Job description

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 you’ll do

• Product engineering: Lead the Systems Agents team in designing, building, and shipping a cutting-edge coding harness and broader product(s) for systems modernization using TypeScript, React, Tailwind, Node.js, Python, Postgres, and AWS.
• Product integration: Build integrations between source control systems, CI/CD platforms, requirements management tools, security scanners, developer environments, and other commercial software products to create end-to-end modernization workflows.
• Agent leadership: Guide the implementation and scaling of robust agentic workflows that enable system refactoring and software re-architecture at scale, using modern agent frameworks and patterns.
• Customer and mission partnership: Partner with customers, mission owners, designers, and product teams to understand user workflows and drive concrete outcomes aligned with real-world workflows.
• AI-native product strategy: Help define and shape how software engineers, system architects, and program managers across program offices supporting DoW are enabled by AI and agents at Vannevar, balancing ambitious product vision with reliable execution.
