In This Role, You'll:

  • Build and maintain full stack features across our web application and data processing backend for complex telemetry data
  • Create intuitive user interfaces for data exploration while optimizing for large real-time datasets
  • Implement efficient APIs and data access patterns for real-time data streaming
  • Collaborate with data platform and frontend teams on service design and implementation
  • Write clean, maintainable code and participate in technical design discussions

The Skillset You'll Bring:

  • 8+ years of professional experience in full-stack software development
  • Experience building production applications with technologies like React, NextJS, TypeScript, Go, Rust, and Python
  • Familiarity with relational and non-relational databases, e.g. PostgreSQL, Druid, Pinot, Timescale, or similar
  • Strong problem-solving skills and attention to detail

Bonus Points:

  • Experience with technical visualization tools (WebGL, D3.js, Apache ECharts) and time-series data
  • Knowledge of WebAssembly and browser-based computation
  • Background in scientific computing or technical data visualization
