? Bengaluru, India | ? Full-Time | ? Engineering

Reimagine How The World Communicates with AI

We're reimagining how people communicate using AI; from smart assistants that schedule meetings and transcribe conversations to systems that understand voice, video and text in real time. Such applications need a foundational distributed infrastructure that powers millions of concurrent calls and processing volumes of data. We’re looking for a backend engineer who can design and scale these core systems.

Join our Bengaluru engineering team to build the backbone of AI driven communication.

What You’ll Do
- Build ultra-reliable, low-latency backends for real-time calls, messaging, and media workflows at scale.
- Design high-throughput event pipelines that power real-time signaling, analytics and AI feature processing with minimal lag.
- Design distributed coordination and routing systems that maintain consistency and performance across regions.
- Develop scalable platform primitives like RESTful APIs, identity, sessioning,



rate limits and storage that serve as foundations for AI-powered applications.
- Create end-to-end observability that keep a multi-region UCaaS platform predictable under heavy load

What You Bring
- 9–13 years of hands-on backend engineering building and operating large-scale distributed systems
, with a deep understanding of consistency, partitioning, replication and high availability fundamentals.
- Positive system design expertise
, with the ability to architect fault-tolerant, horizontally scalable services.
- Expert proficiency in at least one modern backend language
(e.g., Java, Kotlin, Python, Go), with the ability to write high-performance code and lead technical reviews across complex systems.
- Experience designing and scaling high-throughput or low-latency services
, including API design, concurrency models, resource management and performance tuning across distributed workloads.
