Data Annotation information

What does a data annotation do?

A typical workday as a Data Annotator involves reviewing datasets—such as images, audio, text, or video—and accurately labeling or categorizing information according to specific project guidelines. Most Data Annotators work independently, but they often collaborate with project managers or data scientists to clarify requirements and resolve ambiguities. Tasks may be repetitive, but adhering to precise standards is vital for maintaining data quality. Work environments can range from technology companies to remote or freelance settings, and advancement opportunities exist as team leads or quality assurance specialists for those who excel in consistency and reliability.

How much money can I make doing data annotation?

Data annotation jobs typically pay between $10 and $20 per hour, depending on the complexity of the task and the employer. Experienced annotators or those working on specialized projects may earn higher rates, especially if they have skills in specific tools or domains. Earnings can vary based on whether the work is freelance, part-time, or full-time, and some platforms offer bonuses for accuracy or speed.

What is a data annotation?

A Data Annotation job involves labeling and categorizing data, such as text, images, audio, or video, to help train machine learning models. Annotators apply tags, bounding boxes, or classifications to data based on specific guidelines. This process improves the accuracy of AI systems in recognizing patterns and making predictions. Many data annotation jobs require attention to detail and familiarity with specific domains. It is commonly used in applications like autonomous driving, natural language processing, and computer vision.

What are the key skills and qualifications needed to thrive in data annotation?

To thrive in Data Annotation, you need strong attention to detail, accuracy, and basic data handling skills, often supported by a high school diploma or equivalent. Familiarity with annotation platforms, data labeling software, or content management systems is frequently required, though specific certifications are rare. Excellent communication, time management, and the ability to focus on repetitive tasks distinguish top performers in this role. These skills are crucial because accurate and consistent data annotation directly impacts the quality of machine learning models and AI applications.

Position Overview

Autodesk's domains - architecture, engineering, construction, manufacturing, media & entertainment - provide a distinctive research environment: rich structured data, long-horizon reasoning tasks, and real-world evaluation grounded in professional workflows. Uniquely, decades of investment in physics simulation engines, CAD kernels, and computational design tools give us something most labs don't have: high-fidelity, domain-grounded verifiers that can serve as reward signals for post-training. Rather than relying solely on human preference data, we can ground reinforcement learning in the laws of physics and the constraints of real engineering. These are exactly the kinds of challenges - and assets - that make post-training and alignment research here genuinely distinctive.

We publish at NeurIPS, ICML, ICLR, CVPR, and SIGGRAPH. We collaborate with leading academic and industry labs. And we have a direct line from research advances to product impact at scale. This is not a role where research sits behind a wall from engineering - you will see your work matter.

Responsibilities

  • Post-training for model development - from RLHF and preference optimization to agentic systems and long-horizon reasoning

  • Develop novel algorithms that improve model reliability, controllability, and alignment

  • Make principled architectural decisions about when to address challenges at the pre-training, post-training, or system level

  • Design and run experiments that shape model behavior, robustness, and reasoning quality

  • Partner with infrastructure teams to build scalable, reproducible post-training workflows

  • Contribute to publications, patents, and Autodesk's external research visibility

  • Design evaluation frameworks for long-horizon reasoning, tool use, agentic behavior, safety, and real-world workflow completion

  • Lead rigorous model analysis and interpretability efforts

  • Drive human-in-the-loop evaluation with high annotation quality and sound scientific methodology

  • Establish model readiness criteria and provide go/no-go recommendations for releases

  • Communicate technical risks, limitations, and trade-offs clearly to leadership

Minimum Requirements

  • Deep hands-on expertise in reinforcement learning for foundation models, and fluency with post-training methods (RLHF, RLAIF, DPO, PPO, or adjacent approaches)

  • Proven experience leading or mentoring technical research teams - whether in an academic lab, AI research organization, or industry setting

  • Strong intuition for model behavior, alignment challenges, and post-training trade-offs

  • Experience designing evaluation systems and thinking rigorously about what it means for a model to be ready

  • Ability to communicate complex technical trade-offs clearly to both technical and non-technical audiences

  • A PhD or equivalent depth of industry research experience in ML, RL, AI, or a related field

  • Experience at a frontier model lab or advanced applied AI organization

  • A strong publication record at leading ML or AI venues

  • Background in alignment research, preference learning, or agentic AI

  • Experience deploying or supporting production AI systems

  • Familiarity with large-scale training infrastructure and compute trade-offs
