Overview

We are seeking a highly skilled C/C++ Software Engineer to support mission‑critical Command, Control, Communications, Computers, and Intelligence (C4I) systems for U.S. Customs and Border Protection’s Air and Marine Operations Center (AMOC). This role supports the Air and Marine Operations Surveillance System (AMOSS) and related ISR systems that provide real‑time air and maritime domain awareness across national and international operating areas.

The engineer will work on advanced radar tracking, sensor fusion, data correlation, and real‑time operational displays that directly support homeland security and law enforcement operations.

Location: US-VA-McLean

Responsibilities

• Design, develop, enhance, maintain, and debug C and C++ software supporting AMOSS and associated C4I systems.
• Develop and maintain advanced radar tracking, correlator, and sensor fusion algorithms.
• Integrate new air, maritime, and ground‑based sensors and data feeds into AMOSS.
• Support ingestion and correlation of radar plots, track data, flight plan data, GPS tracking, ADS‑B, and tactical data links.
• Modify and enhance AMOSS user interfaces, including real‑time displays and data visualization components.
• Develop and maintain interfaces for both dedicated AMOSS clients and Web‑based AMOSS capabilities.
• Support second‑tier software maintenance, advanced troubleshooting, and system performance optimization.
• Participate in system upgrades, refreshes, and deployments at AMOC, CAMOC, COOP, and international partner sites.
• Ensure software changes comply with DHS, CBP, and AMOC configuration management and security requirements.
• Support installation, integration, testing, and validation of software changes in operational and test environments.
• Develop and maintain tracking and correlation algorithms, including adaptive Kalman filtering for target smoothing and prediction and optimal assignment algorithms for plot‑to‑track correlation.
• Support enhancements related to data mining, analytics, and predictive threat modeling.
• Collaborate with data scientists and system engineers supporting AI/ML‑enabled threat detection systems (e.g., Kestrel).
• Produce and maintain technical documentation, including Software Version Description Documents (SVDD), Installation Plans (IP), Systems Acceptance Test Plans (SATP), and source code documentation for long‑term sustainment.
• Participate in technical interchange meetings with government stakeholders.
• Support Program Management Reviews (PMRs) and operational briefings as required.
