Game Engine Engineer, Platform

Key Attributes:

• Innovation Mindset: Passion for pushing the boundaries of real-time physics in interactive simulation.
• Coding-Skills: expertise in coding languages, including C++ and game scripting.
• Problem-Solving: Creative and analytical approach to complex simulation challenges.
• Communication: Clear articulation of technical concepts to non-technical stakeholders.

Responsibilities:

• Work on game physics: data models, simulation loops, solver strategies, and integration points across engine and simulation systems.
• Focus on 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).
• Help with performance optimization: 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.
• Quality & live support: work on crashes and regressions for the game engine; support content changes post-launch without destabilizing the simulation.

Professional Qualifications:

• Education: BS/MS in Computer Science, Software Engineering, Physics, Mathematics (or equivalent practical experience).
• Experience: 0 to 4+ years in real-time/game physics engineering; shipped a title, AA/AAA preferred.
• Programming: Experience C++ (modern standards), data-oriented design, memory management, profiling/debugging (VTune, PIX, Nsight, RenderDoc, etc.).
• Rigid-body dynamics,collision detection (GJK, SAT, continuous collision detection/time of impact), integration schemes (semi-implicit Euler, RK, constraint solvers).
• Numerical stability, error control, and performance trade-offs under real-time constraints.
• Engine Integration: Experience integrating physics with animation (animation blending, IK), gameplay systems, and rendering pipelines.
• Performance: Multi-threading/job systems, SIMD/vectorization, cache-friendly data structures, frame/memory budgeting across platforms.
• Collaboration: Proven ability to lead cross-disciplinary efforts and communicate complex technical topics clearly.

Preferred Qualifications:

• 2+ years’ experience in Modern Game Engines & Middleware: Unreal Engine (Chaos), Unity (DOTS/Physics), Havok, Bullet, PhysX; custom engine experience strongly preferred.
• 1+ years’ experience in Advanced Simulation: Fracture systems, granular materials, vehicle tire models, buoyancy/aero effects; GPU compute (CUDA, compute shaders).
• Experience with existing physics models and systems integration.
• Networking: Deterministic simulation strategies, rollback/prediction, server authority models, cross-platform latency mitigation.
• Console/Platform: Shipping experience on Xbox, PlayStation, Switch, and PC; familiarity with platform TRCs/TCRs and performance certification.
• Tooling & Scripting: Python/C#/Lua for tools and editor extensions; in-engine visualization/debugging overlays.
• Optimization Expertise: Broad-phase structures (sweep-and-prune, BVH), island building, sleeping strategies, CCD tunneling avoidance; job scheduling and affinity tuning.
• Content Pipelines: Collaboration with design/tech art to create authoring guidelines for physics assets; LOD strategies for physics complexity.
