Role Overview
Titan is looking for a Senior 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
- 3 + 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.
About Titan
Despite decades of innovation in money, the most important consumer money domain remains largely untouched: wealth management. Legacy Wall Street institutions still dominate private wealth, gatekeeping their services behind extremely high minimums, janky user experiences, and layers of fees. They are, in our opinion, the "final boss" of consumer fintech.
Our belief: every American deserves an elite wealth team navigating their capital, delivered at the cost and speed only humans working in harmony with AI can unlock.
At heart, we're a small pack of hard-working rebels operating at the intersection of engineering craft and high-stakes financial precision. Every person here is a calibrated bet on what we're building next. Our mission is to rebuild what a wealth management firm means, from the ground up, brick by brick, leveraging technology across the entire stack, so that AI lets one wealth advisor deliver what used to take a team, serving clients a Wall Street team never could have reached.
We're backed by a16z and Sam Altman, and currently power over $1 billion in assets under management.
Why Join Titan
For the right person, this will be one of the most rewarding roles they ever have.
- Legacy-defining vision. Private wealth in every pocket isn't an incremental product. It’s not B2B automation. It’s a “before & after” moment in money.
- The time is now. LLMs just unlocked what was impossible five years ago: truly personalized wealth management for everyone.
- Outsized decision making. We're a small team by design. Every hire is precise, every role carries real weight, and your decisions disproportionately shape what we become.
- Built in person, in the trenches. We're a high-touch, high-tempo group that works side by side. You’ll see our founders working in the trenches with the team everyday.
- Ownership in every sense. Competitive cash and well-above-market equity. We believe in identifying only exceptional talent and compensating them generously.
- World-class backing. Investors who share the bold vision: a16z, General Catalyst, Accel, Y Combinator, Sam Altman, Paul Graham, and more.
