Senior Principal - Platform Engineer Voice

Overview

Senior Principal Engineer building and running GSK's voice and unified communications platform as automated, secure, self-service infrastructure, setting the engineering standard and mentoring the engineers around them.

What you'll do

• Design, build and automate platform infrastructure using infrastructure-as-code and golden paths, so that provisioning is repeatable rather than reconstructed each time.
• Use AI-assisted engineering across code generation, review and testing to accelerate delivery and raise quality, reviewing AI-generated output before it is merged.
• Build self-service capabilities and paved roads that reduce friction for consuming teams, so adoption does not depend on the platform team's availability.
• Engineer for reliability by defining SLOs, instrumenting platforms for observability and automating to reduce toil, working with the Site Reliability Engineer on standards.
• Set and uphold engineering standards, secure-by-default practices and code quality within the platform, and hold them in code review.
• Contribute to incident response and drive permanent automated fixes with Reliability Engineering rather than repeating manual recovery.
• Mentor and technically lead other engineers, including partner engineers, linking engineering work to platform OKRs and outcomes.
• Integrate and assure supplier or managed-service components, holding partner-delivered engineering to the same standards and code quality as internal work.
• Work the platform's manual task and toil backlog, converting identified candidates into automation and evidencing the effort removed.
• Close observability coverage gaps for the platform, so that reliability can be measured rather than inferred.
• Contribute engineering-led items to the platform backlog held by the Product Owner, including technical debt, upgrade and automation work, with the cost of not doing them stated.
• Apply the reference architectures and patterns set by the Platform Architect, and raise a case for change rather than diverging locally.

What you'll need

• Degree in a technology or engineering discipline, or equivalent practical experience (e.g., Computer Science, Software Engineering, Electronics).
• Overall 15 years and typically 6-8 years in platform, infrastructure or software engineering, including at least two years as the senior technical voice in a team.
• Deep hands-on depth in the relevant platform domain, whether cloud and hosting, network or digital workplace.
• Practical experience of infrastructure-as-code, for example Terraform, applied to production estates rather than proofs of concept.
• Experience with CI/CD pipelines, and with containers and Kubernetes where relevant to the platform.
• Track record building self-service capability that other teams adopted without hand-holding.
• Experience instrumenting for observability, defining SLOs and reducing toil through automation.
• Experience with AI-assisted engineering tooling, including judgement about when generated output is not fit to merge.
• Extensive experience engineering enterprise voice and unified communications services.
• Strong knowledge of Session Initiation Protocol, call routing, session border controllers, quality of service and high availability.
• Evidence of improving voice quality, resilience, provisioning or operational support.

Nice to have

• Professional level unified communications certification, such as CCNP Collaboration or Microsoft Teams Voice Engineer.
• Relevant technical certifications, such as a recognised cloud certification for AWS, GCP or Azure, Certified Kubernetes Administrator, or a network vendor certification relevant to the platform.
• Experience with cloud calling, contact centre or emergency calling services.
• Experience automating voice provisioning, monitoring or service assurance.
