Cogent AI Fellowship (Member of Technical Staff)

About the role

Cogent Research is investing equally in two core research areas. The first is agentic security : as AI agents are deployed in production, real-world incidents have shown that prompt-level guardrails are insufficient. Agent behavior requires guarantees that are non-bypassable, AI-synthesized, and human-auditable. The second is auto-remediation : resolving security findings at machine speed in real customer environments. Each area is a first-class research objective, and the two are deeply connected. Auto-remediation can only operate safely at the required level of autonomy when agentic security guarantees are in place. Across both areas, we combine AI with formal methods: tool calls governed by runtime-enforced policies, and code fixes that ship with machine-checkable certificates of correctness. The Cogent AI Fellowship is an early-career research-engineering track for recently graduated, or soon-to-graduate, PhDs who want to move research from paper to production. Fellows choose a problem they are excited to pursue, prototype quickly alongside our research and engineering teams, and ship production systems. We look for people who are comfortable with ambiguity and willing to change direction when the evidence calls for it.
