About the role
- In this role, you'll work across compute, storage, networking, and data platforms, making sure our systems are secure, reliable, and built to scale.
- You'll shape controls, architecture, and tooling so that security is part of how the platform works by default.
- Note: This is an "evergreen role" that we keep open on an on-going basis to express interest.
Responsibilities
- Manage identity, access, and secrets for humans and services: workload and cross-cloud identity, least-privilege IAM, and secrets management.
- Build secure platforms for data ingestion, processing, and curation: classification, encryption, access controls, and safe sharing patterns across teams.
- Write threat models and review designs with researchers and engineers to help them ship features and experiments in a safe, scalable way.
- Automate security checks and build guardrails: policy-as-code, secure infrastructure baselines, validation in CI/CD, and tools that make the secure path the easiest one.
Requirements
- Bachelor's degree or equivalent experience in engineering, or similar.
- Practical experience with Infrastructure as Code (Terraform or similar), including secure patterns for provisioning networks, IAM, and shared services.
- Proficiency with a systems language such as Rust and scripting in Python for building platform components and internal tools.
- Experience with ML infrastructure, GPU clusters, or large-scale training environments (schedulers, job queues, shared storage, multi-tenant clusters).
- Experience profiling and tuning high-throughput systems, and an ability to reason about the cost of additional security layers.
- Familiarity with securing specialized hardware (GPUs, TPUs) and their integrations into training and inference pipelines.
