• Build pipelines for reading, validating, transforming, and exporting IFC / OpenBIM models.
• Analyse complex problems and propose innovative solutions that align with business objectives.
• Collaborate closely with cross-functional teams (design, engineering, BIM, and product) to integrate software components seamlessly.
• Support and guide less experienced colleagues by sharing knowledge, conducting code reviews, and promoting best practices.
• Contribute to continuous improvement by identifying opportunities to enhance development processes, tooling, and automation.
• Participate in agile ceremonies, contribute to key technical decisions, and document solutions and design rationale.

Candidates must demonstrate the following

• 1 Rhino / Grasshopper development experience, including custom components, scripting, and plugin development.
• 2 Python: strong proficiency in writing clean, maintainable, production-quality code.
• 3 IFC / OpenBIM standards and model processing experience (e.g., IFC schemas, property sets, model validation, and data extraction / transformation).

Good-to-Have Skills

• 1 Speckle (connectors, data streaming, and collaboration workflows).
• 2 Computational design, geometry processing, and automation workflow development.
• 3 Node.js / React.js for building supporting web applications and services.

Qualifications & Experience

• 5-8 years of relevant working experience in software engineering, ideally within AEC, BIM, or computational design domains.
• Expert proficiency in Software Engineering; advanced proficiency in Custom Application Development and Software Design & Solutions.
• Bachelor's degree in Computer Science, Software Engineering, Architecture / Engineering (with strong programming background), or equivalent experience.
• Proven experience working in agile teams and delivering scalable, high-performing solutions.
• Strong problem-solving, communication, and stakeholder-management skills, with the ability to mentor and lead.
