Application Architecture Engineer

A career as an Application Architecture Engineer within National Bank’s Digital Studio means designing and building the architectures that power the digital experience of millions of personal banking clients. You combine technical expertise, influence‑based leadership, operational rigor and boldness to help deliver robust, secure and scalable solutions—while challenging the status quo and accelerating innovation.

Your role

• Design application architectures (back‑end, web and mobile front‑end) tailored to business and product needs, as well as non‑functional requirements such as security, performance, scalability and resilience.
• Ensure system integration and interoperability within a microservices ecosystem, including REST and GraphQL APIs and event‑driven architectures.
• Document and model application architectures (C4 diagrams, ADRs) to facilitate maintainability and reuse.
• Ensure compliance with the organization’s architecture standards, norms and positioning.

Delivery and quality

• Actively contribute to code by designing, developing and delivering solutions while adhering to TDD, CI/CD practices and quality standards related to code coverage, security and maintainability.
• Support and guide delivery teams throughout project execution through design reviews, peer reviews and participation in code reviews.
• Take part in architecture rituals such as communities of practice, complexity estimations and design reviews, and contribute to the evolution of standards and processes.
• Ensure that production incidents are analyzed, that sustainable solutions are implemented, and that lessons learned are captured and shared.

Innovation and simplification

• Challenge the status quo by proposing innovative architectures, optimizing deployment processes (automation, serverless, FinOps) and exploring emerging technologies such as generative artificial intelligence and productivity tools.
• Develop solutions and tools to accelerate and increase the reliability of team deliveries.
• Integrate observability and monitoring mechanisms to anticipate issues and optimize system maintainability.

Visibility and mentoring

• Present and advocate architectural decisions to broad audiences, both technical and business.
• Actively share knowledge within communities of practice, through mentoring sessions and by supporting more junior team members.
• Exert a positive influence within the technical community to help evolve collective intelligence.

Your team

Within the Digital Studio (Personal Banking Digital Delivery), you join a specialized team of architecture designers, software development directors and site reliability engineers, all reporting directly to the Senior Director, Software Development, within a collaborative structure. This team is part of the Digital Studio, which brings together more than a hundred colleagues and is recognized for its expertise in customer experience development, consistent delivery quality and dynamic collaborative culture.

Requirements

• Hold a bachelor’s degree in information technology or a related field, combined with a minimum of seven years of experience in web and mobile software development.
• Demonstrate strong expertise in modern application architecture, including microservices, REST and GraphQL APIs, and event‑driven architectures.
• Possess solid mastery of at least one technical focus area, either back‑end or front‑end development, with a good understanding of the other.
• Have proven experience in cloud environments, particularly AWS, including deployment, containerization and continuous integration practices.
• Demonstrate strong communication and influencing skills, with the ability to explain technical concepts, align diverse stakeholders and guide teams toward sustainable solutions.
