Description

  (a) data-side analysis - interrogating the comparison results; and

  (b) vendor engagement - obtaining inventory files from the carrier, clarifying their column semantics, disputing and driving carrier-side corrections, and tracking SLA.

 

Both postholders perform the full role. The split below is a division of ownership, not of skill set - each must be able to cover the other during absence.

   1- Primary owner of the active wave's carrier relationship and of the equivalence-rule set for that carrier.

    - Owns the weekly burn-down pack and the monthly KPI feed submission.

    - Runs the onboarding of the next carrier in parallel with the tail of the current wave (file request, column dictionary, mapping draft).

 2  - Primary owner of mismatch triage volume: classification, severity assignment, ticket raising, and ageing management.

    - Owns the tag-and-locate queue: shortlisting residual unmatched circuits, grouping them by site, and coordinating the Field Ops batches.

    - Owns the completeness reporting on LEC carrier and LEC circuit ID fields.

 

SKILL SET

 Essential

    Data and tooling

       - Advanced Excel - large workbooks, lookups, pivot tables, text normalization functions; comfortable working with 100k+ row extracts.

       - Working comfort with CSV/Excel data exchange, encoding and delimiter issues, and with inconsistent or dirty carrier-supplied files.

 

    Domain

       - Telecom inventory fundamentals: circuit IDs, circuit types (Ethernet, Private Line, MPLS, DIA, Channelized, SONET), bandwidth notation, A-end / Z-end service addresses, LEC / local-loop concepts and demarc.

 

    Method

       - Data quality practice: profiling, rule definition, exception triage, false-positive management, root-cause analysis.

       - Exceptional attention to detail and evidential discipline – every correction raised must carry the evidence that justifies it.

       - Structured, self-directed working

 

    Vendor and stakeholder

       - Vendor / supplier management: chasing deliverables, running working calls with carrier data teams, disputing records with evidence, and tracking commitments to an SLA.

       - Clear written English; able to produce a status pack that an executive can read without a walkthrough.

 Desirable

       - Python with pandas for ad-hoc analysis (production pipeline code is not expected of this role).

       - Prior exposure to comparable telecom expense management / inventory platforms.

       - Experience of a carrier inventory reconciliation, circuit rationalization or telecom audit programme.

       - Familiarity with address standardization and fuzzy-matching techniques.

       - Experience operating inside a KPI / scorecard governance framework.

       - Basic HTML or dashboard literacy sufficient to sanity-check published output

 

EXPERIENCE AND BEHAVIOURS

       - 3+ years in a data quality, data analyst or telecom inventory role; at least 1 year with vendor-facing responsibility.

       - Persistent and comfortable with ambiguity - much of the value of this role is in resolving the records that do not reconcile cleanly.

       - Able to use escalation as a
