on sits at the intersection of hands on software development and advanced application support, making it ideal for a developer who enjoys deep technical problem solving and working directly with production systems. Approximately 40 percent of the role focuses on Tier 3 support, where you will investigate complex non routine issues requiring code level analysis, debugging, fixes, and enhancements, while the remaining 60 percent is dedicated to collaborating with the core development team on feature enhancements, backlog initiatives, technical debt remediation, and continuous improvement. The ideal candidate is a strong communicator with a curious and analytical mindset who takes ownership of issues end to end and remains calm under pressure. Experience working in formal support environments is an asset but not mandatory; what matters most is resilience, adaptability, and the ability to diagnose root causes and deliver permanent solutions. This full time role includes a rotating on call schedule, limited after hours incidents, and requires eligibility for Government of Canada security clearance.

•Work with the broader engineering team to deliver patches or hotfixes, ensuring quality and adherence to SLAs.
•Collaborate with customer-facing support teams to gather information, validate issues, and provide timely and detailed updates to stakeholders.
•Write or update code where necessary to improve system stability, performance, and maintainability.
