Senior Manager, Platform Engineering (Toronto)

Platform Engineering Senior Manager

The opportunity Heart & Stroke offers hybrid work options. For this role, candidates can work from anywhere in Canada. The Platform Engineering Senior Manager leads a team of business analysts and platform engineering resources, accountable for the technology selection, planning, delivery, evolution, and operational excellence of Heart & Stroke’s enterprise digital platforms. The role plays a significant leadership role in enterprise platform assessment and selection, including technical due diligence, architecture fit, integration approach, scalability, security, and transition considerations across current and emerging platform domains.

The role has primary near‑term accountability for leading the technology planning, migration, and operational transition to a modern CMS/Digital Experience Platform (DXP), in support of the organization’s enterprise Constituent and Mission Impact strategy. In parallel, this role contributes to enterprise CRM roadmap development, driving delivery, and prepares the platform engineering function to support additional enterprise platforms, including HRIS and grant‑management systems, as the portfolio expands, applying platform engineering leadership, architecture, and delivery patterns to rapidly assess, structure, and scale these domains. Working in close collaboration with the Director, Application & Platform Engineering, this role provides hands‑on technical leadership across platform solutioning, architecture, integration, and delivery. The Senior Manager leads the end‑to‑end execution lifecycle, from discovery and design through development, testing, deployment, and transition to operations, ensuring platforms are scalable, secure, maintainable, and aligned with enterprise architecture and business objectives.

The role operates at the intersection of business and technology. Business teams own service outcomes and requirements, while this role is accountable for the underlying technology platform strategy, including platform selection (from a technical perspective), architecture, integration scalability, and ongoing technical delivery and operations. The role combines hands‑on engineering leadership with people leadership, guiding teams through platform migrations and implementations while working cross‑functionally with Application Engineering, Data, Security, Infrastructure & Operations and business stakeholders across the enterprise, including product, fundraising, mission, and marketing. As the platform portfolio grows, this role is expected to help scale the platform engineering function, in close collaboration with the Director, by building and structuring leadership across platform domains to ensure explicit ownership, effective delegation, and sustained delivery across enterprise platforms.

Responsibilities

Stakeholder Engagement & Collaboration

• Partner with enterprise partners: business, product, fundraising, mission, marketing, and project stakeholders to clarify platform priorities, business outcomes, dependencies, and delivery sequencing across enterprise platforms.
• Translate business needs, and service objectives into enterprise platform technology strategy, selection, delivery approaches, clearly articulating risks, trade‑offs, constraints, and implementation considerations.
• Provide clear communication of platform delivery status, risks, dependencies, and decision points to technology leadership and business stakeholders.
• Working with the Director of Applications and Platforms Engineering, build alignment across business and end‑to‑end technology teams to support cohesive delivery across platforms, applications, data, integrations, and operations.
• Communicate technical concepts clearly to non‑technical stakeholders and bridge non‑technical and technical audiences to ensure seamless delivery.

Platform Strategy, Planning & Prioritization

• Lead technology planning, technical roadmap development and platform assessment across enterprise platforms, with primary focus on CMS/DXP modernization and secondary focus on CRM evolution and adjacent platform domains.
• Lead or co‑lead technical due diligence, architecture evaluation, integration planning and technical product selection activities for enterprise platform initiatives, in close collaboration with the Director and business stakeholders.
• Prioritize and sequence platform work across multiple concurrent initiatives, balancing business value, technical risk, architectural integrity, delivery capacity and operational sustainability.
• Apply platform engineering leadership, architecture, and delivery patterns to assess, structure and scale emerging platform domains, including HRIS and grant management.

Project Intake, Solution Design & Execution

• Lead end‑to‑end solution estimation, design and execution for multiple concurrent platform initiatives, from discovery and architecture through development, testing, deployment and transition to operations.
• Provide leadership for major platform modernization and migration initiatives, particularly CMS/DXP, including planning, dependency management, risk resolution and technical transition.
• Develop end‑to‑end solution architectures that connect platforms, custom applications, data, and integration services, ensuring cohesive and scalable designs across teams and vendors, working collaboratively with other architecture subject matter experts within the Applications, Platforms and Data Engineering portfolio.
• Define and apply integration and API patterns (eventing, batch, real‑time), data flows and non‑functional requirements to ensure secure, reliable and maintainable solutions.
• Create and maintain architecture artifacts, including solution diagrams, interface contracts and architecture decisions (ADRs), and ensure they are actionable for delivery and operations teams.
• Ensure non‑functional requirements (security, privacy, performance, availability, observability) are surfaced and designed into solutions and validated through delivery and transition to operations.
• Lead the transition to steady‑state operations post‑deployment or launch.

Technical Leadership & Vendor Engagement

• Provide hands‑on technical leadership across platform engineering, architecture, integrations and implementation decisions.
• Facilitate cross‑team architecture reviews with Application Engineering, Data, Security and Infrastructure & Operations, and drive resolution of technical risks and trade‑offs.
• Manage vendors and external technical partners to ensure secure, high‑quality delivery aligned with scope, budget, timelines and Heart & Stroke standards.

Qualifications

The ideal candidate brings strong experience leading complex platform migrations (particularly CMS/DXP), deep platform engineering and architecture expertise, and the ability to operate across multiple enterprise platforms (including CRM and Salesforce Marketing Cloud) while building and scaling teams in a fast‑evolving environment.
