Title:

Senior Systems Engineer / Model-Based Systems Engineering Lead

At KBR, we deliver science, technology and engineering solutions to governments and companies around the world. KBR employs approximately 37,000 people worldwide with customers in more than 85 countries and operations in over 28 countries. KBR is proud to work with its customers across the globe to provide technology, value‑added services, and long‑term operations and maintenance services to ensure consistent delivery with predictable results.

Trinzic is the future independent company to be created through the planned spin‑off of KBR's Mission Technology Solutions business, expected in January 2027. Our people work at the frontier of what is possible, delivering solutions in challenging environments and advancing some of the world's highest‑priority national security and space missions.

Backed by decades of mission success, deep expertise, and trusted partnerships, Trinzic will launch as a global organization with more than 18,000 employees supporting customers around the world. Join us at a defining moment and help shape the future of a company built to tackle complex challenges and make a meaningful impact.

Candidates who join KBR's Mission Technology Solutions business before the spin‑off will transition to Trinzic when the separation is complete and will not need to reapply for employment.

The program team this engineer will join supports more than 20 projects across systems engineering, integration, and reliability engineering analysis for Naval Aviation. The selected candidate will become part of a collaborative KBR team where coordination across projects, disciplines, and technical leaders is encouraged by program leadership.

Why Join Us?

Innovative Projects: Support high-impact Naval Aviation work that applies modern engineering methods, emerging technologies, and mission-focused solutions to complex defense challenges.

Collaborative Environment: Work with experienced engineers, program leaders, and technical teammates in a collaborative setting that values coordination across projects and disciplines.

Impactful Work: Contribute directly to the engineering, integration, and sustainment of defense systems that support mission readiness and national security.

Career Growth: This project has rapid growth potential, with strong opportunities for increased responsibility, technical leadership, and potential upward mobility within the next 12 months as team and program needs evolve.

Roles & Responsibilities:

• Lead systems engineering support for NAVAIR aircraft survivability and electronic warfare programs, with emphasis on the AN/ALE-47 Common Carriage system and iASE Programmer.
• Develop, review, decompose, allocate, trace, and verify system, subsystem, hardware, software, interface, cybersecurity, and verification requirements.
• Develop and maintain SysML system architecture models, requirements relationships, interface models, and black-box and white-box system representations using MBSE tools.
• Analyze electrical, data, control, and communication interfaces, including Ethernet, MIL-STD-1553, RS-422, discrete signals, aircraft power, secure connectivity, and mission-data loading.
• Coordinate cybersecurity, information assurance, configuration management, integration, qualification, and verification activities with platform teams, technical authorities, developers, testers, laboratories, and government stakeholders.
• Review contractor designs, specifications, interface documentation, engineering-change proposals, drawings, bills of material, test documentation, and configuration-controlled baselines.
• Support technical reviews, test planning, environmental and electromagnetic-interference qualification, laboratory and aircraft integration, performance verification, and requirements closure.
• Prepare technical briefings, engineering recommendations, trade studies, risk assessments, impact analyses, action-item responses, and decision-support products for program leadership.
• Provide day-to-day technical leadership, mentoring, staffing input, and coordination with government organizations, aircraft platform teams, laboratories, logistics organizations, and industry partners.
