? Sector: Financial Services

You'll be joining the infrastructure team at a major global financial services firm, working hands-on across their full technology stack. The scope is broad — PoC and RFP/RFE initiatives, day-to-day operations, and support of live IoT systems including building management, lighting controls, occupancy monitoring, and air quality.

This isn't a narrow specialism role. You'll move between networking, server administration, automation scripting, and IoT/OT device support depending on what the day demands.

Requirements

• Leading and supporting infrastructure PoC, RFP, and RFE initiatives across diverse platforms

• Managing and troubleshooting network and security configurations — routers, switches, proxies, firewalls, DMZ, RBAC, Kerberos, SSO, LDAP, AD

• Server administration across Windows, Linux, Mac, and vendor ecosystems (CA, BMC, IBM DataPower)

• Writing and maintaining automation scripts in PowerShell, Python, Perl, or Shell

• Supporting, troubleshooting, and upgrading IoT/OT devices across Android, Windows, Linux, Unix, iOS

• Working with SecDesign teams to apply appropriate controls for integrated solutions

• Ensuring production systems stay compliant within the Hygiene programme

• Strong network and security background — you understand layers, configs, and authentication flows inside out

• Server administration across multiple OS and vendor ecosystems — platform-agnostic is the expectation

• Real scripting ability in PowerShell, Python, Perl, or Shell — production experience, not surface-level

• Experience supporting IoT/OT devices in enterprise environments

• Clear, confident communication and stakeholder management skills

• CI/CD pipeline and cloud technology exposure

• BFSI or Capital Markets domain background

• CCNA, AWS, or Azure certifications

• Experience working in globally distributed teams
