DESCRIPTION
As a Senior Customer Success Manager, Strategic Accounts Voice, you will serve
as the trusted commercial and technical advisor for Sinch’s largest enterprise
voice customers. Reporting to the Director of Voice Customer Success or the Sr
Director, Strategic Accounts Customer Success, you will own the day-to-day
management of a portfolio of our most complex, high-impact accounts, combining
solid voice technical knowledge with the executive presence and commercial
acumen of a strategic account leader.
You will understand each customer’s business objectives and translate them into
voice solutions that deliver measurable outcomes. You will proactively monitor
account health, identify risks early, and act decisively to protect and grow the
relationship, owning renewals and upsells and partnering with Sales on
cross-sell opportunities. Your ability to orchestrate cross-functional teams,
communicate at the C-level, and act as the voice of the customer inside Sinch
will be critical to sustained client success and revenue growth.
This position is ideally suited to senior voice account leaders who bring deep
command of enterprise complexity, can move seamlessly between technical dialogue
and high-stakes commercial negotiation, and take true ownership of the client
relationship—engaging directly on-site when the business demands it.
Core Competencies:
Strategic Account Management: Own high-value relationships by aligning with
each customer’s long-term goals, customizing tailored solutions, and driving
mutual growth. Build trust at every level, with peer-level relationships
across the customer organization and the experience and acumen to engage
confidently with the C-suite.
Voice Technical Acumen & Cross-Functional Problem Solving: Bring deep
knowledge of SIP trunking, interconnect, and API integrations to understand
the customer’s voice environment, frame technical issues clearly, and
anticipate risks. Partner closely with the Technical Account Manager,
Engineering, Network Operations, and Support to resolve technical problems,
keeping the customer informed and owning the outcome from the customer’s
perspective.
Success Planning & Churn Prevention: Collaborate with customers to define and
execute success plans tied to their desired outcomes. Examine customer health
metrics, identify risks early, and implement mitigation plans that build
loyalty, deliver continuous value, and protect retention.
Negotiation: Lead contract negotiations, balancing customer satisfaction with
Sinch’s commercial objectives and keeping the account owner informed
throughout.
Account Planning, Reporting & Governance: Own to the Client Account Plan and
strategy for Voice services, review it regularly, and keep it current. Track
and report on account performance, and prepare data and lead regular business
reviews (e.g., QBRs) and strategic account reviews.
Renewals & Growth: Own the renewal process for your accounts, from early
planning through close, and own upsell opportunities. Identify cross-sell
opportunities by understanding the customer’s business and account strategy
deeply, and partner closely with Sales and account executives to validate,
pursue, and close them.
Stakeholder Alignment & Conversation Agility: Build consensus among internal
and external stakeholders around shared goals, timelines, and deliverables.
Adapt your style, tone, and message to the audience, from network engineers
to executives, especially in high-pressure situations.
Voice of the Customer: Gather customer feedback regularly and translate it
into actionable insights that influence product, process, and service
improvements.
