Job Description

⛵️ About Wholesail Wholesale trade, a $55T global market, still operates like the world before the internet and modern payment networks; collection processes are manual and run on paper, short-term credit risk is assumed by the vendor, and businesses rely heavily on legacy ERP systems that don’t talk to each other. The result is large, measurable drag: we estimate that vendors spend over $500B a year on an inefficient mix of processing, bad debt, lending, credit insurance, software, and labor costs to get paid. Wholesail is building a financial network from the ground up that connects the systems of vendors and buyers involved in wholesale trade to enable streamlined payment and the transfer of risk to third parties. This will allow vendors to offload risk and eliminate tens of billions of waste—while giving creditworthy buyers better terms and third-party capital, unlocking hundreds of billions (ultimately trillions) in additional sales. The primitives of this network scale across industries and geographies: universal ERP integrations, modern payment rails, and a live trade-credit bureau to underwrite risk–which we’re calling Lighthouse . 🛠 About the Role As Wholesail’s second frontend engineer, you’ll play a critical role in crafting the core user experience that delivers value to the suppliers and buyers on our network. Your work will be primarily focused on the frontend, where you'll build intuitive and performant user interfaces using React. You’ll also make full stack contributions to our Node.js-based systems, such as helping to evolve our notification engine and other backend services that support user-facing features. You’ll also spend time with our sales and support team and our customers to figure out the details of the products you craft. Our small product team wears many hats, so you'll get significant exposure to many areas adjacent to engineering: design, marketing, customer success, sales, and all of the functions of an early stage startup. As a product oriented member of our engineering team, you’ll couple strong technical execution with an active voice in shaping the product through contribution in product conversations and identifying product/technical tradeoffs. You’ll participate in different styles of execution based on the stage of product development – from iterating quickly on an experiment with intentionally scrappy code to investing in frontend tooling and end-to-end testing infrastructure that increases our team's confidence and velocity over time. Most significantly, you'll be building the company with us. We are early on our voyage and there are vast uncharted seas ahead. We want to work with fellow Wholesailers who care deeply about the process of building an enduring company: from what values we embrace, how we build our teams, decisions about how we grow our business, and everything in between. 🚀 You’d be great a great fit for our voyage if you… Are naturally curious about and have a keen interest in understanding the "why?" by digging into the nuts-and-bolts of how things work as a first principles thinker. Think deeply about products – from building empathy for users, to understanding how a product works, how it fits into a complex system, and how it creates business value. Obsess about the details of your craft whether it’s designing a new abstraction layer, building an API for a colleague on the frontend team or shipping a pixel perfect feature. Quickly build intuition in new domains and are able to articulate product/engineering tradeoffs early on while also pragmatically handling (and minimizing work on) edge cases. Estimate and prioritize when faced with different proposed solutions, to help guide the team towards building the most impactful products. Strive to quickly deliver value through rapid product validation cycles and have a keen ability to identify quick wins that create value for customers.
