About the role and team: You'll join our AI Platform Engineering team, which builds and runs the infrastructure connecting CreateFuture's engineers and client workloads to multiple LLM providers — from the inference control plane (the API gateway and routing layer for Anthropic, AWS Bedrock, OpenAI, and others) through to the orchestration and lifecycle tooling that turns individual AI integrations into a reusable 'capability marketplace', and the trust, safety, and governance controls that keep it all auditable as it scales. We're hiring across this team at several levels — Principal, Senior, and Mid: Principal engineers set technical direction for the platform and act as a trusted extension of the CreateFuture leadership team day to day; Senior engineers own delivery of key platform components, from the gateway through to orchestration; and Mid-level engineers build hands-on experience across the gateway, orchestration, and governance layers, with support from senior colleagues. What you'll be doing: Build, run, and evolve the API gateway and routing layer connecting engineers and client workloads to multiple LLM providers (Anthropic, AWS Bedrock, OpenAI), including the failover and routing strategies you may need to defend in an incident. Design and build orchestration and lifecycle management for AI capabilities and agents, including the tooling that lets teams register, discover, and reuse capabilities rather than rebuilding them. Implement and maintain RBAC/OIDC access controls and disciplined API key lifecycle management across the platform. Build caching layers and cost/latency optimisation strategies, and the adoption and reuse analytics that show whether the platform is actually being used.
