The Role

We’re looking for a frontend-leaning product engineer. You’ll own features end-to-end from idea to implementation, working closely with design and product at a fast-moving startup.

We move quickly, debate openly, and work long hours. In-person, five days a week, NYC only.

Key Areas of Responsibility:

• Build high-quality React + TypeScript product experiences
• Own features from idea to launch to iteration
• Have a strong sense for UI/UX
• Improve frontend performance and product polish
• Work across the stack (Node.js, GraphQL, PostgreSQL, etc.)

What We’re Looking for

• 2-8 years of full-time experience
• Extremely strong TypeScript experience
• Strong React experience
• Frontend-first with solid product taste and attention to detail
• Comfortable with backend, but not infra-focused
• Startup mindset: high ownership, speed, and comfort with ambiguity

Comp: $150K-$250K + meaningful equity

In-person, five days a week, NYC only.
