Oracle Cloud Infrastructure (OCI) is looking for a Senior Platform Software Engineer to join the PKI team responsible for building and operating cloud-scale Public Key Infrastructure services. In this role, you will design, develop, test, and deliver secure, highly available, and scalable software that manages certificates, cryptographic keys, and trust infrastructure across OCI.

You will work closely with senior engineers, security teams, and partner service teams to deliver new capabilities, improve reliability and operational excellence, and contribute to the evolution of OCI's security platform. The ideal candidate has strong software engineering fundamentals, experience building distributed systems, an interest in applied cryptography and cloud security, and enjoys solving complex engineering challenges at cloud scale.

Responsibitities:

• Design, develop, and operate highly available, secure, and scalable distributed services that power Oracle Cloud Infrastructure's Public Key Infrastructure (PKI), including certificate lifecycle management, key management, trust services, and cryptographic infrastructure.

• Own and evolve a bounded platform component or service, defining APIs and service contracts that support secure, multi-tenant cloud deployments while maintaining backward compatibility.

• Design software solutions that meet business, security, operational, and performance objectives, driving technical design discussions from concept through production deployment.

• Lead feature design reviews, technical documentation, and implementation planning while partnering closely with Product Management and cross-functional engineering teams throughout the feature lifecycle.

• Build robust, maintainable, and well-tested software using object-oriented programming languages such as Java, C++, C#, or similar, following modern software engineering best practices.

• Apply strong knowledge of distributed systems, operating systems, algorithms, and data structures to solve complex engineering problems involving scalability, resiliency, and performance.

• Design and optimize APIs, service integrations, and platform interfaces with a focus on versioning, interoperability, security, and long-term maintainability.

• Develop resilient cloud services by implementing fault tolerance, observability, performance optimization, capacity planning, and automated recovery mechanisms.

• Troubleshoot complex production issues through deep debugging, root cause analysis, and compatibility-safe remediation plans across distributed service environments.

• Improve platform reliability through automation, monitoring, metrics, logging, dashboards, and operational tooling that reduce operational toil and enhance service health.

• Participate in on-call rotations, incident response, operational reviews, and postmortem activities while driving continuous improvements to availability, resiliency, and operational excellence.

• Collaborate with engineers across OCI to integrate PKI capabilities with cloud services, ensuring secure communication, authentication, and trust across the platform.

• Design and implement solutions leveraging relational databases, NoSQL systems, distributed storage, and persistence technologies to support highly scalable cloud services.

• Contribute to the evolution of OCI's multi-tenant cloud platform by building secure, scalable infrastructure components and improving platform architecture.

• Lead code reviews, mentor peers, and promote engineering best practices, secure coding standards, comprehensive testing, and high-quality technical documentation.

• Perform regular maintenance activities, including security updates, vulnerability remediation, certificate lifecycle operations, and platform upgrades while ensuring minimal customer impact.

• Independently manage technical deliverables, prioritize competing work, identify risks early, and collaborate across teams to deliver high-quality solutions on schedule.

• Continuously improve engineering processes, development workflows, automation, and platform capabilities while staying current with emerging technologies, cloud infrastructure, distributed systems, and applied cryptography.
