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)

Kubernetes
infrastructure.

We are growing fast and looking for a strong backend engineer who can help maintain, optimize, and evolve our real-time systems.

  4. Improve system scalability
    through clustering, message queues, supervision trees, and concurrent processing patterns in Elixir/OTP.
  5. Manage Kubernetes deployments
    — CI/CD pipelines, scaling strategies, monitoring & observability.
  6. Collaborate with AI, front-end, and DevOps teams
    to ship features rapidly.
  7. Debug production issues
    , implement fail-safe mechanisms, and ensure uptime of mission-critical systems.
  8. Write clean, well-tested code
    and participate in code reviews & architectural discussions.
