Software Engineer
Senior Fullstack Engineer building AI-driven defense platforms, developing scalable web applications with Python, React, and Node.js, deploying on AWS and Kubernetes, and integrating machine learning models to simulate adversary behavior and support decision‑making.
Vannevar is a defense technology company building AI to deter our adversaries. In the 21st century, conflict moves at algorithmic speed and foresight equals firepower. Our agentic AI is purpose-built to compete with China—from cross-Strait conflict to gray zone coercion. Trained on the most mission-relevant datasets in defense, our technology models adversary behavior, simulates campaigns, and recommends the best course of action to decision makers. Our AI systems are some of the most trusted in the industry and actively used on the front lines of the Indo-Pacific to keep the peace and save lives.
Exceptional technology starts with exceptional people. Vannevar is a small agile team combining world-class engineers with veteran strategists who bring deep expertise in defense and tradecraft. We’re building a company defined by mission impact, user empathy, and disciplined growth. In just three years, we grew from $3M to $80M in ARR, achieved early profitability, and reached unicorn status—proving that disruption doesn’t require an ego, and staying power doesn’t mean standing still.
About the role
Vannevar is building the future of nation security enablement with agentic AI. Our platform is responsible for tightening the loop from observation to action - providing the warfighter with cutting-edge analysis tools to make better decisions, faster.
We are searching for an experienced product engineer who has previously helped shape agentic AI technology.
