You will work at the intersection of deep learning, 3D computer vision, and geometric estimation, developing learned components for vision-based navigation. You will own the model development pipeline—from selecting tools, defining annotation needs, and cleaning data through training, evaluation, integration support, and deployment recommendations. Hands-on experience with Deep Learning and 3D computer vision and geometry is required; prior experience specifically in vision-based navigation is optional. What you'll do: • Develop and evaluate models for tasks such as feature detection and matching, visual correspondence, depth estimation, relative pose estimation, and image-to-map localization. • Combine learned visual representations with geometric methods to improve localization accuracy, robustness, and recovery under challenging conditions. • Own data preparation and supervision strategies, including dataset curation, annotation requirements, labeling tools, automated quality checks, and coverage analysis. • Select and integrate deep learning tools and build reproducible training workflows, including experiment tracking, configuration management, and dataset and model versioning. • Design evaluations that measure both model performance and downstream localization outcomes across changes in lighting, viewpoint, altitude, terrain, weather, and sensor characteristics. • Analyze failures and use controlled experiments to prioritize improvements to data, supervision, models, and integration. • Partner with state estimation engineers to integrate learned measurements and confidence estimates into VIO and terrain-relative navigation systems. • Profile models against onboard compute, memory, and latency constraints, and work with deployment engineers on optimization and runtime validation. • Deliver tested, documented components and interfaces for Hivemind SDK, collaborating with software, systems, and flight test teams. Required qualifications: • M.S. in Aerospace Engineering, Electrical Engineering, Robotics, Computer Science, or a related field; minimum 4+ years of related professional work experience with an M.S. degree, or 2+ years with a Ph.D. • Hands-on experience designing, training, debugging, and evaluating models using PyTorch or an equivalent framework, including architecture selection, loss design, optimization, and augmentation that preserves geometric consistency. • Strong foundations in camera models, coordinate transformations, projective geometry, and multi-view geometry, with practical experience in one or more fields: vision-based navigation, visual geolocation, Structure from Motion (SfM), SLAM, 3D reconstruction, depth estimation or similar fields. Expertise in every area is not required. • Strong Python skills and experience writing maintainable, reusable software. Demonstrated ability to take a computer vision capability from problem definition and raw data through training, evaluation, and integration readiness. • Experience building pipelines for sensor data ingestion, cleaning, filtering, deduplication, and dataset versioning. • Ability to select and integrate development tools and build reproducible training workflows, including configuration management, experiment tracking, checkpointing, and GPU performance troubleshooting. • Experience designing benchmarks, preventing data leakage across related sequences or locations, analyzing performance across operating conditions, and connecting model metrics to downstream geometric or localization accuracy. • Ability to profile inference latency and memory use, document model interfaces and preprocessing, assess accuracy–compute tradeoffs, and advise deployment engineers on export, precision, and runtime optimization. • Ability to communicate assumptions, experimental findings, and design tradeoffs clearly and translate research into working software. Preferred qualifications: • Experience with aerial imagery, geospatial data, elevation maps, or matching observations across viewpoint, lighting, season, or sensor modality • Experience with model export, quantization, TensorRT, ONNX, or deployment on embedded compute platforms. • Experience validating perception or robotics systems on physical platforms. • Relevant publications, open-source contributions, or demonstrated delivery of production computer vision systems, familiar with methods including: • feature correlation, correlation or cost volumes, and matching methods for correspondence, stereo, optical flow, or localization. • learning priors over scene geometry, depth, motion, or appearance to improve estimation under sparse, ambiguous, or degraded observations. • applying diffusion models or flow matching to computer vision, geometric inference, or conditional generation. • Experience in aerospace and / or defense industry. You do not need every nice-to-have to succeed in this role. We welcome engineers with strong Deep Learning and 3D vision foundations who are excited to develop expertise in state estimation and navigation to apply. #LI-KC3 #LD Full-time regular employee offer package: Pay within range listed + Bonus + Benefits + Equity   Temporary employee offer package: Pay within range listed above + temporary benefits package (applicable after 60 days of employment)   Salary compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, licenses and certifications, and specific work location.
