  • Develop scripting and automation solutions to streamline cryptographic operations and integrations.

  • Lead and manage projects involving diverse cross-functional stakeholders, ensuring alignment and successful delivery while building deep relationships with product and engineering leaders

  • Stay up-to-date with the latest advancements in cryptography and cybersecurity to continuously improve our security posture.

  • Provide technical leadership and mentorship to junior security engineers and participate in interviewing new talent.

What You’ll Need:

  • Deep expertise in TLS lifecycle management, including Certificate Authority (CA) management, certificate operations, and key rotation.

  • Familiarity with code signing processes and tools.

  • Proven experience with Hardware Security Modules (HSMs) and their integration.

  • In-depth knowledge of cryptographic algorithms, protocols, and standards (e.g., AES, RSA, ECC, SHA-2).

  • Proficiency in scripting and automation to ease cryptographic operations and integrations (e.g., Python, Bash, Go).

  • Experience with Cloud-scale, business-critical Linux and/or other Unix-like variant environments

  • Experience operating at scale and complexity in services and users.

  • Demonstrated ability to run projects with diverse stakeholders and ensure successful delivery in a fast-paced environment with teams that engineer products and bring them to market.

Bonus Points:

  • Experience with private CA design and management.

  • Experience with post-quantum cryptography and knowledge of emerging quantum-resistant algorithms.

  • Experience with compliance frameworks (e.g., NIST, FIPS, PCI-DSS).

  • Familiarity with cloud security and experience securing cloud-based applications and services in AWS, GCP, and/or Azure Cloud environments.
