Software Engineer - Frontend

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 client's 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 they're ready.

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

• Engineers own outcomes. You'll 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, you'll be in good company.
  

The Opportunity

Estate planning is a field where there is an iceberg of underlying complexity. A single family might have a dozen trusts, several entities holding assets across them, beneficiaries and trustees who appear in multiple structures but have conditional appointments, and provisions that only take effect under conditions years away. Advisors currently hold that picture together with documents and institutional memory – and human memory is highly fallible. A few firms have tried to record some of these details in Excel spreadsheets, but most don't even try.

Luminary's job is to make it legible instead. We use frontier models to extract the structure from the documents, surface it to our users in easily digestible forms, model the tax and distribution consequences, and connect the client's full set of advisors to the same view. Your job is the part the advisor actually touches: interfaces for reviewing extracted data, editing complex structures, proposing changes, and presenting the whole thing to a client. There is a mix of work on chat agents, surfacing details about what's happening with ambient agents behind the scenes, building complex diagramming tools, and much more.

What you'll do

• Build AI-native interfaces. You'll build agent chat surfaces that know what the advisor is looking at, ambient agents whose work has to be visible and reviewable, diagrams of entity structures with dozens of relationships, and views that make the implications of a multi-decade projection obvious at a glance.

• Own the frontend architecture. Component patterns, Apollo cache and state management, performance, and the shared primitives everyone else builds on top of.

• Partner with design. Day to day with experienced product designers and our Head of Design. We want your opinions early, while things are still cheap to change.

• Finish things. Empty states, loading behavior, and keyboard paths are the littl
