About YAL

YAL is building a decentralized, AI-powered communication platform from the ground up — combining secure real-time messaging, voice/video calling, and intelligent fraud detection. Our mission is to deliver global communication infrastructure that prioritizes privacy, security, and performance without relying on centralized servers.

We're looking for a Backend Lead – Real-Time Messaging & VoIP to join our core engineering team and own the architecture, scalability, and reliability of the backend systems that power our real-time communication stack.

What You'll Do

• Build ultra-reliable, low-latency backends for real-time calls, messaging, and media workflows at scale.

• Own end-to-end backend architecture, technical roadmap, and production reliability of the communication stack.

• Design and optimize real-time communication infrastructure using WebSockets, WebRTC, TURN/STUN, and media signaling protocols.

• Design high-throughput event pipelines that power real-time signaling, analytics, and AI feature processing with minimal lag.

• Architect distributed coordination and routing systems that maintain consistency and performance across regions.

• Develop scalable platform primitives like RESTful APIs, identity, session management, rate limiting, and storage that serve as foundations for AI-powered applications.

• Create end-to-end observability that keeps a multi-region communication platform predictable under heavy load.

• Drive architecture reviews, technical decision-making, and backend engineering best practices.

• Mentor backend engineers and contribute to building a strong, high-performing backend team.

What You Bring

• 8-12 years of hands-on backend engineering experience building and operating large-scale distributed systems.

• Deep understanding of distributed systems fundamentals: consistency models, partitioning, replication, concurrency, and high availability.

• Strong system design expertise with the ability to architect fault-tolerant, horizontally scalable services.

• Expert proficiency in at least one modern backend language (e.g.,Node Js,Rust, Python, Go, C/C++), 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, RabbitMQ).

• Hands-on performance and observability skills, including profiling, eliminating bottlenecks, optimizing tail latency, and implementing robust metrics, tracing, and logging for distributed systems.

• Experience leading backend initiatives or mentoring engineers with a strong ownership mindset and ability to drive architectural decisions.

Why Join YAL

• Help shape the architecture of a next-generation messaging and calling platform.

• Own and lead backend engineering for a privacy-first communication infrastructure.

• Work on technically challenging distributed systems problems with a deep focus on performance and security.

• Build secure systems that scale globally.

• Be part of a high-impact team solving meaningful real-time infrastructure challenges.
