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
At least three years of experience working in Linux environments
Proficiency with Python and common ML frameworks (e.g., PyTorch, TensorFlow, scikit-learn)
Strong understanding of data structures, numerical methods, and algorithm design
Experience optimizing models and pipelines for high‑data‑throughput processing
Feature engineering and statistical tests, such as Mutual Information and Shapley Analysis
Detail oriented with strong problem‑solving skills
Good verbal and written communication skills
Ability to work full‑time in-person at the Boulder, CO office location
Ability to obtain and maintain a DoD security clearance

Preferred Qualifications

Experience with GPU programming and acceleration (CUDA, cuDNN, TensorRT, ROCm, etc.)
Direct experience applying ML/AI techniques to OPIR, E/O, SAR, Spectral, RF, or other remotely sensed data
Strong understanding of modern software engineering principles, including object‑oriented design and SOLID principles
Experience with production deployment of ML models, MLOps pipelines, or real‑time inference systems
Familiarity with C++17/20/23, especially for model integration or high‑performance compute components
Advanced degree (MS or PhD) in the physical sciences, mathematics, engineering, computer science, or a related discipline
Professional fluency in one or more additional languages: Python, Rust, or C++
Prior experience in Agile software development environments
A current active DoD SECRET clearance or higher
