  • Contribute to design and troubleshooting discussions to gather voice-of-customer feedback
  • Create and maintain development documentation to preserve knowledge across the product lifecycle
  • Take ownership of communication including consistent follow-up with internal and external customers

Skills Required:

  • Experience with JavaScript in production environments is required
  • Strong debugging expertise, with proven ability to isolate failures across code, libraries, and dependencies
  • Superb and timely written and verbal communication with technical and non-technical stakeholders
  • Experience with Microsoft Office and collaboration tools, including Teams
  • Demonstrated ability to create clarity through standard work and documentation
  • Agility to move from feature engineering to field support without losing quality
  • Commitment to repeatable execution across build, test, and release processes
  • Experience with Agile (Plan, Sprint, Review), formal problem solving, and continuous improvement is a plus
  • Experience using modern AI-assisted tools for debugging, documentation, and test acceleration is a plus
  • Experience with cloud integrations including Amazon Web Services and client-to-cloud data flows is a plus
  • Experience with Elixir and/or React programming or troubleshooting is a plus

Qualification Requirements:

  • Bachelor's degree in CS/SE/CE/EE (or related field) preferred
