Data Engineering Software Engineer, Senior

Booz Allen Hamilton is seeking a Senior Data Engineering Software Engineer to build backend services and data infrastructure for integrated products. The role involves designing contract-driven APIs and data pipelines that handle real-time data, ensuring reliable and scalable services.

Responsibilities:

• Own the backend services and data infrastructure for two integrated products
• Build APIs that other engineers build against with confidence
• Design data pipelines that handle messy real-world inputs without silent failures
• Make architectural choices that hold up as the product scales beyond its first use case
• Ensure that data flows cleanly from ingestion to reasoning to presentation without friction or failure
• Build in a rapid development environment with AI-native tooling, delivering reliable and scalable services

Requirements:

• 5+ years of experience designing and building backend services and APIs in Python
• Experience in FastAPI, Flask, or asynchronous web frameworks
• Experience designing contract-driven APIs where multiple consuming services depend on stable and versioned interfaces
• Experience building data ingestion and processing pipelines that handle streaming or near-real-time data, including validation, transformation, and state management
• Experience with relational databases, event streaming platforms, and caching layers for systems that manage both transactional and time-series data
• Ability to obtain a Secret clearance
• Bachelor's degree in computer science or software engineering
• Experience building repository or catalog systems that manage versioned assets with metadata, provenance, and access control
• Experience implementing authentication, audit logging, and schema validation at service boundaries for systems that handle sensitive data
• Experience building products for defense, intelligence, or national security customers
• TS/SCI clearance with a polygraph
• Master's degree in computer science or software engineering
