Job description

• Engineer, automate, and operate the firm's Linux fleet across private data centers and cloud regions, holding it to the reliability, performance, and security standards demanded by a quantitative trading environment


• Perform kernel-level and system-level performance tuning on latency-sensitive systems, including core pinning and shielding, kernel bypass, network stack tuning, and interrupt steering


• Build and maintain deployment, configuration, patching, and monitoring automation in Python and modern configuration management, treating the Linux estate as code rather than as hand-managed servers


• Own significant pieces of the Linux platform surface hands-on across both Red Hat Enterprise Linux and Ubuntu, from provisioning through in-life management


• Define and enforce Linux security baselines and hardening standards, partnering with Security Engineering on patching cadence, privileged access, and the firm's broader identity and short-lived-credential strategy


• Contribute to the OS-platform technical strategy set by the Tech Lead, Linux Platform Engineering, bringing deep Linux expertise so that decisions span both platforms coherently


• Partner with Data Center & Fleet Infrastructure on provisioning and asset management, and with Developer Tools & Infrastructure on build and CI integration, so the Linux platform is well-integrated with the rest of the stack


• Provide production support for the Linux surface, including participation in an on-call rotation, and drive continuous improvement of its reliability and observability


• Mentor engineers across the team on Linux internals, performance, and automation, raising the bar for how the firm builds and operates Linux infrastructure

Qualifications

• Bachelor's degree in computer science, a related technical field, or equivalent practical experience


• 5+ years of experience in systems or platform engineering, with a focus on Linux infrastructure


• Advanced experience with the inner workings of the Linux kernel, including core pinning and shielding, kernel bypass, network stack tuning, and interrupt steering


• Strong working knowledge of both Red Hat Enterprise Linux and Ubuntu


• Strong experience automating deployment, configuration, patching, and monitoring with Python, including modern configuration-management approaches (e.g., Ansible, or equivalent)


• Experience defining and applying Linux security baselines and hardening standards (e.g., CIS Benchmarks, STIGs)


• Experience with distributed systems and cloud platforms

Preferred Qualifications

• Master's degree or PhD in Engineering, Computer Science, or a related technical field


• Experience in one or more general-purpose programming languages (e.g., C++, Java, Rust)


• Experience with \"metal as a service\" type build factories and Kubernetes-based bare-metal provisioning systems


• Experience tuning Linux for low-latency or trading-adjacent workloads


• Strong working knowledge of agentic developer productivity tooling and customization, such as spec-driven development, MCP servers, and Claude Code sub-agents, skills, and workflows


• 3+ years of experience working in a complex, matrixed organization involving cross-functional or cross-business projects


• Experience partnering with quantitative developers and researchers in a finance setting


• Contributions to relevant open-source projects


• Excellent written and verbal communication skills


• High level of intellectual curiosity, strong work ethic, and a keen attention to detail
