Containerization for goods. SWIFT for money. Stripe for payments. Compliance is one of the last and largest — and the hardest, because trade rules aren&#39;t data to be looked up. They&#39;re a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.</p>\n<p><strong>THE ROLE</strong></p>\n<p>CX has an unusually high importance in a product like Sphere. Trust is of utmost importance when handling a company&#39;s payments and tax obligations. As a result, every user experience, modal, button, export needs to be flawless (would you trust Stripe with your payments if it was full of bugs and inconsistencies?).</p>\n<p>Sphere is looking for a passionate founding product engineer to own our CX, take it to the next level and help build out new features / products on our roadmap.</p>\n<p><strong>WHAT YOU&#39;LL DO</strong></p>\n<p>Within weeks:</p>\n<ul>\n<li>Work / listen to many of our customers on what their main pain points are and prioritize lowest hanging fruit features that can help solve their problems</li>\n</ul>\n<ul>\n<li>Collaborate extensively with design on bringing those features to life</li>\n</ul>\n<ul>\n<li>Executing and shipping features, end-to-end, on a daily basis</li>\n</ul>\n<ul>\n<li>Doing customer support where necessary to understand our customers and how they think as much as possible</li>\n</ul>\n<p>Within months:</p>\n<ul>\n<li>Own Sphere&#39;s CX and make it unique</li>\n</ul>\n<ul>\n<li>Own feature / product roadmap in conjunction with the CEO / Founder (you will work a lot together)</li>\n</ul>\n<ul>\n<li>Build / implement more rigorous customer feedback / analysis processes to allow us to better prioritize roadmap</li>\n</ul>\n<p><strong>REQUIREMENTS</strong></p>\n<ul>\n<li>Strong experience with React.
