Senior Applied ML Research Engineer, Agentic Security

About Dynamo AI

Dynamo AI is building the future of trustworthy AI for the enterprise. Our platform provides real-time guardrails, red-teaming, and observability for generative AI systems-ensuring safe, compliant, and reliable deployments across regulated sectors such as financial services, insurance, healthcare and government.

We’re backed by leading partners and rapidly expanding with some of the world’s most sophisticated enterprises. Our products are in production at some of the largest institutions in the world (including Intel, Lenovo, Experian, and the US Army), actively unlocking AI deployments. We're well recognized and well funded (>$30M raised), with offices in NYC, SF, and a European office planned to open soon.

The Applied Research Team builds zero-to-one security capabilities with fast iteration cycles. We live at the boundary between research and product: inventing what "agentic security" should mean, proving it through experiments, and turning it into systems customers can rely on.

Right now, we're building Agent Warden

a security layer that finds systematic attack patterns in agentic systems, localizes risk through static and dynamic analysis, and turns that into surgical, automated defenses.

About the Role

You'll help define an emerging area

how to find and neutralize the security risks that emerge when agents act, plan, and use tools autonomously.

This role is research-heavy and engineering-heavy

you'll design experiments, build prototypes, fine-tune models, and pressure-test systems against adversarial behavior. You'll iterate quickly, learn from failures, and scale what works, while building the monitoring and evaluation infrastructure that makes progress measurable. You can see what we're building here.

In this role you will

• Define and validate threat models for agentic systems, identifying which tool characteristics must co-exist to enable data exfiltration and malicious state change, and how to break those combinations
• Design and run experiments: create synthetic environments like file systems and tools, create task distributions that have attack paths and apply different attack strategies
• Break (manually and using optimization algorithms such as RL) agentic systems in
• Design and improve static and dynamic analysis methods that automatically map tool capabilities to risk across diverse tool ecosystems, and make those methods scale
• Turn research insights into product-facing capabilities: risk classification, automated guardrail generation, and quantitative threat measurement
• Build measurement tools: eval harnesses, monitoring, dashboards, and feedback loops that quantify security outcomes
• Build capability and regression evals
• Optimize systems for real-world constraints (latency, cost, reliability) without losing scientific rigor

You might thrive in this role if

• You have an MS or PhD in CS/ML (or equivalent research experience) and enjoy working under uncertainty
• You've fine-tuned and evaluated models in practice and can reason about data quality, overfitting, evals, and deployment constraints
• You can write strong production code, and you're comfortable owning the infrastructure that makes agentic evals run end-to-end. You care about reproducibility and instrumentation. No AI slop.
• You're motivated by security problems and enjoy thinking like both builder and attacker
• You reason about how capabilities combine into risk: not just individual vulnerabilities, but system-level attack surfaces across tool ecosystems
• You communicate clearly, iterate fast, and can hold a technical narrative from "hypothesis" to "shipped"
