Software Systems Architect - Clearance Required

Overview

LMI is seeking an experienced Software Systems Architect to support the U.S. Army Training Information System (ATIS) program and the ALCMC delivery team. ATIS is a major Army initiative to modernize and consolidate Army training systems into a secure, cloud-native, enterprise-level capability. As part of an Agile Release Train (ART) operating under the Scaled Agile Framework (SAFe), this role will lead team-level technical architecture and solution design, establish architectural runway, guide interface and integration decisions, and enable the team to deliver secure, scalable, and maintainable capabilities within broader solution architecture guardrails.

This is a highly technical, collaborative, and hands-on individual contributor role
. The Software Systems Architect will work directly with developers, Product Management, Dev Sec Ops , testing, cybersecurity, and Solution Architecture to translate mission and product needs into implementable designs, reduce technical ambiguity and rework, manage architectural and technical-debt risks, and ensure architecture actively enables delivery rather than becoming an approval gate.

The ideal candidate combines strong architectural judgment with hands-on software engineering experience and is comfortable working directly with engineering teams through design, implementation, integration, troubleshooting, and technical problem solving.
