• Implementing observability and telemetry solutions for performance and reliability
• Partnering with network, platform and security teams to deliver resilient, scalable systems
• Contributing to incident response and production reliability
• On‑call responsibilities for the most critical parts of the infrastructure

Qualifications

We’re looking for a skilled network engineer with technical experience of managing high‑performance, low‑latency, scalable and resilient network infrastructure solutions. The ideal candidate will have the following skills and experience:

• Confident with Python and solid engineering fundamentals across testing, version control and CI/CD
• Experience with infrastructure‑as‑code and automation tools such as Ansible, Terraform and Jinja2; also must have experience leveraging AI tools, such as Claude Code
• Familiarity with Docker and Kubernetes
• Exposure to monitoring, observability or telemetry in distributed systems
• Pragmatic problem solver who can operate in ambiguity and take ownership
• Comfortable working in collaborative, fast‑paced engineering teams
• Deep understanding of networking fundamentals and ideally experience in network engineering in financial markets

Benefits

• Highly competitive compensation plus annual discretionary bonus
• Lunch provided (via Just Eat for Business) and dedicated barista bar
