Sr. Solution Architect to Govern Enterprise Architecture and Lead Platform Modernization for Automotive Finance Client
Location: Markham, ON (3 days/week on-site, Tuesday to Thursday)

Type: Permanent Full-Time

Our client, a leading Canadian automotive finance organization, is looking for a Solution Architect to join their Enterprise Architecture team in Markham on a permanent basis.

Most development and support is delivered through a large ecosystem of external vendors. Your job is to govern, evaluate, and drive. You are the internal technical authority ensuring vendors are designing and delivering the right solutions, integrating correctly across a complex technology landscape, and meeting the organization's architecture standards.

The team is lean and the mandate is wide. You need to operate independently, cover a broad range of architecture domains, and have the communication skills to hold your own with vendors and business stakeholders at the executive level.

Must-Haves
8-10+ years of solution or enterprise architecture experience, with broad coverage across application, integration, cloud, data, and security domains. Candidates who have specialized in one area on a large architecture team have consistently struggled in this role
Hands-on AWS experience including cloud-native services such as Lambda, EC2, and API Gateway. Must be able to evaluate and govern vendor cloud architecture decisions confidently
Integration architecture experience across complex, multi-vendor environments. Understanding of how APIs, middleware, and systems connect at scale across 40-50 vendor integrations
MuleSoft familiarity. It is the organization's external API gateway and staying in place. Must understand how APIs are managed and how they tie together through MuleSoft
Salesforce integration experience. Salesforce is a major platform in active use and a significant vendor relationship
Familiarity with Java, Node.js,



and Spring on WebSphere or similar on-premise application servers. The organization runs legacy on-premise systems alongside cloud and the architect needs to evaluate vendor work across both
SharePoint and M365 implementation and configuration experience
Robust communication skills and executive presence. This role works directly with business stakeholders, senior leadership, and a large vendor ecosystem. The ability to explain technical decisions in business language and drive consensus is as important as technical depth
Comfortable operating independently with minimal direction in an ambiguous environment

Nice-to-Have
Financial services, auto finance, or regulated industry background
Dealer management system or loan origination platform experience (Route 1, Defi Solutions)
AI and GenAI evaluation experience with responsible AI considerations
Security architecture knowledge in a regulated environment

What You’ll Do
Evaluate and govern solution designs submitted by vendors across Salesforce, MuleSoft, AWS, WebSphere, dealer management systems, loan origination platforms, and a broad vendor ecosystem
Work directly with business stakeholders to understand requirements and translate them into architectural direction and executable designs
Design and oversee integration solutions across a complex multi-vendor technology stack spanning cloud, on-premise, and SaaS
Drive the modernization journey from legacy on-premise systems to cloud and SaaS on AWS
Partner with major vendors including Salesforce, TCS, and others on project execution and ongoing support
Evaluate AI and GenAI opportunities with a risk-first lens including security, privacy, data residency, and regulatory compliance
Produce and maintain architecture documentation including diagrams, interface specifications, and architecture decision records
Contribute to IT strategy, roadmap, and annual technology budget
