Responsibilities
Develop, refine, and maintain optimization algorithms in C++ using linear algebra techniques to support zero waste design outputs
Explore and implement multivariate optimization methods— from simplex to gradient-based and evolutionary algorithms— tuning for performance and robustness in production
Design and optimize custom cost functions for machine learning models, including hyperparameter tuning and loss shaping to improve practical outputs
Boost computational performance through algorithmic redesign, greedy heuristics, parallelization, and profiling at a low system level
Write modular, scalable, and clean code across C++, Python, and at least one additional systems language (e.g., Rust or JavaScript)
Analyze the time and space complexity of algorithms and systems, ensuring efficient performance at scale
Build and use internal debugging tools, visualizers, and test harnesses to speed up experimentation and improve engineering workflows
Collaborate with front-end engineers, 2D/3D designers, and researchers to integrate algorithmic solutions seamlessly into user-facing product features
Translate academic and theoretical breakthroughs into real-world, scalable solutions adopted by leading fashion and automotive partners
Qualification
Required
Experience implementing, improving, and maintaining optimization algorithms in C++ using linear algebra techniques (e.g., vector and matrix manipulation)
Comfortable with multivariate optimization methods—from classic simplex-style solvers to modern gradient-based and evolutionary approaches—and have a track record of tuning them for speed and robustness
Hands-on work experience with machine-learning algorithms that minimize or otherwise optimize cost functions, including custom loss design and hyperparameter search
Good at communicating the ins and outs of thorny technical problems in simple language, allowing team members to zero in on and demolish issues and bugs
Skilled in boosting ML/optimization performance through algorithmic redesign, greedy heuristics, parallelization, and low-level profiling
Familiar with object-oriented and functional programming paradigms, together with rigorous analysis of time and space complexity to keep web-scale pipelines snappy
Proficient in C++ and Python, and at least one additional systems language (e.g., Rust or JavaScript for WebAssembly) for bridging core solvers to the product front end
Comfortable dogfooding internal tools—building quick-turn scripts, debuggers, visualizers, and test harnesses that shorten feedback loops for yourself and the wider team
Collaborative and excited to partner with designers, front-end engineers, and researchers to translate algorithmic advances into intuitive product features that drive our zero waste mission
Energized by turning cutting-edge research into scalable, user-ready tools, and love solving hard, technical problems that have meaningful, real-world impact
Benefits
