Security Engineer (Corporate IT)

About this role

## About Sequent

Sequent does research on how to align artificial superintelligence (ASI). ASI may be developed in the next few years, but it is unclear whether alignment is on track to be ready in the same timeframe. We aim at higher *a priori* confidence in aligned outcomes by pursuing a portfolio of theory and empirics bets, any one of which — if it succeeds — would meaningfully advance the field. We invest heavily in research automation to accelerate progress, and we believe that stronger alignment theory unlocks higher automation: more principled approaches give us better filters for which directions of automated research are promising.

Sequent was founded in May 2026 by researchers from UK AISI's Alignment Team, who ran the £30m Alignment Project, and Timaeus, who pioneered applying singular learning theory to alignment.

## About the Role

We are looking for a hands-on, strategic leader to build and own our Corporate IT and Security function from the ground up. As we scale from our current team to 40 to 60 FTEs over the next two years, you will be the single point of accountability for ensuring our researchers have the tools they need to move fast while maintaining a security posture that earns the trust of external partners and AI labs.

We are looking for a builder, not just a manager. You should be comfortable getting into the weeds of configuration and implementation, but you understand that your ultimate goal is to enable world-class research through secure infrastructure.

Sequent's work will involve sensitive frontier-relevant research and partnerships with AI labs. This role exists both to protect that work and to *enable* it: good security is what makes deeper lab partnerships possible. We draw a distinction between two closely related areas of security:

• **Research & infrastructure security****.** Securing how research actually runs: CI/CD pipelines, automated research agents, multi-cloud comp...
