Member of Technical Staff, Platform Engineer
About the role
As a Member of Technical Staff focused on Platform, you'll own the foundation everything else runs on — the infrastructure, backend systems, and developer experience that let a 12-person team ship agents into a regulated, high-stakes wealth management domain without slowing down. Agents are the primary users of the system of record, operating at scale across every client, all the time. That puts unusual demands on the platform — reliability, cost, and performance aren't afterthoughts, they're the product. You'll build core infrastructure and backend systems, safe execution environments for AI agents, developer tooling, and performance/cost optimization as Arca scales across multiple acquisitions this year.
About Arca Wealth
Arca is a wealth management firm built from the ground up with AI. Most people get financial advice that's reactive: an annual check-in, a plan that's a document instead of a living thing, a relationship where you're one of three hundred clients your advisor is trying to remember. Arca is rebuilding wealth management from the inside with AI — an Iron Man suit for advisors that takes over the low-leverage work so they can focus on what actually requires a human: showing up with empathy, context, and judgment. The platform keeps a living understanding of each client, notices when life changes happen, and adjusts before clients think to ask. Started by acquiring firms managing over $1B in client assets, giving real advisors, real clients, and real financial outcomes to build against from day one.
