Head of Infrastructure

About the Company and Role

We are hiring for a US-based systematic quantitative trading firm operating a global, exchange-connected production infrastructure.

The environment is largely on-premise, with physical presence in major colocation facilities including CME Aurora, Equinix (US and EU), and ICE environments. Market data volumes exceed 1 TB per day and continue to grow. Hardware layout, routing strategy, and exchange connectivity directly affect trading performance.

We are looking for a Head of Infrastructure who will take full ownership of this distributed setup, review the current architecture, align capacity with trading growth, introduce cost transparency, and bring a clearer structure to how the team operates.

This role requires proven experience operating exchange-connected infrastructure across colocation environments, bare metal systems, and production networks, with clear ownership of cost and capacity decisions.

Location: Austin, TX (USA) / London, UK / Munich, Germany (full-time, office-based).

We are offering:

• Highly competitive compensation package structured to reflect the scope of responsibility and long-term business impact;
• A senior leadership role with direct exposure to trading and technology decision-making;
• Real authority to shape architectural direction, cost discipline, and operational standards;
• Health, vision, and dental insurance;
• Flexible sick time policy.

What kind of qualifications we are looking for:

• Experience operating production infrastructure in electronic trading or other exchange-connected environments;
• Strong understanding of networking in office and datacenter contexts, including DNS, TCP/IP, NAT, VPN, and routing fundamentals;
• Practical experience working with hardware, including assessment of server and network equipment needs and component-level replacement such as NICs, memory, drives, and system boards;
• Comfort working in colocation environments with physical rack presence;
• Administration experience across Linux, Windows, and macOS, with an architectural understanding of higher-level services such as distributed storage;
• Experience writing automation scripts in Bash, Perl, or Python and deploying them via scheduling or orchestration tools;
• Solid engineering fundamentals, including clean coding practices and familiarity with OOP concepts;
• Experience deploying and maintaining database systems in production;
• Previous experience leading infrastructure or datacenter teams, ideally with exposure to budget and capacity planning.

Responsibilities:

• Review the current setup across datacenters and exchange connectivity, and identify structural gaps;
• Define and execute a modernization roadmap with clear priorities;
• Introduce measurable KPIs around reliability, cost efficiency, and capacity utilization;
• Clarify ownership within the team and adjust responsibilities where needed;
• Oversee hardware lifecycle planning, vendor coordination, and physical infrastructure strategy;
• Strengthen monitoring standards and incident response processes;
• Ensure the platform can scale in line with trading volume and strategy evolution.

If you have built and operated exchange-connected environments where latency, reliability, and cost discipline matter, and you are ready to take responsibility for a global setup that directly supports live trading, we would like to speak with you.
