What this role is all about

As a Product Sales Specialist (Voice Wholesales), you will own the commercial performance, growth, and profitability of Infobip’s global Voice wholesale business.

This is a hands‑on role with real ownership over traffic growth, routing strategy, pricing, and margin optimization. You will manage Tier 1 carrier and aggregator relationships, work closely with Routing, NOC, and Revenue Assurance teams, and actively influence how voice traffic is routed and monetized across global markets.

This is not a transactional sales or account‑admin role.

This role is designed for a professional with a deep understanding of the international voice wholesale ecosystem.

What you'll do:

Voice Wholesale & Customer Ownership

Own and grow a portfolio of Tier 1 Voice wholesale partners (international carriers, aggregators, operators)
Drive traffic growth while protecting and improving gross margin (GP)
Actively manage pricing, bilateral agreements, and commercial terms
Identify and develop new routing opportunities and destinations
Build long‑term, trusted partnerships across the global carrier ecosystem

Traffic, Routing & Quality Management

Monitor and analyze traffic performance and voice quality KPIs (ASR, ACD, PDD, NER)
Work directly with Routing and NOC teams to optimize LCR, quality, and margin
React immediately to traffic drops, quality degradation, or margin erosion
Support onboarding of new interconnections and live traffic launches

Risk, Fraud & Market Awareness

Closely collaborate with Revenue Assurance to detect and prevent fraud, grey routes, and revenue leakage
Stay on top of market dynamics: price erosion, CLI manipulation, regulatory changes, and competitor behavior
Proactively flag risks and propose corrective actions

Internal Collaboration & Tools

Coordinate cross‑functional teams: Routing, NOC, Finance, Procurement, RA, Platform Operations
Maintain accurate forecasting, reporting, and opportunity tracking in Salesforce and internal tools
Act as a power user and provide feedback to improve traffic monitoring and analytics tools

What makes you a strong fit:

4+ years of experience in international Voice Wholesale (carrier / aggregator business).
Strong understanding of A2P/P2P Voice, CLI, routing strategies, LCR, bilateral interconnects, and pricing models.
Proven experience managing high‑volume, margin‑sensitive voice traffic.
Deep knowledge of voice quality metrics (ASR, ACD, PDD) and how to improve them.
Strong commercial mindset with clear ownership of revenue, margin, and traffic growth.
Comfortable working in fast‑moving, dynamic pricing environments.
Ability to navigate complex internal organizations and work cross‑functionally.
Fluent in English; additional languages are a plus.

Nice to have:

Existing network within the international carrier ecosystem
Experience with fraud prevention and RA processes
Understanding of regional voice regulations
