The Role- Domain Architect – Autonomous Networks, AIOps & Agentic AI
The Domain Architect will provide architecture leadership and deep domain expertise for BT’s Autonomous Networks, AIOps and AI-led Network Transformation initiative. The role will shape the target-state architecture, guide technology strategy, and ensure alignment with BT’s ambition to progress towards Autonomous Network Level 4+ capabilities. Working closely with BT architects, TCS SMEs, hyperscalers, network vendors and ecosystem partners, the architect will define and validate architecture patterns spanning network operations, AIOps, observability, automation, knowledge management, AI reasoning and agentic orchestration. The role will act as the primary domain expert for Autonomous Networks, ensuring that solutions are standards-based, scalable, vendor-neutral and aligned with industry frameworks.
Your responsibilities:
Key Responsibilities
Architecture Leadership & Solution Strategy:
- Define and evolve the target Autonomous Network and AIOps architecture.
- Establish architecture principles, standards, guardrails and reusable design patterns.
- Drive architecture reviews and technical governance across BT, TCS and partner teams.
- Ensure alignment between business objectives, network transformation priorities and technical architecture decisions.
- Define integration approaches across OSS, automation, observability, AI and orchestration domains.
Autonomous Network Domain Leadership
- Provide deep expertise in Autonomous Network maturity models, intent-based operations, closed-loop automation and domain autonomy.
- Define capability roadmaps supporting progression towards AN Level 4+ objectives.
- Shape architecture patterns for use cases such as predictive operations, anomaly detection, root-cause analysis, closed-loop remediation, service assurance and intelligent automation.
- Support alignment of architecture capabilities with strategic business outcomes and operational transformation goals.
TM Forum & Industry Standards Alignment
- Ensure architecture alignment with TM Forum Autonomous Networks, Open Digital Architecture (ODA), eTOM, SID and Open APIs.
- Promote open, standards-based and vendor-neutral architecture approaches.
- Define architecture principles for interoperability, integration and ecosystem collaboration.
- Support industry-aligned reference architectures and governance frameworks.
