Project Lead (AI Model Training)

Join NewtonX, a rapidly growing company that is revolutionizing AI deployment. As a Project Lead, you will own client engagements from scoping to delivery, manage multiple concurrent projects, and help build and scale the delivery function. You will have direct exposure to the C-level and a clear career path in a fast-growing business.

• Scope and set up every engagement, translating client needs into a bounded statement of work and configuring the project on the platform.
• Run production, owning quality, throughput, and cost, and managing the annotator pool on your projects.
• Own the client relationship, being the point of contact throughout the project, managing expectations, and surfacing expansion opportunities.

• Valid US or Canadian work authorization required. Visa sponsorship is not available for this role
• Exceptional at holding many threads. You will run several concurrent projects with different clients, quality bars, and annotator pools
• Analytically rigorous. Data analysis skills using SQL or Python are a strong plus
• An operator who goes into the weeds. You are comfortable owning quality metrics, debugging a stalled queue, and rewriting a rubric that is not holding up in production
• Adaptable and resilient. Specs change, clients change their minds, and no two weeks look the same. You roll with it and find the new angle
• Discreet. This role handles annotator personal data and client-confidential information under strict data-security and confidentiality standards; all work stays within approved systems
• Client-facing and credible. You can run a scoping call with a technical buyer, deliver bad news without losing the room, and translate operational mechanics into terms a client cares about
• 3+ years of experience in data labeling, RLHF/SFT, or AI evaluation delivery — you have shipped real annotation or evaluation projects at a data labeling company (Scale, Surge, Mercor, Snorkel, Handshake, Centific, Labelbox, SuperAnnotate, or similar) or inside an AI lab. This is a firm requirement; we are not looking for a generalist project manager
• A builder. Processes here are young and some are still manual. You want to stand things up rather than inherit a finished machine
