Software Engineer - Simulation, Game Engine & World Systems (Autonomy)

About the role

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.

Responsibilities

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

Requirements

• 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.
• Strong proficiency in Python and shell scripting for tooling and automation.
• Expertise with the Linux/Docker/C++ toolchains (including build systems like Nix and Bazel).
• Experience with temporal reasoning systems and 4D scene representation (space + time).
• Background in game development, simulation, or virtual environments.
• Understanding of autonomous systems or robotics software architectures.

Qualifications

• Must be a U.S. Citizen.
• Must hold or be eligible to obtain and maintain a U.S. security clearance.

Skills

• Agentic coding tools (Cursor, Claude Code, GitHub Copilot) and AI-assisted development workflows.

Benefits

• Base salary is a single component of the total compensation package, which may also include equity in the form of options and/or restricted stock units.
• Comprehensive health, dental, vision, life and disability insurance coverage.
• 401k retirement benefits with employer match.
• Learning and wellness stipends.
• Paid time off.

Pay

• Compensation at Applied Intuition for eligible roles includes base salary, equity, and benefits.
• Pay ranges reflect the minimum and maximum intended target base salary for new hire salaries for the position.

Schedule

• This is an in-office position, with an expectation of working from the office 5 days a week.
• 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 may be allowed.

Security Requirements

• Must be a U.S. Citizen.
• Must hold or be eligible to obtain and maintain a U.S. security clearance.
