  • Overview

    DDN Senior Performance Engineer


    The economic and engineering foundations of today’s datacenters are being radically transformed. Massive increases in ever-changing data are being generated and stored all over the globe, and need to be accessed, processed, analyzed, transformed and made available securely and in real time. At DDN we recognize and embrace this new age of massive and diverse data and we pioneer the technologies, architectures and highly innovative solutions that make data available instantly and effortlessly, to everyone, everywhere, all of the time.


    We are looking for a new Senior Performance Engineer to work within DDN’s Global Performance Engineering Team and operate DDN’s benchmarking centre in Dusseldorf. The Dusseldorf Office and Benchmarking Centre hosts a range of the latest DDN kit with servers, switches (IB and ethernet) and storage systems based upon DDN’s IME and SFA products. Benchmarks are run with GPFS, Lustre and other filesystems. Performance and Functional analysis are performed here by DDN performance engineering staff and by field engineers to fulfil both strategic goals and to support customer requests.


    The candidate will be able to map end goals around system characterisation and analysis to a systematic benchmarking methodology and see that exercise through from start to finish, usually ending with a customer or internal facing report. The candidate will be flexible in their work, able to setup systems and networks ready for remote benchmarking and also able to execute benchmarks on Lustre/GPFS/IME etc independently. Working within a global performance team and regularly communicating with field teams the candidate will be able to work both independently and in tight concert with others. The workload will be primarily concerning setting up and executing synthetic and application benchmarks, with a significant aspect of lab management.
