About The Job
We are building an enterprise-grade agentic AI platform for a major telecommunications client, focused on network operations. The platform helps operations teams triage events, run diagnostics, and drive incident and change workflows by reasoning over large volumes of internal network knowledge (alarms, tickets, vendor documentation, process data). It is evolving from a single retrieval-augmented assistant toward a multi-agent operations platform with progressively higher levels of autonomy, always under strict human-in-the-loop and data-protection controls. The solution runs on Google Cloud and aligns to the client's central AI engineering and architecture standards.

We are looking for a senior architect to own the end-to-end agentic architecture and steer a nearshore delivery team.

YOUR ROLE

• Design a modular multi-agent architecture (planner, executor, memory, tool interfaces) and the orchestration and task-handoff logic between agents
• Define autonomy levels, decision boundaries, and human-in-the-loop controls for operational use cases
• Architect RAG and long-term memory across multiple enterprise knowledge sources; set model-selection and LLMOps patterns on GCP / Vertex AI (Gemini)
• Embed guardrails, fallback mechanisms, and GDPR / data-protection compliance into the design
• Define the evaluation and safety-testing strategy (task completion, hallucination detection, bias) and the release quality gates
• Steer junior and nearshore developers, review delivery, and uphold architectural standards
• Interface with client stakeholders and the central AI architecture function on standardisation and scale

YOUR PROFILE

• 7+ years in AI/ML, including hands-on GenAI and agentic systems
• Deep, hands-on GCP experience (Vertex AI, Agent Development Kit / ADK), RAG, and LLMOps
• Proven multi-agent and orchestration design
• Strong grasp of guardrails, evaluation, and responsible-AI / data-protection practices
• Able to lead a distributed delivery team and communicate with senior client stakeholders
• Telco or network-operations domain experience a plus

WHAT YOU'LL LOVE ABOUT WORKING HERE:

• Flexible and dynamic work environment involving teams spread across different global locations;
• Communities with shared interests and identities, all working together to advance diversity, equity and inclusion within the workplace and society;
• Do you want to learn more? You will have access to various training programs and platforms (e.g.: content provided by Pluralsight, Harvard and Coursera);
• Attractive benefits package (meal tickets, medical services, Benefit online, Employee Share Option Plan).
