Senior Software Engineer, World Modeling & Simulation

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 optimize real-time performance 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 and hold or be eligible to obtain and maintain a U.S. security clearance.
• Must be willing to travel as projects require (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.

Compensation

• Base salary range: $120,000 - $160,000 USD annually (for the listed location).
• Total compensation package may also include equity, comprehensive health/dental/vision/life/disability insurance, 401k with employer match, learning/wellness stipends, and paid time off.
