Metrolinx is connecting communities across the Greater Golden Horseshoe. Metrolinx operates GO Transit and UP Express, as well as the PRESTO fare payment system. We are also building new and improved rapid transit, including GO Expansion, Light Rail Transit routes, and major expansions to Toronto’s subway system, to get people where they need to go, better, faster and easier. Metrolinx is an agency of the Government of Ontario.

At Metrolinx, equity, diversity and inclusion are essential to living our values of serving with passion, thinking forward and playing as a team.

This role is an in‑office position based at our 277 Front Street West office location. Our team is highly collaborative, and much of our work benefits from in‑person co‑creation, relationship‑building, and hands‑on partnership with leaders across the organization.

We are seeking a Senior Software Developer (Integrations) to design, develop, and deliver scalable, high-performing integration solutions across enterprise systems. This role supports critical platforms within Transit Operations and enterprise technology portfolios by enabling real-time interoperability, API development, and cloud-based integrations. The ideal candidate brings strong technical leadership, hands-on development expertise, and the ability to translate business needs into robust technical solutions.

What will I be doing?

Design, develop, test, and implement integration solutions, APIs, and enterprise applications aligned with SDLC best practices
Lead technical analysis, architecture, coding, and deployment of scalable and secure systems
Develop and maintain system integrations across cloud and on-premise environments
Define and document technical specifications and interface designs
Collaborate with cross-functional teams, stakeholders, and vendors to deliver solutions
Ensure solutions align with enterprise architecture, cybersecurity, and data governance standards
Lead code reviews, quality assurance, and troubleshooting activities
Mentor junior developers and promote best practices in software development
Support continuous improvement, performance optimization, and system reliability

What Skills and Qualifications Do I Need?

Education & Experience

Degree in Computer Science, Engineering, or related field (or equivalent experience)
Demonstrated years of experience in software development, including technical leadership roles.

Technical Skills

Strong experience in integration development (APIs, microservices, event-driven architecture)
Proficiency in technologies such as C#, .NET, Node.js, JavaScript frameworks, SQL, Redis, SignalR, RESTful and SOAP services
Experience with cloud platforms (Azure Container App, ACR, Azure Functions, Key Vault preferred) and DevOps/CI-CD pipelines
Knowledge of security protocols (OAuth2, SAML, encryption) and API management
Experience with messaging/event streaming (e.g., Azure Event Hub, Service Bus, RabbitMQ)
Familiarity with Agile methodologies.

Additional Assets

Experience with enterprise systems, data platforms, or real-time integrations
Certifications such as Microsoft Certified Developer or Agile/Scrum credentials
