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