The Senior Software Engineer will work closely with the Staff Engineer, Product, QA, DevOps, Support, and other engineering partners. Success is measured not only by completed work, but by whether the codebase, platform, and engineering practice are stronger because of the engineer’s contribution.

Experience with distributed systems, object-oriented design, software design patterns, automated testing, and maintainable coding standards.
Experience troubleshooting production systems across application code, logs, data, infrastructure, configuration, and integrations.
Hands-on experience using AI coding assistants such as Claude Code, GitHub Copilot, OpenAI Codex, Kiro, Cline, or comparable tools.
Mature judgment regarding the value, limitations, security, quality, and responsible use of AI-assisted software development.
Experience with code reviews, source control, CI/CD pipelines, established release processes, and Agile or Scrum delivery.
