Preferred Qualifications: · Experience designing and evolving service architectures, including thoughtful low-level design, API contracts, and data models that support reliability, performance, and extensibility. · Proven experience operating systems at scale, including monitoring, alerting, incident response, and continuous improvement of reliability, latency, and cost. · Track record of using data and experimentation to drive engineering decisions, optimize user experiences, and improve system behavior. · Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products, including safely integrating AI/ML‑enabled capabilities into existing services. · Experience contributing to technical direction within a team through code and design feedback, and applying modern engineering practices (e.g., automation, security-by-design, performance tuning) to elevate overall code quality.
