Job description

At Fun, we're building the financial infrastructure for internet capital markets.

The systems that power global finance were designed for a different era: slower, fragmented, and constrained by borders. Today, value is digital, global, and moves instantly, but the experience of moving it hasn't caught up.

Fun offers the highest converting payment solution in the digital asset space - a unified system that enables users to complete any on-chain action using crypto, exchange balances, or fiat from a card or bank account, all in a single, seamless flow.

Our goal is simple: make transacting with any asset feel effortless, anywhere in the world.

About the Role

We're looking for a BackEnd Engineer to join our growing team at Fun and help architect the backend services that power our web3 payments infrastructure. This role is foundational to the success of our platform and will shape how payments, settlement, and transaction routing are handled across chains and payment providers. You'll be working on high-performance, low-latency systems that support complex use cases like asset conversion, identity and security verification, transaction finality, and decentralized routing - while ensuring fault tolerance, scalability, and compliance across a global user base.

Location: Midtown, New York, NY (In-office Mon-Thurs, Remote Fridays). Team: Payments Infrastructure - Mid, Senior, Staff, or Principal Levels.

Responsibilities

• Design, build, and maintain high-performance APIs and backend services that power our Web3 payments platform
• Build new features to further our product experience
• Collaborate with product and protocol teams to architect technical solutions that meet business requirements
• Write clean, well-tested code and participate in code reviews to maintain high engineering standards
• Contribute to incident response and debugging production issues to ensure system reliability

Requirements

• Strong experience building production backend systems with modern languages
• Proficiency in Typescript
• Deep understanding of distributed systems, APIs, and database design principles
• Hands-on experience with cloud platforms and containerization technologies
• Solid grasp of computer science fundamentals including data structures and algorithms
• Strong problem-solving skills with ability to debug complex technical issues
• Clear communicator who can collaborate effectively with cross-functional teams

Nice to Have (But Not Required)

• Production TypeScript experience
• Previously worked at crypto startup or Web3 infrastructure company
• Experience with blockchain integrations, smart contracts, or DeFi protocols
• Background with high-scale payment processing or financial compliance systems
• Contributions to open source projects or technical writing
• Experience with event-driven architectures and real-time data processing

Why Join Us

• Shape the future of payments and programmable money
• Work with bleeding-edge tech in a domain where innovation moves fast
• Join a mission-driven team focused on access, openness, and trust
• Be a key contributor, not just a cog—your work will ship fast and matter
• Collaborate with top-tier protocols, builders, and financial infrastructure providers
