IT Infrastructure and Security Manager

Position Overview

We are a regulated financial institution operating a 5-day, 24-hour global trading platform. We are seeking a highly resilient, technical, and versatile IT Infrastructure and Security Manager to oversee our Mission-Critical infrastructure and cybersecurity domain.

This is NOT a purely administrative desk job. We need a hands-on leader and a troubleshooting expert (a "generalist" with deep technical roots) who can guide junior engineers, act swiftly during high-pressure production incidents, and collaborate directly with our Head of IT on strategic infrastructure design, cloud architecture, and technical problem-solving.

Key Responsibilities

• 24/7 Global Trading Infrastructure: Maintain and optimize high-availability infrastructure supporting global trading sessions (spanning HK, SG, US, and EU). Ensure zero downtime across internal networks and external market connections.

• Hybrid & Multi-Cloud Management: Oversee and architecture our multi-cloud ecosystem (AWS & Huawei Cloud) combined with our on-premises private Data Centers.

• Regional Network & Third-Party Connectivity: Manage robust regional networks connecting Hong Kong, Singapore, and US offices. Oversee critical connections with third-party vendors, liquidity providers, and financial counterparties.

• Hands-on Incident Management: Act as the first line of escalation and a technical anchor during critical system or security incidents. Lead the team to diagnose, hot-fix, and resolve complex issues immediately.

• Team Leadership & Mentorship: Guide, train, and level-up a team of junior/mid-level infrastructure and security engineers. Translate high-level blueprints into execution plans for the team.

• IT Architecture & Strategy: Work back-to-back with the Head of IT to design, review, and implement future-ready IT infrastructure, automation pipelines, and robust cybersecurity frameworks.

• Financial Compliance: Align infrastructure and security controls with financial regulatory requirements (e.g., HKMA, SFC guidelines) and maintain rigorous Business Continuity Plans (BCP/DR).

Requirements & Qualifications

• Experience: Minimum 8 years in IT infrastructure and security, with at least 3 years in a team-lead or managerial role, preferably within a Financial Institution, Brokerage, or Fintech firm.

• Trading System Exposure: Prior experience or strong technical familiarity with electronic trading systems, market data feeds, or low-latency financial environments is highly preferred.

• Technical "All-Rounder" Skills:

  • Cloud: Solid experience managing production environments in both AWS and Huawei Cloud.

  • Networking: Deep knowledge of corporate and data center networking, firewalls, routing, and cross-border connectivity (VPN, Leased Lines, SD-WAN).

  • Security: Practical knowledge of security hardening, vulnerability scanning, EDR, SIEM, and identity management.

• Mindset & Working Style:

  • Extreme ownership, analytical problem-solving skills, and the ability to stay calm and resourceful under intense pressure during system outages.

  • A "lead-by-example" management style—willing to deep-dive into logs and configurations alongside the team when needed.

• Language: Fluent in English and Chinese (Cantonese and Mandarin).
