Computer Vision Engineer, 3D

Mecka; New York (NY); On-site; USD 141,000 - 162,000; Full time

Job summary

Mecka is seeking a strong, coding-heavy computer vision engineer to own the classical stack. You will manage 3D geometry, temporal filtering, and inverse kinematics to transform model outputs into clean, calibrated spatial data for delivery.

You’ll partner closely with research teams, understand the models, but not train them. Your focus will scale to the entire pipeline, bridging geometry, filtering, and data quality across projects.

Qualifications

• 5+ years of professional software engineering and computer vision.
• Strong production Python; C++ is a plus.
• Solid multi-view geometry: triangulation, PnP, camera calibration, reprojection.
• Temporal filtering and signal processing: low-pass and Kalman-family filters.
• Inverse kinematics and bone-length constraints on articulated structures.
• Some ML familiarity with pose/mesh outputs and failure modes.
• Data-quality mindset; comfortable with noisy real-world data and QA.

Responsibilities

• Own the classical 3D geometry that places reconstructions in space: multi-view geometry, triangulation, PnP, calibration, undistortion, reprojection.
• Design and tune temporal filters to remove jitter without losing real motion and consistency.
• Run inverse Kinematics and enforce physical constraints to keep reconstructed skeletons valid and clean.
• Turn model output into delivered data, including per-frame results, reports, and QA metrics for scale.
• Build visualizers and dashboards to inspect trajectories and failure cases.
• Be the go-to engineer for classical computer-vision problems across the pipeline.
• Provide support for classical CV challenges across the pipeline as they arise.

About Mecka AI

About Mecka AI

Mecka AI is building the data infrastructure layer for robotics and embodied AI.

We design and operate global systems for data capture, data labeling, and hardware-enabled workflows used by leading AI labs and robotics companies to train and validate humanoid and embodied AI systems.

We work closely with frontier robotics teams to bridge real-world data, simulation, learning-based systems, and deployed hardware.

The role

We're looking for a strong, coding-heavy computer vision engineer to own the classical side of our stack. Our models produce raw per-frame predictions; you own the traditional computer vision, temporal filtering, and inverse kinematics — backed by excellent software engineering — that turn those into clean, rigid, smooth, correctly-calibrated spatial data we can deliver.

You’ll partner closely with our research teams — you need to understand the models, but you won’t be training them.

Your immediate focus is our 3D hands pipeline, where this work is needed most today. From there you'll be our classical-CV specialist across the organization, brought in wherever geometry, filtering, or pipeline problems come up.

What You'll Do

• Own the classical 3D geometry that places reconstructions correctly in space: multi-view geometry, triangulation, PnP, camera calibration, undistortion, and reprojection.
• Design and tune temporal filters (low-pass, Kalman-family, interpolation) that remove jitter without losing real motion.
• Run inverse kinematics and enforce physical constraints such as bone-length rigidity so reconstructed skeletons stay valid. Build the checks that keep bad frames out of delivery.
• Turn model output into clean delivered data, including per-frame results, reports, and the QA metrics that gate delivery, and keep the pipeline running at scale.
• Build visualizers and dashboards to inspect trajectories, overlays, and failure cases.
• Be the go-to engineer for classical computer-vision problems across the pipeline as they come up.
• go-to for classical computer-vision problems elsewhere in the pipeline as they come up.

What You Bring

Must-have:

• 5+ years of professional experience in software engineering and computer vision.
• Strong software engineering. This is a coding-heavy role: clean, efficient, production Python (C++ is a plus).
• Solid multi-view geometry: triangulation, PnP, camera calibration, reprojection, and coordinate transforms.
• Temporal filtering and signal processing: low-pass and Kalman-family filters, interpolation, and a feel for the trade-off between smoothness and fidelity.
• Inverse kinematics and rigid-body or bone-length constraints on articulated structures.
• Enough ML to work with deep models such as pose and mesh regressors, including their outputs and failure modes, without training them yourself.
• A data-quality mindset: comfortable with noisy real-world data and building QA that catches problems before customers do.

Nice-to-have:

• Human pose or mesh reconstruction (hand or body), including keypoint and mesh pipelines.
• Depth in Bayesian filtering or state estimation; experience with optimization frameworks such as Ceres or GTSAM.
• Building CV tooling such as trajectory visualizers and overlay or QA dashboards.
• Stereo, multi-view, or ego-exo capture experience.
• Light temporal ML, such as small networks for smoothing or gap-filling.

Inclusive Hiring at Mecka

We are committed to creating an inclusive and supportive candidate experience. Should you require any accommodation whatsoever during the interview process, please inform us without any hesitation. Mecka is dedicated to ensuring equal treatment and opportunity in all phases of recruitment, selection, and employment, in compliance with employment law.
