Data Operations - Annotation
Job Description
Mind Robotics is building intelligent robotics for industrial deployment. We believe the fastest path to broadly capable robots is through clearly defined, high-impact environments. We are starting where the need is most acute and the environment is most exacting: the factory floor.
Role Summary
This role is critical to transforming raw collected data into structured, high-quality, and labeled datasets for training our models. You will own the end-to-end annotation program, including defining guidelines, managing quality standards, operating tooling, and ensuring data integrity as volume scales.
Key Responsibilities
Annotation Program Design & Tooling
Define and maintain annotation guidelines and sub-task ontology in partnership with the ML team.
Manage annotation tooling, including access provisioning, queue management, and the export pipeline to MCAP.
Prioritize the annotation queue to align with the ML team’s data requests.
Explore and integrate annotation platforms (such as Encord) to support customisation and flexibility during the experimentation phase.
Quality Assurance & Data Fidelity
Develop and maintain the automated quality classification pipeline (Stage 4), including assessing lighting quality and detecting sync errors, frame drops, and hand visibility.
Monitor Inter-Annotator Agreement (IAA) weekly and run calibration sessions for annotators who fall below the required threshold.
Build model-assisted annotation pre-labeling, using a lightweight action segmentation model to pre-populate sub-task boundaries for human correction.
Team Management & Throughput
Hire, onboard, train, and manage the data annotators.
Establish and track key performance indicators (KPIs) for the annotation program, including reporting weekly on episodes annotated, queue depth, IAA score distribution, and rejection rate.
Monitor the output of the annotation engine to ensure data is useful for training, focusing on "Quality over Quantity".
Qualifications
Background: Specialist with 2+ years of experience managing annotation or data labeling teams, ideally with experience in video annotation.
Technical Expertise: Familiarity with annotation platforms (e.g., CVAT, Label Studio, or similar) and a strong understanding of computer vision components for video processing.
Strategic Mindset: Ability to treat data collection as a product, balancing immediate operational needs with long-term quality and scaling goals.
Experience: Proven track record in defining and maintaining structured annotation guidelines and sub-task ontologies.
