About The Position

Mecka AI is building the data infrastructure layer for robotics and embodied AI. We design and operate global systems for data labeling, data capture, and hardware-enabled workflows used by leading AI and robotics teams. These products are used daily by operators, contributors, country managers, and customers across multiple countries. Design quality matters.

You’ll work closely with engineers, operators, and founders, shipping quickly and iterating in real production environments. This role is ideal for someone who thrives in early-stage startups and balances taste, speed, and practicality.
