Neptune is building the concierge couples trust to navigate the biggest decisions of a life together. We pair emotionally intelligent AI with vetted legal and financial experts and transparent pricing, so both partners can make confident, fair decisions together and build a life - and lasting wealth - as a team.
At the center is a shared operating system for couples that remembers everything for you, so you never repeat yourself and every next decision starts from what we already know. Couples make billions of dollars in financial and legal decisions over a life together, and no one has built the trusted companion that carries the full picture across all of them. That's the category we're defining, and it's a rare moment to help build it from the ground up.
We (Ex-Stripe, Google, Palantir, Uber) have raised $7.5M from Floodgate (Lyft, X, Twitch) and The General Partnership, and demand is growing fast. We're hiring our first founding engineer to build the product every couple will trust with their most important decisions.
Compensation: $175K–$250K base, plus meaningful founding-level equity.
Real ownership: You're employee #1 on engineering working directly with our CTO. You'll own large parts of the product and the technical direction.
Impactful work: Build with LLMs on a real use case with product-market fit, on a small team where your work ships and reaches users every week.
You'll be turning something emotionally fraught, legally complex, and deeply personal, a conversation most couples avoid entirely, into a product people actually trust and enjoy using. You'll design conversational AI that handles sensitive financial and emotional context with care, wire LLMs into real legal and financial workflows, and make outputs that have to be not just correct but have high credibility and trust to act on.
You'll own features end-to-end (architecture, frontend, backend, deployment), and your decisions will set the technical foundation for everything Neptune becomes.
The product, end to end. Design and ship experiences that make life's biggest financial and legal decisions feel accessible and empowering. You own features from architecture through deployment.
AI at the core. Build the conversational AI and LLM-powered workflows that are the heart of Neptune. Turn model outputs into experiences couples can trust with real money.
The Neptune brain. Build the shared memory and context engine at the heart of the product, the system that remembers each couple's full financial and legal life and makes every next decision smarter.
You'll work directly with the founding team (former Google, Stripe, Palantir, Uber, Thirty Madison) and talk to real users every week, watching what you ship change how couples make their most consequential decisions. Work is organized around the problem it solves, not where it sits in the stack.
An AI-native engineer. You use AI coding tools as a genuine force multiplier and you have real intuition for how foundation models perform across different tasks.
A high-agency builder. You take initiative, drive projects to done, and adapt fast when priorities shift. You've built something real that people actually used or paid for.
A full-stack engineer with 3–6 years of experience and a track record of shipping impactful features into production. You can architect a backend and craft a frontend, and you think in product (UX, user value, workflows).
Comfortable with ambiguity and energized by hard problems in a high-trust domain.
A clear communicator. You'll talk directly with users to get feedback and make sure the product genuinely delights them.
Experience with our stack: React, TypeScript, TanStack, Go. We care more that you ship well than that you've used exactly these.
Familiarity with fintech / financial-data platforms.
Prior founding engineer experience, or having taken large ownership in a startup environment.
Ownership and autonomy: each project solves a concrete problem, and you own it end-to-end.
User obsession: you'll talk to users directly and build for what they actually need.
Fast iteration: weekly check-ins, problems over process, and a bias toward shipping.
New York City: we're in the office together five days a week.

Know your rights as a candidate and an employee:
The job is in New York, NY. Below is what the official statistics say about living and working there.
How New York compares. Among the 120 largest places in New York, New York is #1 by population, #117 for homeownership (#1 = highest), #115 for long commutes (#1 = fewest), #31 for remote work (#1 = most). Its county, Kings County, is #38 of 62 counties for average pay ($59,980).
New York has 8,483,844 residents (ACS 2020–2024), about 42.7% of the population of New York. It covers 300 square miles of land, which works out to roughly 28,236 people per square mile. The median age is 38.2, 4% younger than the state median (38.2 against 39.8).
The median gross rent is $1,821 a month (rent plus utilities), 12% above the state median ($1,821 against $1,621). Over a year that is 27.2% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $777,600, which is 9.7 times the median household income ($80,483); a ratio above 5 usually means buying is out of reach without savings or a second income. 32.8% of households own their home, 40% below the state average (32.8% against 54.4%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.
The New York-Newark-Jersey City, NY-NJ metropolitan area has 9,492,000 jobs in the BLS wage survey, and the median pay across all occupations is $61,430 a year, 20% above the national median ($61,430 against $50,980). The biggest occupation groups are office and administrative support (1,109,360 jobs, median $55,080); healthcare support (843,730 jobs, median $40,100); sales and related (751,110 jobs, median $47,540). The area is most specialised in healthcare support (1.8 times) and legal (1.7 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($171,990) and legal ($150,990). In 2026M09 the unemployment rate of Kings County was 5.3%. 63.1% of residents aged 16 and over are in the labour force. The city lies in Kings County; its jobs, pay by industry and GDP are on the county page.
Among workers, 21.6% drive alone, 44.0% use public transit, 9.2% walk, 16.9% work from home. 41.2% of workers commute 45 minutes or more, 50% above the state average (41.2% against 27.4%).
41.6% of adults aged 25 and over hold a bachelor's degree or higher, 4% above the state share (41.6% against 40.2%). 36.6% of residents were born outside the United States, 61% above the state share (36.6% against 22.8%). The poverty rate is 17.9%, 28% above the state rate (17.9% against 14.0%).
The warmest month is Jul, averaging 75°F (23.7°C), and the coolest is Jan at 34°F (1.1°C). About 1,313 mm (52 inches) of precipitation falls in a year; Dec is the wettest month (133 mm) and Feb the driest (95 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
Closest cities in this guide: Hoboken (7 miles, rent 61% higher); Jersey City (7 miles, rent 10% higher); Union City (9 miles, rent 16% lower); Bayonne (9 miles, rent 8% lower). Rent differences are against New York; use the Compare tab to put any two cities side by side.
