Customer Success Manager - Brazil

About the Role

• We're looking for a Senior Customer Success Manager (Portuguese Speaking) to own and grow a portfolio of customer accounts at a U.S.-based AI-powered advertising technology platform. You'll combine customer relationship management, digital advertising expertise, and commercial thinking to help customers get more value from the Smartly platform — solving challenges, improving campaign outcomes, and identifying opportunities for growth.
• You'll be a trusted advisor to your customers and a voice for them inside the business.

About You

• You have experience managing and developing B2B customer relationships, ideally within SaaS, digital advertising, marketing technology, or an agency environment.
• You take a consultative approach to customer success — you listen, understand the business behind the ask, and translate that into practical solutions.
• You're commercially aware and naturally spot opportunities to deepen product adoption and expand customer relationships.
• You communicate clearly and confidently in both Portuguese and English, across different audiences and levels of seniority.
• You're curious about digital advertising and technology, and you invest in building deep knowledge of the products and ecosystems you work with.

What You'll Be Doing

• Manage and develop a portfolio of customer accounts, building trusted relationships through regular communication and a strong understanding of each customer's business and advertising goals.
• Advise customers on their digital advertising strategies, helping them address challenges related to campaign performance, budget scaling, operational efficiency, and platform adoption.
• Identify opportunities to grow customer relationships by expanding product adoption and connecting Smartly's solutions to customers' evolving business needs.
• Scope and lead product trials, supporting customers through adoption and helping them realize measurable improvements in their advertising workflows and outcomes.
• Build and maintain deep knowledge of the Smartly platform and the broader digital advertising ecosystem to confidently guide customers and solve complex challenges.
• Collaborate with Customer Success, Product, and cross-functional teams to share customer insights, resolve challenges, and maintain a strong feedback loop between customers and the business.
• Develop vertical and market knowledge across your customer portfolio to provide relevant, context-aware recommendations and strengthen long-term partnerships.
• Travel as needed for customer meetings, conferences, and industry events.

What We're Looking For

• A relationship builder who earns trust quickly and maintains it over the long term through consistency, expertise, and genuine care for customer outcomes.
• Strong problem-solving instincts — you identify what a customer actually needs, not just what they asked for.
• Commercial sensibility and the confidence to identify and pursue growth opportunities within existing accounts.
• A collaborative mindset — you work well across internal teams and bring customer perspective into product and business conversations.
