• 5+ years of experience with datastores such as MySQL, PostgreSQL, MongoDB, or similar long-term stores.

• Strong knowledge of REST or GraphQL, RPC, and JSON.
• Working knowledge of a cloud-based environment, with a focus on AWS.
• Experience conducting and leading code reviews.
• Experience impacting a product or project in a tangible, positive manner.

• Develop custom web applications that give stakeholders an operational front-end interface to review, monitor, and execute complex business logic in a self-serve manner.
• Merge the modern data stack with software engineering capabilities, including API services, microservices, and workflow orchestration engines.
• Build automated workflows and triggers that instantly sync cross-platform systems.
• Transform static and traditional data/analytics solutions into automated operational workflows, closing the loop between data ingestion, analytical insights, and automated operational execution.
