About the Position

Sr Staff Software Engineer (R&D Engineering)

Synopsys is seeking a Senior Staff Software Engineer for its R&D Engineering team based in Madrid, Spain. This is a fully remote position, and candidates must be currently residing in Spain or willing to relocate prior to joining the company.

Responsibilities

• Design and develop Python libraries for PyAnsys, building APIs and frameworks that make Ansys simulation tools more accessible, scriptable, and integrated into modern engineering workflows.
• Lead architecture and technical planning across multiple projects within the PyAnsys ecosystem, coordinating with engineering teams across Ansys business units to align on priorities, interfaces, and release schedules.
• Work at the boundary between Python and compiled languages like C++ or C#, building bindings, wrappers, and integration layers that preserve performance while improving usability.
• Define and enforce best practices for library design, testing, documentation, and release management, conducting technical reviews and mentoring engineers to raise the quality bar across the team.
• Collaborate directly with Ansys product teams and strategic users to understand requirements, prototype solutions, and validate that what you are building actually solves the problems engineers face in production.
• Debug complex issues that span Python, compiled code, and the underlying Ansys solvers, coordinating with QA and support teams to ensure problems get resolved and do not resurface.
• Represent the PyAnsys effort in technical discussions with leadership, customers, and the open source community, translating between business goals and engineering reality.

Requirements

• Core Skills:

  • Deep expertise in Python for building libraries, frameworks, or developer tools.
  • Strong understanding of API design, packaging, testing, and open source development practices.
  • Hands-on experience with compiled languages like C++ or C#, including work on performance-critical code, interoperability, or binding layers between Python and lower-level systems.
  • Proven ability to lead technical efforts across multiple teams or business units, driving alignment on architecture, priorities, and execution in ambiguous or politically complex environments.
  • Fluent written and spoken English, with demonstrated ability to communicate technical concepts clearly to engineers, product managers, and leadership across global teams.

• Secondary Skills:

  • Experience with simulation software, scientific computing, numerical methods, or engineering tools is a strong plus.
  • Track record of mentoring engineers, conducting design reviews, and raising the technical quality of a team or codebase.
