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.

Key Responsibilities

• Design and Architecture: 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., recommending which systems to migrate to cloud or how to refactor legacy EBS custom applications).
• Cloud & Infrastructure: Provide expertise in cloud services (such as Oracle and/or Azure) and architect cloud-based applications or migrations. Ensure all cloud solutions follow security and compliance requirements. Design microservices-based systems on Azure that integrate with on-premises Oracle databases, adhering to cloud provider best practices and internal guidelines.
• Oracle EBS Integration: Serve as the subject matter expert on Oracle E-Business Suite (EBS) within the architecture. Ensure that new and existing applications integrate seamlessly with Oracle EBS where necessary (e.g., Financial or Project Accounting systems interfacing with Oracle EBS). Provide guidance on Oracle EBS enhancements and customizations, ensuring they are done in line with best practices to maintain system stability and upgradability. Design APIs or middleware for data exchange between Oracle EBS and existing applications, cloud applications, or advising on Oracle EBS configuration to support new business requirements.
• Technical Leadership: Provide technical leadership to software development teams throughout the software development lifecycle. Lead architecture review sessions and code reviews, mentor developers, and act as a bridge to the custom software development team to communicate architectural decisions and rationale. Ensure adherence to design principles and patterns (e.g., modular design, microservices, event-driven architecture).
• Performance, Security & Compliance: Incorporate security requirements and performance considerations into all architecture designs. Ensure applications adhere to security best practices and relevant compliance standards. Work with IT Security to perform risk assessments and include data protection controls and robust error handling. Design for high performance and availability with load balancing, caching, and failover mechanisms. Ensure reliability, maintainability, and disaster recovery preparedness.
• Stakeholder Collaboration: Collaborate with stakeholders across the organization to understand requirements and translate them into technical designs. Participate in requirement-gathering workshops and liaise with vendors or external partners when third-party systems or cloud services are involved.
• Project Involvement: Participate in IT project planning as the architecture owner. Estimate effort and resources for architectural tasks, monitor progress, and intervene if refactoring is needed. May lead proof-of-concept initiatives and ensure proper architectural documentation for future reference and onboarding.
• Continuous Improvement: Stay updated with emerging technologies, cloud innovations, DevSecOps tools, and Oracle EBS features. Drive adoption of new technologies and establish internal best practices and technical standards.
