Senior Software Engineer - Unstructured Data Storage

DELL EMC Isilon is the leader in scale-out storage systems. Our clustered storage and data management solutions drive unique business and economic value for customers by maximizing the performance of their mission-critical applications, workflows, and processes.  Isilon enables enterprises and research organizations worldwide to manage massive and rapidly growing amounts of file-based data in a highly-scalable, easy-to-manage, and cost-effective way.  We’re in the business of transforming the way data is stored.  At the forefront of the big data movement, our highly parallelized, distributed architecture has completely redefined the storage model

What is Protocols Engineering?

Our teams build the network interfaces our customers use to reach their data.   We are delivering future capabilities for new workloads such as Hadoop as well as scaling existing NAS workloads to massive levels and with non-disruptive operations to keep businesses running 24x7x365.  Our identity management technologies ensure that we can work in almost any environment and provide our customers with seamless integration to both directory services and storage protocols.

How do we do our work?

We create a pipeline of work based on input from our customers, internal engineering needs, our product managers, and our strategic bets.  Our organization is “multi-threaded” in how we manage our engineering capacity and the throughput at which we deliver.   We aim to run a

lean organization to build the right things the right way at the right time.

What technologies do we use and build?

We strive to use the best tool for the job at hand.   We build our core infrastructure and network code in a combination of C and C++ with control functions leveraging the flexibility and rapid development provided by Python.  We use git as our source control system and leverage GitHub Enterprise based workflows for building and testing our code in a continuous integration model.  Creating internal clusters for testing and development is smooth and easy using our automated builds and virtual deployments.
