• Product Collaboration: Propose and drive technical and product changes with the engineering team to improve platform capabilities, contributor workflows, and QA tooling.
• Resource Management: Hire and manage external QA resources as needed, collaborating directly with the co-founders and engineers to unblock delivery.

What You Bring

• Experience: 2 to 7 years of data operations experience specifically on the supply side at a data annotation/labeling vendor company (e.g., Scale AI, Surge AI, Appen, Micro1, TELUS Digital, DataAnnotation, or a similar AI data startup).
• Track Record: Proven success delivering six-figure+ data collection or annotation contracts end-to-end.
• Technical Domain: Direct experience managing audio, speech, voice, or multimodal data projects.
• Analytical Chops: Strong analytical skills with the ability to build dashboards and use data to solve quantitative operational problems.
• QA Design: Quality workflow design experience, including creating annotation guidelines, QA rubrics, and quality control systems.
• Mindset: Extreme ownership, resilience in the face of ambiguity, and a habit of pushing through obstacles to deliver results.
• Presence: Ability to work full-time on-site (5 days/week) in the San Mateo/Redwood City, CA area.
