About the role

View original

Run a team that owns the physics architecture: Define data models, simulation loops, solver strategies, and integration points across engine and simulation systems.

Deliver core physics features: Collision detection (broad ‑ phase/narrow ‑ phase), entity controllers, vehicle dynamics with an emphasis on orbital mechanics, particles/fluid mechanics (with an emphasis on atmospheric dynamics).

Integrate with simulation logic (gameplay) & animation: Build physics ‑ driven interactions, authoring tools, and runtime hooks (e.g., inverse kinematics, state machines, event systems).

Performance ownership: Profile, optimize, and budget frame time and memory across platforms; lead multi-threading/Job System/SIMD efforts; evaluate GPU compute opportunities.

Stability & robustness: Establish test suites, golden scenarios, and verification and validation practices; reduce edge ‑ case instability (stacking, tunneling, jitter, constraint drift).

Tooling & workflow: Build/debug tools, visualizers, probes, and authoring pipelines that accelerate designer iteration and QA efficiency.

Cross ‑ functional leadership: Partner with back-end, AI, data pipeline, and platform teams; communicate constraints/trade ‑ offs; align milestones with production.

Mentorship & standards: Guide engineers via code reviews, design docs, and coding standards; cultivate a high bar for craft, documentation, and reproducibility.

Quality & live support: Own crash triage and regression control for physics; support content changes post ‑ launch without destabilizing the simulation.

Design, implement, and optimize real-time rendering pipelines (e.g., forward, deferred, ray tracing).

Develop and maintain shaders using HLSL, GLSL, ShaderLab, or Shader Graph.

Responsible for graphics API Integration work with low-level APIs like DirectX 11/12, Vulkan, Metal, or OpenGL ES.

Guide junior and mid-level engineers, conduct code reviews, and enforce best practices across studio teams.

Take responsibility for major subsystems (e.g., lighting, post-processing, material systems).

Work closely with artists, designers, and other engineers to align visual goals with technical feasibility.

Help technical artists create efficient content workflows and troubleshoot visual issues.

Translate deep technical topics into actionable insights for studio and platform teams and leadership.
