• Conduct code reviews, provide technical guidance, and mentor junior and mid-level engineers to promote engineering excellence.

• Identify and address application vulnerabilities, performance bottlenecks, and technical debt through proactive improvements and code refactoring.

• Develop comprehensive unit tests, integration tests, and automated testing frameworks to ensure application quality, reliability, and security.

• Support containerized applications and cloud-native deployments using Docker, OpenShift, and enterprise infrastructure platforms.

• Troubleshoot complex production issues, perform root cause analysis, and implement sustainable solutions to improve system stability and availability.

• Participate in production support activities and ensure the ongoing availability, resilience, and security of critical identity management services.

• Continuously evaluate emerging technologies, security frameworks, and software engineering practices to improve enterprise identity solutions.

• Promote collaboration across teams, influence technical decisions, and challenge existing approaches to deliver innovative, secure, and scalable solutions.

• Bachelor's degree in Computer Science, Information Systems, Software Engineering, or a related technical field, or equivalent professional experience.

• 5+ years of professional software development experience, with strong expertise in Java and enterprise application development.

• Extensive experience designing and building scalable, distributed applications and microservices using Java, Spring Boot, and related technologies.

• Strong understanding of object-oriented programming, data structures, algorithms, software design patterns, and clean code principles.

• Experience designing, developing, and integrating RESTful APIs and enterprise web services.

• Solid understanding of secure software development practices, application security principles, and enterprise security requirements.

• Experience working with authentication, authorization, access management, or Identity and Access Management (IAM) concepts.

• Knowledge of modern authentication and authorization standards and protocols, such as OAuth 2.0, OpenID Connect (OIDC), SAML, or JWT.

• Experience with automated build, deployment, and release management tools such as Maven, Git, Jenkins, and CI/CD pipelines.

• Experience with relational and/or NoSQL databases and their integration with enterprise applications.

• Strong troubleshooting, debugging, performance optimization, and problem-solving skills.

• Experience with unit testing, integration testing, test automation, and software quality assurance.

• Ability to independently lead technical initiatives, contribute to architecture discussions, and deliver complex engineering solutions.

• Strong communication and collaboration skills, with the ability to work effectively across engineering, security, and infrastructure teams.

• Proactive mindset focused on continuous improvement, innovation, security, and operational excellence.

• Preferred Qualifications
   

• Hands-on experience with enterprise Identity and Access Management platforms and identity security solutions.

• Experience integrating applications with identity providers, authentication services, and access management systems.

• Familiarity with identity lifecycle management, provisioning, access governance, and privileged access management concepts.

• Experience implementing OAuth 2.0, OpenID Connect, SAML, JWT, and secure API authentication mechanisms.

• Experience with Docker, Kubernetes, and OpenShift-based application deployments.

• Experience developing and maintaining cloud-native applications in enterprise environments.

• Knowledge of security principles such as Zero Trust Architecture, least privilege, and defense in depth.

• Experience with observability, application monitoring, logging, and production incident management.

• Familiarity with DevSecOps practices, automated security scanning, and vulnerability remediation.

• Experience mentoring engineers, conducting technical reviews, and driving engineering best practices across teams.
