Job Summary The deepest technical authority on the contact centre voice and CX estate — Genesys, Avaya, NICE and Zoom — across all global sites. Where L1 and L2 restore the known, this role resolves what has not been seen before, engineers out the causes of recurrence, and raises the reliability of the platform rather than only its uptime. Resolve — own L3 escalation for voice and CX incidents end to end, from SIP and media-layer diagnosis through to confirmed restoration. Engineer — design, build and harden platform configuration, integrations and recovery capability across the four platforms. Reduce toil — extend observability, automate the repetitive, and push the fix upstream so incidents stop reaching L3 at all. Primary Job Responsibilities L3 Escalation & Incident Resolution Act as final technical escalation for P1 and P2 voice, contact centre and collaboration incidents; join the major incident bridge and drive resolution under time pressure. Perform deep diagnosis at the signalling and media layer — SIP trace and ladder analysis, RTP and codec behaviour, MOS, jitter, latency and packet loss, SBC and trunk-side fault isolation. Isolate fault domain quickly across platform, carrier, SBC, network and endpoint, and drive the correct owner rather than absorbing every symptom. Produce technical RCA to the accepted standard — evidenced timeline, confirmed cause, corrective and preventive actions with dates — and feed it into problem management. Platform Engineering & Change Own configuration and engineering across the four platforms: routing and flow design, trunk and dial plan changes, integrations, recording and retention, and tenant administration. Plan and execute upgrades, patching, migrations and certificate lifecycle; keep the estate within vendor-supported versions and drive obsolescence out. Prepare and defend change records at CAB with tested implementation, validation and rollback plans; execute high-risk changes personally. Own capacity, licensing headroom and performance forecasting for voice ports, concurrency, recording storage and trunk utilisation. Reliability, Observability & Automation Define and instrument the service level indicators that matter for voice — call setup success, failure rates, media quality, recording completeness — and monitor against them. Improve alert quality: eliminate noise, close blind spots, and ensure alerts point at a cause rather than a symptom. Automate repetitive operational work — health checks, provisioning, config validation, evidence…
