• Define and drive technical standards, architecture decisions, and engineering best practices across multiple teams.
• Serve as a technical leader and mentor, elevating engineering capabilities through design reviews, technical guidance, and knowledge sharing.
• Remain hands-on by contributing production-grade code for business-critical systems and services.
• Collaborate closely with Product, Design, Compliance, and Engineering stakeholders to translate business objectives into scalable technical solutions.
• Drive modernization initiatives, including migration from legacy platforms to modern architectures and cloud-native solutions.
• Champion the adoption of AI-powered development tools and establish best practices for integrating AI throughout the software development lifecycle.
• Contribute to system architecture, platform scalability, performance optimization, and operational excellence.

• Deep expertise in software architecture, system design, microservices, service-oriented architecture, and event-driven systems.
• Demonstrated experience leading complex, cross-functional technical initiatives as an individual contributor.
• Proven ability to mentor and develop engineers through technical leadership rather than direct people management.
• Extensive hands-on experience using AI-assisted development tools such as GitHub Copilot, Cursor, Claude Code, or similar platforms.
• Strong experience with AWS cloud services and modern deployment practices, including CI/CD pipelines and services such as SQS, DynamoDB, S3, ECS, and Lambda.
