Senior Application Architect Stantec is looking for a Senior Application Architect that will be responsible for designing and overseeing the architecture of various software systems. The Senior Application Architect role ensures that applications (both cloud-based and on-premises) are scalable, secure, and integrated with existing systems, including our Oracle EBS ERP platform. They will work closely with our Custom Software Solutions development team, global database administrators and business stakeholders/SMEs (Subject Matter Experts) to translate business requirements into technical solutions, and guide projects through to successful implementation. The initial focus of the role will be to work with business stakeholders/SMEs to optimize workflows and business processes between our Project Managers and Project Accountants (aka PM2PA). This will involve enhancing and integrating numerous existing applications and data stores, including our on-premises Oracle E-Business Suite, and in the future, Oracle Fusion Cloud apps. Responsibilities Design and document the overall application architecture for projects, spanning on-premises systems and cloud platforms. Ensure architectures are scalable, reliable, and meet business requirements. Create strategies for integrating cloud services with existing systems (e.g., ensuring new cloud applications interface smoothly with Oracle EBS). Analyze current application portfolios and identify opportunities to improve or modernize them (e.g., migration to cloud or refactoring legacy EBS custom applications). Provide cloud and infrastructure expertise, architect cloud-based applications or migrations, and ensure security and compliance of cloud solutions. Design systems (e.g., microservices on Azure) that integrate with on-premises Oracle databases while following cloud provider best practices and internal guidelines. Serve as the Oracle E-Business Suite (EBS) subject matter expert within the architecture. Ensure new and existing applications integrate with Oracle EBS where necessary (e.g., Financial or Project Accounting interfacing with Oracle EBS). Guide EBS enhancements and customizations in line with best practices to maintain stability and upgradability. Design APIs or middleware for data exchange between Oracle EBS and other applications as needed. Provide technical leadership to development teams throughout the software development lifecycle. Lead architecture reviews and code reviews, mentor developers, and translate architectural decisions to non-technical stakeholders. Ensure adherence to design principles and design patterns. Incorporate security requirements and performance considerations into all architecture designs. Work with IT Security to perform risk assessments, implement data protection controls, and design for high performance and availability (e.g., load balancing, caching, failover). Ensure solutions are reliable, maintainable, and have disaster recovery planning. Collaborate with stakeholders across the organization (SMEs, business analysts, project managers, IT leadership) to understand requirements and translate them into technical designs. Participate in requirement-gathering workshops and liaise with vendors/external partners as needed. Participate in IT project planning as the architecture owner. Estimate effort and resources for architectural tasks and infrastructure. Monitor development progress to ensure alignment with the architecture and intervene when refactoring is needed. May lead proof-of-concept initiatives and ensure proper architectural documentation for future reference and onboarding.
