Senior Software Engineer, World Modeling & Simulation

Applied Intuition Applied Intuition · Robotics · Washington, DC · Government

Senior Software Engineer to architect the world representation layer at the heart of Applied Intuition's Acuity autonomy stack. This role involves building spatial worlds for games, simulations, or autonomous systems, defining how environments are structured, queried, and updated at high frequency. It sits at the intersection of computational geometry, real-time world modeling, and large-scale simulation, owning foundational scene and mapping systems for downstream sensor fusion and path planning.

What you'd actually do

  1. Architect World & Scene Representation Systems: Design and implement core spatial data structures, including Entity Component System frameworks, spatial indexing, occupancy representations, and 4D object management for large-scale multi-agent environments.
  2. Own Mapping & Geometry Pipelines: Build and optimize the computational geometry and world-state systems that sit between raw sensor data and the path planning stack — including coordinate frame management, spatial queries, and environment abstraction layers.
  3. Drive Performance to the Metal: Write highly optimized C++ (C++20) with a focus on low-latency, cache-efficient, and memory-conscious design. You should be comfortable profiling hot paths, eliminating allocations, and squeezing real-time performance out of complex spatial systems.
  4. Lead Technical Strategy & Integration: Drive architectural decisions and design clean APIs that enable cross-domain integration across air, ground, and maritime autonomy stacks.
  5. Collaborate & Mentor: Act as a technical anchor across teams — engaging proactively with sensor, planning, and simulation engineers to ensure the scene layer meets the needs of the full autonomy stack.
