About the role
We are looking for a Principal Frontend Engineer with 8-15 years of experience to serve as the technical authority and discipline lead for our web platform at Arena Club. You'll be a visionary architect who defines the long-term frontend strategy for a high-growth digital marketplace expanding into new collectible categories — currently scaling from 1.5 billion to 2.5 billion transactions per month. This is a role for mobile first web engineers who are deeply opinionated about system architecture and performance, and able to ensure our platform handles massive traffic spikes during drops, live auctions, and promotional events. You'll collaborate closely with product, marketing, and engineering leadership in a flat, low-ego environment where strong communicators thrive.
What will you be doing?
- Define and own the architectural vision for all Arena Club web applications, ensuring systems are modular, performant, and resilient at scale
- Lead the modernization of the frontend architecture — migrating monolith repos to microservices and building net-new category launches (new categories ship in 2-3 months)
- Design high-concurrency frontend systems that can handle a million+ users hitting the site within minutes during drops and promotional moments
- Set the standard for the frontend discipline — establishing patterns, build pipelines, and best practices across the engineering org
- Partner with product, marketing, and executive leadership to influence the roadmap and ensure technical debt is managed as the platform rapidly scales into new categories
