Senior Software Subject Matter Expert

Toshiba Global Commerce Solutions is seeking a hands-on Senior Software Subject Matter Expert in Software/Systems Architect and Technical Leader to drive the design, delivery, and evolution of large-scale, distributed software platforms. This role provides deep technical leadership across system software, cloud services, and AI-assisted development, guiding teams through complex architectural challenges while ensuring security, scalability, reliability, and operational excellence. You will lead cross-functional collaboration, define reference architectures and engineering standards, mentor architects and engineers, and influence platform strategy to deliver high-availability, cost-efficient, and future-ready solutions at scale. 

Core Mission: 

Own and evolve resilient, distributed, and AI augmented system software architectures that span hardware, edge, on-prem, and cloud environments. Establish and enforce architectural guardrails for availability, fault tolerance, operability, and long-term architectural health across System Software. 

Responsibilities 

• Guide software development, test, and support teams on complex technical issues and solution design. 

• Own System Software platform and services architecture; define solution design direction and enforce architectural guardrails across teams. 

• Lead crossorganizational architecture and design reviews across HW, System Software, Application SW, SRE, Support, and Professional Services. 

• Define and enforce nonfunctional requirements (security, scalability, reliability) and reference architectures; ensure CI/CD and DevSecOps alignment. 

• Provide handson technical leadership, mentorship, and design governance for architects and developers. 

• Architect, design, and develop largescale distributed software services and solutions in collaboration with teammates. 

• Translate discovery outcomes into actionable backlog items, ensuring design intent, architectural standards, and NFRs are preserved. 

• Shape platform and portfolio strategy by identifying reusable capabilities, APIfirst opportunities, and gaps requiring investment. 

• Operationalize AI/agentic workflows for design acceleration, prototyping, code and test generation, and automated validation. 

• Define governance for AIassisted development, including traceability, safety, and ethical use. 

• Communicate effectively across global geographies to maintain architectural coherence. 

• Produce reference architectures, design standards, and internal white papers. 

• Collaborate with development and product teams to design highquality software solutions. 

• Design solutions emphasizing high availability, scalability, robustness, and usability. 

• Build prototypes and POCs to validate architectural decisions and derisk key choices. 

• Drive bestinclass engineering practices through code/design reviews and datadriven decisionmaking. 

• Ensure services and components are modular, secure, reliable, reusable, diagnosable, and actively monitored. 

• Stay current on modern technologies, cloud deployments, and microservice patterns; conduct POCs to evaluate technology fit. 

• Drive diagnosability and operability through structured logging, metrics, tracing, and endtoend observability practices. 

• Influence portfolio strategy to reduce architectural debt and long-term operational risk. 

Core Qualifications 

• Bachelor's or Master's degree in Computer Science, Engineering, or related field. 

• 10+ years of experience in software development and architecture, with a focus on cloud-based solutions and microservices. 

• Experience with networking implementation and problem solving. 

• Expert in and leverage the seven layers of OSI to work through complex issues
