Join Us in Making Cities Greener and More Sustainable

Are you passionate about using technology to combat climate change and enhance urban living? At greehill, we’re looking for an Algorithm Engineer - Sensor Data Processing to help us shape the future of sustainable cities. Join our mission to make urban environments around the world greener, healthier, and more resilient.

Who We Are

greehill is a global leader in nature-based smart-city solutions, driven by a passion for sustainability and innovation. We harness advanced technologies like remote sensing and machine learning to transform urban green spaces. Our cloud-based platform empowers cities to improve citizen well-being while reducing operational costs, using data from LiDAR scanners and camera systems to create digital twins of urban trees. With offices in Budapest, Berlin, Singapore, San Francisco, and Paris, we’re driving sustainability on an international scale.

As an Algorithm Engineer - Sensor Data Processing at greehill, you will play a pivotal role in developing innovative algorithms to extract valuable insights from diverse sensor data sources, including LiDAR, images, and satellite imagery. Your work will directly contribute to creating accurate digital representations of urban trees and green spaces, supporting our mission to enhance urban sustainability.

Key Responsibilities

• Design and implement algorithms to process and analyze sensor data from sources like LiDAR, images, and satellite imagery, extracting meaningful information about urban trees and environments.
• Create algorithms to transform sensor data into actionable insights, such as reconstructing 3D models, segmenting spatial data, or detecting environmental features.
• Develop techniques for preprocessing raw sensor data, including noise filtering, sampling, and quantization, to ensure data quality and usability.
• Optimize algorithms for performance and scalability to handle large, complex datasets efficiently.
• Integrate data from multiple sensor types to enhance the accuracy and detail of digital representations.
• Contribute to the continuous improvement of our data processing tools, methods, and pipelines.
• Stay informed about advancements in sensor data processing, computer vision, and geospatial analysis to bring fresh ideas to the team.

Qualifications

• Education: Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Robotics, or a related field.
• Programming Skills: Strong proficiency in Python, with experience using libraries such as numpy, pandas, open3d, and opencv for data processing and analysis.
• Algorithmic Expertise: Solid foundation in algorithms and data structures, with a focus on solving complex, real-world problems.
• Sensor Data Experience: Practical knowledge of processing sensor data (e.g., LiDAR point clouds, image data).
• Computer Vision: Familiarity with computer vision techniques, such as feature detection, segmentation, or 3D reconstruction, applied to real-world data.
• Critical Thinking: Strong problem-solving skills, attention to detail, and a creative approach to tackling technical challenges.
• Teamwork: Ability to collaborate effectively with multidisciplinary teams, including engineers and machine learning specialists.
• Communication: Excellent skills in conveying technical concepts clearly and concisely.

Preferred Qualifications

• Experience with geospatial data processing and tools (e.g., GDAL, rasterio) for handling satellite imagery or remote sensing data.
• Knowledge of mapping techniques, such as structure from motion or SLAM (Simultaneous Localization and Mapping), for spatial data analysis.
• Familiarity with clustering methods (e.g., HDBSCAN, DBSCAN) or similar techniques for segmenting and analyzing sensor data.
• Understanding of data structures like graphs and trees for representing complex spatial information.
• Exposure to machine learning tools (e.g., sklearn, pytorch) is a plus, though not the focus of this role.
• Experience optimizing algorithms for computational efficiency and scalability.
