    About ClearGrid

    ClearGrid is on a mission to revolutionize the debt resolution industry. We're using AI, automation, and real‑time data to completely rethink how debt collection works, unlocking better outcomes for institutions and individuals alike. Think of us as rebuilding the collections—starting from scratch, with modern tools.

    We're a fast‑growing startup with ambitious goals, and we're looking for builders who are hungry to make a real dent in a space with massive untapped potential.

    Role Overview

    We are seeking a highly skilled and experienced Telecom & Infrastructure Engineer – Voice & Telco Systems. This role owns the end‑to‑end telecom and voice infrastructure that connects on‑premise telco providers (ISDN) to our cloud‑hosted PBX and AI systems. The engineer will be responsible for designing, maintaining, troubleshooting, and scaling voice connectivity, while acting as the technical owner for telco vendors, especially across UAE and Saudi Arabia. This is a hands‑on role. We are not looking for a paper architect or a pure IT admin — we need someone who understands real‑world telco problems, knows how carriers work in the Middle East, and can independently drive solutions.

    Key Responsibilities
    • Telecom & Voice Infrastructure – Own and maintain ISDN PRI (E1) connectivity terminated at office locations; configure and manage ISDN gateways / PBX hardware used for ISDN SIP conversion; ensure clean ISDN signaling (Q.931 / Euro ISDN / QSIG); handle DID mapping, CLI presentation, channel capacity, and scaling.
    • SIP, PBX & Cloud Integration – Manage SIP trunks between on‑prem gateways and cloud‑hosted PBX (AWS); troubleshoot SIP signaling, RTP media, codecs, DTMF, and audio issues; debug common issues such as one‑way audio, call drops, call setup failures; work with Yeastar / Asterisk / FreeSWITCH‑based systems (or similar).
    • Network & VPN Connectivity – Ensure stable site‑to‑site VPN connectivity for SIP/RTP traffic; coordinate with firewall setups (Fortinet or equivalent); understand NAT traversal and voice‑specific networking constraints.
    • Vendor & Telco Management & Operations (Critical Part of the Role) – Serve as the main technical liaison for vendors; proactively identify, evaluate, and integrate ISDN/voice carriers; manage and coordinate the end‑to‑end process: provisioning, migrations, testing, and cutovers; resolve escalated issues by engaging directly with carrier NOCs and field engineers; enforce quality standards, challenging vendors on unacceptable routing, signaling, or service quality.
    • Operations & Documentation – Perform root‑cause analysis for telecom incidents; create and maintain architecture diagrams and runbooks; document call flows, vendor dependencies, and recovery procedures; support expansions, new office setups, and vendor transitions.
    Requirements
    • Strong hands‑on experience with ISDN PRI (E1) configuration and troubleshooting.
    • Solid understanding of SIP, RTP, codecs, DTMF, and call flows.
    • Experience working with PBX systems (Yeastar, Asterisk, FreeSWITCH, Cisco, etc.).
    • Direct experience dealing with telco providers (not via middlemen only).
    • Mandatory: Regional Vendor Knowledge (UAE & KSA).
    • Proven knowledge of where and how to procure ISDN / voice connectivity in: UAE (DU, Etisalat); Saudi Arabia (STC, Salam, Mobily, Zain).
    • Familiar with local telco procurement processes; DID allocation and CLI regulations; provisioning lead times and dependencies; common carrier limitations and workarounds.
    • Able to independently: shortlist vendors; coordinate installations and migrations; manage carrier escalations end‑to‑end.
    • Preferred Experience: site‑to‑site VPNs for voice traffic; AWS networking basics; Fortinet or enterprise firewall exposure; experience with AudioCodes, Sangoma, or Patton gateways; SBC or carrier interconnect experience.
    Why Join ClearGrid?
    • Real ownership: You'll play a central role in building products that redefine how collections work in the future.
    • Massive industry impact: This is one of those rare spaces where almost everything is still to be built.
    • High‑growth team: We're scaling fast, and the systems, tools, and processes you help create will shape our foundation.
