You will be responsible for onboarding, supporting, and growing international B2B customers using our VoIP services (DIDs, voice termination and origination). Acting as a trusted point of contact, you will ensure customers have a smooth experience, achieve their goals, and build long-term partnerships with our company.
The role involves close collaboration with internal sales, technical, and operations teams to ensure successful service delivery and ongoing customer satisfaction.

• Act as the primary point of contact for customers, coordinating internally to resolve service, quality, or billing-related issues
• Identify expansion opportunities within existing accounts, including additional destinations, higher traffic volumes, new DID ranges, or value-added services
• Conduct regular business reviews with customers, presenting performance metrics such as call quality, ASR, ACD and traffic trends
• Educate customers on best practices for VoIP traffic optimization, fraud prevention, and quality management
• Gather customer feedback and translate it into actionable insights for product, network, and operations teams
• Represent the company in customer meetings, industry events, and conferences when required

QUALIFICATIONS

• 2+ years of experience in Customer Success, Account Management, Partner Management, or a client-facing role, preferably within the IT, SaaS, or technology industry
• Previous exposure to telecom, VoIP, or cloud communications is HUGE plus but not required; training will be provided
• Strong customer-facing skills with the ability to build trust and long-term relationships with clients and partners
• Comfortable working with technical products and coordinating with internal technical teams
• Experience managing multiple accounts or partners simultaneously
• Commercial awareness with the ability to identify growth, upsell, or expansion opportunities
• Strong written and verbal communication skills in English; additional languages are a plus
• Experience with CRM systems and customer support or ticketing tools
• Willingness to travel occasionally (up to 15–20%)

WHAT WE EXPECT FROM YOU

• Customer-first mindset with a strong sense of ownership and responsibility for account success
• Ability to quickly learn telecom and VoIP concepts and translate them into clear value for customers
• Strong organizational and follow-up skills to manage ongoing customer needs and action items
• Confidence in communicating with both business and technical stakeholders
