Role Overview

As a Lead AI Platform Engineer, you will design, build, and operate a scalable, production-grade platform for deploying and running autonomous AI agents, including model serving, tool-calling, and state management.

You will develop high-performance, low-latency inference services on GPU/TPU clusters, implement autoscaling with Kubernetes and Knative, and build CI/CD and MLOps pipelines for model versioning, canary releases, and rollback.

You will also contribute to platform reliability, observability, and security, while developing tools that enable internal teams and external partners to efficiently integrate with and use the AI platform. The role combines software engineering, distributed systems, and AI infrastructure, with a strong focus on delivering secure, scalable, and reliable production solutions.

Responsibilities and Duties

• Design and own the core platform that builds, deploys, and runs autonomous AI agents (model serving, tool‑calling, state management).
• Build high‑throughput, low‑latency inference services on GPU/TPU clusters and implement autoscaling with Kubernetes/Knative.
• Create CI/CD & MLOps pipelines for model versioning, canary releases, and rollback.
• Define SLO/SLI, set up monitoring (Prometheus, OpenTelemetry), and lead incident response.
• Implement security controls (IAM, sandboxed execution, data‑residency policies).
• Deliver developer‑friendly SDKs, CLI tools, and documentation for internal teams and external partners.
• Mentor junior engineers and champion best‑practice code standards.

Must-have requirements:

• 7+ years software engineering; 4+ years building large‑scale distributed systems.
• Proficient in Go or Rust and Python; strong Kubernetes, Docker, Helm experience.
• Hands‑on with model serving frameworks (Triton, vLLM, TensorFlow Serving) and GPU/TPU workloads.
• Experience with event streaming (Kafka/Pulsar) and infrastructure‑as‑code (Terraform/Pulumi).
• Solid knowledge of LLM concepts, retrieval‑augmented generation, and tool‑use APIs.
• Strong debugging, observability (Prometheus, Grafana, OpenTelemetry), and security (IAM, Vault) skills.
• Excellent communication and a bias toward shipping reliable, production‑grade code.

Nice-to-have requirements:

• Ph.D./M.S. in CS or related field.
• Experience with serverless runtimes, vector DBs (FAISS, Milvus), or agent frameworks (LangChain, AutoGPT).
• Open‑source contributions in AI/ML infrastructure.
