Description

  • Build and maintain real-time telephony workflows for live outbound calling over PSTN.
  • Work on a Rust-based backend stack using Axum, Tokio, and SQLx.
  • Develop event-driven services and coordination logic using Redis streams.
  • Design and support Postgres-backed state in Aurora for production systems.
  • Integrate with Twilio SIP trunking, VoIP, and LiveKit room lifecycle management.
  • Implement and maintain a custom power-dialer kernel with parallel and sequential state machines.
  • Support ML integrations for transcription, scoring, copilots, and live audio workflows using OpenAI, Bedrock, SageMaker, and AssemblyAI.
  • Debug and resolve real production issues in systems where calls are active and failures are time-sensitive.
  • Collaborate in a small, high-ownership team using a spec- and docs-first approach.

Requirements

  • Strong experience with Rust and/or TypeScript.
  • Experience building backend or fullstack systems in production.
  • Solid understanding of Postgres, including lock contention and lock waits.

  • Ability to debug real production issues.
  • Experience working with event-driven systems.
  • Experience coordinating across multiple services in distributed systems.
  • Ability to work on systems that can fail in non-obvious ways.
  • WebRTC, SIP, or VoIP experience is a plus.
  • Experience with AWS services such as EKS, ECS, or Terraform is a plus.
  • React experience and ability to own features end-to-end is a plus.
  • Willingness to learn telephony concepts quickly; prior telephony experience is not required.

Benefits

  • Fully remote work for candidates in EU and Americas time zones.
  • Competitive salary of 60,000–80,000 USD plus equity.
  • Flexible working hours.
  • High ownership and autonomy.
  • Opportunity to work on real-time production systems.
