AI Platform Technical Lead

Job Description

We have a great new role for an AI Platform Tech Lead to join our Technology Transformation Team within CTO.

The AI Platform Technical Lead is the senior technical authority responsible for the design, architecture, and quality of the AI and data platforms that underpin advanced analytics, AIOps, and AI-enabled OSS capabilities across the CTO organisation. Working with the Head of Cloud, Data & AI Enablement, this role ensures that data, cloud, and AI platforms are engineered to be scalable, secure, resilient, and fit for operationalising AI at enterprise scale across fixed and mobile networks.

We require an exceptional candidate with deep hands-on technical leadership and strong solution governance. You will shape the technical foundations required to ingest, process, and expose high-quality network and OSS data, and to operationalise AI/ML models that drive automation, predictive insights, and improved customer experience. Acting as a key design authority, the AI Platform Technical Lead guides internal teams and suppliers through complex delivery, challenges sub-optimal designs, and ensures alignment with strategic architecture, security, and cost objectives.

The must haves

• Strong experience designing and leading AI and data platforms in large-scale, cloud-native environments.
• Advanced data engineering expertise including data modelling, ETL/ELT, orchestration, and real-time streaming (e.g. Kafka, Spark, Flink).
• Proven experience with MLOps and AIOps, including feature pipelines, model lifecycle management, monitoring, and operationalisation.
• Strong cloud engineering background, GCP or similar cloud provider, and experience with Kubernetes, containerisation, and IaC (Terraform, Ansible).
• Solid understanding of telecom network domains (RAN, Core, Transport) and OSS/BSS data sources, including telemetry, alarms, topology, configuration, and service inventory.
