• Contribute to open-source projects and help define engineering best practices.
• Expand your skill set across the stack (e.g., Rust, ML) as the company grows.

SKILLS

• Masters or PhD in Comp Sci from a globally recognized institution
• Strong technical background with experience leading front-end projects from inception to deployment.
• Deep expertise in front-end development, particularly with React and modern frameworks.
• Passion for design and building developer tools that are both functional and delightful.
• Eagerness to learn and grow in a fast-paced, high-ownership environment.
• Preference for in-person collaboration in a high-energy NYC office.

BENEFITS
