From football content to commerce, ticketing, gaming, NFTs, and crypto betting — we’re building a super app for sports. This is a once-in-a-lifetime opportunity to be a founding engineer at a startup aiming to reshape how sports communities engage digitally — from the Champions League to the World Cup. **What we do...** oleolesport.com empowers people to identify football experience and without any search requirements, simply presents the traveler with vetted components necessary to bring the trip to life -- tickets, lodging, flights and beyond. And we are building a football super app. **Why we are better...** oleolesport.com’s searchless travel approach means a soccer/football experience can be discovered, planned and purchased in a matter of minutes without the endless search-driven lunacy and inefficiency that comes with all travel planning. There isn't a sports social network; oh some claim to be, however they lack even the slightest understanding of network platforms. ## Job Description **What We’re Looking For** ### About the Role We’re looking for an experienced Rust developer to join our core engineering team building high-performance backend services.
