Senior Frontend/Mobile Engineer Onsite (New York City, NY)

We're hiring a Senior Frontend Engineer to help build and scale the app that thousands of sports fans use every day. You'll work across our React Native mobile app and React web surfaces, shaping the product experience as we grow from a fast-moving startup into the home for sports betting.

About Pikkit

At Pikkit, we're building the home for sports betting.

Today, we're a social sports betting app with over 1 million users , 20,000+ five-star reviews , and more than $30B in legal U.S. sports wagers tracked through our app. We're featured in industry reports from Citizens Bank, Houlihan Lokey, SBC, and more, and backed by top-tier VCs including Founder Collective, Baukunst, and Matrix.

We're a team of ~15, all in-person at our Flatiron NYC office. We move fast, ship high-quality product, care deeply about sports fans, and don't take ourselves too seriously.

About the Role

This role owns how Pikkit looks, feels, and performs for our users. You'll take ownership across our React Native mobile app and React web app, building polished, fast, delightful interfaces that scale with a rapidly growing user base.

The unifying thread is product craft: writing clean, maintainable frontend code, but also having the judgment to know what to build, how to architect it, and how to tell if it's working. We don't expect deep experience in our exact stack, but we do expect strong engineering fundamentals and a genuine interest in reliability, scalability, and product experience.

This is a very hands-on, senior role. You'll be writing code, shaping component and page architecture, instrumenting what you build, and partnering closely with product and design to compound our velocity. We're a small, AI-leveraged team, so you should be comfortable using AI tools like Claude Code and Cursor as part of your everyday workflow, not just curious about them.

What You'll Do

As Frontend Engineer, you will:

• Build and scale core features across our React Native mobile app and React web app

• Own frontend architecture decisions, from component design to page structure, that keep our codebase fast, maintainable, and easy for the team to work in

• Translate product and design vision into polished, performant user interfaces, with strong instincts for what will actually work for users

• Instrument what you build with analytics, and use that data to inform what to build next

• Improve app performance, from load times to animation smoothness to overall responsiveness

• Identify bottlenecks in how we ship frontend features and remove them

• Set the standard for frontend quality and craft at a small, fast-moving team

What We're Looking For

• 4+ years of software engineering experience building at the product/application layer, with a focus on frontend engineering

• Deep experience with React and/or React Native; experience with Expo is preferred, and comfort with Node, AWS, MongoDB is a plus

• A strong product mind and good user intuition, someone who can push back on a spec, not just implement one

• A good sense of component design and page architecture, and how to keep a growing codebase clean

• Experience adding analytics/instrumentation and using it to drive product decisions

• Comfortable owning a domain end-to-end and thriving in ambiguity, startup or significant personal project experience is a major plus

• AI-forward: you actively use AI coding tools in your day-to-day work and want to keep pushing on how AI can make you faster and better

• Interest in sports or sports betting is a plus

Benefits

• Competitive salary and equity

• Health, dental, and vision insurance

• Unlimited vacation

• Generous budget for laptop and equipment

• Fun in-person team events

• Office in Flatiron, NYC
