SciTec has an immediate opportunity for a talented Machine Learning & AI Engineer to support our programs delivering Next-Generation Missile Warning software. This is a unique opportunity to join a small business delivering core capabilities for national defense. You will work within a fast‑paced team developing end‑to‑end machine learning and analytics pipelines for Overhead Persistent InfraRed (OPIR) sensor data supporting Missile Warning, Missile Defense, Battlespace Awareness, and Technical Intelligence.

We are seeking a Staff/Senior Staff Machine Learning & AI Engineer to design, train, and optimize high‑performance ML models and algorithms that enhance remote sensor data exploitation and analysis. This role focuses on hands‑on algorithm development, model optimization, and integration into production software systems running on Linux.

The ideal candidate is a strong individual contributor with deep experience in machine learning, high‑throughput data processing, and applied algorithmic development. Success in this role requires technical curiosity, rigorous engineering practices, and the ability to collaborate effectively within a highly technical, Agile team.

Responsibilities

Develop and implement machine learning, deep learning, and AI algorithms for remote sensor data exploitation

Design, train, and optimize models supporting image analysis, detection, tracking, and multi‑modal sensor fusion

Deploy high‑performance inference pipelines for large‑volume, real‑time or near‑real‑time data processing

Collaborate closely with C++ and system-level engineers to integrate ML/AI solutions into existing software frameworks

Apply strong software engineering practices to ensure model reproducibility, performance, and maintainability

Work as part of an Agile team and contribute to shared tools, workflows, and documentation

Other duties as assigned

Requirements

A Bachelor’s degree in the physical sciences, mathematics, engineering, computer science, or a related field (Additional years of education may be substituted for years of professional experience)

At least five years of professional experience in machine learning, AI engineering, or applied algorithm development
