Core Software Engineer (Robotics)

Company

hirify.global is building the future of physical AI through Genesis-World, an open-source, general-purpose simulation platform for robotics.

What you will do

• Develop the software engineering backbone of the Genesis-World platform to ensure reliability and maintainability.
• Optimize testing infrastructure for a JIT-compiled engine to eliminate compile-time bottlenecks.
• Implement bit-exact simulation reproduction and automated standalone reproduction scripts for debugging.
• Drive the integration of differentiable simulation features in collaboration with the compiler team.
• Refactor legacy subsystems and improve scene serialization, telemetry, and replay capabilities.
• Review issues and pull requests while engaging with the open-source community.

Requirements

• Location: Must be based in or able to work from Paris or London (Hybrid).
• Strong Python engineering experience on large codebases, including architecture, refactoring, and performance profiling.
• Experience with developer tooling, test infrastructure, or CI at scale.
• Fluency with JIT compilation, code generation, or GPU computing stacks (CUDA, AMD ROCm, Metal).
• Ability to debug across a full platform matrix including Windows, Linux, and macOS.
• Strong open-source reflexes and experience in community communication.

Nice to have

• Experience with robotics simulators like Drake, MuJoCo, Isaac, or Brax.
• Proficiency with PyTorch, Triton, JAX, or Numba.
• Knowledge of 3D tooling (Blender, Houdini) and serialization formats (USD, glTF, URDF).
• Experience with C++, CUDA, or Metal.

Culture & Benefits

• Work on a high-impact, open-source project that directly influences the robotics industry.
• Collaborate with a core team of physics and compiler experts.
• Opportunity to shape the architecture and API design of a next-generation simulation platform.
• Direct involvement in the open-source ecosystem and community building.
