Senior Application Architect
About the role
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 work closely with our Custom Software Solutions development team, global database administrators and business stakeholders/SMEs to translate business requirements into technical solutions, and guide projects through to successful implementation.
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).
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.
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.
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.
Stakeholder Collaboration: Collaborate with stakeholders across the organization – including business Subject Matter Experts (SMEs), business analysts, project managers, and IT leadership – to understand requirements and translate business requirements into technical architecture designs (communicating complex architectural concepts in clear terms to non-technical stakeholders, ensuring buy-in and understanding).
Project Involvement: Take part in planning and executing IT projects as the architecture owner. During project planning, estimate the effort and resources needed for architectural tasks and any new infrastructure. Throughout development, the Senior Application Architect monitors progress to ensure alignment with the architectural design and intervenes if refactoring is needed. They might lead proof-of-concept initiatives to validate new technologies, design patterns or approaches before wider implementation.
Continuous Improvement: Stay updated with emerging technologies, tools, and best practices in the industry. This includes keeping current with cloud innovations, DevSecOps tools, and new Oracle EBS features or Oracle Fusion Cloud offerings. The Senior Application Architect evaluates these for potential benefit to the organization and drives adoption of new technologies (for example, exploring the use of Oracle Integration Cloud or new Azure services). They may also establish best practice guidelines and technical standards internally, fostering continuous improvement in how Stantec designs and delivers software.
Qualifications & Skills
Education: Degree or diploma in Computer Science, Software Engineering, Information Technology or a related field (or equivalent professional experience).
Experience: Extensive experience in software development and architecture. Typically, 8+ years in software engineering/architecture covering the full software development lifecycle, with at least a couple of years in a senior application design/architecture capacity. Experience should include designing complex systems and making complex technical decisions.
Oracle EBS Expertise: Proven experience working with Oracle E-Business Suite (EBS) in an architectural or senior development role. Candidates should have participated in full lifecycle implementations or major upgrades of Oracle EBS and have a deep understanding of EBS modules (e.g., Financials, Project Billing and Costing, HCM etc.). Knowledge of the Oracle EBS technical stack is required – e.g. Oracle Database and PL/SQL, Oracle Forms/Reports, Workflow, and interface tools. Ability to design or review customizations, data migrations, and integrations involving EBS is essential.
Cloud Architecture & Services: Strong expertise in cloud computing platforms and services. Hands-on experience in designing and deploying applications on Oracle Cloud and/or Microsoft Azure is required. This includes familiarity with cloud services such as compute, storage, databases, networking, and cloud-native design patterns. The architect should be comfortable with various multi-tier, microservices and event driven architecture patterns and understand how to leverage cloud offerings (like serverless functions, messaging services, etc.) in solution designs.
DevOps & CI/CD & Agile Practices: Embraces a DevSecOps culture for quicker and more reliable deployments – including continuous integration, continuous delivery/deployment (CI/CD), and automated testing. Also, following Agile methodologies (e.g., Scrum or Kanban) to iteratively deliver architecture components and adapt to changes. In-depth knowledge of DevSecOps principles and tools. Ability to build and/or maintain CI/CD pipelines using tools such as Terraform, Azure DevOps, or GitLab CI/CD. Experience with configuration management and automation (e.g., Ansible, Puppet, or Chef) and with containerization technologies (Docker, Kubernetes) is expected.
Systems Integration: Strong integration skills – ability to design and implement APIs and middleware for connecting heterogeneous systems. Experience with web services (RESTful APIs, SOAP) and enterprise application integration patterns is required. Given the Oracle EBS focus, knowledge of integration tools or middleware (such as Oracle Integration Cloud, Oracle SOA Suite, or other ESB tools) is advantageous for orchestrating data flows between EBS and other applications.
Technical Proficiencies: Proficiency in programming and scripting languages relevant to the enterprise stack. This may include Python/Django, Java or C# for application development. Solid skills in SQL and working with relational databases (particularly Oracle Database and PL/SQL) are required. Comfortable working in a Linux environment. Familiarity with version control systems and build tools is also expected as part of the development toolkit. Experience with RESTful web services and frameworks to build APIs is important.
Architecture & Modelling Tools: Use of modelling tools to create architecture diagrams and documentation – e.g. Microsoft Visio, Draw.io, Lucidchart or UML design tools. Architecture & Design Knowledge: Strong grasp of software architecture principles and design patterns. Ability to create models/diagrams (using UML or similar) to communicate system structure. Knowledge of established architecture frameworks (such as TOGAF or Zachman) and design methodologies is optional but beneficial, as it provides a structured approach to designing enterprise systems.
Methodologies: Experience with Agile/Scrum development processes and understanding of the DevSecOps culture of collaboration between development and operations. The candidate should be comfortable working in an iterative, fast-paced project environment and ideally have been part of agile teams. They should also be versed in continuous improvement practices and possibly have experience with other methodologies like ITIL for service management or PRINCE2/PMP for project management (even if the role is not project manager, this helps in alignment with project processes).
Testing & Quality: Knowledge of automated testing frameworks (for unit testing, functional testing, systems integration testing, non-functional testing, security testing etc.) and performance testing tools would be helpful.
