Senior Software Engineer – FedRAMP ATO Location: San Diego, California, United States Compensation: $150,000 - 215,000 USD / year About the Role 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. At Vannevar we're consistently iterating on AI‑enabled software products to deter our adversaries and lead the fight for strategic competition. This often involves meeting our customers where they're at – on government networks, higher classification systems, and bespoke deployments. Compliance and security are core principles in how we build software to support the warfighter.
