• Collaborate closely with the AI team and machine learning algorithms to improve the system
• Write clean, well-structured, and well-documented code, following best practices for maintainability, testability, and scalability.
• Contribute to technical documentation and knowledge sharing across the team to support ISO and regulatory standard.

• Strong adherence to software engineering best practices — version control, modular design, automated testing, and documentation.

Nice-to-Have:

• Experience working with or extending 3D libraries (e.g., PCL, Open3D, trimesh, or similar).
• Familiarity with C++ for performance optimization or low-level geometry manipulation.
• Exposure to cloud functions, containerized services, or serverless deployments (e.g., AWS Lambda, ECS, S3 pipelines).
• Background in 3D modelling tools (e.g., Blender, Fusion 360)
• Background in a startup or fast-paced engineering culture.
