Principal Backend / Infrastructure Engineer – TypeScript

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.
