Senior Backend Engineer, Collection
About this role
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
We are looking for an experienced Backend Engineer to build and refine our data collection and processing applications. You’ll be in charge of designing and building scalable, robust systems that collect mission-critical data and then building out pipelines for those data. You will be a technical leader, improving existing systems and personnel, and supplying our product suite with rich, comprehensive data.
You are innovative: willing to take risks, think critically about novel solutions, and advocate for your ideas while seeking feedback and collaboration. You will be making trade-offs as you work to ensure that our systems are prepared to scale — being able to effectively communicate these trade-offs with your teammates is a must.
You will creatively engineer solutions to access hard-target data, structuring messy data streams into valuable information that partner teams can use to build custom DoD workflows with our customers.
