Lead cross-team system design: Coordinate architecture across the entire purchasing journey, including discovery and search, product details, pricing, landed costs, checkout, payments, and post-purchase experiences.
-
Establish clear service boundaries: Define robust API contracts and Backend-for-Frontend (BFF) patterns that support iOS, Android, and web applications.
-
Build scalable backend services: Design, develop, test, and maintain reliable Go services while remaining hands-on with complex technical challenges and critical implementation work.
-
Enable global platform scalability: Develop systems that support multiple regions through a consistent global platform, avoiding unnecessary country-specific fragmentation.
-
Own production reliability: Establish standards for observability, safe deployments, incident response, and continuous operational improvement across marketplace services, partner integrations, payment systems, and third-party providers.
-
Accelerate engineering delivery: Help two to four engineering teams overcome complex design challenges, simplify platform architecture, and improve delivery speed and quality.
-
Advance AI-assisted engineering: Integrate coding agents, AI-assisted code reviews, automated testing, debugging, and operational automation into the software development lifecycle.
-
Drive cross-functional alignment: Collaborate with product managers and engineers across India and Japan to turn ambiguous business and technical challenges into actionable engineering plans.
-
Mentor technical leaders: Coach senior engineers, strengthen architectural decision-making, and help engineering teams use AI agents effectively while maintaining high standards of software quality and reliability.
