- Develop applications that integrate with Hardware Security Modules (HSMs) using PKCS#11.
- Implement cryptographic functionality using RSA, ECC, and AES.
- Develop secure services using C#, .NET Core, Java, Python, or similar object-oriented languages.
- Deploy and maintain applications in cloud and on-premises Kubernetes/OpenShift environments.
- Work with databases including PostgreSQL, MongoDB, Redis, Oracle, or MySQL.
- Implement secure authentication and access control using OAuth and mTLS.
- Apply secure coding practices and software architecture principles.
- Promote test-driven development (TDD), CI/CD, automated testing, and Agile development.
- Monitor application health, performance, security, and reliability.
- Support SAST, DAST, vulnerability scanning, and security remediation activities.
- Apply cybersecurity standards and best practices including NIST, OWASP, ISO, and IEEE standards.
- Collaborate with architects, product owners, developers, security teams, and customers.
- Own products and services through the complete lifecycle, from requirements gathering through deployment and post-production support.
