What We're Looking For

We are looking for a senior product designer to help us design groundbreaking technology that will transform the machine learning ecosystem and fundamentally change how the world experiences software. With a diverse skill set spanning product, interaction, and visual design, you are able to create products that are a joy to use and add tangible value to our users.

You will collaborate across product and engineering to bring user flows and designs to life while working closely with users to test new ideas, conduct research, and gather feedback. You thrive in a fast-paced, start-up environment with a focus on speed, quality, and iteration from proof of concept to release.

You will be joining the Design Team and report to our Chief Creative Officer. This is a hybrid role based in our New York City office with in-office requirements of 2 days per week. The salary range for this role is $160,000-$200,000.

What You’ll Do

Collaborate with product and engineering teams to shape the user experience, interface, interactions, and visual design of new and existing features. Act as a key design partner in defining product strategy throughout the end-to-end development process.
Craft user journeys, flows, prototypes, and designs—sometimes starting from scratch, other times by refining early engineering prototypes or providing design enhancements and guidance as products evolve.
Proactively identify design opportunities and drive continuous improvement based on business objectives, user requirements, and customer requests.
Engage with the open source AI community and enterprise AI researchers and builders to understand real-world needs, workflows, and challenges—bringing those insights directly into the product design process.
Discover creative ways to eliminate friction and reduce papercuts through design, making it easier for users to onboard and utilize our platform from day one.
Advocate for scalable, user-centered design systems and processes that improve design velocity, consistency, and impact across the product.

What You’ll Need

5+ years of experience designing B2C software or technical platforms, preferably in developer tools, AI/ML, or SaaS environments
Strong portfolio showcasing end-to-end product thinking across UX, interaction, and visual design
Experience working with product managers, engineers, and researchers to iterate quickly and ship thoughtfully
Curiosity and initiative in engaging with the open source AI ecosystem, and a desire to understand the needs of both individual contributors and enterprise AI teams
Comfort working in ambiguity and across multiple product maturity levels—from early-stage prototypes to production features
Proficiency in Figma and modern design tools
Familiarity with technical concepts like machine learning, APIs, or cloud infrastructure (not required, but a plus)
Excellent communication skills, with the ability to present design rationale clearly and influence cross-functional teams
A mindset of continuous learning, user advocacy, and pragmatic design execution
Experience coding front-end is not required but a big plus!
