Java Developer

As a key member of our engineering team, you will be instrumental in delivering robust solutions that form the backbone of our secure digital ecosystem. You will contribute to critical initiatives by:

• Designing, developing, and maintaining high-performance Java services, focusing on REST-based APIs and leveraging your deep Security SME knowledge.
• Building cloud-native, horizontally scalable services deployed across public cloud platforms.
• Securing APIs using advanced authentication and authorization flows like OIDC, OAuth 2.0, and SAML.
• Implementing API-first designs with stringent contract discipline, ensuring backward compatibility and clarity.
• Constructing and operating highly resilient systems designed for fault tolerance, graceful degradation, and rapid recovery, meeting strict SLAs for latency (< 50ms), throughput (> 5,000 TPS), availability ( 99.9%), and error budgets (< 0.1%).
• Applying advanced resilience patterns including timeouts, retries, circuit breakers, bulkheads, and rate limiting.
• Participating actively in production support, incident response, root cause analysis (RCA), and continuous reliability improvement initiatives.
• Utilizing CI/CD pipelines for automated build, test, and deployment processes.
• Owning the entire build deploy run lifecycle, which includes comprehensive monitoring, alerting, and capacity planning.
• Working with containerized workloads and implementing modern deployment strategies such as blue/green, canary releases, and feature flags.
• Actively leveraging AI-assisted development tools to accelerate feature delivery, enhance code quality, improve test coverage, and assist with refactoring, documentation, and troubleshooting.
• Championing responsible and effective AI usage as an integral part of daily engineering workflows.
• Collaborating seamlessly with platform, security, Site Reliability Engineering (SRE), and product teams to deliver comprehensive end-to-end solutions.
• Contributing significantly to architecture reviews, design discussions, and critical technical decision-making processes.

• 6+ years of strong Java expertise, with proven experience building production-grade services that are highly reliable and performant.
• 6+ years of hands-on API development experience, specifically with RESTful services and robust API security implementations.
• Demonstrated cloud deployment experience on public cloud platforms.
• 2+ years of solid experience with critical Access Management protocols, including OAuth 2.0, OpenID Connect (OIDC), and SAML2.0.
• Proven track record of building and operating high-criticality systems that adhere to strict Service Level Agreements (SLAs).
• Strong understanding of distributed systems principles, concurrency, performance optimization techniques, and system resiliency.
• Extensive experience with observability tools and practices (metrics, logs, traces) and effective production troubleshooting methodologies.
