[HIRING] Senior Security Platform Engineer (Detection Engineer) — Hemel Hempstead / Slough / London, UK
NTT Global Data Centers is looking for a Senior Security Platform Engineer to join their global Office of Information Security team. This is a hands-on detection engineering role with real ownership — you would be a senior member of a 24/7 cybersecurity team responsible for threat hunting, SIEM/SOAR platform management, incident response, and vulnerability analysis across NTT's global data centre infrastructure.
This is not a pure SOC analyst seat. You would lead the administration and optimisation of enterprise security platforms, direct complex incident response across multiple vectors (endpoint, EDR, malware analysis, network and computer forensics), design and execute advanced vulnerability assessments, and drive automation initiatives to streamline detection and response workflows. You would also mentor junior engineers and lead strategic security projects.
What makes this role distinctive:
NTT GDC operates critical infrastructure across multiple countries. The successful candidate will have the opportunity to expand into OT/ICS security as the function matures — NTT will provide structured training and development in OT security, so you do not need to bring that experience on day one. Candidates who do have ICS/SCADA exposure will be given preference, but it is not a gate to candidacy. If you are a strong IT detection engineer who wants to develop into critical infrastructure security, this is a rare opportunity to do that with structured support rather than being thrown in at the deep end.
What they are looking for:
— 5–10 years of experience in IT and/or Security Operations Centres
— Advanced expertise in SIEM/SOAR platform architecture, implementation, and optimisation
— Proven experience leading security incident response end to end — containment, root cause analysis, post-incident review
— Strong threat hunting capability — data correlation across network traffic, email logs, malware samples, DNS records, web server logs
— Advanced vulnerability assessment experience using both automated and manual techniques
— Solid networking, Windows, Linux, and security architecture foundations
— Experience configuring and managing security controls: RBAC, IAM, Zero Trust, UTM, Proxy, SOAR
— Familiarity with log collection mechanisms (Syslog, log file, DB API)
Preferred certifications: CySA+, PenTest+, CCSP, GCIH, OSCP, CISM, CISSP. IT certs like CCNA, CCNP, RHCSA, AZ-500, SC-200 are also valued. OT/ICS certs (GRID, GICSP) are a bonus.
Compensation: £75,000–£95,000 per annum
Location: Hybrid — Hemel Hempstead (preferred), Slough, or London, minimum 2 days per week in office. Up to 25% domestic/international travel.
Package includes: Pension, private medical insurance, training and certification budget (NTT funds SANS courses, CISSP/OSCP prep, and OT security training), annual bonus, travel allowance.
This role has been mapped against the NIST NICE Workforce Framework v2.1.0 for standardised competency alignment. Primary work roles: Defensive Cybersecurity (PD-WRL-001), Infrastructure Support (PD-WRL-004), Incident Response (PD-WRL-003), and Vulnerability Analysis (PD-WRL-007).
