Senior DevOps Engineer

Arena Club is building the number one digital marketplace for collectibles. We started by reinventing the hobby with the first-ever digital card show, and we are expanding into new categories so collectors can buy, sell, grade, and showcase everything they care about in one place. Our ‘Slab Pack’ product brought the mystery and chase of opening physical packs of cards to a digital format, and has led to Arena Club being one of the fastest-growing (and highly profitable) companies in Los Angeles. Our business was founded by 5x World Series Champion Derek Jeter and serial entrepreneur Brian Lee, who previously founded LegalZoom and The Honest Company, both of which are now public companies.

We’re seeking a Senior DevOps Engineer to design, build, and operate the infrastructure, deployment systems, and operational tooling that support Arena Club’s platform.

As a trusted partner to engineering and product teams, you will help enable fast, safe, and resilient product delivery in a fast-paced environment where your work directly impacts system uptime, performance, and overall platform health.
