We're building a modern data platform on AWS to consolidate data from Salesforce, monday.com | The AI work platform , and operational databases into a unified lakehouse architecture. You'll own the design, build, and operation of this platform from ingestion through BI delivery. This is a hands-on role — you'll write the code, not just draw the diagrams.

What You'll Do

• Build and maintain a medallion architecture (landing/integrated/reporting) on S3 using Apache Iceberg
• Develop and operate data pipelines using dbt-core running against Athena
• Implement ingestion patterns using AWS AppFlow, DMS, and custom Lambda functions
• Design incremental load and merge logic for CDC data streams
• Optimize query performance for BI consumption (partitioning, aggregation, file compaction)
• Build orchestration workflows using Step Functions
• Establish data quality testing, monitoring, and alerting
• Support PowerBI integration and troubleshoot refresh issues
• Document data models and maintain lineage

What You Bring

• 5+ years working with cloud data platforms (AWS strongly preferred)
• Production experience with dbt (dbt-core or dbt Cloud)
• Strong SQL skills including window functions, CTEs, and incremental/merge patterns
• Hands-on experience with at least one modern table format (Iceberg, Delta, or Hudi)
• Familiarity with Athena, Glue, or similar serverless query engines
• Experience with CDC pipelines and handling SaaS data sources
• Working knowledge of Python for custom ingestion and tooling
• Understanding of BI tool requirements and how to optimize serving layers for reporting
• Upper-Intermediate/B2 English across all four skills

Nice to Have

• Experience with Salesforce and/or monday.com | The AI work platform  data extraction
• Infrastructure-as-code (Terraform, CloudFormation)
• Cost optimization on AWS
• Data governance and cataloging practices

What You Won't Do

• Manage Spark clusters or heavy distributed compute infrastructure
• Build real-time streaming pipelines (this is batch/incremental)
• Own the BI layer — you'll support it, not build dashboards

Location: Remote (Europe / CET Time Zone preferred), with the ability to overlap with EST working hours

Type: Hourly Contractor, full-time
