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 national security enablement with agentic AI. Our platform tightens the loop from observation to action by giving warfighters cutting-edge analysis tools to make better decisions, faster.
We’re looking for a talented Product Engineer to join the Systems Agents engineering team. This team builds the coding harness, runtime layer, and software integrations to modernize mission-critical software systems, reduce technical debt, refactor legacy architectures, and accelerate software delivery using AI.
Your team will partner closely with customers, designers, product leaders, and forward-deployed engineers to build lasting products where our partners are meaningfully enabled by AI. You’ll be responsible for building novel full-stack agentic workflows that are production-grade, cybersecurity compliant, and have strong evaluations.
This role is ideal for a product-minded software engineer that has deep technical judgment around AI-native product development and can embed closely with a deployed engineering team to fuse product signal from the early prototyping phase into an enduring product vision. You’ll help the team move quickly, iterate with users, and build pragmatic, high-impact agentic systems for national security missions.
