Key Responsibilities

• Provide end-to-end technical ownership for Tait’s voice services, ensuring architectural coherence, quality, and long-term maintainability.
• Act as the technical authority for voice-related architecture, design decisions, and engineering practices.
• Collaborate with engineers, Product Managers, and Solution Architects to translate product requirements into deliverable technical solutions aligned with organisational strategy.
• Identify and resolve complex problems within the voice stack architecture, guiding the applications team through design, implementation, and delivery challenges.
• Lead application enablement for voice services, including Tait’s in-house house Push to Talk over Broadband solution and integration with selected third-party voice applications and services.

• Identify and proactively manage technical risks related to scalability, operability, security, and maintainability within the voice domain.
• Act as a senior technical authority and mentor, setting engineering standards, reviewing designs, and supporting the development of high-quality engineering practices across the voice services team.

About You

• You are an outstanding senior engineer and technical leader, recognised for your ability to operate across complex communications systems and drive quality outcomes across the full product lifecycle.
• You bring a deep understanding of voice architectures and are comfortable owning difficult technical decisions in a fast-moving, delivery-focused environment.
• Proven experience designing and delivering complex voice or communications software solutions across the full development lifecycle.
• Deep familiarity with voice stack architectures, VoIP, PTT, or equivalent communications protocols and application enablement frameworks.
• Strong architecture and design evaluation skills, including the ability to compare design approaches and assess long-term impacts on quality, scalability, and maintainability.
• The ability to debug, diagnose, and resolve complex technical issues within voice systems, and to guide others in correcting faulty designs.
• Confidence to review and critique designs, and to train and mentor others in sound engineering and design practices.
• Experience working with or overseeing externally developed software, with a strong focus on quality, sustainability, and retention of system knowledge.
• Comfort working collaboratively across engineering, product, and architecture functions, balancing hands-on technical leadership with the need to align designs to agreed guardrails and long-term technology direction.
