• Collaborating with a global Linux Engineering team for coordinating work, engineering projects, changes, and on-call schedules
• Serving as a liaison between the Linux Engineering team and various trading desks and teams
• Configuring, deploying and maintaining DRW’s Linux environments in a declarative and repeatable manner
• Actively monitoring the health of our entire Linux server environment; performing day to day troubleshooting
• Application packaging and maintenance of software repositories
• Evaluating and recommending new hardware and software technologies or solutions

You will bean ideal member of the team if you have:

• Experience working with configuration management tools, ideally Ansible, Chef, or Puppet
• Scripting and automation experience with one or more of the following: Bash, Python, or another high-level programming language
• Extensive Linux support and engineering experience in a large (10,000+ server) high availability environment
• Strong knowledge of Red Hat-based and Debian-based platforms (CentOS, Rocky, Alma, Oracle, Ubuntu)
• Solid understanding of protocols such as Kerberos, DNS, and DHCP, and applications like Kubernetes, VMware, and Openstack.
• Previous experience tuning and debugging Linux systems for high performance, low latency trading applications
• A firm understanding of IP networking, routing, and multicast traffic

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in DRW ’s Equal Employment Opportunity policy,we do not discriminate on the basis of any protected group status under any applicable law.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
