Senior Salesforce Developer / Admin in Toronto

We are seeking a hands-on Senior Salesforce Developer with strong Marketing Cloud expertise to join our Salesforce Center of Excellence. This is a hands-on solutioning and development role — the successful candidate will personally analyze requirements, design solutions, and build and implement them through configuration and code. Following the partner-led implementation of our Marketing Cloud platform, this role takes technical ownership of the delivered solution — maintaining and operating what has been built, reviewing the implementation against Salesforce best practices, ensuring long-term supportability, and solutioning and implementing ongoing enhancements directly.

Marketing Cloud experience (Marketing Cloud Next, Data Cloud‑native) is a must, and experience with CRM Analytics (CRMA) and Manufacturing Cloud is strongly preferred.

Responsibilities include but are not limited to:

• Personally solution and implement Salesforce changes end to end — analyze requirements, design the solution, and build it hands-on through configuration and code (Apex, Lightning Web Components, flows).
• Serve as the technical lead and senior subject-matter authority for the Marketing Cloud platform, owning technical standards, design decisions, and the enhancement roadmap.
• Take technical ownership of the partner-delivered Marketing Cloud solution — maintaining, operating, and continuously improving it once initial deployment by the external SI is complete.
• Review the delivered implementation against Salesforce best practices, identify gaps or technical debt, and lead remediation to ensure the system is sound, scalable, and supportable.
• Work hands-on in Marketing Cloud Next — building and maintaining segmentation, journeys, content, and activation natively on Salesforce Data Cloud.
• Translate business requirements from stakeholders and the Business Transformation leader into technical designs, enhancements, and new capabilities focused on marketing engagement and customer data.
• Operate and govern sending infrastructure: branded subdomains, domain authentication (SPF/DKIM/DMARC), deliverability, and consent/preference management.
• Maintain and enhance customer data flows and integrations between Marketing Cloud Next, Data Cloud, and source systems (e.g., Microsoft Dynamics 365).
• Own and run a modern Salesforce DevOps practice using Gearset — version control, CI/CD pipelines, automated deployments, environment strategy, and metadata backup/restore.
• Develop and maintain Apex, Lightning Web Components, flows, custom objects, fields, and validation rules according to evolving requirements, applying sound architectural and coding standards.
• Define and enforce development standards, code-review practices, and organization-wide protocols for proper use of Salesforce across teams and partners.
• Maintain system security including sharing rules, role hierarchies, and field-level security, and ensure all changes follow Celestica internal processes.
• Evaluate and operationalize emerging Salesforce capabilities (including Agentforce / AI-assisted marketing), and lead seasonal release readiness across Marketing Cloud and connected clouds.
• Where an external SI is engaged for new workstreams, provide technical oversight, quality-assure delivery, review SOWs, and hold partners to delivery and documentation standards.
• Provide technical direction and mentorship to admins, developers, and analysts within the CoE.
• Create and maintain technical documentation, reports, dashboards, and standard operating procedures.
