• Collaborate with product, operations, customer-facing teams, and external technical contacts to turn integration requirements into maintainable technical solutions.
• Investigate production issues across application code, integrations, rules, and data; identify root causes and deliver durable fixes.
• Contribute to technical design, code reviews, automated testing, and API/integration documentation.
• Use AI-assisted development tools, such as Codex and Claude, thoughtfully to improve development speed, investigation, documentation, and code quality.
