Human security for the AI era. Adaptive unifies security awareness training, phishing simulations, agentic email security, and AI governance. Backed by a16z.
About the role
Define Adaptive's ML strategy: where ML should be applied across our products, what infrastructure we need, and how we should approach build vs. buy decisions. Design and build production ML systems end-to-end — data pipelines, model training, evaluation frameworks, and inference serving.
What they're looking for
- 4+ years of experience building ML systems in production, ideally with experience standing up the ML function at an early stage startup or as the senior or lead ML person at a previous company
- Strong software engineering fundamentals. You write production-quality code in modern languages (Python, Java, TypeScript) and work within large codebases
- Experience with cloud ML infrastructure (AWS SageMaker, Bedrock, Modal, Baseten, or similar)
- Experience with common ML and data processing frameworks (PyTorch, Tensorflow, Spark)
- Comfortable working across the stack — infrastructure, backend services, and data systems
- High autonomy. You'll have support and context from leadership, but you're expected to define the path forward and drive it
More about this role
NVIDIA and OpenAI’s only AI cybersecurity investment.
Adaptive is a cybersecurity startup on a mission to stop AI-powered cyberattacks. In December 2025, the company announced an $81M Series B led by NVIDIA and Bain Capital Ventures, with participation from Capital One Ventures, Citi Ventures, and continued support from Andreessen Horowitz (a16z), the OpenAI Startup Fund, and Abstract Ventures. The round marked NVIDIA’s first AI cybersecurity investment.
Adaptive was founded by Brian Long and Andrew Jones, repeat entrepreneurs who have built and scaled category-defining companies. Brian and Andrew previously co-founded Attentive, which grew to more than $500M in annual revenue and a $10B+ valuation, and TapCommerce, which was acquired by Twitter. Together, they bring deep experience building high-growth, product-led businesses at massive scale as Adaptive builds the security layer for the AI era.
Trusted by leading banks, technology companies, and healthcare organizations, Adaptive protects teams from emerging threats like deepfakes, smishing, and AI-powered voice scams. With rapid enterprise adoption and a $200B+ market ahead, the company is just getting started.
