Senior Software Engineer – Full Stack (Cortex Management Team) at five9

This role is for an experienced Full Stack Developer with a strong foundation in both frontend and backend architectures. The ideal candidate has deep expertise in TypeScript/JavaScript for building modern UI (ideally with React) and is equally comfortable in the backend ecosystem, specifically with Java Spring Boot and RESTful microservices. As a senior-level position, it requires someone who can mentor junior developers and take operational ownership of the services they build. You will join the Cortex Management Team to work on the AI platform, meaning you'll be at the intersection of cloud contact center technology and cutting-edge automation. While the role is based on-site in Bengaluru, you’ll be part of a global company that emphasizes a "team-first" culture. This is a high-impact position where you aren't just writing code, but also influencing architecture and participating in the full product lifecycle, including GCP deployment and Kubernetes orchestration. **You might be a good fit if you...** * Have mastered React on the frontend and Java Spring Boot on the backend. * Are comfortable designing scalable REST APIs and working with diverse databases like SQL and Redis. * Have a track record of mentoring others and conducting high-quality code reviews. * Are eager to manage the full DevOps lifecycle, including on-call rotations and CI/CD pipelines.
