DATA ANNOTATION TEAM LEAD

Lead a team of annotators building the datasets that train frontier AI models. At Biz-Tech Analytics, we partner with global AI labs on high-stakes annotation projects — RLHF, model evaluation, and custom dataset creation. This isn't bulk labeling. It's precision work that directly shapes how the world's best AI models learn.

RESPONSIBILITIES

• Lead, mentor, and manage a team of data annotators across image, video, text, and specialized projects

• Conduct regular quality audits to maintain annotation accuracy above target thresholds

• Train team members on annotation tools, processes, and specialized project guidelines

• Collaborate with project managers to plan deliverables and meet client deadlines

• Identify and implement process improvements to increase throughput without compromising quality

• Handle escalations and ensure deadlines are met — quality is non-negotiable

REQUIREMENTS

• 2–5 years of hands-on experience in data annotation (image, video, text, audio, or specialized domains)

• Proven experience leading or managing annotation teams (not just individual annotation work)

• Strong working knowledge of annotation tools (Labelbox, CVAT, Scale AI, Appen, or similar)

• Track record of maintaining quality standards and running structured QC workflows

• Excellent communication and organizational skills

• Must work from our Delhi office — this is a fully in-person role (no remote or hybrid options available)

NICE TO HAVE

• Experience in specialized annotation: coding, medical, STEM, or multilingual domains

• Exposure to AI/ML workflows, RLHF, or model evaluation pipelines

• Experience scaling annotation teams from small to large

THIS ROLE ISN'T FOR YOU IF

• You've never managed or led a team — individual annotation experience alone isn't sufficient

• You're looking for a remote or hybrid position — this role requires daily in-office presence in Delhi

• You don't have hands-on experience with professional annotation tools

• You're not comfortable with strict quality benchmarks and tight deadlines
