We’re hiring for a Linux Engineer to join the Compute Engineering team at one of the most technically advanced hedge funds and market makers in the world. This is a rare opportunity to work on low-level Linux engineering that directly supports global trading and research systems.
This isn’t a typical Linux admin role. You won’t be managing users or installations — you’ll be writing the code that shapes the Linux OS itself, making kernel-level changes, tuning for ultra-low latency, and solving the kinds of problems that get escalated all the way to Red Hat.
What you’ll be doing:
- Writing and maintaining tools and infrastructure around the Linux OS
- Working closely with hardware and trading teams to fine-tune system performance
- Digging deep into memory, CPU, and I/O behavior to uncover and fix bottlenecks
- Automating the build, test, and release of custom Linux images
- Helping shape the future of Linux systems at scale in a highly technical, low-latency environment
What we’re looking for:
- 4+ years of deep Linux experience — ideally across RHEL, CentOS, or Ubuntu
- Strong coding skills in Python or Go (bonus points for C++ or Rust)
- Experience tuning system performance (kernel parameters, memory, scheduling, etc.)
- Knowledge of infrastructure-as-code tools (e.g. Ansible, Terraform, Packer) is a plus
- Someone who’s curious, hands-on, and thrives in an engineering-driven culture
Why this role stands out:
- You’ll work on genuinely challenging, interesting problems with real-world impact
- The team is highly respected — they submit the most bugs to Red Hat
- You’ll be surrounded by some of the best engineers in the industry
