Full Job Description
The Opportunity

You'll own features end to end. You'll 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!)

You'll 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 you'll 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. You'll be designing those, and you'll 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 you'll know when to break out of them.
  • Learn the domain from people who know it. Estate planning is complicated in ways that aren't 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 you'll 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 aren't 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 you'll love working here
  • You'll be one of a small, senior team of engineers building a complex and high-value product. You'll get a lot of trust and responsibility early on.
  • You'll work closely with our CEO, Head of Engineering, and Head of Product.
  • You'll help build foundational product in a nascent category, with a lot of room to expand into large adjacent markets.
  • You'll ship constantly and hear fast feedback from customers.

Benefits we offer

We believe firmly that happy, healthy employees do their best work. To that end, we offer:
  • 100% employee health insurance coverage (plus 50% dependent coverage)
  • Monthly wellness, commuter, and educational stipends
  • 4 weeks PTO, plus holidays
  • NYC office near Bryant Park, for those who want it. Remote-friendly by default.
  • 401(k) plan
  • Parental leave policy


Compensation
  • Base salary range of $170k-$225k, plus meaningful equity. Actual compensation depends on many factors, including relevant experience and skillset.
  • At this time, Luminary is unable to sponsor employment visas or provide immigration support.
