About Coinflow
Coinflow is a next-generation payments company headquartered in Chicago, pioneering the way money moves globally. We enable merchants and marketplaces to accept payment methods across 170+ countries with instant settlement, AI-driven fraud prevention, and blockchain-based proof-of-delivery.
Backed by leading investors—including Pantera Capital, CMT Digital, Coinbase Ventures, Jump Capital, and Reciprocal Ventures—Coinflow recently raised a $25M Series A to accelerate our mission to modernize cross-border payments.
Since our seed round in 2024, we’ve achieved 23x revenue growth and scaled to a multi-billion-dollar annual transaction volume run rate!
About The Role
We're looking for a Senior Software Engineer to help build the core infrastructure powering global payments. You'll design and implement systems that process billions of dollars in transactions, working across our payment orchestration layer, merchant APIs, and real-time settlement engine.
This is a high-impact role where your code ships to production quickly and handles real money from day one. You'll collaborate closely with Product to shape what we build, with fellow engineers on how we build it, and have significant ownership over the systems you create.
What You'll Do
Build Core Payment Infrastructure
Join the team rewriting how money moves worldwide—and become a driving force in the $194 trillion cross-border payments market.

What does a React developer in web3 do?
A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain
These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network
Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain
As a React developer in web3, some of your responsibilities might include:
- Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
- Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
- Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
- Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
