Data Research Intern at Fujitsu Research of America
Location: Santa Clara, CA
The Space Data Frontier Research Center at Fujitsu focuses on combining research across multiple technical fields to address large-scale societal and industrial challenges. These challenges require new approaches that integrate artificial intelligence, sensing, modeling, optimization, and domain knowledge. Our goal is to develop evidence-based scientific tools that support decision-making, improve operational efficiency, and accelerate innovation across industries.
We are seeking exceptional research interns to join our Space Data Frontier Research Center Lab in Silicon Valley to work on next-generation maritime intelligence and port operations optimization. This project aims to develop an integrated decision-support framework that combines multi-source sensor fusion with port operations visibility and what-if planning. The framework will use heterogeneous data sources, including SAR imagery, optical imagery, AIS, RF signals, and port-area imagery, to track vessels, estimate operational states, diagnose congestion, and support improved port planning and control.
The internship duration is 3 months.
Job responsibilities
• Contribute to the development of multi-source maritime observation pipelines using SAR imagery, optical imagery, AIS data, RF detections, and related sensor metadata.
• Develop and test methods for detecting vessels, extracting motion cues, and estimating ship position, heading, speed, and confidence from heterogeneous sensing sources.
• Implement dynamic fusion algorithms for vessel state estimation under missing, noisy, delayed, or conflicting observations.
• Contribute to port operations visibility modules that detect vessels, cranes, berth activity, anchorage load, and yard activity indicators from satellite or other imagery.
• Develop models to estimate and forecast port operational state, including berth occupancy, anchorage count, yard congestion proxies, service-rate indicators, and anchorage waiting time.
• Develop simulation, optimization, or what-if planning methods to evaluate changes in berth assignment, service rates, resource availability, or other operating conditions.
• Publish research findings in scientific venues and present results in talks, conferences, workshops, and internal reviews.
Requirements
• Currently enrolled in a PhD program in a relevant area such as computer science, electrical engineering, mechanical engineering, artificial intelligence, robotics, remote sensing, applied mathematics, operations research, transportation systems, or a related engineering field.
• Strong programming skills in Python and experience with machine learning or scientific computing libraries such as PyTorch, JAX, NumPy, SciPy, or related tools.
• Demonstrated experience in one or more of the following areas: computer vision, remote sensing, geospatial analytics, sensor fusion, state estimation, probabilistic modeling, tracking, forecasting, optimization, or simulation.
• Familiarity with object detection, segmentation, or vision models such as YOLO, DETR, Mask R-CNN, Mask2Former, Vision Transformers, or related architectures is desirable.
• Experience with trajectory prediction, ETA forecasting, time-series modeling, uncertainty quantification, conformal prediction, Gaussian processes, recurrent networks or related methods is desirable.
• Experience with optimization or simulation methods, such as mixed-integer optimization, constraint programming, discrete-event simulation, queueing models, robust optimization, or simulation-based what-if analysis, is a plus.
• Excellent written and verbal communication skills, and the ability to collaborate across interdisciplinary teams.
Fujitsu is the largest IT company in Japan and among the largest in the world. Fujitsu's mission is to make the world more sustainable by building trust in society through innovation. Join us in shaping the future of maritime intelligence, port operations, and AI-driven decision support.
