You’re a fast learner who thrives in fast-paced startup environments, where uncertainty is the norm, and there’s no user manual. You’re driven by curiosity and passion—about AI or anything else that excites you—and you’re eager to learn and grow every step of the way. You’re comfortable rolling up your sleeves, figuring things out on the fly, and don’t shy away from talking to anyone in the organization to make things happen. If you’ve integrated AI into your daily life and know how to turn curiosity into action, we want to hear from you.

• Lead the prioritization and execution of tasks based on the Core/AI team’s operating model.

• Continuously seek ways to optimize our core systems based on key metrics

• Develop and maintain robust product documentation and requirements that improve internal processes and help to provide scope for engineering development.

Requirements:

• Bachelor’s degree in Computer Science, Engineering, Mathematics, or a related technical field (or equivalent practical experience).

• 5+ years in a technical product management role, preferably with experience in AI or core infrastructure teams.

• Strong understanding of software development, AI technologies, and system architecture.

• Strong problem-solving skills and willingness to roll up sleeves to get the job done.

• Skilled at working effectively with cross-functional teams and ability to influence.

• Experience gathering business requirements, defining product requirements and using business intelligence tools (SQL, Amplitude, Looker, Braze) to extract data, formulate metrics, and build reports.

• Experience leading multiple projects with multiple stakeholders within tight timelines

• Extreme attention to detail, design and UX.

• Genuine user-centric and data-driven mindsets.

• Excellent written and verbal communication skills. Full professional proficiency in English. Spanish and/or Portuguese is a plus.
