• Act as the senior escalation point for server-side issues, performing in-depth troubleshooting and root-cause analysis and driving permanent fixes.
• Drive automation across server provisioning, configuration, patching, and lifecycle management, reducing manual effort and improving consistency.
• Work closely with the network operations team on architectures spanning routing, firewalling, load balancing, and DDoS protection, and with the DevOps team on deployment pipelines, tooling, and platform integration.
• Engage directly with clients to gather technical and business requirements, then design and present tailored solutions, including multi-site, high-availability, and latency-sensitive trading environments.
• Prepare solution designs, architecture diagrams, bills of materials, and cost estimates for client proposals, and support the sales team through the pre-sales process.
• Partner with management to define, prototype, and launch new products and services, contributing technical direction, cost modelling, and pricing input.
• Evaluate new technologies, platforms, and vendors, and recommend improvements to our infrastructure and service portfolio.
• Establish and enforce standards for security, system hardening, monitoring, documentation, and change management.
• Mentor engineers across the team and promote knowledge-sharing and best practices.

Key Skills/Experience:

• Proficiency in automation and scripting (Bash, Python, Ansible; Terraform is a plus).
• Good understanding of networking fundamentals (TCP/IP, VLANs, routing, firewalls, load balancing, VPNs), enough to design solutions jointly with network engineers.
• Experience with monitoring and observability tools such as Zabbix, Prometheus, or Grafana.
• Strong knowledge of security best practices, system hardening, and compliance considerations.
• Demonstrated experience in solution design or pre-sales, including translating client requirements into technical proposals and cost estimates.
• Excellent communication skills in English, with the ability to present to clients and work effectively with management.
• Strong ownership, sound judgement, and the ability to lead projects independently.
