Senior Elixir / Phoenix Engineer (Real-Time AI Platform) Location: Remote / Bangalore Company: Isometrik.AI by Appscrip About Us Isometrik.AI is a next-gen AI platform designed for mid-market companies to build, orchestrate, and scale AI teams. Our system powers advanced real-time chat, calling, live-streaming, and multi-channel campaign execution (voice, email, WhatsApp). The core engine is built on Elixir (Phoenix) with a distributed data layer comprising CitusDB and MongoDB, running on modern Kubernetes infrastructure. We are growing fast and looking for a strong backend engineer who can help maintain, optimize, and evolve our real-time systems. 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.

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 - Flexible remote-first work environment.
