Senior Backend Engineer(Platform) – Communications AI Infrastructure

RingCentral; Bengaluru; On-site; INR 4,000,000 - 6,400,000; Full time

Job summary

RingCentral Bengaluru is seeking a Senior Backend Engineer to build and scale AI-powered communications infrastructure. You will design low-latency backends, high-throughput data pipelines and cross-region coordination for real-time calls, messaging, and media workflows.

The role demands deep expertise in distributed systems, modern backend languages, and strong observability; you will contribute to REST APIs, identity, and rate-limiting primitives while ensuring reliability.

Qualifications

• 9-13 years of backend experience in large-scale distributed systems.
• Strong system design and scalable service architecture.
• Proficiency in Java, Kotlin, Python or Go.
• Experience with event-driven/messaging systems (Kafka, Kinesis, Pulsar, RabbitMQ).
• Performance profiling, observability, metrics, tracing and logging.

Responsibilities

• Build ultra-reliable, low-latency backends for real-time calls, messaging, and media workflows at scale.
• Design high-throughput event pipelines for real-time signaling, analytics and AI processing.
• Design distributed coordination and routing systems across regions.
• Develop scalable platform primitives like RESTful APIs, identity, sessioning, rate limits and storage.
• Create end-to-end observability for a multi-region UCaaS platform under heavy load.

Job description

SeniorBackend Engineer - Communications AI Infrastructure

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.
• Good 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

Why You'll Love Working With Us

• You'll build things that scale globally
• You'll work on real problems: scale, efficiency, optimization.
• You'll be part of a global team collaborating with top engineers
• Accelerated career growth due to highly visible projects.
• Hybrid work from our Bengaluru office + flexible hours.
• Full medical insurance for you and your family
• Competitive compensation + performance bonuses

If you are passionate about building production-ready scalable systems that redefine human connection, this is your moment.
