Description About Tenzai Tenzai is building autonomous AI hackers that think like the world's best offensive security experts, act like them, and then help fix what they find before the real ones do. If this mission speaks to you, come defend the world's software: autonomously, continuously, and in-depth.

Your work will be deployed and used to hack into applications and systems in the real world. Responsibilites • Design and implement reinforcement learning workflows to train state-of- the-art LLMs specializing in cybersecurity. Design tasks, datasets, and benchmarks for training and evaluating LLMs and agents. • Work on experimentation and evaluation systems — evals are key to everything we do. In this role, you will build evaluation pipelines, design and build experiments, and construct simulations. Requirements • Strong understanding of modern LLMs, including training, post-training, RL, fine-tuning, and inference, with hands-on experience deploying LLM-based systems in production. • Hands-on experience building an agent, including working with complex loops, context engineering, and long-execution tooling. • 5+ years of hands-on programming experience in Python or other backend languages.

Why Tenzai • Working on problems that matter - Software is now written and deployed faster than it can be secured. Attackers are beginning to use AI to find vulnerabilities at scale. Tenzai exists to close that gap. It's a mission that requires elite hackers, and also sharp storytellers, wicked-smart operators, and experienced market builders. • Building a category in the making - Tenzai is defining a new category in cybersecurity. That means every team — from research and engineering to product, brand, and go-to-market — has a chance to shape how the industry understands and adopts autonomous security. If you thrive building something from zero and helping a new idea take hold in the world, keep reading. • Talent density - We believe small teams of exceptional people outperform large organizations. Tenzai was founded by veteran security experts and repeat entrepreneurs. We hire deliberately and value curiosity, initiative, and craftsmanship, whatever your discipline. • Creating real impact, quickly - Whether you're building systems, shaping product experiences, telling the story, or helping customers succeed, your work will immediately influence how organizations secure their software. We move quickly, keep teams lean, and give humans ownership. • Ambition with humility - We're tackling hard problems with a team that values deep expertise and thoughtful collaboration. Everyone here is learning, experimenting, and pushing the boundaries of what's possible. Plus, we love eating lunch together.
