Spear AI builds machine learning systems for the defense sector, running a heavily engineering-focused org (16 engineers across 22 open roles) with active work on real-time data pipelines, sensor integration, and policy frameworks for AI testing. The tech stack—PyTorch, TensorFlow, Kafka, Redpanda, AWS GovCloud—reflects both classical ML workflows and modern streaming infrastructure; the active shift to Rust and Redpanda while phasing out Protocol Buffers signals a move toward lower-latency, more efficient data handling in high-volume operational contexts.
Spear AI develops artificial intelligence and machine learning solutions for national security and defense applications. Based in Washington, DC, the company works on reinforcement learning, acoustic ML, cloud architecture, and data infrastructure problems specific to the defense industry. Active projects span policy development for AI testing and evaluation, real-time sensor data pipelines (including sonobuoy development), containerization of legacy systems, and operational automation. The team addresses challenges around scaling internal infrastructure, implementing responsible AI frameworks, and managing enterprise-scale data governance in secure environments.
PyTorch, TensorFlow, scikit-learn, Python, R, Apache Spark, Kafka, Redpanda, AWS (including GovCloud), Azure, GCP, Apache Airflow, Dagster, PostgreSQL, and Apache Iceberg. Currently adopting Rust and MQTT; phasing out Protocol Buffers.
Real-time and offline data pipelines, AI policy development for military applications, sensor data infrastructure (sonobuoy development), legacy codebase modernization, and ML/analytics platforms for operational reporting and decision support.
