Backend Software Engineer - Data Platform

The Data Platform team is responsible for the pipelines, search, and identity systems that are foundational to Vannevar’s flagship platform and agentic workflows. The systems we build and operate define and enforce standards for data processing, storage, access, and retrieval across a growing suite of 10+ products.

You will be part of a team that builds and manages this business-critical infrastructure. In this role, you’ll have the opportunity to serve as a technical leader—shaping patterns for enterprise-grade performance, scalability, reliability, quality, and security across the broader organization.

You’ll partner closely with product engineering teams to standardize and centralize shared infrastructure, reducing duplication and improving developer velocity. You’ll also collaborate with our Information Security team to ensure our systems meet the stringent security and compliance requirements of DoD environments. Finally, you’ll have an opportunity to craft the long-term strategy for the platform, guiding architectural decisions and investments that enable the company to scale safely and sustainably.
