IT Administrator / IT Operations Manager

Role Overview

This role is for someone who thrives in fast-moving, high-accountability environments, with deep hands-on experience in IT administration, user onboarding, and secure system access across cloud and on-prem infrastructure. You will ensure that every device, user, and system across the firm is managed, monitored, and protected with industry-best practices.

You’ll work closely with engineering, HR, and leadership to deliver secure and frictionless technology operations — from Day 1 onboarding to day-to-day network and access management, including overseeing cloud IAM policies and end-user compute environments.

What You’ll Do

• Own

  employee onboarding/offboarding workflows

  : provision laptops, manage VPN access, secure credentials, and control tool permissions across the stack.
• Administer and govern

  cloud access and IAM

  across AWS, GCP, Azure — ensuring least-privilege access, auditability, and compliance.
• Deploy, maintain, and support

  DaaS solutions

  like Citrix, VMWare Horizon, or Azure Virtual Desktop.
• Manage

  firewalls, VPN servers, and endpoint protection

  (Sophos, Defender, etc.) across office and remote environments.
• Maintain asset inventory and manage

  hardware procurement, deployment, and troubleshooting

  for servers and end-user devices.
• Handle

  network and internet infrastructure

  — WiFi, leased lines, redundancy, firewall rules, and traffic monitoring.
• Monitor and respond to

  security incidents

  or IT service requests in a timely and documented manner.
• Manage firm-wide

  licenses, software installations

  , and tool configurations (Office365, Zoom, Slack, Jira, GitHub, etc.).
• Define and enforce

  IT policies and best practices

  around access control, patch management, device usage, and escalation protocols.
• Work with engineering and security leads to maintain audit logs, conduct reviews, and close gaps across IT surface area.

What We’re Looking For

• 10+ years of experience in IT systems administration, preferably in finance, trading, or security-conscious industries.
• Proven expertise in managing cloud IAM across AWS, GCP, and Azure.
• Hands-on experience with

  Citrix

  ,

  VMware

  , or

  Azure Virtual Desktop

  .
• Strong understanding of

  endpoint protection

  ,

  data loss prevention (DLP)

  , and

  SIEM tools

  .
• Familiarity with

  Active Directory

  ,

  Intune

  ,

  Windows and Linux servers

  , and

  mobile device management

  (MDM).
• Experience managing

  office infrastructure

  — switches, routers, firewalls (Fortinet/Sophos), VPNs, printers, and conferencing setups.
• Strong documentation habits and a proactive, security-first mindset.
• Excellent troubleshooting skills and ability to support both technical and non-technical teams.

Nice to Have

• Certifications like

  CompTIA Security+

  ,

  Microsoft Certified: Azure Administrator

  ,

  AWS Certified SysOps Administrator

  , or

  CCNA/CCNP

  .
• Prior experience setting up

  SIEM

  ,

  SSO

  architecture, or

  compliance frameworks

  (ISO 27001, SOC2, etc.).
• Experience supporting

  distributed teams

  or

  multiple office locations

  .
• Familiarity with automation tools (e.g., scripting with PowerShell, Bash, Python for IT ops).
