Senior Software Engineer (Platform Cryptography)

• 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
• 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
• 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

Benefits

• Generous family leave
• Matched donations
• Annual learning stipends
• Flexible PTO
• Competitive retirement plan
• Paid volunteer time- Hands-on experience deploying and operating services on Kubernetes in a SaaS/multi-tenant environment
• 4+ years professional software engineering experience; Java, Go, or equivalent OO language at production scale
• Demonstrated capability to manage multiple projects with material technical risk across teams and processes
• Demonstrated security-conscious coding habits: secure coding, code review, unit testing, automation
• Working knowledge of core cryptographic primitives (symmetric/asymmetric encryption, hashing, digital signatures, PKI/TLS fundamentals)
• Familiarity with distributed systems concepts — resource isolation, concurrency, and scaling execution across shared infrastructure
• Advanced knowledge of data structures, algorithms, object-oriented design, design patterns, and performance/scale considerations
• Direct experience with cryptography, PKI, key management, or secrets management systems
• Some applied ML/AI exposure — anomaly detection, classification, or critically integrating AI tooling into engineering workflows — over pure research background
• Experience building distributed backend systems (microservices, SQL/NoSQL data stores)
• Exposure to regulated environments (FIPS 140-2/3, FedRAMP, or similar)
