Founding Product Designer
Full-time
New York City
Flint is reimagining how students learn with AI. We're building the core teaching and learning platform for K–12 schools — one that delivers personalized learning at scale while making teachers' lives easier, not harder.
We’ve been heads-down for the past two years and now work with 200+ schools across the U.S. and around the world.
We’re backed by Y Combinator (S23) and led by a lean, fast-moving team. You’ll join at the ground floor, working directly with the founders (second-time founder CEO and ex-Googler CTO) and a small group of engineers to ship ambitious, thoughtful products that power real classrooms.
🎨 What you’ll do
We’re in the middle of a major product revamp. As our first full-time designer, you’ll:
Own UI/UX across the product — from concept to polish
Partner closely with the founders, engineering team, and customer success team
Interview teachers and students to deeply understand the classroom
Translate product direction, business needs, and technical constraints into clear, classroom-friendly interfaces
Use AI to speed up prototyping and iteration
Ensure consistency and harmony across the product — so it feels intuitive, clean, and all the pieces work together
✅ Minimum requirements
Strong visual and UX design skills — you can take a messy idea to clean, usable UI
Experience designing software products end-to-end
Comfortable collaborating closely with stakeholders to align on goals and constraints
Able to work in-person in NYC
🌟 Preferred qualifications
Experience running user interviews or usability studies — especially with teachers or students
Familiarity with K–12 classrooms or edtech products
You move quickly using AI to generate mockups or accelerate iteration
🚀 Why join now?
Massive impact. Own high-leverage features and immediately witness their impact
Fast growth. Work with a tight-knit team, ship fast, and level up quickly
Strong benefits. Competitive salary, generous equity, and health/dental/vision insurance
Right timing. With AI, this is the moment to reshape classrooms and make personalized learning real
