About Arena Intelligence

Arena is the platform for evaluating how AI models perform in the real world. Founded by researchers from UC Berkeley's SkyLab, we're on a mission to measure and advance the frontier of AI for real-world use, and to build the foundation for everyone to understand, shape, and benefit from it.

Tens of millions of people use Arena each month to evaluate how frontier systems handle the work they actually do. The preferences they share power the most transparent, rigorous, and human-centered evaluations in AI. Leading AI labs, enterprises, and independent researchers rely on our work and open datasets to understand how models behave in real workflows: agentic coding, creative generation, professional productivity, and beyond. We go beyond leaderboards and decompose what human experience reveals about AI, so models advance toward the work people actually do.

We're a team of researchers, academics, builders, and creatives from UC Berkeley, Google, Stanford, and DeepMind. We seek truth, move fast, and value craftsmanship, curiosity, and impact over hierarchy. We're building a company where thoughtful, curious people from all backgrounds can do their best work together, in an office culture that radiates excellence, energy, and focus.

About the Role

We are looking for a senior IT and security engineer to own that function's technical
direction. You will set how identity, endpoints, and access actually work here, decide what gets automated rather than done by hand, and be the person the team defers to on the hard calls.

This is a hands-on seat. You will do the work, not direct it from a distance.

You are not starting from zero. Identity is centralized with automated provisioning, the fleet is managed and enrolled with endpoint protection deployed, and remote access runs through a zero-trust layer. The foundations work. We need someone to deepen them, extend the model to areas it doesn't reach yet, and document what currently lives in people's heads.

The scope goes past enterprise systems. Our engineers build on source control, cloud data and analytics platforms, hosting, and managed infrastructure, and access to those carries
consequences that a wiki or a calendar does not. You will own how entitlement works there too.

This role is onsite in our San Francisco office.

You'll

• Design the identity and access model, not just administer it. Okta is the center of gravity: SSO and SCIM, group and role design, lifecycle automation for joiners, movers, and leavers, and access reviews that produce evidence an auditor accepts. You decide what determines group membership and what the source of truth is.
