Role Description

As a Cloud Cryptographic/Key Management Engineer, you will develop solutions to operate in a large-scale infrastructure cloud environment securely supporting Special Operations Command Europe (SOCEUR) Hybrid Threat Action Platform (HTAP). These solutions will facilitate the deployment of software-defined networking, advanced security controls, and cryptographic capabilities to enable cloud usage to be flexible and highly secure. This position will ensure their solutions meet the highest cryptographic standards.

• Specialize in cryptographic solutions, key management, and enterprise security platforms for critical data security services.
• Engineer and develop solutions supporting web and mobile applications, machine learning, and big data, with a strong emphasis on cryptographic integrity and security.

• Build foundational backend services used by Cloud customers and internal Google systems to secure, rotate, and manage cryptographic keys (e.g., Cloud Key Management Service).
• Work across all layers of the production stack, from high-level, customer-facing Cloud APIs down to low-level operating systems and physical hardware.
• Architect and scale HSM (Hardware Security Module) backed services to meet strict enterprise compliance and high-availability requirements.
• Design cryptographic and secret management solutions, manage key lifecycles, and handle encryption schemes (e.g., Customer-Managed Encryption Keys or External Key Managers).
• Design and deploy environments like Confidential VMs and Trusted Execution Environments (TEEs) to protect data while it is in use.
• Design robust, reliable data-centric security and authentication protocols across global, hyper-scale cloud data centers.
• Implement Client-Side Encryption (CSE) for Google Workspace and ensure mutually authenticated TLS 1.3 communications.

Qualifications

• Active Top Secret/SCI
• BS in Computer Science, or equivalent practical experience in data structures and software security.
• 8+ years of industry experience in software development or cloud infrastructure engineering.
• 5+ years of advanced proficiency in general-purpose languages like Python, C, C++, Java, or Go.
• 5+ years’ experience designing and developing large-scale, distributed infrastructure or highly secure operating environments.
• 5+ years’ experience with cryptographic algorithms, Public Key Infrastructure (PKI), TLS/SSL, authentication protocols, and threat modeling.
• 3+ years of Google Cloud Identity, OAuth/SAML, Keycloak, and Google Workspace SSO integration.
• Strong programming proficiency in languages such as C++, Go, or Python.
• At least 3 years of experience in security and cryptographic engineering.
• At least 3 years of experience in Agile team roles supporting security and cryptographic projects.
• At least 3 years of experience with PKI, Key Management, and certificate lifecycle processes.
• GCP Professional Cloud Security Engineer certification.
• GIAC Python & Cryptography (GPCS / GCIP) certification.
• CCSP (Certified Cloud Security Professional) certification.
• CISA (Certified Information Systems Auditor) certification.

Requirements

• 4+ years of experience implementing scalable cloud applications and platform services utilizing cryptographic controls.
• 4+ years of experience using Terraform to codify security and cryptographic infrastructure configurations.
• 4+ years of network or operating system administrative experience focused on security hardening.
• FIPS 140-2/3 validation processes and managing keys in a multi-level security environment, including policies for key generation and rotation.

Benefits

• A culture of integrity.
• An environment of trust.
• A focus on continuous growth.
