Sr Staff Software Engineer - AI | Studio at five9

This role is designed for a seasoned technical leader with at least 12 years of experience building large-scale, distributed SaaS applications. You should be a master of the Java/Spring Boot ecosystem and comfortable navigating cloud-native architectures (AWS, GCP, or Azure). As a Senior Staff Engineer, you will balance high-level architectural strategy with hands-on coding, specifically focusing on integrating Generative AI and LLMs into cloud contact center solutions.

This is a high-impact position where you aren’t just building features—you are reimagining customer experience through AI agents and microservices. The role offers the opportunity to lead deep technical root-cause analyses and mentor local teams while pushing the boundaries of AI-driven development. **You might be a good fit if you...** * Have 12+ years of experience in backend microservices and distributed systems. * Are an expert in Java, Python, and Kubernetes with a solid grasp of SQL/NoSQL databases. * Want to lead the practical application of GenAI and LLMs within an enterprise microservices platform. * Enjoy being the "go-to" technical expert for complex, high-impact production challenges.
