What You'll Do

  • Define and evolve the interaction models, task flows, and usability foundations of Sangoma’s phone firmware and device interfaces.
  • Provide UX design for desk phones (embedded, hardware-constrained products) with physical keys, small and/or touch screen displays.
  • Define task flows and interaction patterns for telephony features such as calling, transfers, conferencing, voicemail, etc.
  • Create UX and UI artifacts including user flows, wireframes, and interaction specifications, icons, and graphics.
  • Produce clear interaction specifications and design documentation to support long development and maintenance cycles.
  • Collaborate closely with firmware engineers to ensure UX designs are accurately implemented.
  • Partner with Product Management to align UX decisions with real-world user needs and business priorities.
  • Identify edge cases, error states, and recovery paths to ensure reliability under real usage conditions.
  • Contribute to usability testing and incorporate feedback into iterative UX improvements.
  • Ensure designs/implementations support all corporate and regulatory standards.
  • Advocate for usability, consistency, and simplicity across Sangoma’s device ecosystem.

What We're Looking For

  • Minimum 3 years of experience (5+ years preferred) in UX and user interface design, product design, or interaction design.
  • 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.

Nice to Have

  • Experience with telephony, VoIP, or enterprise communications products.
  • Experience designing 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.

Team & Environment
