✨ About the Role

As Virtual Numbers Supply & Compliance Manager, you will own the supply-side of Yesim’s virtual numbers business — ensuring access to quality numbering in the right countries at competitive cost, within legal requirements, and through a technically reliable supply chain.

You will connect four areas that are typically handled by different people: numbering suppliers, number quality, country-level regulation, and technical implementation.

The role owns the input into the supply chain: procurement, quality, legality, and technical availability. Commercial packaging, end-customer pricing, marketing, and B2B sales remain with Product and Commercial.

This is a Senior individual contributor role, working full-time remotely and reporting to the Chief of Telecom Development.

📝 Responsibilities

Supplier Market & Procurement

• Build and maintain a supplier map: direct operators, local carriers, DID providers, CPaaS platforms, and aggregators — by coverage, number types, available inventory, provisioning speed, KYC requirements, and actual total cost

• Conduct RFI / RFP and technical-commercial comparisons; determine where to procure through an aggregator and where direct operator relationships make sense

• Negotiate the full commercial package: setup fees, monthly number rental, per-minute and per-message rates, channel capacity, deposits, minimum commitments, volume tiers, penalties, number return conditions, and fraud liability

• Define reservation policy: second supplier per country, switching rules and timelines, and pool migration scheme without losing customer numbers

• Manage supplier relationships after signing: quality, inventory availability, incidents, periodic review of terms, and coverage expansion

Numbering Quality

• Define requirements for number cleanliness and secure them contractually: quarantine period after previous ownership, history guarantees, replacement rights, and claim procedures

• Implement pre-issuance number checks: HLR-lookup, checking existing registrations in messengers and platforms, spam and reputation databases, and attestation within STIR/SHAKEN for US numbering

• Segment pools by purpose: numbers for verification traffic, voice scenarios, and long-term use — with different requirements for range type and quality

• Understand and explain why an aggregator’s VoIP range may fail where a local operator’s mobile range passes, and build procurement accordingly

• Maintain vendor quality metrics and use them as a negotiation argument and basis for supplier replacement

Regulation & Legality

• Own the matrix: country → number type → who we can sell to → required documents → prohibited use cases

• Know local presence and proof of address requirements, KYC obligations, licensing conditions for owning and reselling numbering, and national numbering plan rules

• Account for emergency calling obligations, lawful intercept requirements, data retention, and privacy restrictions where applicable to our model

• Monitor regulatory changes and supplier policies in priority markets and translate them into product and contract changes in advance

• Work with Legal as a validator and contract-form owner: come with a formulated position and specific questions rather than asking Legal to determine what is allowed

Technical Implementation

• Understand the telecom chain: E.164 and numbering plan structure, SIP trunking, SBC, origination and termination, number types, routing, porting, and number hosting

• Understand delivery mechanics: SMPP and HTTP webhooks for incoming SMS, delivery reports, A2P vs P2P restrictions, and differences between vendors in handling service traffic

• Set development tasks for integration with supplier APIs: provisioning and releasing numbers, processing incoming events, pool state synchronization, and application behavior

• Test new suppliers on real traffic before signing rather than accepting stated capabilities at face value

• Analyze incidents together with Tech and escalate them to suppliers in technical language

Pool Economics & Anti-Fraud

• Calculate number unit economics: rental × pool size × utilization, active number cost, break-even point, and payback of opening a new country

• Manage utilization: reclaim idle numbers, adjust pool size, move country pools, and review terms at low utilization

• Maintain a risk taxonomy applicable to numbering: IRSF and toll fraud, AIT and SMS-pumping on verification traffic, Wangiri, customer abuse, and unauthorized resale

• Define preventive measures together with Product and Risk: destination restrictions, limits, geo-rules, number reputation checks, and manual review of suspicious cases

• Ensure clear allocation of fraud liability in supplier contracts and account for this exposure in the final cost

📩 What We’re Looking For

• 3–5+ years in DID, VoIP-wholesale, CPaaS, or virtual numbers — on the supplier or procurement side

• Own network of contacts among numbering suppliers; ability to name specific companies, specific terms, and specific people

• Practical experience negotiating numbering contracts: rental, commitments, deposits, penalties, return conditions, and fraud liability

• Working knowledge of number quality: number history, quarantine, range reputation, and the difference between geographic, mobile, and toll-free numbers and its impact on verification

• Knowledge of country-level regulation at the level of your own expertise, rather than relying on Legal for the first answer

• Technical literacy: SIP, provisioning, porting, incoming SMS, and supplier APIs. Coding is not required

• Strong numerical skills: number cost, utilization, margin, and ability to read CDRs and supplier invoices

• Excel is required; SQL is a plus

• English — Upper-Intermediate and above for negotiations, contract work, and industry events

Would Be a Plus

• Experience negotiating directly with operators and local carriers, rather than only with aggregators

• Experience with number porting and direct interaction with regulators

• Experience with anti-fraud in voice or messaging traffic

• Experience launching numbering within a consumer app, travel-tech, eSIM, or fintech

• Experience with KYC processes and country launches

🎁 What We Offer

• Direct work with the Chief of Telecom Development

• High autonomy and ownership over the virtual numbers supply function

• A fast-growing international product company

• Fully remote work

• Competitive compensation

• Opportunity to build and scale the supply function as the business grows
