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.\nOur 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.\nAt 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.\nWe're backed by a16z and Sam Altman, and currently power over $1 billion in assets under management.\nWhy Join Titan\nFor the right person, this will be one of the most rewarding roles they ever have.\nLegacy-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.\n\nThe time is now. LLMs just unlocked what was impossible five years ago: truly personalized wealth management for everyone.\n\nOutsized 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.\n\nBuilt 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.\n\nOwnership in every sense. Competitive cash and well-above-market equity. We believe in identifying only exceptional talent and compensating them generously.\n\nWorld-class backing. Investors who share the bold vision: a16z, General Catalyst, Accel, Y Combinator, Sam Altman, Paul Graham, and more.\n\nRole Overview\nTitan 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.
