OverviewHave you ever imagined the world with an infinite amount of storage available and accessible to everyone? A place where everyone in the world can easily access their books/music/photos/video/any data from anywhere at any time via any means (e.g., mobile phones, tablets, personal computers (PCs), smart devices, etc.). Did you ever desire a universally accessible storage system to record all the knowledge known to mankind, to keep all the books/music/videos ever created, or to store all the data collected from all the scientists in the world for them to collaborate upon? Do you want to be part of a team that strives to bring these to reality? If so, the Microsoft Azure Storage team is what you are looking for. We are building Microsoft’s cloud storage solution—Microsoft Azure Storage—which is a massively scalable, highly distributed, ubiquitously accessible storage system, designed to scale out and serve the entire world. We continue to have tremendous hockey stick growth, we have many exabytes of data stored, and are designing and building systems for zettabyte scale to support demand growth for the coming years.We are looking for a Senior Software Engineer who is interested in distributed storage, ensuring high availability and consistent performance. Candidates who enjoy learning complex interactions between components and identifying underlying causes of degradation will have the opportunity to learn from domain experts and analyze patterns at global scale. We debug issues at the highest and lowest levels, from comparing statistical data across regions or time, down to source code or assembly analysis.The Azure Managed Disk team are responsible for disks beneath Azure Virtual Machines, managing hundreds of thousands of servers which in turn are a fundamental building block for delivering a vast range of cloud services. To be successful, we must strive to be efficient in terms of resource dimensions including central processing unit (CPU), memory, input/output operations per second (IOPS), capacity, etc., and are constantly looking for how to best arrange and distribute usage while ensuring minimal disruption. We interact with physical hardware and implement logic to detect and recover from hardware faults, allowing cloud services to operate continually on imperfect systems. This is a continually evolving space where new approaches are explored and evaluated, where we are constantly challenged by an exponentially growing fleet, and your analysis can set the direction for the next decades.You will identify opportunities to monitor key aspects of system behavior, aggregate and observe metrics, build complex queries to draw connections between different systems, work with engineers on challenging problems and propose cross-team solutions, support teams in difficult debugging, and act as the final tier in customer support. To be successful in these areas, you must thrive while solving issues related to durability, availability, and concurrency for a distributed system. You will have an opportunity to make high-impact changes on a daily basis as you build a hyperscale storage system that may indirectly or directly be used daily by your friends and family.Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees, we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.ResponsibilitiesLeads investigation and analysis of complex distributed systems, tracing causation of faults.Leads identification of bottlenecks or load concentration, acting independently to mitigate issues while also defining automated algorithms to distribute load more effectively.Works across teams and organizations to establish algorithms and heuristics that are robust to degraded hardware or other recurring events.Determine and communicate patterns that represent areas for systemic improvement or provide efficient identification of known issues.Communicate with internal and external customers regarding opportunities to leverage Storage technologies in ways best suited to their needs.Holds accountability as a Designated Responsible Individual (DRI), mentoring engineers across products/solutions, working on-call to monitor system/product/service for degradation, downtime, or interruptions.Proactively seeks new knowledge and adapts to new trends, technical solutions, and patterns that will improve the availability, reliability, efficiency, observability, and performance of products while also driving consistency in monitoring and operations at scale and shares knowledge with other engineers.Qualifications Required Qualifications:Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
