Software Engineer - 4D World & Simulation Engines

Applied Intuition; Ann Arbor (MI); Hybrid; USD 120,000 - 190,000; Full time

Job summary

Applied Intuition in the United States seeks an engineer to design and develop the world representation layer for the Axion simulation stack. You will shape 4D spatial abstractions, ECS, and high-performance data structures used by multi-agent simulations across air, ground and maritime domains.

The role sits at the intersection of computational geometry, real-time world modeling, and large-scale simulation, requiring deep C++20 expertise, optimization, and integration with sensor fusion and

Qualifications

• 2+ years of professional software engineering experience in spatial systems, world modeling, or simulation environments.
• Expert-level C++ skills (C++20 or later), including template metaprogramming, move semantics, SIMD, and performance optimization at the systems level
• Hands-on experience building world or scene representations—from a game engine, sim platform, or autonomous system
• Strong background in computational geometry: coordinate transformations, spatial data structures (BVH, octrees, k-d trees) and collision/proximity systems
• Deep intuition for low-latency, high-throughput software design in real-time environments
• Strong proficiency in Python and shell scripting for tooling and automation
• Experience with AI-assisted development workflows (Cursor, Claude Code, GitHub Copilot)

Responsibilities

• Develop World & Scene Representation Systems: Design core spatial data structures, including ECS frameworks, spatial indexing, and 4D object management for large-scale multi-agent environments.
• Own Mapping & Geometry Pipelines: Build and optimize geometry and world-state systems between raw sensor data and path planning, including coordinate frame management and environment abstractions.
• Drive Performance to the Metal: Write highly optimized C++ (C++20+), profile hot paths, reduce allocations, and ensure real-time performance of spatial systems.
• Technical Strategy & Integration: Drive architectural decisions and design clean APIs enabling cross-domain integration across autonomy stacks.
