Roblox Senior Software Engineer on the Geometry team responsible for developing algorithms for real-time 3D content creation and editing. Leads complex projects and mentors junior engineers while solving computational geometry problems.
Responsibilities
Own End-to-End Development: Lead complex, team-level projects through the full development lifecycle, from research and prototyping to production deployment and maintenance.
Architect Robust Solutions: Develop efficient algorithms for geometry processing (e.g., convex decomposition, mesh partitioning, boolean operations) that support real-time simulation, collision detection, and performance requirements across all platforms.
Mentor and Lead: Provide technical guidance and mentorship to junior engineers, fostering a culture of high standards, code quality, and collaborative architectural discussions.
Solve Computational Problems: Tackle discrete math and computational geometry challenges, applying linear algebra, numerical solvers, and advanced data structures to deliver robust features.
Think Systemically: Anticipate downstream impacts of your technical decisions, ensuring solutions are scalable, maintainable, and aligned with the long-term vision of the Geometry and Engine teams.
Collaborate Cross-Functionally: Work closely with other teams (Graphics, Physics, Avatar) to ensure cohesive integration of geometry components into the broader Roblox experience.
