Remote role with a common backend title and metro hiring increases competition, though WebRTC/Elixir specialization reduces candidate density.
Strong real-time communications and WebRTC focus makes domain-specific experience critical and less transferable across industries.
Multiple mandatory technical skills (WebRTC, Elixir/Erlang, distributed systems, networking, observability) will heavily filter applicants.
Own and operate backend services supporting WebRTC and Voice SDK products including authentication, token management, push notifications, proxying, RTC DNS, and diagnostic logging.
Improve reliability, scalability, observability, and architecture of real-time communication backend systems, including deployment, monitoring, troubleshooting, and production support.
Collaborate closely with mobile and JavaScript SDK engineers to enhance connection setup, routing, authentication flows, and overall service behavior in distributed communication environments.
Professional experience building and operating backend systems in production.
Experience with backend technologies and ability to work or ramp up quickly on Elixir or Erlang.
Strong understanding of networking fundamentals and distributed systems relevant to real-time communication.
Work Experience Required: Not explicitly mentioned in the JD.
Experience designing and maintaining distributed, low-latency, real-time communication systems such as WebRTC or VoIP.
Strong background in backend engineering with ownership of services through design, deployment, and monitoring lifecycle phases.
Proficient with observability tools, Kubernetes, containers, CI/CD pipelines and familiarity with push notification services like APNs or FCM.
