About the role

Vannevar's standard text

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.

What we’re looking for

  • Recent experience and excitement for building with Agent frameworks like LangGraph, Claude SDK, Google ADK, or similar.
  • Advanced software engineering skills, including experience with distributed systems, APIs, and cloud infrastructure
  • A history of not only building great tooling, but evangelizing them within a medium-large organization
  • You have a passion for building reliable, performant AI systems and understand how they create value for end users
