• Proven leadership in engineering, architecture, technical direction, mentoring
• Solid grasp of OS internals, CPU architecture, and systems-level performance
• Experience building fault-tolerant, throughput-heavy applications
• Strong communication skills, able to align across trading, research, and infra

Nice to Have

• Background in low-latency or high-frequency systems
• Python for scripting, research pipelines, or glue code
• Experience with networking (TCP, UDP, L1/L2 stack)
• Familiarity with x86 assembly, memory barriers, and CPU profiling
• Participation in CTFs or algorithmic programming contests (IOI, ICPC, Hashcode)

What’s on Offer

• Senior technical ownership in a lean, high-impact trading team
• Up to £220,000 base salary + bonus
• Health insurance, sports reimbursement, tuition and training budget
• Flat team structure with direct access to CTO and trading leads
