The Siroky Group Inc. (TSG) is a Canadian software development and consulting company specializing in technology solutions for the Out-of-Home advertising industry.

As we continue to modernize and expand our enterprise software platforms, TSG is looking for a UX/UI Designer to join our product development team.

The successful candidate will initially work alongside a Senior UX/UI Designer on a significant enterprise modernization initiative involving campaign planning, inventory management, mapping, pricing, contracts, operational workflows and dashboards. Over time, the role will expand across TSG's broader suite of web and mobile applications.

This is not a marketing website or consumer application design role. Our applications support complex business processes and information-heavy workflows. We are looking for someone who is interested in understanding how people actually use software to do their jobs and finding ways to make those experiences simpler, clearer and more efficient.

The Role

Working closely with our Senior UX/UI Designer, Product Owners, Business Analysts, developers, QA team and client subject-matter experts, you will help transform complex existing workflows into modern, intuitive web and mobile experiences.

Initially, you will work under the UX direction established for a major enterprise modernization project, taking ownership of increasingly significant functional areas as your knowledge of our products and industry grows.

As the role develops, you will become an important part of TSG's internal UX capability and will contribute to the continued modernization of products across our application suite.

• Prepare development-ready designs, specifications and supporting documentation.
• Participate in design reviews with internal teams, clients and business users.
• Incorporate feedback from users, Product Ownership, development and QA into design iterations.
• Review implemented functionality for consistency with approved designs and established UX standards.
• Support usability testing, UAT and ongoing product refinement.
• Consider accessibility, usability and responsive behaviour throughout the design process.
• Gradually assume greater ownership of UX/UI design across TSG's enterprise product suite.

What We're Looking For

• Experience designing enterprise, B2B, SaaS or other workflow-driven applications.
