#49916 LiDAR 3D Annotation & Data Labeling Specialist

At Mindy Support, we are a global leader in data annotation and business process outsourcing, powering cutting-edge AI and machine learning solutions for Fortune 500 companies and fast-growing tech innovators. We foster a collaborative, remote-first environment where detail-oriented professionals can build long-term tech-adjacent careers.

We are currently looking for LiDAR 3D Annotation & Data Labeling Specialists to join our team on a long-term project focused on 3D LiDAR cuboid annotation and spatial segmentation. High-performing contributors will gain priority access to advanced, higher-paying autonomous vehicle and spatial AI projects.

What You’ll Do

3D Point Cloud Bounding Box Annotation: Fit tight 3D cuboids around objects (vehicles, pedestrians, cyclists, static structures) across frame sequences with high spatial accuracy.

3D Semantic Segmentation: Label individual points within dense point clouds to define complex environmental geometry with zero gaps or overlaps.

Multi-Sensor QA & Verification: Review, refine, and audit AI-generated 3D bounding boxes and sensor fusion alignments (LiDAR overlaid with 2D camera feeds).

Object Tracking & Trajectory Consistency: Track dynamic objects across multi-frame LiDAR scenes, ensuring accurate pitch, roll, yaw, and heading vector consistency.

What We’re Looking For

Experience: Minimum 6+ months of hands-on experience in 3D LiDAR point cloud annotation, 3D segmentation, or multi-sensor data labeling.

Tool Proficiency: Proven expertise using 3D spatial software such as Segments.ai, BasicAI, Cognic, Scale AI, CVAT, or equivalent platforms.

Quality Standards: Ability to maintain a 95%+ accuracy rate, strictly adhering to tight cuboid boundary rules, point-count density thresholds, and occlusion handling.

Precision: Ability to segment visually verifiable 3D spatial geometry objectively without unverified assumptions.

Workflow Efficiency: Skilled in using software shortcuts and hotkeys to execute 3D sequence workflows while running background screen-recording tools.

Professional Mindset: Reliable, detail-oriented, and comfortable working in a structured, quality-driven environment.

Onboarding & Certification Process

Training & Practice: Review spatial guidelines, master hotkeys, and practice on sample 3D point cloud datasets.

Benchmark Test: Annotate 3–5 3D LiDAR tasks within quality and speed benchmarks.

Paid Certification: Complete a ~1-hour onboarding process (paid upon entry to production tasks).

Production: Access ongoing paid project batches immediately upon passing certification.

Project & Payment Details

Work Schedule: 25–40 hours per week (long-term contract, though occasional short idle times may occur).

Payment Methods: PayPal, Bank Transfer, or Payoneer.

Equipment Requirements: Stable internet connection, a capable PC/laptop for 3D rendering, and screen-recording software compatibility.
