A high-growth team building core infrastructure for crypto payments is hiring a backend engineer to help scale the next generation of on-chain commerce. The product enables any dApp to accept crypto or fiat with seamless UX - bridging wallets, exchanges, and banks into one high-converting flow.

• architecting backend that powers their checkout engine + crypto SKD integrations

what they’re looking for

• 4+ years backend experience (node.js and typescript preferred)
• strong with infra - networking (tcp/ip, dns, load balancing), databases (mysql, postgres, dynamodb), iac tools like terraform, cloudformation, or aws cdk
• experience with monitoring/logging tools like prometheus, grafana, cloudwatch, elk, or splunk
• smart contract awareness - ability to write, test, and debug them is a plus
• familiarity with defi protocols, nft standards, or web3 developer tooling
• solid testing practices and an eye for performance, security, and fault tolerance

what'll make you stand out

• been promoted quickly at a strong company - FAANG, Stripe, Coinbase, Kraken etc
• contributed to open source or have a strong github - lot of green squares!
• worked at a payments, infra, or crypto startup
• built backend systems that had to scale and stay up under pressure
• come from a top-tier university - MIT, Stanford, CMU, Berkeley etc

why you should apply

• work on systems that actually ship and scale
• high-caliber team, tight feedback loops, strong engineering culture
• hybrid NYC setup - mon–thurs in-office, fridays remote
• real product-market fit, real adoption, and plenty left to build

please apply today if the above sounds like you.
