Description & Requirements
Elder Research Inc., a wholly owned subsidiary of MANTECH international Corporation seeks a motivated, career and customer-oriented Senior Full-Stack Engineer to join our team in Arlington, VA who will help lead development of the analytics platform. This is a high-ownership role: you'll drive front-end architecture decisions, contribute meaningfully to Python backend services, mentor engineers on the team, and ship complex features end-to-end.
The balance between front-end and back-end work in this role evolves with the product—some sprints emphasize UI development, while others focus on Python-based pipelines and document-processing services. We’re seeking a true full-stack engineer who is equally comfortable operating across both layers and can adapt as priorities shift, rather than someone with a strong bias toward one side of the stack.
As a Sr. Full-Stack Engineer, you will lead front-end architecture for a growing internal platform, driving component design, state management, routing, and performance optimization, while also contributing to Python backends that power document processing, OCR, summarization, and inference pipelines. You will build end-to-end large-scale PDF upload workflows with chunking, resumability, progress feedback, and robust error handling, supported by scalable Python services, and develop interactive prompt-guidance and conversation continuity features, including context upload and deep integration with OCR and inference systems.
