Software Engineer - Simulation, Game Engine & Systems; Autonomy

Engineer

Applied Intuition, Inc. is powering the future of physical AI. Founded in 2017 and now valued at $15 billion, the Silicon Valley company is creating the digital infrastructure needed to bring intelligence to every moving machine on the planet. Applied Intuition services the automotive, defense, trucking, construction, mining and agriculture industries in three core areas: tools and infrastructure, operating systems, and autonomy.

Eighteen of the top 20 global automakers, as well as the United States military and its allies, trust the company's solutions to deliver physical intelligence. Applied Intuition is headquartered in Sunnyvale, California, with offices in Washington, D.C.;
San Diego;
Ft. Walton Beach, Florida;
Ann Arbor, Michigan;
London;
Stuttgart;
Munich;
Stockholm;
Bangalore;
Seoul; and Tokyo.

We are an in-office company, and our expectation is that full-time employees primarily work from their Applied Intuition office 5 days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments.

This in-office expectation does not apply to contractor positions.

We're seeking a talented Engineer to work on a brand new initiative designing and developing the world representation layer at the heart of Applied Intuition's Axion simulation stack. If you've spent your time building the spatial worlds that games, simulations, or autonomous systems inhabit, defining how environments are structured, queried, and updated at high frequency this role was written for you.

This is deeply technical position sitting at the intersection of computational geometry, real-time world modeling, and large-scale simulation. You'll join a new team at the foundational scene and mapping systems that downstream sensor fusion and path planning both depend on: defining 4D spatial abstractions, Entity Component Systems, and the high-performance data structures that make multi-agent reasoning across air, ground, and maritime domains possible.

The ideal candidate has participated in a game engine, a robotics simulator, or an autonomous vehicle stack and knows what it takes to make those representations fast, accurate, and scalable under real operational constraints.

• Develop 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.
• 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.
• 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.
• Technical Strategy & Integration:
  Participate in driving architectural decisions and design clean APIs that enable cross-domain integration across air, ground, and maritime autonomy stacks.

• 2+ 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
