## About the Role

outputs. Research Integration: Collaborating directly with researchers to embed OPynSim into active research pipelines, gathering feedback to iteratively improve the software. Job requirements This role strongly requires: A master's or PhD degree in a STEM field, or equivalent professional experience in engineering scientific/research/3D software. Provable familiarity with software development (e.g. courses taken, work experience, example code/projects). Expertise in any of these topics is highly desirable: Developing software for larger systems with legacy compatibility concerns. Especially systems written in C++/Python. C++ and its surrounding ecosystem (e.g. CMake, googletest, stdlib). Python and its surrounding ecosystem (e.g. PyPi, numpy, pandas, polars, pytest). Especially idiomatic Python API design, and the specifics of the Python language. Language interoperability and foreign function interface (FFI) design. Especially using nanobind and pybind11 to create Python

## Description

project's requirements, your responsibilities may include: Core Engine Development: A core part of the role will be contributing to the underlying C++ codebase, focusing on physics engine development, performance optimization, and musculoskeletal modelling capabilities. Language Interoperability: Developing seamless Python bindings to C++ using tools like nanobind, ensuring excellent language interop and a Pythonic user experience without sacrificing performance. Greenfield Innovation: Taking ownership of standalone sub-projects and novel ideas leveraging OPynSim, driving self-managed, clean-slate software development. Quality Assurance: Implementing rigorous unit testing workflows using GoogleTest for C++ and pytest for Python to ensure software reliability and robustness. Writing Documentation, Examples, and Specifications: Authoring clear technical specifications and user-facing documentation using Sphinx to empower the global research community and polish the project's
