Key skills for this role
The Johns Hopkins Center for Bioengineering Innovation & Design (CBID) in the Department of Biomedical Engineering is seeking an Assistant Research Engineer to lead computer vision and AI development for the VectorCam platform. VectorCam is an AI-enabled mobile imaging system designed to allow community health workers to identify mosquito species in real time, enabling faster vector surveillance and improved malaria control strategies. This role will serve as the technical lead for computer vision and image analysis within the project, responsible for designing and iterating on machine learning architectures, managing training pipelines and datasets, and optimizing models for deployment across edge and cloud environments. The successful candidate will work at the intersection of computer vision, edge AI deployment, mobile imaging systems, and global health field implementation. The role requires someone who is highly experimental and curious, constantly exploring new model architectures and approaches while pushing the performance and reliability of the AI system. The ideal candidate will also demonstrate strong attention to detail in data management and data science practices, and be able to clearly articulate the probability, statistics, and evaluation methods used when defending model design choices and performance claims.

Technical Focus Areas Computer Vision and Model Development: Design and train deep learning models for insect classification and morphological recognition. Experiment with architectures such as EfficientNet, YOLO, Vision Transformers, and other modern computer vision models to determine optimal approaches for the application. Develop strategies for handling limited datasets, noisy data, and challenging real-world image conditions.
Model Optimization for Edge Deployment: Optimize models for deployment on smartphones using frameworks such as TensorFlow Lite, PyTorch Mobile, or ONNX. Investigate quantization, pruning, and other model optimization techniques to ensure efficient inference on resource-constrained devices. Ensure models perform consistently across different smartphone cameras and hardware configurations.
AI Data Pipeline and Dataset Management: Develop systems for dataset versioning, experiment tracking, and model reproducibility. Ensure that training, validation, and testing datasets are well organized, auditable, and traceable. Maintain clear documentation of dataset lineage and experiment configurations. Build workflows that support continuous model retraining as new field data becomes available.
System Architecture for AI Deployment: Design the architecture for managing model updates, versioning, and deployment across edge devices and cloud platforms. Develop strategies for monitoring model performance and maintaining reliability across large-scale field deployments.
Project Impact VectorCam aims to transform how mosquito surveillance is conducted in malaria-endemic regions by enabling rapid and accurate species identification directly in the field. By improving the speed and accessibility of entomological surveillance, this technology has the potential to strengthen malaria control programs and support more targeted vector control interventions. This role offers the opportunity to work on a globally impactful technology while solving challenging problems at the intersection of computer vision, edge AI, and public health innovation.
