Role Overview 

We are seeking a highly skilled Backend Engineer with strong expertise in real-time media streaming, low-latency communication, and distributed backend systems using C++ or Golang. The ideal candidate must have deep hands-on experience with streaming protocols, real-time communication frameworks, and high-performance backend engineering. This role involves designing and building backend microservices that power real-time audio/video communication, streaming pipelines, and low-latency data flows across distributed systems. 

Responsibilities 

• Design, develop, and maintain high-performance backend services using Go or C++. 

• Build and optimize real-time microservices that support low-latency communication across a distributed architecture. 

• Develop and enhance WebSocket, REST, and real-time APIs used by client-facing applications. 

• Work extensively with media streaming technologies, including RTP, SRTP, WebRTC, and related protocols. 

• Implement and optimize WebRTC SFUs (Selective Forwarding Units) for scalable audio/video streaming. 

• Integrate and optimize media workflows using tools and libraries such as FFmpeg and GStreamer. 

• Work with databases such as MySQL, Redis, MongoDB, and design efficient data models for real-time workloads. 

• Ensure backend services meet high standards of security, reliability, and performance using modern DevOps and SRE practices. 

• Collaborate closely with Frontend, DevOps, and Product teams to deliver end-to-end features. 

• Write clean, well-documented, and maintainable code following best engineering practices. 

• Diagnose performance bottlenecks and optimize backend systems for scalability and speed. 

Requirements 

• 5+ years of hands-on backend development experience using Go and/or C++. 

• Strong expertise in real-time media streaming, including one or more of the following: 

• RTP / SRTP 

• WebRTC (MUST-HAVE) 

• WebRTC SFU implementation 

• Deep understanding of video/audio processing, with experience using FFmpeg, GStreamer, or similar frameworks. 

• Understanding of networking concepts, including TCP, UDP, ICE, STUN/TURN, and WebSockets. 

• Strong understanding of concurrency, asynchronous programming, and performance tuning. 

• Experience building and consuming RESTful and WebSocket APIs. 

• Hands-on experience with message queues such as Kafka, NATS, or RabbitMQ. 

• Experience working with cloud platforms (AWS, GCP, Azure). 

• Strong problem-solving skills and the ability to work on low-latency, high-throughput systems. 

• Proficient in C++ or Go for media streaming

• Familiarity with monitoring, logging, and tracing tools (e.g., Prometheus, Grafana, OpenTelemetry) is a plus. 

• A good understanding of containerization and orchestration using Docker and Kubernetes is preferred. 

• Experience working with real-time communication platforms is an added advantage.
