AI Infrastructure Engineer — Agentic AI Platform

Flexhire is a stealth-mode startup building an operating system for AI-agent-driven computing and wearable technology. The Lead Infrastructure Engineer will build and operate the infrastructure powering low-latency, secure, and scalable AI workloads, including CI/CD, Kubernetes, observability, security, infrastructure as code, and cloud-to-edge architecture.

Responsibilities:

• CI/CD pipelines — the automated build, test, and deployment infrastructure that lets a distributed engineering team across Silicon Valley, Paris, and Shenzhen ship confidently and quickly
• AI workload infrastructure — the compute, networking, and storage configurations that support LLM inference, embedding generation, vector search, and RAG pipelines at low latency and meaningful scale
• Kubernetes cluster management — provisioning, scaling, and operating containerized services across cloud environments, with particular attention to the cost and latency tradeoffs of AI workloads
• Observability and monitoring — the logging, metrics, alerting, and tracing systems that give the engineering team full visibility into platform behavior in production
• Security and compliance infrastructure — the systems that enforce our privacy-by-design architecture, including encrypted data pipelines, secrets management, network security, and access controls
• Infrastructure as code — Terraform, Helm, ArgoCD or equivalent, ensuring the entire infrastructure is reproducible, version-controlled, and auditable
• Edge and on-device infrastructure planning — as the platform transitions from cloud-first to edge-first over the next 12 to 18 months, you will be the person who designs the infrastructure architecture that supports that transition
