PRODUCT ENGINEER
Singapore (On-Site) | 2–4 Vacancies
Compensation: SGD 120,000 – 220,000 + Equity
Our client is a Series A Web3 payments infrastructure company that makes onchain value transfer intuitive, secure, and seamless for everyday users and developers. Their flagship product is a high-conversion payment solution that allows users to complete any onchain action using assets from self-custodial wallets, centralized exchanges, or fiat on-ramped from cards and bank accounts. By aggregating routing and exposing users’ full asset portfolios at the point of sale, the product helps decentralized applications drive faster, stickier, and more engaged users without stitching together multiple providers or spinning up new chains.
The company has processed over USD 1.3 billion in payments in the past 30 days alone, annualizing to over USD 12 billion – growing from effectively zero just a year and a half ago. Notable clients include leading prediction markets, DeFi protocols, and consumer-facing crypto platforms. They have recently closed a funding round, have multiple years of runway, and are actively scaling.
The company currently has ~30 team members globally and is expanding its Singapore office from 2 to 10 engineers by end of year. This is a unique opportunity to be part of the foundational Singapore team and help shape the company’s Asia-Pacific engineering presence.
Product Engineers design and scale the SDKs and product surfaces that power the company’s Checkout experience across web2 and web3 environments. This team owns user-facing flows and developer integrations, balancing performance, reliability, and UX for dApps and financial platforms integrating crypto payments. You will work directly with protocol and backend teams to solve technically complex, product-centric problems for onchain payments at scale.
This is an on-site role in Singapore, four days per week (Mon–Thu), with flexible Fridays (WFH optional). The company will support relocation for the right candidates, including Employment Pass (EP) sponsorship.
