• Act as an infrastructure SME across Linux and networking layers
• Drive performance optimisation and automation across the stack
• Collaborate closely with engineering teams on architecture and delivery

• Support production systems and continuously reduce manual overheads

• Low‑latency, trading, market‑making, financial services or front‑office experience
