• External Integration: Collaborate directly with external partners and customers on technical integrations and iterative feature development.
• Quality & Standards: Uphold high standards for clean code, automated testing, and comprehensive API documentation.
• System Ownership: Manage the entire lifecycle of a feature, from the initial prototype through launch, monitoring, and future iterations.

1. Hiring Manager Interview: An initial discussion with the Head of Engineering to review background, technical skillset, and alignment with the organization’s engineering culture.
