Working ability in both is strongly preferred, since the pod maintains Python services while building new development on .NET. * Demonstrated experience with high-throughput ingestion and event processing in production. * Hands-on caching experience with Redis or equivalent, including invalidation and read-path tuning. * API design at scale, including contract design, versioning, and performance under real consumer load. * Strong data modeling skills across relational and event-shaped or time-series data. * Experience in creating and implementing well-tested, scalable, and performant enterprise-level systems. * Expertise in applying object-oriented programming principles, plus good understanding of SOLID principles and familiarity with OWASP. * Experience in Agile software development methodologies. * Proficiency in the English language. * Must be authorized to work in the United States., * ServiceNow or CMDB familiarity. This is preferred rather than required. * Experience decomposing a legacy service into smaller services while it stays in production. * Containers and orchestration using Docker and Kubernetes. * Architectural patterns such as microservices and event-driven design, and design patterns such as factory, singleton, and observer. * Object-Relational Mappers (ORMs) and unit testing practice. * Experience with CI/CD pipelines and cloud native application patterns. * Prior data center, DCIM, or IT operations data background. ## Description * Independently drive project delivery within defined architecture, demonstrating autonomy and accountability in all stages from conceptualization to deployment. * Build and operate high-throughput ingestion and event processing services that consume the upstream telemetry stream. * Implement contextualization logic that joins telemetry against CMDB, asset, and other reference data, and the data models behind it. * Design and implement APIs and telemetry feeds at scale, including pagination, filtering, contract stability, and versioning. * Implement and tune caching with Redis or equivalent, including invalidation strategy and read-path performance. * Contribute to the decomposition of existing Python services into well-bounded services, largely on .NET going forward. * Craft client code that is not just efficient but also performant, testable, scalable, secure, and of the highest quality. * Actively participate in accurate planning and estimation efforts, utilizing project methods and tools. * Take part in knowledge transfer from the outgoing delivery team and help ramp up engineers joining behind you. * Engage in agile software development, including daily stand-ups, sprint planning, team retrospectives, and other governance activities. * Actively participate in the Engineering Practice community, mentoring others through Communities of Practice (CoPs) or on project teams and supporting the growth of technical capabilities.
