## Job Description

## Responsibilities
- Architect and implement production-grade security services (e.g., auth services, access brokers, secure proxies, key-management infrastructure) that provide strong guarantees across hardware, operating systems, Kubernetes, networks, and CI/CD.
- Partner with infrastructure and research engineers to embed security into high-performance compute clusters, enabling rapid model training and deployment without compromising protection.
- Develop automation and detection tooling to continuously identify and mitigate risks in large-scale cloud and on-prem environments.
- Drive high-impact initiatives such as line-speed encryption, machine identity, and network isolation, continuously raising the security bar for emerging AI workloads.
- Lead or participate in design reviews and threat models to ensure new systems launch with strong security foundations and operational excellence.

## Requirements
- Strong software engineering skills in languages such as **Python**, **Go**, **Rust**, or **C/C++**, with a track record of shipping and operating high-reliability distributed services.
- Experience building or operating critical security infrastructure (e.g., auth services, service-to-service proxies, certificate or key-management systems).
- Deep understanding of security principles, best practices, and common vulnerabilities.
- Expertise in securing large-scale cloud platforms (e.g., **Azure**, **AWS**, **GCP**), including multi-cloud networks and cloud-agnostic system design.
- Familiarity with container and orchestration security (**Kubernetes**, service meshes) and modern authentication/authorization standards (**OIDC**, **mTLS**, **SPIFFE/SPIRE**).
- A proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
- A track record of delivering scalable solutions and driving impactful changes across infrastructure in real-world projects.
- Strong analytical and problem-solving skills, with an ability to think critically and objectively assess security risks.
- Excellent communication skills, with the ability to convey complex security concepts to technical and non-technical stakeholders.
