• Own significant portions of our internal system portfolio application end-to-end, including architecture, design, implementation, testing, and operational excellence. • Partner with the team to define and execute the long-term technical roadmap for the platform, ensuring it scales as a backbone system across multiple teams and initiatives. • Design and implement backend services in Golang and frontend components in JavaScript for a SPA architecture. • Build and maintain robust integrations with internal systems and third-party/vendor APIs, including designing resilient data ingestion, normalization, and synchronization workflows. • Improve the system’s data model, performance characteristics, and reliability as adoption and use cases expand. • Drive engineering quality: establish patterns for observability, testing strategy, CI/CD integration, and maintainability. • Identify and lead meaningful refactors, migrations, and architectural improvements as the product matures. • Conduct thorough pull request reviews and provide direct technical mentorship to engineers contributing to the system. • Leverage AI-assisted engineering tools (e.g., Claude Code or similar) to accelerate development while maintaining high standards for correctness, security, and maintainability. • Partner with Product, Security, and Platform stakeholders to ensure the application integrates cleanly with broader organizational workflows and technical systems.
