Kimball) and data warehouse design\nExperience with Git, CI/CD for database changes and Jira\nNice to have:\nUnity Catalog administration\nDatabricks certification (Data Engineer Associate / Professional)\nExperience with orchestration and ingestion tools (Databricks Workflows, Airflow, ADF, Fivetran)\nExperience with data quality frameworks (Great Expectations, dbt tests)\nExposure to BI tools (Power BI or Tableau)\nExperience with regulated data (education, healthcare or privacy regulations such as LGPD)\nFamiliarity with AI-assisted development and agentic coding","description_format":"text","description_chars":2821,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Brazil","iso":"BR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Outsourcing & Dedicated Teams","Custom Software Development","AI Consulting & Integration","Data Engineering & Migration Services"],"lifecycle":[{"event":"open","at":"2026-10-02T18:58:45Z"}],"visa":[],"liveness":{"score":70,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.695,"p_room":1,"age_days":1,"expected_fill_days":18,"reasons":["conf:0","stale_co","wave","velocity","win:early","comp:brand"],"computed_at":"2026-10-04T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/cit-senior-data-developer-brazil-4","json_url":"https://alion.io/job/cit-senior-data-developer-brazil-4.json","meta":{"generated_at":"2026-10-05T03:10:02Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4322,"day_limit":5000,"remaining_today":678,"minute_limit":60,"resets_at":"2026-10-06T00:00:00Z"}}}
