Software Engineer

Software Engineer (Python – LiveKit / Real-Time Media)

Location: Karachi, Pakistan (Onsite)
Department: Engineering
Reports To: Senior Software Engineer / Architect / Development Head

Role Summary

The Software Engineer (Python – LiveKit) will be responsible for designing, developing, and maintaining real-time communication services built on LiveKit Open Source. This role focuses on backend engineering for audio/video streaming, WebRTC signaling, media session orchestration, and event-driven integrations.

Working under architectural guidance, the engineer will implement scalable, low-latency services that integrate LiveKit with backend systems, APIs, AI/voice pipelines, and operational tooling. The role requires strong Python engineering fundamentals, experience with real-time systems, and an understanding of production-grade distributed architectures.

Key Responsibilities

• Design, develop, and maintain Python backend services integrating with LiveKit Open Source.
• Implement and manage real-time audio/video session workflows, including room lifecycle, participant management, and event handling.
• Build API-driven services for LiveKit token generation, room orchestration, and access control.
• Integrate LiveKit with downstream systems such as AI voice agents, STT/TTS pipelines, call automation, or analytics services.
• Handle WebRTC-related signaling logic, session metadata, and media event callbacks.
• Develop asynchronous and event-driven components using asyncio, WebSockets, or message queues.
• Optimize services for low latency, concurrency, and high availability.
• Implement logging, monitoring, and metrics for real-time services.
• Collaborate with frontend, DevOps, QA, and AI teams to deliver end-to-end real-time features.
• Ensure all deliverables meet internal security, performance, and reliability standards.
• Write clear technical documentation for APIs, workflows, and operational behavior.
• Participate in code reviews, debugging, and production issue resolution.

Required Skills & Experience

• 3–5 years of professional backend software engineering experience.
• Strong proficiency in Python for production systems.
• Hands-on experience with LiveKit Open Source (server, SDKs, or backend integrations).
• Solid understanding of real-time communication systems (WebRTC fundamentals, signaling, media sessions).
• Experience building REST APIs and WebSocket-based services.
• Familiarity with async programming patterns in Python.
• Experience integrating third-party services and internal APIs.
• Strong Linux environment experience and cloud-native mindset.
• Ability to debug real-time, stateful systems under production load.
• Strong analytical thinking and structured problem-solving skills.
• Clear written and verbal communication skills.

Preferred / Nice-to-Have

• Experience with AI voice systems, STT/TTS pipelines, or conversational platforms.
• Familiarity with Kubernetes, Docker, CI/CD pipelines.
• Exposure to Redis, message queues (RabbitMQ/Kafka), or event-driven architectures.
• Experience working with telephony, VoIP, or contact-center platforms.
• Understanding of observability tooling (Prometheus, Grafana, ELK, OpenTelemetry).
