Senior🎓
Top SchoolSean Zimmerman is a Senior Software Engineer with three years of professional experience building high-performance C++ systems for companies like MongoDB, Bloomberg, and Lockheed Martin. He specializes in infrastructure, observability, and backend/database engineering—contributing to the MongoDB codebase to fix replication error handling and improve stability. His physics background (3.95 GPA) shapes a cautious, analytical approach to complex systems and system-level debugging. At Bloomberg he led design and implementation of low-latency multicast networking and a centralized monitoring/configuration platform, while at Lockheed he combined Scrum leadership with rigorous testing and cross-platform C++ work. Tech-agnostic but pragmatic, he avoids front-end work and prefers roles focused on reliability, tooling, and observability. Based in Flemington, NJ, he is open to remote opportunities and brings a research-minded attention to detail from both clean-room and lab-based undergraduate projects.
