Our business teams include finance, procurement, human resources, information technology, marketing, corporate development, HSSE, real estate, legal, and practice services. Webring diverse backgrounds, skills, and expertise and create a caring culture where everyone can thrive. Through teamwork and collaboration, we’re building a stronger, more resilient Stantece every day.

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.

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 . This includes creating strategies for integrating cloud services with existing systems (e.g. ensuring new cloud applications interface smoothly with Oracle EBS). The Senior Application Architect analyzes current application portfolios and identifies opportunities to improve or modernize them (for example, 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. For example, the Senior Application Architect might design a microservices-based system on Azure that integrates with on-premises Oracle databases, adhering to both 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.

This could involve designing APIs or middleware for data exchange between Oracle EBS and existing on-premises 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, ensuring solutions align with the defined architecture and coding standards. Mentor and guide developers in implementing the architecture correctly and assist in troubleshooting complex issues. The Senior Application Architect will act as a bridge to our custom software development team, communicating architectural decisions and rationale.

They will ensure the development team understands and follows design principles (e.g. modular design, microservices, event driven architecture etc.) and make use of appropriate design patterns.

Performance, Security & Compliance
Incorporate security requirements and performance considerations into all application architecture designs from the outset. The architect makes sure that applications adhere to security best practices and relevant compliance standards as required. They will work with Stantec’s IT Security team to perform risk assessments on new architectures and include controls for data protection (encryption, access control) and robust error handling. They will also design for high performance and availability – for example, recommending load…
