Agentic Platform Engineer

As Agentic Platform Engineer, you will be responsible for building and operating the enterprise agentic engineering platform that enables AI agents to safely plan, reason, use tools and execute work across Travel Counsellors’ technology estate.

This is an agentic engineering role with strong Platform foundations. Your primary focus will be the design, development and production operation of autonomous and semi-autonomous agents for software delivery, platform operations, service reliability, security and engineering productivity. You will create reusable agent capabilities, orchestration patterns, tool integrations, memory and retrieval services, evaluation frameworks and governance controls that allow teams to adopt agentic automation safely at scale.

You will treat agents as production software: versioned, tested, observable, secure, cost-controlled and accountable. Working across Platform Engineering, Architecture, Security, Data and product teams, you will turn high-value operational workflows into reliable agentic products with clear human oversight, measurable outcomes and safe rollback.

Principal Accountabilities

• Design, build and operate the enterprise agentic platform, including orchestration, runtime services, model routing, memory, identity and policy enforcement.
• Develop reusable agent frameworks, SDKs and patterns that enable engineering teams to build secure, scalable AI agents consistently.
• Engineer autonomous and human-in-the-loop agent workflows that plan, execute, validate and escalate tasks within defined risk and governance controls.
• Integrate agents securely with enterprise platforms, cloud services, APIs and knowledge sources using modern integration standards and Model Context Protocol (MCP).
• Build production-grade agent services using Python, cloud-native architectures, event-driven design, automation and Infrastructure as Code.
• Implement robust evaluation, observability and continuous improvement capabilities, including testing, tracing, telemetry and performance optimisation.
• Embed security, governance and responsible AI principles through least-privilege access, policy enforcement, auditability and data protection.
• Own the reliability and operational excellence of the agentic platform, including CI/CD, cloud infrastructure, monitoring, incident response and production support.
• Collaborate with Engineering, Security, Architecture, Data and Risk teams to define standards, document best practices and support adoption of the platform.

• Hands-on experience designing and operating production AI-agent or LLM-powered systems, not only experimenting with chat interfaces or prompt prototypes.
• Strong software engineering capability in Python, including API design, automated testing, asynchronous processing, dependency management and production debugging.
• Practical experience with agent orchestration, structured tool calling, workflow state, retrieval-augmented generation and human-in-the-loop patterns.
• Experience building secure integrations with enterprise APIs, repositories, cloud services, CI/CD, observability or ITSM platforms.
• Experience creating evaluation frameworks for agent quality, task completion, safety, reliability, latency and cost.
• Strong understanding of agent security, including workload identity, least privilege, secrets management, sandboxing, approvals and audit trails.
• Experience observing and operating LLM or agent workloads in production, including tracing, prompt/model/tool versioning, regression monitoring and incident response.
• Strong AWS and cloud-native engineering experience, including Infrastructure as Code, containers or serverless services, networking, IAM and monitoring.
• Experience with CI/CD and production ownership, with willingness and ability to participate in an on-call rota.
• Ability to explain complex agent behaviour, risks and trade-offs clearly to engineering and non-engineering stakeholders.
