Let’s build what’s next, together.

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.

• 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

• 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

• 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

• 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

• 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.

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