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.\nLuminary 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.\nOur 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.\nFounded 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.\nHow we work\nEvery engineer ships to production multiple times a day. We make small, reviewable changes that go out through CI as soon as they're ready.\n\nModern tooling. Meticulous, Amp, Honeycomb, Temporal, PostHog, Braintrust. We keep the team small and invest in tooling for leverage.\n\nEngineers 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.\n\nWe 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.\n\nThe Opportunity\nA family's estate plan structure rarely fits neatly into a schema. A trust may have been amended three times, an LLC might be held by two of the children through a different trust, and a beneficiary is often also a trustee. Provisions frequently depend on conditions that haven't happened yet.\nModeling that correctly is the first half of the job. The second is computing against it, which is where our tax engine comes in: estate and gift tax, generation-skipping transfers, strategies like GRATs and ILITs and QPRTs, and projections that ask what happens if a business grows sharply in value ten years from now and how that changes a family's charitable and family giving goals. As far as we know, it's the most complete implementation of the US transfer tax code in software anywhere.\nYou don't need to have worked on any of this before! None of us had. We're looking for someone who likes modeling complicated real-world systems accurately, and who wants to learn a deep domain from the JDs and CPAs on staff.\nWhat you'll do\nOwn the modeling engine. Transfer tax computation, waterfall and distribution modeling, and the consolidation work that brings our calculations under one engine.\n\nModel the domain flexibly and thoughtfully. Trusts and estates are complex and have a lot of moving parts. Data modeling is a really important part of this role.\n\nMake correctness checkable. You'll work with our JDs and CPAs to validate against how practitioners compute things. We regularly talk to various state attorneys general to dig into the nitty-gritty of how specific interactions work in their tax code.\n\nSupport our agents. Extraction and agentic workflows are only as good as the data model they write into. We don't want agents doing any math, so we expose this deterministic layer (and the ability to do hypothetical modeling) via tools.\n\nWho you are\nFour or more years of software engineering experience, at companies with strong engineering practices. Beyond that:\nYou prefer domain complexity to infrastructure complexity. The hard part here is modeling an intricate real-world system correctly, not scaling a queue.\n\nRigorous about correctness. You think in edge cases, and you're uncomfortable shipping logic you can't verify.\n\nProduct-minded. You want to know why a calculation matters and who depends on it. You'll be shaping requirements, not receiving them.\n\nDay to day tools\nOur backend is Go, Postgres, Temporal, and GraphQL\n\nOur monitoring is mostly in Honeycomb, Braintrust, and PostHog\n\nYou communicate well. With half the team remote, overcommunication is the name of the game!\n\nWhy you'll love working here\nYou'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.\n\nYou'll work closely with our CEO, Head of Engineering, and Head of Product.\n\nYou'll help build foundational product in a nascent category, with a lot of room to expand into large adjacent markets.\n\nYou'll ship constantly and hear fast feedback from customers.\n\nWe 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.\nBenefits we offer\nWe believe firmly that happy, healthy employees do their best work. To that end, we offer:\n100% employee health insurance coverage (plus 50% dependent coverage)\n\nMonthly wellness, commuter, and educational stipends\n\n4 weeks PTO, plus holidays\n\nNYC office near Bryant Park, for those who want it. Remote-friendly by default.\n\n401(k) plan\n\nParental leave policy\n\nCompensation\nBase salary range of $170k-$225k, plus meaningful equity. Actual compensation depends on many factors, including relevant experience and skillset.\n\nAt this time, Luminary is unable to sponsor employment visas or provide immigration support.","description_format":"text","description_chars":6010,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Health insurance","Insurance coverage","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Wealth Management & Financial Advisors","Financial Software & Embedded Finance"],"lifecycle":[{"event":"open","at":"2026-08-17T15:35:22Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.546,"p_room":0.35,"age_days":59,"expected_fill_days":27,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":225000,"is_top_pay":true},"html_url":"https://alion.io/job/luminary-fm-software-engineer-backend","json_url":"https://alion.io/job/luminary-fm-software-engineer-backend.json","meta":{"generated_at":"2026-10-17T03:59:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":5212,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":36997},"rest":"https://alion.io/mcp/rest/get_company?id=36997"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fluminary-fm-software-engineer-backend"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fluminary-fm-software-engineer-backend"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fluminary-fm-software-engineer-backend"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/luminary-fm-software-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fluminary-fm-software-engineer-backend"}]}
