• Participate in code reviews, design reviews, and technical discussions to simplify systems, reduce technical debt, and improve performance and quality across multiple services or domains.
• Own the end-to-end lifecycle of full stack features and services, including development, testing, deployment, monitoring, incident response, troubleshooting, and incremental improvement.
• Work across front-end, back-end, data, and platform domains as needed, demonstrating familiarity with AI-driven systems, tools, or workflows; applying AI/ML concepts to real-world products; and safely integrating and operating AI/ML-enabled solutions that improve outcomes.

• Solid understanding of data structures, algorithms, distributed systems concepts, and secure coding practices across client and server components.

Preferred Qualifications:

• Experience designing and implementing scalable, fault-tolerant, and high-throughput full stack solutions, including well-structured APIs, data models, and user interfaces serving multiple teams or domains.
• Demonstrated success improving front-end and back-end availability, performance, reliability, or quality through metrics, observability, automation, and strong operational practices.
• Experience integrating AI/ML-enabled components or platforms into production full stack systems, such as personalization, recommendations, intelligent assistance, or other customer-facing capabilities, with appropriate attention to safe operation.
