One Door

Location: Hybrid – Toronto, Canada

At One Door, we are transforming how retailers deliver on their in-store strategies. As the leading provider of SaaS-based visual merchandising solutions, we empower global brands to plan, execute, and analyze in-store experiences through an intelligent, data-driven platform.

As our platform matures and expands across multiple solution areas—data insights, custom applications, and low-code platforms—we are seeking a Solution Architect to drive architectural clarity, consistency, and scalability across our B2B SaaS ecosystem.

Why Join One Door?

• Be a strategic leader influencing the architectural vision of an industry-leading B2B SaaS platform.
• Work across a diverse, modern tech stack while maintaining a broad, platform-first perspective.
• Join a collaborative, hybrid-friendly organization that values clarity, innovation, and execution.
• Competitive salary, benefits, and meaningful opportunities for growth and impact.

Role Overview

As a Solution Architect, you will be responsible for defining, documenting, and communicating the high-level solution architecture across One Door’s platform domains. You will not be expected to deliver detailed technical designs in each area, but rather to set the foundational architecture direction, define interaction and integration standards, and ensure alignment across distributed product and engineering teams.

This role is central to ensuring that all platform capabilities-- whether built in full-stack application architecture, low-code/no-code platforms, or via data & insights systems-- are cohesive, secure, scalable, and aligned to our multi-tenant SaaS strategy. Additionally, you will champion DevOps-aware architecture, ensuring systems are designed for observability, resilience, automation, and cloud-native scalability.

RESPONSIBILITIES

Architecture Strategy & Leadership

• Define and evolve the target solution architecture for key areas of the One Door platform, including insights, app experiences, and low-code environments.
• Develop and maintain architecture blueprints, integration diagrams, and interaction models that guide the work of engineering teams across multiple domains.
• Use formal modeling methods such as UML, data modeling techniques, and structured design approaches to communicate architecture clearly and consistently.

Cross-Solution Integration Standards

• Establish and promote patterns for how platform components interact, including service-to-service communication, shared identity models, and data exchange protocols.
• Define consistent strategies for multi-tenant management, authentication/authorization, and event/data propagation.
• Set architectural guardrails that ensure modularity, interoperability, and platform resilience.

DevOps & Cloud-Native Alignment

• Work closely with DevOps and infrastructure teams to ensure architectural decisions support CI/CD automation, containerization, deployment scalability, and cloud-native operation
• Advocate for architectural designs that consider monitoring, logging, alerting, and automated recovery as first-class concerns.
• Align solution blueprints with cloud architecture principles on Azure or AWS, focusing on cost-efficiency, reliability, and maintainability.
• Contribute to platform readiness for infrastructure as code (IaC) and deployment automation pipelines.

Communication & Governance

• Serve as a central voice in communicating architecture direction to stakeholders across engineering, product, UX, and executive teams.
• Lead architecture reviews, contribute to solution evaluation processes, and arbitrate alignment across teams.
• Maintain and evolve platform-wide architectural documentation, standards repositories, and best practices.

Platform Scalability & Extensibility

• Promote platform-level thinking to ensure extensibility across customers, scalability with growth, and alignment with our productized SaaS vision.
• Address cross-cutting concerns, including performance, observability, maintainability, and data consistency from an architectural perspective.

QUALIFICATIONS

• 8+ years of experience in software architecture, including 3+ years in B2B SaaS platform environments.
• Proven ability to define high-level architecture strategies across diverse technologies (e.g., React, Node.js, Ruby on Rails, Mendix, Fabric/Power BI).
• Skilled in modeling system interactions, component relationships, data flows, and user interaction patterns using UML, data modeling, and structured design techniques.
• Strong understanding of DevOps principles and how architecture supports scalable deployment, automation, and observability in a cloud-native SaaS context.
• Deep knowledge of multi-tenancy, identity federation, API integration, and secure data sharing within platform environments.
• Excellent communicator with the ability to influence and align cross-functional teams without direct authority.
• Strong documentation and presentation skills—able to articulate complex systems to both technical and business stakeholders.

PREFERRED

• Experience in retail technology, visual merchandising, or execution platforms.
• Familiarity with data analytics infrastructure (e.g., Snowflake, Microsoft Fabric, Power BI).
• Experience with Mendix low-code platform governance and architecture is a plus.
• Exposure to event-driven architecture, message queues, or microservices orchestration.
