Located in the Bellevue Office (with required presence 4 days per week), this Staff Security Architect role at Lambda involves shaping overall security architecture with a focus on data protection and platform security. This position suits an experienced security professional with a strong background in cloud-scale infrastructure protection and data lifecycles.

Role Overview

Lambda is seeking a Staff Security Architect to report to the CISO and define secure-by-default foundational patterns across core AI infrastructure, hardware and GPU platform layers, multi-cloud control planes, and end-to-end data lifecycles. The role focuses heavily on data protection, cryptographic key management, platform security, and pioneering AI-driven security architecture capabilities.

Key Responsibilities

Architect, design, and standardize end-to-end data protection strategy, including data classification, KMS/HSM, DLP, and privacy-preserving controls.
Define data lifecycle security controls for training datasets, checkpoint storage, and model artifacts.
Drive confidential computing architectures, envelope encryption, and hardware-backed data security guarantees.
Establish zero-trust data access policies and fine-grained authorization frameworks for sensitive platform APIs.
Design and enforce core platform security architectures across multi-tenant GPU infrastructure, bare-metal clusters, hypervisors, and Kubernetes.
Define strong tenant isolation, sandboxing, and secure virtualization controls to prevent side-channel and platform escape vulnerabilities.
Conduct threat models, architectural reviews, and risk assessments for core platform services.
Prototype security controls in Python or Go.
Pioneer AI-powered architectural security capabilities leveraging Lambda's hosted LLMs for automated threat modeling and policy validation.
Partner with engineering and product leaders to embed security architecture into long-term product roadmaps.
Mentor senior engineering talent on secure design principles.

Requirements

10+ years of total engineering experience with 5+ years specializing in security architecture, platform security, or data protection at cloud or infrastructure scale.
Deep expertise in data security concepts including KMS/HSM, cryptographic protocols, DLP, and confidential computing primitives.
Proven track record of designing multi-tenant platform security architecture across heterogeneous infrastructure such as bare-metal GPU clusters, hypervisors, KVM, Kubernetes, and public cloud.
Strong technical skills in prototyping security designs and reference code in Python, Go, or similar languages.
Demonstrated experience with threat modeling methodologies like STRIDE and PASTA.
Strong communication and stakeholder management skills.
Ability to balance robust enterprise security controls with employee experience and productivity.
Experience thriving in fast-moving, high-growth startup environments.

Nice to Have

Excitement about leveraging direct access to state-of-the-art LLMs to revolutionize enterprise security.
Experience building enterprise security and IAM programs at high-growth tech companies or cloud providers.
Familiarity with compliance frameworks such as SOC 2, ISO 27001, FedRAMP, and HIPAA.
Experience implementing Infrastructure as Code using Terraform.
