Senior Software Engineer-Creo Core
Hybrid-Boston, MA
About the Team
The Creo Core team is responsible for the backbone of the PTC Creo product, one of the company’s flagship offerings. This team owns and advances one of the most critical capabilities of the Creo CAD modeler: the state-of-the-art 3D geometry kernel that powers industrial grade design and engineering workflows. Our work enables PTC to remain a leader in the global CAD market by delivering best in class, mathematically robust 3D modeling performance.
About the Role
As a Senior Software Engineer, you will work at the intersection of numerical methods, computational geometry, and high-performance C++ engineering. You will implement and improve core algorithms that directly affect model robustness, regeneration, geometric accuracy, and the user’s ability to build reliably complex designs.
This is a hands-on engineering role in which you will dive deep into the world of 3D geometry, develop mathematically sophisticated features, and help modernize and enhance critical components of the Creo modeling engine.
This role is ideal for engineers with strong mathematical intuition, experience in geometry-heavy or algorithmically complex systems, and a passion for solving problems involving accuracy, numerical stability, and large geometric datasets.
Key Responsibilities
Core Geometry & Algorithm Development
Implement, enhance, and maintain geometry kernel algorithms based on numerical methods, analytical geometry, and differential geometry.
Develop and refine modeling functions such as curve/surface operations, intersections, feature definitions, deformable geometry, and constraint behaviors.
Translate advanced mathematical concepts into efficient, production grade C++ implementations.
Performance & Reliability Engineering
Optimize algorithms for speed, numerical stability, and accuracy across large and complex models.
Analyze challenging geometry failures, identify root causes in modeling behavior, and implement robust fixes.
Work with multi-precision arithmetic, optimization techniques, or parameterized geometry where applicable.
Collaboration & System Integration
Partner with peer engineering teams, product managers, and QA to define requirements and deliver reliable modeling capabilities.
Participate in design reviews and provide clear explanations of algorithmic tradeoffs and geometric considerations.
Contribute to modernization efforts within the kernel, refactoring older components into more maintainable and scalable architectures.
Continuous Technical Growth
Expand your expertise in state-of-the-art geometric modeling and CAD algorithms.
Stay current with advancements in computational geometry, optimization, numerical methods, and applied math relevant to CAD.
Basic Qualifications
Ability to commute to the Seaport Boston office 2-3 days a week.
MS or higher in Mathematics, Applied Mathematics, or Physics (required).
BS in Computer Science or equivalent experience (preferred).
3+ years of hands-on C/C++ development experience.
Background in math algorithm development, computational geometry, numerical modeling, or mechanical 3D design (advantageous).
Strong understanding of data structures, algorithms, and problem-solving techniques for mathematically complex systems.
Excellent communication skills with the ability to explain complex mathematical or geometric concepts clearly.
Preferred Qualifications
Experience with algorithmic optimization, numerical stability techniques, or large-scale geometric computation.
Familiarity with multi-precision arithmetic, gradient-based methods, or advanced numerical libraries.
Exposure to computational geometry, point cloud processing, or geometric modeling research.
Comfort working in large legacy codebases and contributing to architectural modernization.
Ability to translate advanced mathematical reasoning into efficient and reliable software.
Success in This Role Looks Like
Delivering reliable, performant geometry features with measurable accuracy or robustness improvements.
Solving geometric and algorithmic challenges that require mathematical depth and careful reasoning.
Building trust with adjacent teams through thoughtful communication and high-quality engineering outputs.
Demonstrating ownership of subsystems and contributing to long term improvements in modeling quality.
