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
