Senior Software Engineer (3D Geometry)

About the role

We’re hiring an experienced software engineer with strong foundations in mathematics, physics, and 3D geometry to join our team revolutionising the creation of complex digital assets for the fashion industry.

We’re looking for somebody well-versed in modern software development practices with a strong desire to apply their mathematics and/or physics skills in a practical context to deliver best in class product development.

Responsibilities

• Develop robust automated processes for producing digital assets for the fashion industry, leveraging cutting edge research and technologies where you see fit.

• Design and implement tools for configuring, managing, and validating simulation workflows as part of a larger content pipeline.

• Work alongside wider infrastructure teams to ensure tools operate reliably at scale and across distributed compute environments.

• Integrate tools with third party software such as Unreal Engine and USD-based asset frameworks.

• Collaborate in the production of 3D content, and work with designers to validate realism and accuracy of our models.

• Establish testing and QA procedures to ensure stability, reproducibility, and correctness of procedural/automated 3D modelling processes and/or simulation outputs.

Requirements

• Bachelor's or Master’s in Computer Science, Engineering, Physics, or a related field.

• 5+ years using Python, with experience developing production-grade tools or pipelines.

• Exceptional mathematical skills, especially in linear algebra.

• Strong problem-solving ability with comfort in simulation, procedural systems, or numeric computation.

• Experience with 3D software platforms (Blender, Unreal Engine, Houdini).

• Understanding of QA methodologies for 3D content at scale.

• Familiarity with asset-based workflows and scene description tools (USD).

• Comfortable using version control systems like Git.

Preferred Qualifications

• 3+ years experience in the CGI or Video Games industry.

• Confidence with physics-based simulation concepts, especially cloth, soft body, or particle dynamics.

• Knowledge of orchestration tools, batch processing, or compute scheduling.

• Exposure to C++ and some development experience in Unreal.

• Exposure to data curation for or implementation of AI/ML systems.

Beneficial Qualifications

• Experience modelling digital garments using software such as CLO3D, Marvellous Designer, Blender, or Maya.

• Knowledge of real-life garment creation, including pattern cutting, tailoring, grading, sewing, and finishing. 

• Experience designing or debugging tooling that interfaces with proprietary or third-party physics solvers (Houdini Vellum, NVIDIA Warp, or similar).

• A deep understanding of materials modelling (anisotropic, hyperrealistic) and its application to real-world simulation and rendering.

What working with CATCHES is like:

• Fully remote-first, async-friendly, with optional co-working allowances.

• High-trust, low-bureaucracy environment that values experimentation and shipping.

• Early influence on product, architecture and engineering culture.

• A small, experienced team that cares about sustainable pace.

• Cutting-edge tech, luxury-fashion creativity, and game-industry scale challenges combined.
