The listing
Vannevar builds AI systems for the Department of War's most consequential missions. We have 125 deployments across every branch and combatant command spanning our core platform and five distinct products. An an example of how we work, when major combat operations started with Iran, we fielded a new product supporting 24/7 operations and 9,000+ users in three months.
How we build is our advantage: we deploy forward with the people who own the mission. Our engineers, product team, and CTO deploy forward to the point of friction, including visiting units in Ukraine. We focus on embedding directly with operational units supporting great power competition with China, combat operations with Iran, and counter-narcotics missions.
About the role
Vannevar is seeking an experienced full-stack engineer to advance the design and implementation of our Decision Advantage product. This critical platform enables defense and intelligence operators to gain comprehensive situational awareness of the information environment, helping them understand and counter adversary influence operations and information warfare tactics. You will build the applications our warfighters and intelligence analysts use daily for mission-critical work, developing advanced products and features for information distillation, analysis, and visualization that enable rapid assessment of the information environment. Working alongside designers, engineers, subject matter experts, and operational users, you will transform complex intelligence requirements into intuitive, mission-ready workflows that directly support national security objectives.
In this role, you will work in a small cross-functional team focused on delivering Decision Advantage capabilities to defense customers engaged in strategic competition with near-peer adversaries. You will work on all aspects of the product - everything from data (extraction, ingestion), backend (storage, indexing, APIs), frontend, AI analysis (agents), and more. The platform has a strong foundation to build upon and there is a ton of opportunity to make an impact as we take it to the next level.
