Linux is the foundation of PDT’s quantitative modeling and global trading systems. It comes as no surprise, then, that constantly improving our Linux platform is critical to our business, and we’re looking for exceptional Linux engineers to join the effort.

You’ll thrive in this role if you know Linux inside and out. This includes optimizing current infrastructure, automating where it makes sense, and tracking the latest kernel features and performance tool developments. Engineers here own the full lifecycle of their work, because tight feedback loops generate the best systems.  For someone with a get-things-done mindset—whether parsing details or drafting transformative blueprints—this position on our Systems team could be a great fit.

Why join us?  PDT Partners has a stellar 25+ year track record and a reputation for excellence.  Our goal is to be the best quantitative investment manager in the world—measured by the quality of our products, not their size.  PDT’s very high employee-retention rate speaks for itself.  Our people are smart, and our community is close-knit, down-to-earth, and diverse.

Responsibilities:

  • Improve the performance of our trade execution plant, including support of high performance, low latency systems, hardware evaluation, kernel internals, and kernel-bypass, which impacts firm success
  • Lead and participate in many transformative projects, such as improved observability, cloud migration of core services and workloads, next generation colo hardware, and architecting and supporting multi-region resilient trading systems
  • Work with many teams to identify and solve tricky cross-team problems
  • Operate in many different domains and learn new things, including large scale enterprise storage, cloud, infosec, and others
  • Develop software to improve our systems
  • Support our production Linux environment, including system provisioning, monitoring, packaging, and configuration management.
  • Enhance our current environment, especially by proposing and implementing automated tools
  • Identify and resolve issues before they cause trouble, while handling disruptions and escalated incidents with a sense of urgency
  • Participate in an on-call rotation

Below, you'll find a list of skills and experiences we think are relevant. Even if you don’t think you’re a perfect match, we still encourage you to apply because we are committed to developing our people.

  • 3+ years of relevant experience, particularly in finance, tech, or any other field that depends on fast, reliable, real-time systems.
  • Deep knowledge of Linux, covering package management, kernel and subsystems, config management, and virtualization, among other things.
  • Demonstrated coding ability beyond simple scripting.
  • Experience with full stack debugging and performance analysis, with tools like tcpdump, gdb, perf, strace, ss, and ethtool.
  • SME-level experience supporting higher level systems such as Kerberos, LDAP, NetApp, Splunk, DNS, PostgreSQL.

Education:

  • Bachelor’s degree in computer science, engineering, or a related field

Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past.
