Role Summary

We are seeking a Senior Software Engineer to design, build, and operate high-throughput, low-latency, mission-critical platforms. 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.

Required Qualifications

·         6+ years Strong Java expertise with experience building production-grade services.

·         6+ years Hands-on API development experience, including RESTful services and API security.

·         Cloud deployment experience on Google Cloud Platform and/or equivalent cloud platforms.

·         2+ Solid experience with Access Management protocols:

o   OAuth 2.0

o   OpenID Connect (OIDC)

o   SAML2.0

·         Proven experience building and operating high-criticality systems with strict SLAs.

·         Strong understanding of distributed systems, concurrency, and performance optimization and resiliency.

·         Experience with observability (metrics, logs, traces) and production troubleshooting.
