Own the heart of the exchange—the matching engine.
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.
-Tech Stack
-TypeScript / Node.js
-Matching Engine
-Order Books
-Market Data
-Event Streams
-Deterministic Systems
What You'll Own
-The matching engine—the core system that pairs every buy and sell order on the exchange.
-Order books, order types, and execution semantics, including market orders, limit orders, time-in-force, and partial fills.
-Real-time market data, including prices, charts, order book depth, and trade feeds.
-Execution systems investors can trust—deterministic, fair, and thoroughly tested.
What We're Looking For
-7+ years preferred (5+ years minimum) of hands-on backend engineering experience in systems where both performance and correctness are critical. ----This is a builder role, not a manager role.
-Strong expertise in TypeScript/Node.js, or a deep systems programming background in Go, Rust, Java, or C++ with the willingness to work in TypeScript.
-Solid understanding of exchange mechanics, including order books, matching rules, price-time priority, and slippage.
-Experience designing concurrent and deterministic systems, including event ordering, sequencing, idempotent replay, and single-writer architectures.
-Experience building real-time data pipelines with streams, pub/sub systems, and backpressure handling.
-Strong testing mindset with simulation and property-based testing of execution logic—not just example-based testing.
-Numerical precision and experience handling financial calculations without floating-point errors.
-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.
Bonus Points
-Experience building exchange platforms, trading venues, or market-making systems.
-Strong understanding of market microstructure.
-Performance tuning experience in high-throughput systems.
