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.

About the role

Vannevar is seeking an experienced frontend 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 interfaces 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 UIs 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 serve as a technical expert on the team and shape frontend development practices across the organization.

Design, build, and ship cutting edge defense tech applications and features using TypeScript, React, Tailwind, and Node.js
Partner with customers, mission owners, designers, and other engineers to understand user workflows and create the best possible solutions for their problems
Contribute improvements to core libraries and frontend tooling for the broader organization
Mentor and guide other engineers in the art of frontend development
Help define and shape the future of the product

What we look for

11+ years of professional experience in frontend software development
Expertise in TypeScript and React. You know how to write code and components that compose well and can be maintained by others in the future.

Eye for design and attention to detail. You produce elegant, consumer-grade UIs that users can understand without specific training.
Customer obsession and keen product intuition. You think in workflows and end user experience, not just code.
Prior experience as a senior engineer or tech lead and demonstrated ability to mentor and guide more junior engineers.

Nice to have
