Sr Software Engineer - Backend Engineer | IND at five9

This role is designed for a seasoned Full-Stack professional with at least 7 years of experience who bridges the gap between robust backend architecture and modern frontend interfaces. While the title emphasizes Backend, the requirements call for a versatile engineer who is equally comfortable writing C# in .NET Core as they are building UI components in React.js and TypeScript. This is a key hire for the expanding Bengaluru engineering hub, offering the chance to work on high-scale, cloud-native microservices within a global enterprise environment. The position is ideal for those who enjoy the technical challenges of Docker, Kubernetes, and CI/CD pipelines, and who want to transition legacy systems into modern, scalable cloud architectures. **You might be a good fit if you...** * Have 7+ years of experience with the .NET ecosystem (C#, .NET Core) and React.js. * Are proficient in designing RESTful APIs and managing complex data across SQL and NoSQL databases like MongoDB or Snowflake. * Enjoy working in a collaborative Agile environment and have a strong grasp of containerization (Docker, Kubernetes). * Live in or are willing to work on-site in Bengaluru.
