Senior Offline Mapping Engineer

Senior Offline Mapping Engineer owning accuracy and robustness of offline SfM, multi-view stereo, and 3D reconstruction pipelines. Integrates classical geometry with deep learning (learned matching, depth priors) for challenging real-world environments like textureless and reflective scenes. Requires advanced degree, production 3D vision experience, and hybrid work in Columbia, MD.

About the job

Offline Mapping & Reconstruction

  • Develop and advance our offline mapping and reconstruction pipeline, driving accuracy and robustness across the hardest capture scenarios — textureless walls, highly reflective surfaces, featureless geometry, and large-scale scenes.
  • Reduce pose estimation failures and increase geometric accuracy in environments where classical methods degrade, using a combination of improved estimation and learned components.
  • Design and integrate deep learning methods (learned feature matching, monocular depth priors, learned outlier rejection) alongside classical SfM and MVS components to close the last 10% of reconstruction quality.
  • Improve calibration pipelines, bundle adjustment robustness, and dense reconstruction fidelity in offline processing contexts where throughput matters but hard real-time does not.

Research Integration & Evaluation

  • Build and maintain evaluation methodology grounded in real-world captures — covering feature-rich, textureless, and reflective environments — not synthetic benchmarks alone.
  • Stay current with the deep learning and 3D vision literature, applying good judgment about which methods are production-viable and which are benchmark artifacts.
  • Collaborate closely with the SLAM and real-time mapping team to share components and ensure offline improvements feed back into the broader reconstruction platform.

Must-Have Qualifications

  • Master’s, or PhD in Computer Science, Computer Vision, Robotics, or a related field — or equivalent demonstrated experience. This is a Senior-to-Staff level role.
  • Significant hands-on experience building or substantially improving an offline SfM, multi-view stereo, or dense reconstruction system in production — not just research prototypes.
  • Strong C++ and Python.
  • Deep working knowledge of multiview geometry, bundle adjustment, nonlinear estimation, and — critically — the practical failure modes of each.
  • Real experience with sensor calibration on real hardware.
  • Hands-on ability to design, train, and integrate deep learning components (learned matching, depth estimation, feature extraction) into a classical reconstruction pipeline using PyTorch or equivalent.
  • Willingness to work on-site in Columbia, MD, in a hybrid capacity.
  • Meet Quidient, customer, and government security requirements, which may include, but are not limited to a background check, citizenship verification, and Criminal Justice Information Services verification.

Nice-to-Have Qualifications

  • Experience in fast-paced or startup environments.
  • Prior work on reconstruction of textureless, reflective, or geometrically challenging environments.
  • Published or shipped work combining learned and classical methods in 3D vision pipelines.
  • Expertise in neural scene representations (NeRF, Gaussian Splatting, or similar).
  • Experience with large-scale numerical optimization.
  • Contributor to open-source SfM, MVS, or 3D reconstruction projects (COLMAP, OpenMVS, or similar).
  • Track record of shipping mapping or reconstruction systems at production scale.

Compensation & Benefits

Salary Range: $175,000 - $230,000
Annual bonus and equity as appropriate.

Benefits:

  • Health insurance
  • HSA
  • 401(k) with company match
