Principal Backend / Infrastructure Engineer – TypeScript

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.
