• Work with developers to enable real-time call streaming and backend connectivity
• Troubleshoot SIP-level issues and optimize signaling flows

Requirements

• Deep understanding of SIP, RTP, VoIP protocols, and signaling

• Hands-on experience with:

  • Asterisk, FreeSWITCH, Kamailio, or OpenSIPS
  • Telecom tools like sngrep, Wireshark, SIPp
  • Managing SBCs, gateways, NAT traversal, STUN/TURN configs

   

• Familiarity with:

  • Telecom APIs (Twilio, Plivo, SignalWire, Telnyx)
  • DID provisioning, call routing, failover logic

   

• Bonus: Understanding of eSIM/SIM management, mobile infra
• Bonus: Comfort working with backend languages (Python, Go, Node.js)

What You Get

• Project-based contract with remote flexibility
• Competitive compensation 
• Direct access to founders and a technical-first culture
• Fast decision-making and high-impact work
• A potential path to long-term collaboration in a core engineering role
