Platform Engineer – AI & Agent Platforms

What’s the role?

We’re looking for two Platform Engineers to design, build and scale enterprise-grade AI platform capabilities, with a strong focus on agent-based systems and orchestration.

These roles sit at the core of our AI Control Plane initiative—enabling teams to build, deploy and operate AI agents and AI-powered services safely, reliably and at scale. You will play a key role in engineering reusable platform capabilities that support agent design, execution, lifecycle management and governance.

This is a hands-on role combining platform engineering, distributed systems thinking and practical experience building production-ready AI agents.

What do I need?

Strong software engineering experience building distributed, production-grade systems

Proven experience designing and implementing AI agents or orchestration-based systems

Hands-on experience with:

LLM integration and APIs

Retrieval-Augmented Generation (RAG)

Agent frameworks and orchestration patterns

Workflow composition and tool integration

Experience building platform abstractions (APIs, SDKs, shared services)

Strong understanding of production engineering practices (resilience, monitoring, incident response)

Ability to balance trade-offs between performance, latency, cost and risk

Additionally, you’ll bring:

Experience with AI control planes, gateways or multi-model routing (desirable)

Exposure to evaluation, benchmarking or prompt lifecycle practices

Understanding of security, compliance and responsible AI controls

Familiarity with event-driven architectures and open standards

What success looks like:

Scalable, reusable AI agent capabilities adopted across multiple teams

Reliable, observable and production-ready AI systems

Platform-led delivery reducing bespoke implementations

Strong governance and risk controls embedded into AI solutions

Improved developer productivity through consistent tools and patterns

Continuous improvement driven by performance data, evaluation and iteration
