• Implement API-first designs with stringent contract discipline to ensure backward compatibility.
• Construct and operate highly resilient systems designed for fault tolerance, graceful degradation, and rapid recovery, meeting strict SLAs for latency, throughput, and availability.
• Apply advanced resilience patterns such as timeouts, retries, circuit breakers, bulkheads, and rate limiting.
• Participate actively in production support, incident response, root cause analysis, and continuous reliability improvements.
• Utilize CI/CD pipelines for automated build, test, and deployment processes.
• Own the entire build-deploy-run lifecycle, including comprehensive monitoring, alerting, and capacity planning.
• Work with containerized workloads and implement modern deployment strategies like blue/green deployments, canary releases, and feature flags.
• Leverage AI-assisted development tools to accelerate feature delivery, enhance code quality, and improve test coverage.
• Collaborate seamlessly with platform, security, Site Reliability Engineering (SRE), and product teams to deliver comprehensive end-to-end solutions.

What You'll Bring

• 6+ years of strong Java expertise, with proven experience building production-grade, highly reliable, and performant services.
• 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 SAML 2.0.
• 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.
