Workplace: Onsite
Employment Type: Full time
Job Function: Software Engineering

Key Responsibilities

  • •Build the software engineering backbone of the Genesis-World simulation codebase to make it reliable, maintainable, and frictionless.
  • •Make testing of a JIT-compiled engine scalable by removing compile/runtime bottlenecks across the suite.
  • •Ensure any bug is reproducible by enabling bit-exact dump/reload across machines and backends and generating standalone reproduction scripts.
  • •Make autodiff first-class by driving requirements across the engine and compiler and iterating tightly with the compiler team.
  • •Refactor and improve core engine capabilities, including instant frozen-time scene editing and extensible plugins for physics solvers and viewer backends.

Key Requirements

  • •Strong Python engineering on large codebases, including architecture, refactoring, typing, packaging, and performance profiling (py-spy, Nsight, Xcode Instruments, RenderDoc).
  • •Experience with developer tooling, test infrastructure, or CI at scale.
  • •Fluency with JIT compilation, code generation, or GPU computing stacks to reason about compilation caching, kernel dispatch, and startup cost (working closely with Quadrants).
  • •Ability to debug across the platform matrix (Windows, Linux, macOS; x86 and arm64; CUDA, AMD, Apple Metal).
  • •Open-source collaboration experience, including triaging issues, reviewing external pull requests, and communicating with a community.
