SeniorBackend Engineer – Communications AI Infrastructure

? 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.
- Proven ability to build event-driven or asynchronous architectures using distributed messaging or streaming systems(e.g., Kafka, Kinesis, Pulsar, RabbitMQ).
- Hands-on performance and observability skills, including profiling, eliminating bottlenecks, optimizing tail latency and implementing robust metrics, tracing, and logging for distributed systems

Nice to Have

- Understanding of networking fundamentals and cross-region or multi-DC architectures, including latency tradeoffs and data movement considerations
