Cyber Security Engineer

Role Overview

FNZ is building a global Cyber Platform Engineering function responsible for the operation, reliability, and evolution of the firm's core security platforms.

We are seeking a Cyber Security Platform Engineer to join the growing engineering capability in India. This is a hands-on technical role focused on operating and improving FNZ's production cyber security platforms.

The successful candidate will help ensure FNZ's security platforms remain reliable, well-configured, and continuously improving through engineering, automation, and operational excellence.

This role sits within Cyber Platform Engineering, not the Security Operations Centre (SOC). The focus is on engineering and operating security platforms, rather than monitoring alerts or performing SOC analysis.

You will work closely with global engineering teams across the UK, US, and APAC.

Core Responsibilities

Operate, maintain, and continuously improve FNZ's production security platforms to ensure reliability, performance, and operational effectiveness.

The role combines hands-on platform operationwithengineering improvements that enhance platform capability and reduce operational overhead.

Responsibilities include:

• Configuring, operating, and optimising enterprise security platforms
• Supporting platform upgrades, patching, and lifecycle management
• Monitoring platform health, reliability, and performance
• Troubleshooting operational issues across security platforms
• Ensuring platforms operate in line with FNZ's global security and operational standards
• Assisting with automation of platform configuration and operational workflows
• Supporting integrations between security platforms and internal systems
• Writing scripts or tooling to improve operational efficiency
• Supporting infrastructure automation or configuration improvements
• Helping improve telemetry pipelines and data flows between security platforms

Engineers are expected to approach platform operations with an engineering mindset, identifying opportunities to improve automation, reliability, and operational efficiency over time

Incident Engineering Support

Provide engineering support during security incidents where platform expertise is required.

This includes:

• Supporting incident response teams with platform troubleshooting
• Assisting with root-cause analysis
• Helping implement fixes and improvements following incidents

The focus is platform engineering support, not incident monitoring or SOC investigation.

Platform Reliability & Continuous Improvement

Work with the wider engineering team to improve the maturity and reliability of FNZ's security platform environment.

This includes:

• Identifying recurring operational issues
• Contributing to automation initiatives
• Improving platform observability and operational metrics
• Supporting adoption of new security tools and platform capabilities

Working Pattern

The team provides global coverage across shifts aligned with international operations.

Core hours will align with APAC and EMEA collaboration, with occasional out-of-hours work required during major incidents or platform maintenance windows.

Required Experience

Candidates should demonstrate hands-on experience operating enterprise security platforms.

Typical background includes:

• 3–9 years in cyber security engineering or platform engineering roles
• Hands-on experience working with enterprise security platforms
• Experience troubleshooting operational issues across security controls
• Experience working within distributed global engineering teams

Technical Experience

Experience across several of the following security platform domains is expected:

• Endpoint security platforms (EDR / XDR) such as CrowdStrike, Defender, SentinelOne
• Secure Web Gateway / Proxy platforms such as Netskope, Zscaler, iBoss, Prisma Access
• Web Application Firewalls (WAF) and application-layer protection platforms
• Security logging and SIEM platforms
• Email security platforms and secure email gateways
• Vulnerability management platforms
• Network security controls, including next-generation firewalls

Candidates should demonstrate experience operating, configuring, and supporting these platforms in production environments.

Engineering & Automation Experience

Experience in the following areas is beneficial:

• scripting or automation (Python, PowerShell, Bash or similar)
• working with APIs for platform integrations
• infrastructure automation or configuration management
• operating security tooling in cloud environments

Nice to Have

Experience in the following areas would be beneficial:

• infrastructure-as-code or DevOps practices
• cloud security platform engineering
• integrating security tooling within CI/CD pipelines
• platform telemetry and observability tooling

What Success Looks Like

The successful candidate will:

• support the reliable operation of FNZ's security platforms
• contribute to engineering improvements and automation initiatives
• help maintain platform performance and stability
• collaborate effectively with global engineering teams
• grow technical expertise across FNZ's security platform ecosystem

Why This Role Matters

Security platforms form a critical part of FNZ's global technology infrastructure.

The Cyber Platform Engineering team ensures these platforms remain:

• reliable
• scalable
• well-engineered
• continuously improving

This role contributes directly to maintaining the security and resilience of FNZ's global environment.
