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
