Job description
Overview
We are looking for 3 contingent workers who can understand and write database queries, have average coding proficiency, and are familiar with APIs.
Qualifications
- SQL (Read + Write) — Ability to understand, write, and troubleshoot database queries. Must be comfortable reading existing queries with JOINs, GROUP BYs, WHERE filters, and aggregate functions. Writing new queries from requirements.
- API Familiarity — Experience consuming REST or GraphQL APIs. Understanding of request/response patterns, authentication, error handling, and how to read API documentation to build integrations.
- Full-Stack Web Development (Basic) — Comfort working in a TypeScript/React codebase. Ability to read, modify, and extend existing components and data-fetching hooks. No senior-level architecture skills required — following established patterns is sufficient.
- Familiarity with Next.js or similar React frameworks
- Exposure to data validation / QA practices (comparing query results across systems)
- Basic understanding of data pipelines or ETL concepts
- Write and optimize SQL queries pulling data from multiple internal data sources (ticket systems, metrics platforms, server health databases)
- Integrate GraphQL API endpoints into the dashboard application
- Validate that query outputs match source-of-truth systems — document discrepancies and fix filter logic
- Extend existing React/TypeScript components to surface new data points
- Document data source filters, refresh cadences, and known limitations
- Support cross-source data reconciliation (understanding why numbers from different systems may not match exactly)
