As a member of our Platform Development team, you will be instrumental in building and optimizing high-performance trading systems, research compute clusters, databases, support systems, and more. You will heavily utilize Linux and Windows internals while working on servers in our HPC environment. 

What You'll Do:

Automate and Evolve: Contribute to our library of home-grown tools, written primarily in Python and Bash, to automate monitoring, and maintenance, allowing you to focus on performance related issues and projects.

Collaborate: Work closely with Strategy Developers, Quantitative Researchers, and trade-supporting application teams to translate complex problems into scalable solutions.  Coordinate with IT infrastructure teams, including storage and networking, to identify and implement the best solutions.

Optimize: Tune operating systems and batch workflows for performance. Dive deep on root-cause analysis of systems issues.  Integrate all of these solutions into our systems effectively and efficiently.

Comprehensive HPC Environment Management: Oversee all aspects of our HPC environment, including the scheduler, parallel filesystems, GPUs, and interconnects.

High throughput storage: Implement and optimize high-performance storage solutions, including Lustre, VAST, and GPFS, to efficiently support and enhance cluster performance.

Capacity Planning and Design: Develop strategies to ensure optimal resource allocation and scalability, using analytics to forecast needs and design efficient, reliable systems.

Troubleshooting and Tuning: Utilize monitoring and diagnostic tools to quickly pinpoint failures, streamline troubleshooting processes, and ensure the timely recovery of disrupted workflows.

• A Bachelor’s degree in Engineering, Computer Science, Information Systems, or a related discipline.
• 5-7 years of progressive experience building Linux and/or Windows based HPC based platforms.  
• Familiarity with kernel-level and I/O subsystem tweaks and tools such as sysctl, strace, tcpdump, and netstat. Bonus points for equivalent Windows knowledge (registry, procmon, wireshark, tshark).
• Recent hands-on experience with automation in Python or other tools.
• Experience administering Lustre, GPFS, VAST, or other parallel filesystems.
• Understanding of resource schedulers like HTCondor, SLURM, or similar.
