About Luminary

Luminary is the AI-native system of action for wealth transfer services.

High net worth households controlling more than $90 trillion in assets are meaningfully underserved by technology that was built for the mass market. As private client investment and banking products have commoditized, these clients are looking for more tax and wealth transfer advice, advice that has previously been impossible to deliver at scale.

Luminary solves this problem by transforming complex estate planning and ownership documents into a structured, proprietary data asset that powers verticalized, agent-driven workflows for tax and wealth transfer services. Our built-in multi-firm collaboration connects a clients full advisor ecosystem, and is the core infrastructure that enables our customers to deliver a highly personalized, end-to-end wealth transfer service offering at scale.

Our 1,000+ customers are leaders across the private client services ecosystem: wealth managers from exclusive multi-family offices through top private banks and trust companies, national tax advisory practices, and law firms among the AM Law 100. Our focus and proprietary data position us to expand from a wedge in wealth transfer advice into large adjacent markets including trust administration and estate distribution.

Founded and led by CEO David Barnard, former Head of Wealth Management at AllianceBernstein, Luminary is backed by 8VC, Fin Capital, Rockefeller Capital, Focus Financial Partners, and several family offices.

How we work

• Every engineer ships to production multiple times a day. We make small, reviewable changes that go out through CI as soon as theyre ready.

• Modern tooling. Meticulous, Amp, Honeycomb, Temporal, PostHog, Braintrust. We keep the team small and invest in tooling for leverage.

• Engineers own outcomes. Youll talk to customers and feel their wins and pain points, sit with our in-house subject matter experts, and help us build a great business.

• We support both remote and in-office preferences. We have an office in NYC near Bryant Park and a lively in-office culture, but if remote works better for you, youll be in good company.
  

The Opportunity

Youll own features end to end. Youll hear an idea from a customer conversation, then craft the data model and build the interface an advisor uses while sitting next to a client. (Then the customer will email support to tell them how valuable it is for them!)

Youll work on features spanning document ingestion, knowledge graph generation, tax and wealth transfer modeling, multiplayer collaboration tooling, chat agents, complex diagram-based UI, and agentic advisory and trust administration workflows.

What youll do

• Build agents with agents. Most of what we ship now has an agentic surface: a chat affordance, an ambient agent working in the background, a tool a model can call. Youll be designing those, and youll be using coding agents (we use Amp) heavily to build them.

• Use existing patterns, and call out when one has stopped working. We have common conventions for data modeling, GraphQL, and component architecture, and they generally work! But not always, and youll know when to break out of them.

• Learn the domain from people who know it. Estate planning is complicated in ways that arent obvious from outside. Our wealth strategies team sits with engineers, and advisors, attorneys, and federal and state officials will take your call.

• Work closely with design. Experienced product designers, turning tax and legal concepts into something an advisor can use in a live client meeting.

Who you are

Four or more years of software engineering experience, at companies with strong engineering practices, and ideally at startups. Beyond that:

• Comfortable across the stack. You enjoy doing data modeling in Postgres, building product functionality in Go, and building interfaces in React and TypeScript. That said, we know youll lean one direction! We all do too.

• Product-minded. You gather context, watch customers use the app, form opinions about what customers need and share them.

• Technically skilled. Familiarity with cloud web applications and complex data models helps, as does familiarity with any of React, TypeScript, GraphQL (Apollo), Playwright, Go, Postgres, and Temporal. We arent dogmatic about any of it, and curiosity substitutes fine for experience.

• You communicate well. With half the team remote, overcommunication is the name of the game!

Why youll love working here

• Youll be one of a small, senior team of engineers building a complex and high-value product. Youll get a lot of trust and responsibility early on.

• Youll work closely with our CEO, Head of Engineering, and Head of Product.

• Youll help build foundational product in a nascent category, with a lot of room to expand into large adjacent markets.

• Youll ship constantly and hear fast feedback from customers.

We earnestly believe that Luminary represents a one-of-a-kind opportunity to have massive impact at profitable scale, and to have a ton of fun along the way.
