Job summary

ServiceNow is seeking a Senior Software Engineer, Core Cryptography, to design and build secure cryptographic services such as key management, PKI, and secrets for a large-scale SaaS platform. You will apply a security-first mindset and contribute to ML/AI enabled detection within cryptographic workflows.

You will work under technical direction from staff+ engineers, collaborate with product owners and security architects, and operate services on Kubernetes in a multi-tenant environment,

Qualifications

• 4+ years professional software engineering experience; Java, Go, or equivalent OO language at production scale
• Advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations
• Familiarity with distributed systems concepts — resource isolation, concurrency, and scaling execution across shared infrastructure
• Hands-on experience deploying and operating services on Kubernetes in a SaaS/multi-tenant environment
• Working knowledge of core cryptographic primitives (symmetric/asymmetric encryption, hashing, digital signatures, PKI/TLS fundamentals)
• Demonstrated security-conscious coding habits: secure coding, code review, unit testing, automation

Responsibilities

• Design, develop, and maintain 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
