Own delivery in an evolving product environment, including sprint planning, progress tracking, prioritization, and scope adjustments. Establish strong standards for testing, code quality, development practices, and CI/CD across a growing codebase. Lead production reliability and observability initiatives as the platform approaches and progresses through launch, including incident response and operational improvements. Establish engineering processes, norms, and practices that can support the team's growth over time. Contribute to broader engineering standards, technical practices, and hiring processes across the organization. Represent the product's engineering progress, technical risks, dependencies, and resource needs in cross-functional planning. Collaborate closely with founders, traders, and other stakeholders to ensure technical decisions remain aligned with product and business objectives.
