Career Opportunity

We have an exciting opportunity to lead and shape enterprise solution architecture within a dynamic and forward-thinking IT environment. If you're passionate about aligning technology with business strategy and leveraging innovation, this Senior Solution Architect role is for you!

What You Will Do

Reporting to the Director, Strategy and Architecture, as a Senior Solution Architect, you will lead the development and implementation of the Enterprise Solution Architecture (ESA), ensuring it aligns with organizational goals and is effectively leveraged across projects. This unique opportunity will directly impact how millions move across the region every day.

In this hands-on role, you will be responsible for designing and developing cohesive, scalable solution architectures. You will collaborate with enterprise architects specializing in applications, data, information, and technology to create integrated and future-ready solutions.

Working closely with project teams, business stakeholders, and IT staff, you will define and oversee key architecture domains and solution portfolios—such as applications, service-oriented architecture (SOA) services, and shared infrastructure. Additionally, you will develop strategic roadmaps to guide their evolution from current to future states.

In this role, you will provide architectural guidance across business, information, and technology domains, analyzing business trends and strategic changes to inform solution decisions. You will also establish foundational principles, models, and solution patterns that support enterprise-wide design consistency and innovation.

You will consult with development teams to ensure systems and infrastructure are aligned with the Enterprise Solution Architecture (ESA). You will work closely with the Project Management Office (PMO) to maintain alignment between architectural roadmaps and project plans. Additionally, you will coordinate with both business and technical teams to support implementation activities and adapt the solution architecture as needed to meet evolving project requirements.

Demonstrate behaviors that support diversity, inclusion, and a respectful work and service environment that is free from discrimination and harassment. Help to remove barriers and accommodate employees and customers (within their area of responsibility) in accordance with TTC’s commitments and obligations under the Ontario Human Rights Code (OHRC) and Related Orders, the Accessibility for Ontarians with Disabilities Act (AODA), and TTC’s policies.

Participate in the TTC Customer Service Ambassador Program.

• The role demands the ability to understand both long-term strategic goals and short-term operational needs, translate business requirements into solution architecture, estimate the financial impact of ESA and solution alternatives, define multiple solution options, and quickly grasp the capabilities of emerging technologies.
