AI Security & Control Engineer

THE OPPORTUNITY We are building Watcher, a coding agent security product. We are looking for a security & control expert  to help us design better threat models and control protocols against AI adversaries, and improve the effectiveness and security of Watcher.  A security & control expert embedded in the product team with three functions:  Research: Supporting Apollo's monitoring research with threat modeling, attack design, red-teaming, and trajectory analysis (~50%), Expert view: Bring a security expert’s view of what security buyers need to make Watcher a better product (~25%),  Product security: Improve the security posture of Watcher and Apollo's product infrastructure (~25%).  This is truly a “start-up role” in the sense that you have many responsibilities and have significant say in shaping the direction of the role. This is an individual contributor role but could lead to management responsibilities eventually, if desired. ABOUT THE TEAM The Product / Control team is a new team. Especially early on, you will work closely with Marius Hobbhahn (CEO & currently leads the monitoring team), Victor Gillioz (Research Scientist), Monika Jotautaitė  (Research Scientist), and our product engineers: Jeremy Neiman,  Zak Walters, Zen van Riel, and Srdjan Miletic. Furthermore you will interact with our other SWEs and researchers, since we intend to be “our own customer” by using our products internally for our research work. You can find our full team here. ABOUT APOLLO RESEARCH The rapid rise in AI capabilities offer tremendous opportunities, but also present significant risks. At Apollo Research, we’re primarily concerned with risks from Loss of Control, i.e. risks coming from the model itself rather than e.g. humans misusing the AI. We’re particularly concerned with deceptive alignment / scheming, a phenomenon where a model appears to be aligned but is, in fact, misaligned and capable of evading human oversight. We work on the detection of scheming (e.g., building evaluations), the science of scheming (e.g., model organisms), and scheming mitigations (e.g., anti-scheming and control). We closely work with multiple frontier AI companies, e.g. to test their models before deployment or collaborate on scheming mitigations. At Apollo, we aim for a culture that emphasizes truth-seeking, being goal-oriented, giving and receiving constructive feedback, and being friendly and helpful. If you’re interested in more details about what it’s like working at Apollo, you can find more information here. We're now also developing tools and products (see Watcher) that make it easier to prevent harms from AI systems widely deployed AI systems.
