About your day-to-day:

We’re hiring an Account Manager to own and grow a book of Enterprise and Mid-Market customers at Port. In this role, you will be responsible for renewals, expansion ARR, and net revenue retention (NRR), partnering closely with Sales, Customer Success, and Product to maximize customer value and revenue growth.

This is a role for someone who thrives in post-sale commercial ownership, enjoys managing complex customer relationships, and knows how to translate product adoption into renewals, upsells, and cross-sells. You will act as a strategic partner to your customers while driving measurable revenue impact for the business.

• Own a quota-carrying book of business, driving renewals, expansion ARR, and net revenue retention (NRR).
• Lead the renewal and expansion motion end-to-end, including forecasting, deal strategy, and contract negotiations.
• Identify and close upsell and cross-sell opportunities through account planning, white-space analysis, and a deep understanding of customer needs.
• Build strong relationships with economic buyers and executive stakeholders, serving as a trusted advisor and leading value-focused business reviews.
• Partner cross-functionally with Sales and Customer Success to drive adoption, mitigate renewal risk, and execute multi-threaded expansion strategies.
• Translate product usage and outcomes into clear business value tied to commercial outcomes.
• Collaborate with Product, Sales, and Support to deliver a seamless post-sale experience.
• Act as the voice of the customer, sharing feedback that informs product direction, adoption improvements, and expansion strategy.

• 5+ years of experience in Account Management, Customer Success with commercial ownership, or post-sale SaaS sales, ideally in Enterprise or Mid-Market segments.
• Spanish Fluency is a must. Additional fluency in Portuguese is a major plus.
• Proven track record of owning renewals and expansion targets, with measurable impact on ARR and NRR.
• Experience managing complex, multi-stakeholder accounts and negotiating commercial agreements.
• Comfort carrying a quota and forecasting revenue across a renewal and expansion pipeline.
• Strong executive presence with the ability to influence economic buyers and senior stakeholders.
• Experience in B2B SaaS; familiarity with developer tools, DevOps, or technical products is a strong plus.
• Highly organized, data-driven, and strategic, with the ability to manage multiple accounts and priorities at scale.
