Senior Software Engineer, Game Engine & World Systems

Senior Software Engineer architecting core world representation, scene, and mapping systems (Entity Component Systems, 4D spatial data structures, computational geometry) at the heart of an autonomy stack for multi-domain (air/ground/maritime) simulation and robotics. Requires 7+ years experience, expert C++20 performance engineering, and real-time spatial systems background from games, sims or AV.

About the role

Responsibilities

  • 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.
  • 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. Profile hot paths, eliminate allocations, and squeeze real-time performance out of complex spatial systems.
  • Lead Technical Strategy & Integration: Drive architectural decisions and design clean APIs that enable cross-domain integration across air, ground, and maritime autonomy stacks.
  • 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.

Requirements

  • 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.
  • Must be a U.S. Citizen.
  • Must hold or be eligible to obtain and maintain a U.S. security clearance.
  • Must be willing to travel as projects require; average travel varies, but can be up to once a month for up to 1 week (~20%).

Nice-to-Haves

  • Expertise with the Linux/Docker/C++ toolchains (including build systems like Nix and Bazel) and cross-compilation.
  • Experience with temporal reasoning systems and 4D scene representation (space + time).
  • Background in game development, simulation, or virtual environments.
  • Knowledge of physics engines and collision detection systems.
  • Understanding of autonomous systems or robotics software architectures.
