About the Client:

Our client is a leading global research, technology and trading firm where engineering is at the core of their success. Their infrastructure powers ultra-low latency, high-throughput, mission-critical systems at scale. The culture is built on the belief that everyone is both an individual contributor and a leader. In High Frequency Trading (HFT), hierarchy is flat, and every engineer is expected to be T-shaped: deep in one or two core domains, and broad across many others.

The Role:

As Technical SRE Lead, you will lead from the trenches.

You will not be a distant manager. You will architect, code, troubleshoot, debug, tune, and deploy.

You will be hands-on every day.

You will drive reliability, performance, and scalability across low-latency systems and critical trading infrastructure.

You will mentor, coach, and uplift engineers across the team by working side by side, pair debugging, reviewing, and teaching. You will own cross-functional projects end-to-end, from design through rollout and ongoing optimisation.

You will be on call within a global follow-the-sun rotation, contributing both operationally and strategically.

You will shape and evolve best practices, tooling, standards, and incident response strategies across the tech stack. This role requires you to work alongside your team, not above them.

What We Are Looking For:

Strong experience in SRE, DevOps, operations or infrastructure engineering in high-scale, high-performance environments.

Deep comfort with Linux internals, performance tuning, kernel behaviour, scheduling, I/O, and memory. Network expertise, including routing, VLAN, multicast, Ethernet, LLDP and more. Strong coding and scripting skills (Python, Bash or Shell, or similar). C++ or other systems languages are a plus.

Demonstrated ability to lead technically, having led projects and mentored teams, while also maintaining individual contributor excellence.

You embody the T-shaped engineer mentality: deeply rooted in your core domain, yet broad enough to engage across the entire stack.

Excellent problem-solving under pressure and debugging in real time. Ability to communicate clearly, influence across teams, and drive ownership.

What They Offer:

Massive upside, no glass ceilings.

Top-tier compensation for top-tier performance.

Full relocation and sponsorship support.

Exposure to global markets and cutting-edge infrastructure. Rich technical challenges in a domain where performance and reliability are everything. A culture that values autonomy, mastery, and impact. You will lead by example, not by mandate.

If you are a leader who rolls up your sleeves, thrives in technical complexity, and believes that leadership means doing, not just directing, we want to talk.
