Share this job
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 building the future of nation security enablement with agentic AI. Our platform is responsible for tightening the loop from observation to action - providing the warfighter with cutting-edge analysis tools to make better decisions, faster.
We are searching for an experienced product engineer who has previously helped shape agentic AI technology. You will collaborate closely with mission owners in the defense and national security space to build 1) lasting products for which users are enabled by AI and 2) the workflows within these systems to drive mission outcomes.
What you’ll do
- Design, build, and ship a cutting-edge agent-powered mission console using TypeScript, React, Tailwind, Node.js, and Python.
- Partner with customers, mission owners, designers, and other engineers to understand user workflows and create 10x better solutions for their problems leveraging agents.
- Help define and shape the surface for which users are enabled by AI and agents at Vannevar.
- Implement and maintain robust agentic workflows to enable missions at scale.
What we’re looking for
- 5+ years of professional software development experience
- Expertise in TypeScript, Node.js, Postgres, Python, and AWS
- Experience building agents using any framework (LangGraph, Agno, Pydantic AI, etc.)
- Prior experience working in a user-facing product role
- Active Security clearance or ability to obtain one and desire to travel to visit users, collect feedback, and debug issues
- Prior experience developing AI-native products
Competitive Salary
The salary range for this position is $170,000 - $225,000 + equity. Within the range, individual pay is determined by experience, relevant education, and/or training.
What we offer
- Health, dental, and vision insurance

About the role
We’re looking for a senior engineer to lead the development of new Cyber products in support of national security missions. This is a 0→1 builder role - taking a product from concept to operational deployment while working directly with end users and shaping both the product and the problem space.
You’ll own our flagship Cyber product, Cyber Recon - an external attack surface management platform built for cyber operators. This is not a traditional forward-deployed role, but it requires the same level of mission ownership, user empathy, and execution velocity - applied to building a durable product.
What you’ll do
- Own end-to-end development of Cyber Recon and adjacent products (backend systems, data pipelines, and user-facing applications)
- Build intuitive, high-performance interfaces for exploring and acting on complex cyber data
- Work directly with users in mission environments to understand needs, iterate quickly, and deploy into real environments
- Design systems to ingest, normalize, and analyze large-scale external attack surface data
- Translate ambiguous problems into concrete product and engineering decisions
- Drive product and technical direction for Cyber
- Deploy and support software in secure, constrained environments
- Travel 2-3 times per month to customer sites (primarily East Coast)
What we value
- 10+ years building and shipping production software systems
- Strong full-stack skills (backend systems, APIs, data modeling, modern frontend)
- Comfortable moving between frontend, backend, and product decisions on a daily basis
- Experience building user-facing products with strong usability and performance
- Experience operating in ambiguous, fast-moving environments with high ownership
- Experience building cybersecurity products or conducting cyber operations in government environments
- Familiarity with external attack surface management, internet-scale data collection, or adversary infrastructure analysis
- Prior experience working with classified systems or secure deployments
- Currently holds or previously held a CI Polygraph (preferred); ability and willingness to obtain a CI Polygraph required
What we offer
- Health, dental, and vision insurance
- Remote friendly with WeWork access
- Unlimited PTO, shared downtime during the federal holiday calendar, and company-wide off time at the end of each year
- 401(k) match
- Lifestyle & wellbeing stipends
- Salary top-up during military reserve duty
- Fully paid parental leave
- Child and pet care reimbursement during travel
