Backend Senior Software Engineer

Position Summary...

What you'll do...

As a systems telemetry senior software engineer, you will be a key developer in the development of telemetry designs, managed services, and real-time telemetry software systems. You will use your depth of engineering and experience to assist in software initiatives, proof of concepts, analysis of software products, and real-time metric and data system designs.

This role will involve collaboration with the business partners, product managers and representatives from other engineering disciplines. Specifically, you will work with enterprise architects, product owners, data scientists, engineers, and business managers to bring telemetry R&D projects into production. To achieve this effect, you will use a combination of open source and COTS technologies to solve real-time telemetry problems at an enterprise wide scale. Furthermore, you will work on Multi-Cloud deployments with Kubernetes, VMs and technologies which consist of: Prometheus, microservices, Time-Series Databases, Application Performance Management (APM), Centralized Logging and logsearch solutions e.g., with Splunk clusters, Kafka, and Spark data streaming.

You will transform business requirements to component designs and code in a fast pace agile environment. In parallel, you will assist in the design of new systems and the redesign of existing systems to meet business requirements, changing needs, and integration of state-of-the-art technology. Also, you will ruthlessly prioritize and optimize designs where needed to ensure business needs are consistently being met. As a senior software engineer, you will have the opportunity to apply new technologies to overcome design challenges and technical problems enabling mission critical real-time telemetry systems.
