B2B – Customer Success & Account Management

About arenaflex

arenaflex is a fast-growing EdTech company on a mission to make English learning accessible to students around the world through live, one-on-one conversations with native speakers. As we expand our B2B footprint in Brazil, we’re looking for an experienced Customer Success Account Manager (CSAM) to own the full post-sales experience—from onboarding and platform engagement to account renewals and upsells. This is a hybrid role that combines Customer Success and Account Management responsibilities to provide strategic and hands-on support for a portfolio of B2B clients in Brazil. As a key member of our B2B team, you will play a critical role in driving client satisfaction, retention, and growth, while contributing to the overall success of arenaflex in the Brazilian market.

Why This Role?

We’re combining CS + AM functions in select markets like Brazil due to:

• A relatively small and manageable customer base
• Low deal complexity
• Budget and resource efficiency

This role is ideal for someone who thrives in a fast-paced, client-facing environment and wants end-to-end ownership of client success and retention. If you're passionate about delivering exceptional customer experiences, driving business growth, and working in a dynamic, mission-driven team, this is the perfect opportunity for you.

What You’ll Do

As a Customer Success Account Manager at arenaflex, you will be responsible for:

• Guide onboarding and adoption: Lead platform setup for admins and learners to ensure a quick time-to-value.
• Account segmentation and strategy: Segment accounts by revenue potential and create targeted engagement strategies.
• Drive engagement and outcomes: Monitor usage, conduct quarterly business reviews, celebrate learner milestones, and ensure platform value is being realized.
• Support and communication: Be the go-to contact for admin requests and ensure timely, solution-oriented support.
• Monitor account health: Provide regular usage and performance reports to support internal advocacy within client organizations.
• Satisfaction tracking: Run student and admin satisfaction surveys to collect feedback and inform future improvements.
• Renewals and upsells: Own renewal conversations and identify opportunities for account growth through upsells.
• CRM management: Keep HubSpot and internal CRM tools updated with accurate client data, engagement activities, and renewal forecasts.
• Performance tracking: Track and report against key KPIs such as platform utilization, satisfaction, renewal rates, and upsell performance.

What We’re Looking For

We're seeking a highly motivated and experienced Customer Success Account Manager with a strong track record of client retention and renewal success in a B2B setting. The ideal candidate will have:

• 2–4 years of experience in Customer Success and/or Account Management, with a strong focus on client retention and renewal success.
• Demonstrated ability to articulate product value, manage account health, and lead strategic client conversations.
• Comfortable with data analysis, CRM hygiene, and using metrics to drive decisions.
• Skilled in presenting to stakeholders, conducting QBRs, and managing multiple accounts in a structured way.
• Fluent in Portuguese and proficient in English (spoken and written).
• Highly organized, proactive, and client-centric.
• Must be based in Brazil and familiar with the local business and education landscape.

Why arenaflex?

* A global, mission-driven team making a meaningful impact on learners worldwide

• Pre-IPO company with high growth and equity opportunities
• Ownership and autonomy in a cross-functional, collaborative culture
• Chance to grow your career with a company expanding its B2B presence in Brazil
