Front End Product Engineer - AI Decision Platform

*Build the UI for an AI Decision Platform | Front End Product Engineer | NYC*

About the Opportunity

We’re a high-velocity AI startup building a new kind of decision-making system: software that turns complex inputs into clear, actionable outcomes through intuitive, beautifully crafted interfaces. Our product lives at the intersection of human judgment and machine intelligence, and we believe great UX is the difference between “interesting AI” and software people can’t live without.

We’re hiring a Front End Product Engineer who is equal parts builder and craftsperson. Someone who sweats the details, loves refining pixels, and knows how to turn a powerful backend into a product that feels simple, fast, and delightful.

Location: Hudson Yards, New York City

Work Model: 5x/week in-office (this is an in-person role)

What You’ll Do

As a key member of our engineering team, you’ll own the front-end experience for an AI-driven product and help define how users interact with intelligent workflows.

You will:

• Build and maintain a SvelteKit application, owning front-end architecture decisions, component design, and long-term scalability.
• Write clean, type-safe TypeScript across the stack, from reactive UI components to API integrations.
• Partner closely with design, research, product, and GTM to translate user needs into polished, production-grade experiences.
• Integrate commercial and custom AI models into intuitive workflows that help users move from question → insight → decision.
• Establish front-end patterns, standards, and practices that enable the product and team to scale confidently.
• Obsess over performance, accessibility, usability, and the “small things” that separate good software from great software.

We’re looking for a front-end engineer who can ship quickly without sacrificing craft.

You have:

• Deep experience building modern web applications using either Svelte, React, Vue, or similar frameworks.
• Strong product and UX intuition, with the ability to make thoughtful trade-offs independently.
• Proven ability to own features end-to-end, from early design collaboration through implementation, testing, and deployment.
• Experience with design systems and scalable component architecture.
• A high bar for detail, usability, and visual polish—you notice misalignment, inconsistent spacing, and “almost right” UI.

Bonus Points

Strong candidates may also have experience with:

• Building or integrating AI/ML-powered product features
• Tailwind CSS and utility-first styling approaches
• Performance optimization, bundle analysis, and UI responsiveness at scale
• Working in environments that run on Kubernetes-based infrastructure
• Alternative JavaScript runtimes like Bun
• Rapid iteration in early-stage startup environments where you ship, learn, and improve fast

Why This Role

• You’ll build a front-end that makes advanced AI feel human, usable, and trusted
• You’ll ship first-of-their-kind product experiences with real-world impact
• You’ll have significant ownership over the UI architecture and product direction
• You’ll work closely with a small, senior team that values speed, clarity, and quality
