Assistant Research Engineer - Full - stack Web & Mobile Development - #faculty

Assistant Research Engineer

The Johns Hopkins Whiting School of Engineering and the Center for Bioengineering Innovation and Design are seeking a motivated Assistant Research Engineer to join our dynamic team. The Assistant Research Engineer will support the research, development, and deployment of the VectorCam platform, an AI-enabled vector surveillance system funded by the Gates Foundation. Following the successful completion of a one-year randomized controlled trial, VectorCam is now scaling across multiple countries in Africa, Latin America, and Asia. The engineer will play a central role in expanding the VectorCam web application by designing new features, customizing workflows for country programs, and implementing feature flags that support rapid and reliable multi-country deployments. The role operates in a fast-paced Agile development environment and involves close collaboration with the Software Lead, global research partners, and the Johns Hopkins University team. The ideal candidate is a mission-driven software engineer who enjoys solving complex workflow problems, iterating quickly based on user feedback, and building dependable systems for real-world global health applications. While the primary focus is on the web application, there are opportunities to contribute across mobile development, backend services, and cloud infrastructure for candidates with relevant interest or experience. The successful candidate will take ownership of technical decisions and help scale VectorCam across Uganda, Kenya, Ghana, Colombia, and additional countries as national programs adopt the tool.

Why Work on our Team

VectorCam is at a pivotal moment. In only three years, our team has moved from early concept to a completed randomized controlled trial, Gates Foundation support, and multi-country implementation starting across Africa, Latin America, and India. We have proven that it is possible to replace decades-old manual surveillance with fast, digital, AI-enabled tools that give governments a clearer view of their disease landscape. You will join a team that believes global health systems can be redesigned through thoughtful engineering and strong partnerships. Many countries still rely on fragmented vector surveillance systems that slow decision-making and limit impact. We are building a new foundation that empowers frontline health workers, strengthens national programs, and creates a world where vector-borne diseases are fought with modern tools rather than outdated processes. Here, your work will matter immediately. A feature you design may change how a Ministry of Health allocates resources. A workflow you build may determine how fast an outbreak signal is detected. You will collaborate with government partners, researchers, and engineers who bring intense ambition and purpose to this mission. If you want to be part of a team that is rewriting what is possible in global public health, this is the right place to grow.
