Senior Software Engineer - Cloud

You will design, develop, and maintain core cloud platform services including compute orchestration, resource management, multi-tenancy, and API gateway components. You'll build and optimize RESTful/gRPC APIs and microservices supporting cloud resource provisioning, lifecycle management, and monitoring. You'll develop scalable, fault-tolerant distributed systems handling high-throughput workloads across multi-region deployments, and implement service mesh, rate limiting, authentication, and authorization mechanisms. You'll write clean, well-tested, well-documented code following best practices like CI/CD, code review, and TDD. On the infrastructure side, you'll design cloud-native architectures using Kubernetes and Docker, build Infrastructure-as-Code solutions, optimize CI/CD pipelines, and implement service discovery, configuration, and secrets management. You'll design data access layers and storage solutions across relational, NoSQL, and caching systems, optimizing queries and implementing migration and backup strategies. You'll implement observability solutions including distributed tracing, structured logging, and metrics collection, build alerting and SLI/SLO frameworks, and participate in on-call rotations and incident response. You'll collaborate across teams to define technical requirements, participate in architecture and code reviews, mentor junior engineers, and evaluate new technologies to improve the platform.
