Want to build something people talk about over dinner?

If you’ve shipped consumer apps and can spot issues before users ever see them, this one’s for you.

We’re a social investing platform reshaping how everyday users discover and follow investment ideas. With most of the mobile team currently located overseas, we’re hiring in NYC to boost U.S. presence and move faster on new features, from in-app social layers to launching a companion web experience.

This is your chance to own key parts of a mobile product in an ambitious, design-forward, high-growth startup. You’ll be working closely with product and design, shipping frequently, and having real say over how things get built.

What you’ll be doing

• Build and enhance features across our Flutter mobile app (iOS & Android)

• Work closely with product and design teams to deliver pixel-perfect user experiences

• Own performance, architecture, and reliability, this is your code in production

• Shape how the app evolves, contribute to roadmap decisions, and raise the bar on quality

• Ship quickly and often, you’ll be writing production code in your first week

This might be for you if…

• You’ve built Flutter apps for real users and know your way around the Dart ecosystem

• You understand state management, architecture, and can explain the difference between Stateful and Stateless widgets

• You’ve worked with RESTful APIs, written testable code, and deployed to the App Stores

• You thrive in startup environments and prefer autonomy over hierarchy

• You’re based in NYC (or willing to relocate) and open to being in the office 3+ days a week

Bonus points if you’ve worked with:

✅ Firebase, mobile CI/CD, React or Next.js, AWS services (S3, Lambda, API Gateway)

✅ A/B testing, design systems, or building social features

What next?

The process is simple:

1. Intro call

2. Technical chat with engineering

3. Product-focused interview

4. Final conversation with leadership

Apply now and we’ll share the full info pack, walk you through the process, and answer any questions.

This isn’t just a job building mobile features. It’s a rare chance to help shape the future of consumer investing, alongside a small team that moves fast and builds thoughtfully.
