Responsibilities:

• Own the end-to-end UX of Sangoma’s desk phone and device experiences, from interaction models to execution
• Design for embedded, hardware-constrained environments with physical inputs, limited screens, and real-time expectations
• Define task-driven workflows for core telephony functions: calling, transfers, conferencing, voicemail, call handling, and more
• Create clear, scalable interaction patterns that prioritize speed, predictability, and low cognitive load
• Translate complex communication workflows into simple, intuitive user experiences
• Develop UX artifacts including flows, wireframes, interaction specs, and system behaviors
• Partner closely with firmware engineers to ensure designs are implemented accurately and perform reliably in production
• Work with Product to align UX decisions with real-world usage, customer needs, and business outcomes
• Anticipate edge cases, failure states, and recovery paths in real-time communication scenarios

• You are naturally curious, eager to learn, and motivated to understand how design decisions translate into real behavior
• Demonstrated experience designing, task-focused, workflow-driven interfaces
• Strong understanding of human–computer interaction (HCI) principles, including cognitive load, affordances, and error prevention
• Comfortable prioritizing clarity, reliability, and speed of use over visual expressiveness when necessary
• Ability to communicate UX rationale clearly to engineers and non-design stakeholders
• Proficiency with design tools such as Figma, Sketch, or similar
• Experience working in cross-functional Agile product teams
• Experience with telephony, VoIP, or enterprise communications products
• Experience designing for constrained or non-traditional platforms, such as embedded devices, hardware products, enterprise tools, or operational systems
• Understanding of localization and internationalization considerations
• Prior exposure to usability testing or field studies in enterprise or operational environments
