Product Engineer

Role Description

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.
