Role Overview :

You will be a key contributor responsible for enhancing our Elixir-based real-time engine, improving system reliability, and building new features across chat, live-stream, calling infra, sockets, and campaign orchestration workflows.

This is a hands-on role with significant ownership in a high-scale, low-latency environment.

Key Responsibilities :

• Build & maintain Elixir/Phoenix services that power chat, calling, streaming, and campaign execution.
• Optimize real-time communication pipelines using MQTT (preferred) or similar protocols.
• Work with distributed databases - CitusDB (PostgreSQL extension) and MongoDB including schema design, query optimization, and performance tuning.
• Improve system scalability through clustering, message queues, supervision trees, and concurrent processing patterns in Elixir/OTP.
• Manage Kubernetes deployments - CI/CD pipelines, scaling strategies, monitoring & observability.
• Collaborate with AI, front-end, and DevOps teams to ship features rapidly.
• Debug production issues, implement fail-safe mechanisms, and ensure uptime of mission-critical systems.
• Write clean, well-tested code and participate in code reviews & architectural discussions.

Required Skills & Experience :

• 3-8 years of backend development, with at least 2+ years in Elixir/Phoenix.

• Strong understanding of OTP, GenServers, PubSub, Channels, distributed systems.

• Experience with real-time messaging protocols - ideally MQTT.

• Hands-on experience with PostgreSQL / CitusDB and MongoDB.

• Solid exposure to Docker & Kubernetes for large-scale deployments.

• Experience with event-driven architectures, microservices, or high-concurrency systems.

• Comfortable working in a fast-paced startup-style environment.

Nice to Have :

• Experience with WebRTC, SIP, or telephony/calling infrastructure.
• Experience managing high throughput messaging systems at scale.
• Familiarity with observability stacks (Prometheus, Grafana, OpenTelemetry).
• Contributions to open-source Elixir libraries.

What We Offer :

• Opportunity to work on one of the most advanced AI orchestration platforms.
• Ownership of core real-time systems powering thousands of concurrent users.
• A collaborative environment with engineering-first culture.
• Competitive salary
