Sr. Software Engineer, 3D C++

This position is for a Senior Software Engineer to join the Product CX CI Team, delivering customer-facing features. The engineer will lead feature delivery across computational geometry, treatment planning logic, and backend services, and act as a technical anchor on the team.

• Own features end-to-end — from requirements clarification and architecture through implementation, review, release, and post-release monitoring
• Design and implement 3D geometrical and numerical algorithms in C++ for customer-facing planning scenarios (doctor-facing and CAD)
• Contribute to backend services in Go supporting the customer-facing applications
• Lead architecture discussions; propose, defend, and close technical trade-offs with clear reasoning
• Drive clarification of ambiguous or incomplete requirements together with Business Analyst, Product Manager, and QA.
• Coordinate directly with adjacent teams on cross-team dependencies — own the outcome
• Set the quality bar in code reviews; mentor junior and mid-level engineers through reviews, pairing, and design guidance
• Work closely with the SQA team; contribute to test infrastructure and testability of the code you write
• Maintain traceability and regulatory documentation for medical software, following documentation-as-code practices

• Degree in Computer Science, Mathematics, Physics, or Engineering
• 8+ years of hands-on software engineering experience in a product team
• Demonstrated ownership of multiple non-trivial features taken from requirements to production
• Track record of technical leadership on at least one complex feature or subsystem
• Strong expertise in modern C++ (C++14/17 or later), deep knowledge of STL
• Experience building high-performance numerical or geometry algorithms
• Practical experience building backend services in Go, including HTTP/WebSocket endpoints
• Familiarity with gRPC and Protocol Buffers
• Ability to write testable, object-oriented code; strong opinions on design and testability
• Solid understanding of algorithms; experience with 3D geometry, linear algebra, or analytical geometry is a strong advantage
• Experience with Git and CI systems (Bamboo or equivalent)
• Working knowledge of Python for tooling and scripting
• Upper-intermediate English (B2 or higher)

• Health and well-being programs to keep you thriving in both body and mind.
• Employee-exclusive discounts on Invisalign products.
• Learning opportunities through online learning resources and support for your individual development plans.
• Inclusive, global workplace that fosters collaboration, recognition and belonging.
