Senior AI/ML Engineer
About The Position
The defense market is surging, but the data that drives it hasn't kept up. Companies, government, and investors are forced to perform heavily manual processes and piece together hundreds of disparate sources to make critical decisions for national security. Obviant is building the data source of truth to power the entire defense acquisition system. We fuse information from thousands of sources (structured and unstructured) to provide a cohesive picture of budget, programs, the organizations running them, and much more. We're growing quickly on the back of strong customer satisfaction at top-tier accounts, backed by leading venture funds, and advised by veterans from national security and the technology industry. At Obviant, you'll build the ML systems that turn sprawling, unstructured defense and government data into a knowledge graph our customers can actually reason over. As an AI/ML Engineer, you'll own problems end to end — designing transformer-based extraction and entity-resolution pipelines, adapting language models to a specialized domain, and helping shape the ontology that underpins the product. You'll work on a small team where your decisions show up in the product within weeks, alongside engineers and domain experts who know the mission cold. We care less about buzzword coverage than about people who can take an ambiguous, messy problem and make it rigorous and shippable.
