Company Description – OleOle

“Where Fans Kick Off.”

OleOle is building the world’s first social network and messaging platform built entirely for football fans. Imagine a hybrid of Twitter, TikTok, WhatsApp, live scores, and WeChat->

We’re using Rust, AI, and the Solana blockchain to deliver real-time translated content, in-match crypto gambling, fan rewards, and a decentralized app marketplace for clubs, brands, and developers.

Our platform empowers over 3 billion football fans to join their club and country communities, share content, place bets, earn rewards, and interact with their favorite teams in any language—all without ads or middlemen.

OleOle is venture-backed, global, and rapidly expanding. We operate on deferred compensation until funding closes, with upside in equity and tokens for those who want to build the future of sports.

About the Role:

We’re seeking a hands-on Senior Front-End Developer to own the entire client-side stack, from architecture to pixel-perfect delivery, while seamlessly integrating with a Rust micro-services backend and a modern AWS-centric cloud environment. You’ll collaborate with product, design, and Rust backend engineers to deliver robust, elegant user experiences at scale.

Key Responsibilities:

• Build & Ship UI (40%): Design, develop, and maintain SPA/SSR front-end features using React (preferred) or comparable frameworks. Ensure performance, accessibility, and cross-browser support.
• Rust Integration (20%): Consume gRPC/REST/GraphQL APIs from Rust backends. Model complex data flows and optimize serialization (e.g., Protobuf, FlatBuffers, JSON).
• AWS Integration (15%): Connect front-end workflows to AWS services (Cognito, S3, CloudFront, API Gateway, AppSync/GraphQL, Amplify, Lambda). Automate deployments via CI/CD (GitHub Actions, CodeBuild, Amplify Hosting).
• Architecture & Code Quality (15%): Drive component design, state-management patterns, testing strategy (Jest/Vitest + RTL/Cypress), and code reviews.
• DevOps Collaboration (10%): Pair with DevOps to define IaC (CDK/Terraform) for front-end hosting, versioned artifacts, and blue-green/Canary deployments.

Must-Have Qualifications:

• 5+ years of professional front-end development with JavaScript/TypeScript ES6+.
• Deep expertise in React (or Vue/Angular with willingness to switch) and ecosystem (Hooks, Context, Redux/Zustand, RTK Query, Next.js or Remix for SSR).
• Demonstrated experience integrating with Rust backends (or other strongly-typed services) via REST, gRPC, or GraphQL.
• Solid grasp of AWS front-end workflows, including:
  • Cognito / Cognito Hosted UI for auth & SSO
  • API Gateway / AppSync for API orchestration
  • S3 + CloudFront for static asset delivery & edge caching
  • Amplify or CDK pipelines for CI/CD
• Proficiency with modern tooling: Vite/Webpack, ESLint/Prettier, Storybook, Playwright/Cypress, GitHub Flow.
• Strong UX sensibility: responsive design, WCAG-2.1 AA accessibility, Lighthouse/CLS performance budgets.
• Excellent communication and documentation skills; ability to explain complex topics to cross-functional audiences.

Solutions not problems .

• Creative problem solver who can courageously propose and support new ideas to our organization. Not interested in best practices, lets build something better!
• Ability to adapt. An ideal candidate will welcome the opportunity to solve a broad range of problems using a wide array of technologies.
• Comfortable with ambiguity, shifting priorities and general growing pains of an early-stage technology company
• An exceptional entrepreneurial judgment that fosters independence over micro-management
• Understanding of football and international sports a huge plus

Ole Ole is located in beautiful Austin Texas, however, this role requires some travel we are privately held and rapidly growing!
