This position offers the opportunity to be part of a collaborative and engaging working environment.

What you’ll do day-to-day

• Be part of a team that designs and maintains the firm’s global network, operating systems, security policy and infrastructure, and core network services across our datacenters, cloud services, and global offices.
• Work to continuously improve the security framework of a fast-paced, large-scale infrastructure environment that supports investment activity and technology development across the firm.

Who we’re looking for

At least ten years of comparable work experience and development experience in Python is required; a degree in computer science or another technical discipline is preferred.

Excellent troubleshooting capabilities and experience with diagnostic tracing tools at both the host and network level, along with in-depth knowledge of Linux-based operating systems and associated configuration management tools.

Impressive communication skills, with the ability to work effectively with colleagues across a global team and with different departments at the firm.

Familiarity with automated build, software deployment, and CI/CD systems.

Experience with Rust, Java, C, Go, and C# is preferred, as is experience maintaining infrastructure related to DNS, DHCP, and Kerberos.

Working knowledge of network protocols, information security concepts, databases, large-scale storage, and Windows/Linux interoperation is also preferred
