Description:
This position is for a Senior Software Engineer to join the Product CX CI Team — a vertical team delivering customer-facing features (doctor-facing and CAD) at Align Technology.

As a Senior C++ Software Engineer, you will lead feature delivery end-to-end across computational geometry, treatment planning logic, and backend services — owning technical decisions from requirements through release.

This role is expected to act as a technical anchor on the team: raising the engineering bar, closing technical decisions without escalation, and coaching less experienced engineers.
- Key Responsibilities:
- 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)
- 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
- Skills, Knowledge & Expertise:
- 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

C++ (primary):
- Strong expertise in modern C++ (C++14/17 or later), deep knowledge of STL:
- E
