Senior World Modeling & Simulation Engineer

Applied Intuition; Washington; On-site; USD 150,000 - 200,000; Full time

Job summary

Applied Intuition is seeking a Senior Software Engineer to architect the world representation layer of its Acuity autonomy stack. You will define 4D spatial abstractions and ECS-based structures for large-scale multi-agent environments.

The role requires expert C++20 skills, deep computational geometry knowledge, and a focus on low-latency real-time performance. Collaboration across sensor, planning, and simulation teams is essential.

Qualifications

• 7+ years of professional software engineering experience, with deep expertise 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 — including managing dynamic object state, spatial indexing, and real-time updates
• Strong background in computational geometry: coordinate transformations, spatial data structures (BVH, octrees, k‑d trees), geometric algorithms, 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 agentic coding tools (Cursor, Claude Code, GitHub Copilot) and AI-assisted development workflows

Responsibilities

• Architect World & Scene Representation Systems: Design and implement core spatial data structures, including ECS frameworks, spatial indexing, occupancy representations, 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 spatial queries
• Drive Performance to the Metal: Write highly optimized C++20 with low latency, cache-friendly and memory-conscious design; profile hot paths and minimize allocations
• Lead Technical Strategy & Integration: Drive architectural decisions and design clean APIs for cross-domain integration across autonomy stacks
• Collaborate & Mentor: Act as technical anchor across teams with sensor, planning, and simulation engineers to ensure the scene layer meets needs
