About Mecka AI
Mecka AI is building the data infrastructure layer for robotics and embodied AI.
We partner with leading AI labs and robotics companies to deliver high-quality, real-world datasets used to train, evaluate, and deploy robotic systems. Our work sits directly between research, data, and real-world execution — where model performance is dictated by data quality.
Our Mission
Robotics will become the largest industry in human history — larger than anything that has come before it. As intelligent machines move into the physical world, they will dramatically expand global GDP, raise the material standard of living for everyone, and ultimately help make humanity a multiplanetary civilization. None of that happens without one thing: enormous amounts of high-quality, real-world data.
Mecka AI builds that foundation. We are the data infrastructure layer for robotics and embodied AI — the substrate that teaches machines to perceive, reason, and act in reality. Get this right, and we accelerate the most important technological transition of our time.
Our Culture
Excellence as the baseline. We hold an extremely high bar and expect the best work of your career. Mediocrity isn't interesting to us.
Highly technical. We reason from first principles, not by analogy. The best argument wins — regardless of title or tenure.
Truth-seeking. We are relentlessly honest with ourselves and each other. We chase reality — measured, not assumed — and kill our own bad ideas fast.
Maniacal urgency. The work matters and the clock is real. We move fast, ship, measure, and iterate.
Extreme ownership. You own outcomes end-to-end — no hand-offs, no excuses, no waiting for permission.
Hardcore. This is a high-intensity environment for people who want to do the defining work of their lives.
The Role
We are looking for a Research Scientist, Video Understanding to own Mecka’s video understanding agenda end-to-end: train large-scale video representation and video-language models on our egocentric + stereo corpus, and turn the resulting checkpoints into production signals the rest of the stack ships on.
This role is focused on large model training, video encoders, video-language models, VLMs/VLAs, and temporal representation learning on real-world robotics data.
What You’ll Work On
Large-Scale Training & Architecture
Own model architecture and training strategy across Mecka’s task families (manipulation, locomotion, daily activity, long-horizon behavior).
Run self-supervised and multimodal pretraining (VideoMAE / VJEPA / VideoPrism / InternVideo-class) with rigorous evals and clean ablations.
Video-Language & Multimodal Modeling
Train and fine-tune video encoders and video-language models (temporal transformers, joint-embedding models, contrastive objectives, masked modeling, instruction/video alignment).
Incorporate useful priors (pose, depth, camera motion, optical flow) when it improves representation quality.
Research → Production Signals
Turn checkpoints into usable artifacts: embeddings and model outputs that downstream systems can reliably consume (retrieval, labeling, QA, analytics).
Build a disciplined training + eval workflow with regression tracking and reproducible runs.
Who You Are
Required Background
Deep experience training large models in PyTorch (or equivalent), including multi-GPU or distributed training.
Strong understanding of modern video representation learning and/or multimodal modeling.
Ability to run rigorous experiments and communicate results clearly.
Warning: Research Scientist positions require hyper-specific expertise. Please limit your applications to one research role. Applying to multiple Research Scientist positions suggests a lack of focus and may result in the rejection of all submissions. You may, however, apply to other non-research roles alongside your research application.
Strong Signals:
Experience with video VLMs / VLA-adjacent systems (VideoCLIP, InstructBLIP-Video, LLaVA-Video-class).
Experience with egocentric / embodied datasets (Ego4D, EgoExo4D, EPIC-Kitchens, Something-Something).
Strong software engineering discipline: you write research code that can be shipped.
Why This Role
Work on a domain — egocentric embodied video — where data is scarce everywhere except here.
Own a research agenda that directly feeds production systems and product outcomes.
