DevOps Engineer - Linux Application Support & Automation (3-6 years exp)

Linux Platform Engineer – Linux Application Support & Automation

We are seeking a versatile DevOps Engineer with strong practical Linux knowledge focused on supporting and troubleshooting application workloads running on Linux servers. This role bridges Linux operational support with DevOps automation, emphasizing scripting, build support, and production monitoring rather than deep Linux system engineering or kernel-level administration.

Key Responsibilities:

• Monitor, troubleshoot, and support Linux-based production environments hosting critical software applications.
• Investigate system performance issues including memory usage, process behavior, and file distribution; identify root causes and coordinate with infrastructure/network teams for resolution.
• Maintain and support CI/CD pipelines (e.g., Jenkins jobs), automate build processes, and assist in deployment workflows.
• Develop and maintain automation scripts primarily in Python and Bash to improve operational efficiency, automate repetitive tasks, file distribution, system monitoring, and alerting.
• Collaborate closely with application development, infrastructure, security, and network teams to ensure smooth system operations and timely issue resolution.
• Manage Linux user-space tools and commands effectively to support application runtime without involvement in server provisioning or kernel configuration.
• Assist in configuring process/thread CPU affinity and optimizing resource usage based on application requirements.
• Participate in process orchestration and support tooling related to build systems and data jobs.

Required Qualifications:

• Strong practical knowledge of Linux operating systems with proficiency in Linux commands for troubleshooting (processes, memory, file systems).
• Experience with scripting languages, primarily Python; strong Bash scripting skills are highly desirable.
• Familiarity with CI/CD concepts and tools such as Jenkins, GitLab, Bitbucket; ability to configure and maintain build jobs and scripts within these systems.
• Basic understanding of containerized workloads and Kubernetes from a user perspective (running and supporting pods) without responsibility for cluster or infrastructure management.
• Ability to analyze application performance issues, understand process resource consumption, and implement user-space solutions.
• Good communication skills and willingness to collaborate across multiple teams.
• Proactive problem-solving attitude with a focus on automation to reduce manual intervention.

Preferred Skills:

• Exposure to Java, C++, or Rust codebases to assist in build troubleshooting (not development-focused).
• Experience with monitoring tools such as Prometheus, Grafana, or Zabbix is a plus.
• Knowledge of networking basics relevant to Linux application support (e.g., understanding of multicast or network card issues) without direct hardware management responsibilities.
• Understanding of security policies related to Linux environments (firewalls, SSH, CIS benchmarks) from a collaborative standpoint.

What This Role Is Not:

• This is not a Linux system administrator or kernel developer role. You will not be responsible for provisioning or configuring servers, managing kernel-level settings, or administering the entire Linux infrastructure.
• There is no responsibility for managing network switches, firewalls, or physical hardware. Those are handled by dedicated infrastructure and network teams.
• You will not operate as a cloud infrastructure engineer or perform cloud resource provisioning; the environment is on-premises with internally managed compute resources.

Why Join Us:

• Work in a dynamic, multi-disciplinary team supporting critical trading systems and applications on a powerful on-premises Linux environment.
• Opportunity to apply broad skills spanning Linux operations, DevOps automation, and scripting in a role that requires independence and collaboration.
• Contribute to automating workflows that directly impact production efficiency and reliability.
• Engage with diverse technologies and participate in high-impact problem solving without being siloed into narrow technical niches.

Experience Level:

• 3 to 6 years of relevant experience preferred. Candidates with strong skills and a growth mindset are encouraged regardless of exact years.

This role is ideal for candidates who are strong Linux users with scripting and DevOps automation capabilities, eager to support production systems and continuously enhance operational workflows without deep system engineering or infrastructure provisioning responsibilities.
