Sr Software Engineer, Platform Cryptography
Job Description
Team
Platform Security builds foundational security infrastructure and AI-driven detection systems for enterprise-scale operations. Our mission is to make security proactive, intelligent, and seamlessly integrated into the ServiceNow platform. Cryptography within Platform Security owns the cryptographic backbone of the ServiceNow platform across multiple domains: certificate lifecycle, key management, secrets distribution, and workload identity for a SaaS platform. This is core, regulated-environment security engineering
Role Summary
As a Senior Software Engineer, Core Cryptography, you will design and build secure, high-quality cryptographic services — key management, PKI, secrets — for a large-scale multi-tenant SaaS platform. You will bring hands-on engineering depth, a security-first mindset, and the ability to apply ML/AI techniques to strengthen how the system detects misuse and anomalies, working under the technical direction of staff+ engineers on the team.
What You Get to Do in This Role
• Design, develop, and maintain high-quality, secure cryptographic services meeting FIPS compliance and regulated-environment requirements
• Build and operate services within the core crypto ecosystem — key management, certificate lifecycle, secrets distribution — with reliability and security as first-class requirements
• Apply ML/statistical techniques where they add real value — flagging anomalous key usage, abnormal secrets access, or unusual certificate request patterns
• Contribute to building inference/detection pipelines that surface cryptographic misuse or compromise indicators in near real time
• Collaborate with product owners, security architects, and engineering teams to translate security and compliance requirements into working code
• Operate services on Kubernetes in a multi-tenant SaaS environment — deployment, CI/CD, on-call, incident response
• Write secure code by default: threat-model your own designs, review others' code with the same rigor, catch logic errors and cryptographic anti-patterns
• Stay current on cryptographic advancements, including post-quantum readiness, and bring relevant ideas to the team
