## About the role

Vannevar builds an agentic system that helps operators make sense of high-volume mission data and act with greater speed and confidence in sensitive government environments. The system analyzes millions of mission-relevant records to surface high-fidelity recommendations, near-real-time analysis, and decision-ready outputs while integrating into the systems and workflows customers already use.

## What they're looking for

- Own mission problems end-to-end: understand the user and workflow, determine what good looks like, design the technical approach, build it, deploy it, and own the outcome
- Architect, build, and own the direction for a product deployed directly to customer environments in support of mission-critical use cases
- Work directly with users and senior technical stakeholders to understand mission needs, constraints, existing systems, and where software can have the greatest impact
- Own end-to-end technical delivery for new mission workstreams, from requirements gathering and system design through implementation, deployment, and sustainment
- Write substantial production code across the stack and improve the product's capabilities, performance, and scalability
- Collaborate with cross-functional partners — including engineers, product designers, and mission domain experts — to plan and deliver complex software features
