About Security Level 5

Security Level 5 is a Bay Area AI security nonprofit working with AI labs and US intelligence agencies to defend frontier models from priority nation-state-level threats. We move fast, and we're tripling headcount this year.

The Mission

We're hiring for what's plausibly the most difficult, urgent, and interesting challenge in AI security engineering this decade (for humans, at least): designing and building the first datacenter purpose-built to Security Level 5, the standard for defending frontier AI labs against attackers with the resources of a nation-state and billion-dollar budgets. We're working on the first SL5 components this year and aiming for an at-scale SL5 datacenter build in 2027.

We wrote the first version of the standard with input from CISOs and senior security staff at the frontier labs, and US security and intelligence officials. Now we're designing the SL5 architectures purpose-built for frontier AI workloads, and standing up the reference tech stack to guide labs' buildouts. This stack has to hold against nation-states, not destroy researchers' productivity, not cost more than labs can pay, and ship in 2-3 years.

What you’d work on

Managing the CEO’s Calendar and Communications

Helping with admin tasks such as expenses, booking trips, making appointments, etc

Meeting support: helping polish and prep documents, slide decks, etc

Proof reading & drafting short bits of writing for the CEO, eg on emails or outreach tasks

Helping prioritise tasks / keep an eye out for ‘dropped balls’ on slack/email/task trackers

You'd be a fit if you

Take pride in being exceptionally detail oriented and conscientious in all your work.

Stay unflappable when priorities change fast, and can hold many moving pieces without dropping any.

Treat confidentiality as second nature and are at ease supporting an organization working on sensitive national-security-adjacent material

Are proactive and low-ego — you spot the thing that needs doing and do it, rather than waiting to be asked

Are exceptionally organized and calm under a shifting schedule, including complex multi-timezone and international travel

Communicate crisply in writing and can draft in someone else's voice

Thrive in an early-stage, build-it-as-we-go environment and are comfortable with ambiguity and standing up new processes

Are technically fluent enough to work in modern tools (calendar, docs, expense, project, and communication platforms) and to pick up new ones quickly

Care about the mission and want your operational work to compound into something that matters

Logistics

Bay Area, in-person. This role's base salary range is $80,000 - $130,000 USD per year. We are open to part-time (paid on a per-hour basis) or remote setups are possible for this role. Part-time or remote agreements may have different compensation than the above. We may be open to paying exceptional and/or highly experienced employees more than this. For full time roles, we will provide full benefits, including healthcare, dental, vision, 401k match, and more.
