As a Senior Program Manager at Sigma AI SLU, you will lead complex and high-stakes data initiatives. You are a strategic partner to our clients and a visionary for our internal operations. You will be responsible for the end-to-end success of Generative AI projects, ensuring that our annotation workflows are not only accurate but also innovative and scalable.

Key Responsibilities

• Workflow Architecture & Innovation: You will design and implement innovative, automated, or hybrid workflows for "first-of-their-kind" GenAI and LLM challenges.
• Guideline & Logic Governance: Oversee the creation and auditing of sophisticated annotation guidelines. You ensure that the "reasoning" behind every data label aligns with the client's or internal needs.
• Business Intelligence: Translate raw project data into executive-level presentations that highlight trends, risks, and opportunities for operational scaling.

Requirements
