Are you the kind of engineer who lives and breathes Linux looking for an opportunity where you can make a lasting impact?

We’re seeking a Linux System Administrator on behalf of a technology-driven trading firm with global reach and a reputation for high-performance systems, engineering craftsmanship, and operational excellence. You will join a collaborative, high-impact infrastructure team working directly alongside top-tier software engineers and traders.

This is a hands-on technical role where you’ll be responsible for maintaining, optimizing, and evolving a Linux-based trading environment that demands reliability, consistency, and speed. You’ll be empowered to bring creative ideas to the table, from automation to observability, and turn them into robust solutions.

What You'll Do

• Maintain and enhance a complex Linux-based infrastructure that powers real-time trading systems.
• Own the lifecycle of infrastructure components: provisioning, configuration, performance tuning, and decommissioning.
• Act as the first responder for hardware/software incidents, working closely with traders and developers to troubleshoot and resolve issues.
• Automate infrastructure management and operational tasks using Ansible, Shell, and Python.
• Manage and maintain data center hardware and on-prem server installations.
• Perform proactive audits of the environment to enforce security and compliance best practices.
• Monitor system performance and capacity to ensure stability and uptime for time-critical applications.
• Ensure consistent daily startup conditions for live trading systems across multiple environments and geographies.
• Standardize documentation, processes, and recovery procedures for internal teams.

The Company:

• Performance is the benchmark – You’ll work on systems where nanoseconds matter and optimization never stops.
• Your work moves markets – Infra here isn’t support. It’s central to trading new strategies, regions, and products.
• Engineers lead the way– No bureaucracy. If it’s the right technical decision, it goes live.
• Small team, full ownership – You build it, tune it, deploy it, and run it. No silos.

Who You Are:

• Solid experience with Linux system administration in performance-sensitive environments.
• Proficient in configuration and troubleshooting of servers and storage infrastructure.
• Skilled in Ansible or other configuration management tools.
• Familiarity with Python, Shell scripting, and command-line tooling.
• Strong understanding of IT security practices and system hardening.
• Experience managing hardware deployments and on-prem infrastructure in data centers.
• Bachelor’s degree in Computer Science, Engineering, Information Technology, or a related field.
• Excellent communication skills, especially when working across technical and non-technical teams.
• Experience with cloud platforms (AWS, Azure) is a plus.
• Bonus: Experience with Windows systems or hybrid environments.

• Performance-based variable compensation with excellent growth trajectory.

• Full relocation support, including budget, flights, house-finding assistance, and expat onboarding. • Daily fresh meals (breakfast, lunch, and dinner) from our in-house chef.

• Regular social events, Friday drinks, and a collaborative team culture.

• Travel reimbursement to and from the office.
