Summary
👤
Senior🎓
Top SchoolSébastien Mamessier is a Senior Staff Engineer with 14 years of international experience building safe, robust AI and large-scale software platforms across self-driving, aviation, fintech and e-commerce. He blends deep mathematical and robotics training (PhD pending, MS Aerospace, pure mathematics background) with hands-on leadership—driving deterministic simulation, uncertainty-aware autonomy, reproducible DevOps (Bazel/GCP/GitLabCI) and data/ML platforms from prototype to production. As a former engineering lead at Uber ATG/Elevate and tech lead at Airbus, he has shipped low-latency perception and motion-planning systems as well as VR-enabled human factors simulators. More recently he co-founded Rectangle and now leads engineering at Glydways, where he continues to scale interdisciplinary teams and probabilistic decision-making systems. Colleagues know him for combining rigorous academic instincts with pragmatic engineering culture-building and an unusual breadth spanning low-level performance optimization to product-facing data science.
