• Implement complex integration patterns, ensuring our API framework remains robust and secure even when handling difficult technical scenarios.

• Develop logic-heavy features that allow our integration marketplace to scale effectively for a global partner network.

• Act as a key technical sparring partner, providing high-level feedback during code reviews and helping troubleshoot deep-seated technical issues.

• Ensure code reliability and performance through advanced testing and by maintaining a high standard for long-term system maintainability.

• Collaborate across Engineering, Product, and Design to evaluate feature feasibility and define the most efficient technical implementations.

• A disciplined approach to testing, with experience implementing patterns to ensure system reliability.

• The ability to communicate technical trade-offs clearly, providing high-level feedback to colleagues and participating effectively in technical discovery.
