Job description

About Us

We’re a digital entertainment company creating engaging online platforms people love. Since 2021, we’ve been building something different. Our brands include MetaWin, WOW Vegas, BetZoo Media, Hit.com and Rolla with more to come.

With teams operating from London, Malta, Gibraltar & Miami launching in 2025, each platform is designed to offer unique, engaging, and innovative digital experiences. From immersive betting platforms to exciting casino games and interactive online entertainment, our brands deliver cutting-edge technology and user-focused design.

Arena prioritises the use of innovative technology, decentralised where possible and builds with an AI first mindset to create the highest quality end product for our users. Not challenged by legacy systems, we are blue sky thinkers changing the landscape of digital entertainment.

Overview

We’re assembling a core engineering strike team of five dynamic, ambitious builders. This isn’t a corporate job, it’s an opportunity for ambitious engineers who want to create, ship, and evangelize world-class code at speed. These engineers will be the engine room of our product ecosystem: building full-stack applications, iterating fast, and helping shape the engineering culture around Claude-first AI coding practices.

Candidate Profile

• Experience: ~5 years professional coding, with a strong portfolio of shipped projects (startups, open source, or commercial).
• Mindset: Hungry, ambitious, thrive in high-intensity environments, comfortable wearing multiple hats.
• Claude Evangelists: You’ve already built a personal workflow around Anthropic’s Claude, using it daily to accelerate coding, refactor, debug, and design system architecture.
• Cultural Fit: Builder mentality, bias for action, thrives in chaos, obsessed with outcomes not process.

Technical Stack

• Core Languages: JavaScript / TypeScript (expert level).
• Frontend: React, Next.js, Tailwind, component libraries.
• Backend: Node.js, Express / NestJS, REST + GraphQL APIs.
• Databases: Postgres, MongoDB, Redis.
• DevOps: Docker, CI/CD pipelines, cloud platforms (AWS, GCP, or similar).
• Bonus: Web3 (Solidity, EVM, Sui, Solana), AI API integrations, real-time systems (WebSockets).

Responsibilities

• Design, build, and maintain full-stack applications with clean, scalable code.
• Move fast: prototype, iterate, and ship features in days, not months.
• Use and evangelize Claude-powered coding workflows across the team.
• Participate in system design, architecture discussions, and scaling strategies.
• Own features end-to-end: ideation → execution → deployment → monitoring.
• Mentor peers in best practices, especially around Claude-assisted development.
