About Titan

Titan is an award-winning wealth manager with a mission to increase our generation’s compound growth rate. We plan to do this by putting a human wealth advisor in every pocket. Historically, wealth managers have been accessible to only the ultra-wealthy. With Titan, they’re available to everyone. We harness frontier technologies like artificial intelligence to build a platform that gives advisors superpowers, enabling them to serve clients they historically never could. Backed by a16z, General Catalyst, Sam Altman, and many others, we manage over $1 billion in assets for clients across the country.

Why Join Titan

For the right person, we believe Titan will be one of the most rewarding jobs they ever have.

  • Ambitious Vision: When we put private wealth management in every pocket, we’ll make a legacy-defining impact in growing our generation’s wealth to new heights.

  • Critical Why Now: The advent of LLMs unlocks our vision to democratize personalized wealth management for everyone. This drives our urgency every day.

  • Disproportionate Impact: We’re still at the beginning of our journey with a small team, which means your impact at Titan will disproportionately matter.

  • Vibrant In-Person Culture: We thrive on being a high-touch team, working together in the trenches in person (you’ll see our founders in office every day).

  • Compensation: Titan offers competitive cash compensation and well-above-market equity packages because we want every team member to be an owner.

  • World-Class Investors: We’re backed by top investors who share our bold vision, including a16z, General Catalyst, Y Combinator, and Sam Altman.

Role Overview

Titan is looking for a Principal Full Stack Engineer who can ship end-to-end features that span web and mobile surfaces. You’ll partner closely with Product, Design, and Backend teams to deliver seamless user experiences across both React (web) and React Native (mobile) applications. The ideal candidate thrives on solving real, user-facing problems with elegant design and engineering excellence.

Core Responsibilities

  • Build and maintain customer-facing products using React (web) and React Native (mobile).

  • Implement features end-to-end: frontend UI, backend API integration, data management, and performance optimization.

  • Collaborate with product designers to create intuitive, responsive UX across multiple platforms.

  • Identify opportunities to reuse components and unify shared UI patterns and tooling.

  • Ensure stability and high performance on both web and mobile through testing, metrics, and monitoring.

  • Contribute to backend endpoints where needed to support frontend features.

  • Advocate for scalable front-end architecture and clean, maintainable code.

Qualifications

  • 6 + years of professional experience building full stack applications.

  • Expert in JavaScript / TypeScript with hands-on experience in React and React Native.

  • Familiarity with mobile-first design principles and web/mobile performance considerations.

  • Experience integrating with backend services, RESTful APIs, and real-time data updates.

  • Comfortable operating across frontend and backend boundaries to ship cohesive products.

  • Excellent communication skills and ability to partner with product and design teams.

🧠 What Makes You Stand Out

  • Contributions to React or React Native open-source libraries.

  • Experience in fintech or regulated systems with strict reliability expectations.

  • Past work on consumer apps with rapid release cadences.

  • Thought leadership on frontend architecture and tooling.
