Senior Fullstack Product Engineer
Location: Remote (US Shift- EST)
Type: Full-time Permanent Role
Company Name: Satschel Inc. (https://satschel.com/)
Company Products: https://liquidity.io/ , https://simplici.io/
Job Description:
Own the money. Every dollar accounted for.
Liquidity 2.0 is a regulated trading platform where investors onboard, fund their accounts, trade
stocks & crypto, and every trade settles on our own blockchain.
We're a small, AI-native engineering team building in full-stack TypeScript and shipping to real
production environments every week.

-TypeScript / Node.js
-PostgreSQL
-Brokerage APIs
-Banking & KYC Rails
-Webhooks

What You'll Own
-The features investors interact with every day: onboarding, wallets & funding, trading, and portfolio.
-The complete product stack—from polished React/Next.js frontends to clean Node.js APIs and
well-designed data models.
-The product experience, ensuring every loading, error, and edge state is handled with care. Screens
displaying balances, prices, and orders must never show incorrect information.
-A fast-paced development cycle where ideas move from concept to production in days, not
Quarters
What We're Looking For
-7+ years preferred (5+ years minimum) of hands-on experience building production web
applications with TypeScript as your primary language. This is a builder role, not a manager role.
-Deep expertise in React and Next.js, including SSR, data-fetching patterns, state management, and performance profiling.
-Strong backend fundamentals, including designing REST APIs with Node.js, authentication flows,
input validation, and consistent error handling.
-Solid SQL knowledge with experience in PostgreSQL schema design, indexing, migrations, and
working with ORMs.
-Testing as a habit—you write unit and integration tests without being asked.
-A strong eye for UI and the ability to build polished, production-ready interfaces using a design
system.
-AI fluency with engineering rigor. You should be a daily user of AI coding tools like Claude Code and
Cursor while consistently validating AI-generated code.
-Clear written communication skills—we work async-first across time zones.
Bonus Points
-Experience with fintech or trading platform UX.
-Experience with Prisma, Redis, and pnpm monorepos.
-You've shipped a product end-to-end that you're proud to showcase
