Job summary

ServiceNow is seeking a Senior Software Engineer, Core Cryptography, to design and build secure cryptographic services for a large‑scale multi‑tenant SaaS platform. You will contribute to key management, PKI, and secrets with a security‑first mindset and apply ML/AI to strengthen detection of misuse.

You will collaborate with security architects and engineering teams, operate services on Kubernetes, and stay current on cryptographic advancements including post‑quantum readiness.

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 across shared infrastructure
• Demonstrated capability to manage multiple projects with material technical risk across teams and processes
• 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 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.
