This role focuses on Java-based API development, cloud-native deployments (Google Cloud Platform or equivalent), modern access management protocols, and AI-assisted software development. You will own services with strict reliability, performance, and availability SLAs, operating at scale in a security-sensitive environment. Key Responsibilities: Core Engineering · Design, develop, and maintain high-performance Java services supporting REST-based APIs & having good Security SME knowledge. · Build cloud-native, horizontally scalable services deployed on Google Cloud Platform and/or other public cloud platforms. · Develop and secure APIs using OIDC, OAuth 2.0, and SAML-based authentication and authorization flows. · Implement API-first designs with strong contract discipline, backward compatibility, and understandability. Scale, Performance & Reliability · Build and operate highly resilient systems with: o API latency SLA < 50ms o Throughput > 5,000 TPS o Availability 99.9% o Error budget < 0.1% · Design for fault tolerance, graceful degradation, and fast recovery. · Apply resilience patterns such as timeouts, retries, circuit breakers, bulkheads, and rate limiting. · Participate in production support, incident response, RCA, and continuous reliability improvement. Cloud & Deployment Use CI/CD pipelines for automated build, test, and deployment. Own build * deploy * run lifecycle, including monitoring, alerting, and capacity planning. Work with containerized workloads and modern deployment strategies (blue/green, canary, feature flags). AI-Enabled Development · Actively use AI-assisted development tools (e.g., Copilot in agentic mode) to: o Accelerate feature development o Improve code quality and test coverage o Assist with refactoring, documentation, and troubleshooting · Champion responsible and effective AI usage as part of daily engineering workflows. Collaboration · Partner with platform, security, SRE, and product teams to deliver end-to-end solutions. · Contribute to architecture reviews, design discussions, and technical decision-making.
