Jump Trading is an American proprietary trading firm founded in Chicago in 1999 that trades its own capital across futures, equities, options, fixed income and cryptocurrency using automated strategies. It is unusually secretive even by the standards of its industry, publishes almost nothing, and competes on latency, research quality and infrastructure it builds itself, including its own microwave and fibre network routes. Headquartered in Chicago with offices in London, Singapore, Shanghai and elsewhere, it employs researchers, quantitative developers and low-latency engineers, and it also operates the crypto arm Jump Crypto.

Jump Trading is committed to world class research. We empower exceptional talents in Mathematics, Physics, and Computer Science to seek scientific boundaries, push through them, and apply cutting edge research to global financial markets. Our culture is unique. Constant innovation requires fearlessness, creativity, intellectual honesty, and a relentless competitive streak. We believe in winning together and unlocking unique individual talent by incenting collaboration and mutual respect. At Jump, research outcomes drive more than superior risk adjusted returns. We design, develop, and deploy technologies that change our world, fund start-ups across industries, and partner with leading global research organizations and universities to solve problems.

We are looking for an adaptable hands-on individual, passionate about the details and nuances of managing Linux HPC environments at scale, and eager to tackle complex and unpredictable operational work as their primary job function.

What You'll Do:

  • Provide front-line operational support for 24/7 Linux HPC compute, storage, and interconnects. Technologies involved include RDMA fabrics, parallel filesystems, HPC batch schedulers, FUSE filesystems, internal Jump software, multi-vendor hardware, cybersecurity requirements, a challenging and unpredictable client workload, and high user expectations
  • Solve problem reports and questions posed by members of Jump's research community, escalating as needed and managing the entire problem lifecycle
  • Respond to alerts in a timely fashion
  • Participate in large, coordinated maintenance operations, including during evenings and weekends
  • Work on global projects across a wide range of infrastructure
  • Write code for diagnosing, resolving, and triaging difficult problems and automating frequently performed tasks
  • Collaborate with team members and across teams to write code and testing infrastructures spanning both new and existing codebases in multiple programming languages
  • Manage relationships with outside vendors, including traveling both domestically and internationally to meet with current and potential vendors
  • Implement and support performance monitoring and fault monitoring systems
  • Develop and improve systems and user documentation
  • Develop and monitor the tools used to maintain a production computing environment
  • Provide operational support as primary job function
  • Adhere to all company cybersecurity and IT policies, including performing all work using only approved hardware and software

  • Other tasks as assigned or needed
  • Work from company office an average of 5 days a week

Skills You'll Need:

  • A desire for operational work as primary job function
  • At least 2+ years of professional experience with Linux systems administration
  • High performance computing (HPC), including parallel filesystems (e.g., Lustre, GPFS), batch systems (e.g., Slurm, Grid Engine), and high-performance network interconnects experience is a plus, but not required
  • High proficiency with at least one programming/scripting language (e.g., Go, Python, C) and ability to learn additional languages quickly
  • A compulsion to perform root cause analysis
  • Strong verbal and written communication skills, including the ability to communicate effectively and efficiently with both coworkers and third-party vendors
  • Strong collaboration skills with a willingness to undertake tasks of various technologies and complexities
  • Ability to independently manage complex projects and multiple workstreams
  • Strong sense of urgency
  • Willingness to perform regular operational maintenance work during evenings and weekends and as needed
