  • Build and manage data access layers, including REST APIs and streaming services, to empower downstream users
  • Drive data governance and best practices: Contribute across teams to recommend tools, processes, and best practices for maintaining data health, integrity, and security
  • Support AI operations (MLOps) by managing versioning, containerization, and deployment of AI models
  • Build monitoring and alerting systems to track data health and system performance, proactively identifying and remediating bottlenecks

  • You understand modularity and how to define clear scopes and responsibilities within a large codebase
  • Proven experience architecting scalable relational and non-relational (SQL/noSQL) schemas 
  • You manage the end-to-end database lifecycle, from initial design to production maintenance
  • Expertise in maximizing system performance through advanced query tuning, strategic indexing, and execution plan analysis to eliminate technical bottlenecks
  • Experience with one or more cloud-based databases (e.g., AWS RDS, Azure Database)
  • You are comfortable configuring compute resources, backups, and geolocation requirements
  • Experience building resilient pipelines using frameworks such as Dagster or Apache Airflow 
  • You have a track record of maintaining data health for both real-time streaming and batch processing
  • A strong understanding of how data infrastructure integrates into the broader application architecture
  • Experience with modern software development practices, including version control (Git), CI/CD pipelines, and a commitment to high-quality, maintainable code
Preferred Qualifications:
  • Experience working with streaming data (e.g., Kafka) or running data models on the edge (e.g., Raspberry Pi, IoT devices)
  • Familiarity with containerization and orchestration tools such as Docker and Kubernetes
  • Experience architecting and consuming scalable RESTful APIs using standardized design principles and robust authentication protocols
  • Familiarity with blockchain data indexing or privacy-preserving data processing techniques
  • Experience mentoring junior engineers or leading technical projects within a high-performing team
