Principal Engineer - Cybersecurity Science & Analytics

Engineer and defend the digital backbone of one of the world’s largest global banks with real hands-on impact and zero management overhead

HSBC Technology builds and runs digital services that help millions of customers bank quickly, simply and securely - on one of the largest and most complex technology estates in the industry. Cybersecurity is investing in a step-change in engineering capability, and this role is central to making that real.

Cybersecurity Science & Analytics (CSA) is a team of cybersecurity scientists, data and analytics professionals and engineers. Our mission is to harness data, analytics, AI/ML and cybersecurity science to innovate and advance HSBC’s cybersecurity capabilities. We’re looking for a Principal Engineer reporting directly to the Global Head of Cybersecurity Science & Analytics, to set engineering direction across CSA and help solve our most complex technical challenges at pace and at scale.

You’ll leverage a multi‑petabyte data platform to reduce enterprise-wide security risk, automate real-time advanced detections and protect critical financial applications used by millions worldwide.

What you’ll do (hands-on, end-to-end)

You’ll be the most senior hands-on engineer in CSA, working across delivery teams to deliver the data platform, infrastructure and advanced analytics engineering that power Cybersecurity outcomes. Your work will influence ~150 technical staff in CSA and the wider global Cybersecurity function (~2,500) .

Core responsibilities

Software Engineering Leadership

• Build custom security applications, APIs and data-driven services aligned to Cybersecurity mission outcomes
• Lead end-to-end SDLC : requirements (functional & non-functional), development, technical testing, release and production support
• Set and actively enforce engineering standards (code quality, reliability, secure-by-design) as a sustainable competitive advantage
• Mentor and upskill engineers; raise the bar for engineering excellence across teams
• Drive major procedural and technological change in a complex global organisation connecting the dots across domains

Data Engineering at Scale

• Ingest, curate, centralise and optimise massive datasets (100TBs/day ) for high-value cyber use cases
• Build and optimise reusable data assets and pipelines for large-scale cybersecurity analytics
• Productionise and optimise pipelines with a focus on cloud cost optimisation and data asset curation
• Use Databricks / Spark and advanced analytics to deliver actionable insights Cloud-Native Analytics & AI/ML Enablement
• Design, deliver and maintain cloud-native ML/analytics pipelines in Azure for real-time detection and response
• Design pipelines to automate deployment of production models and automations to counter emerging threats
• Prototype, validate and scale new analytic techniques - turning research into production capability Cybersecurity Science & Rapid Response
• Conduct cybersecurity industry research and rapidly develop data-driven prototypes for live operational problems
• Support mitigation of advanced criminal and nation-state adversarial techniques
• Jump in on urgent vulnerabilities or emerging threats - making a difference when it matters most
• Work across cyber domains: network, endpoint, cloud security, cryptography, malware analysis, vulnerability assessment, PAM, anomaly/intrusion detection, incident response, offensive security
• Leverage key cyber data sources: EDR, firewall logs, proxy logs, vulnerability reports

Cross-Organisational Influence

• Partner with threat hunters, threat intelligence, vulnerability management and more to translate complex requirements into scalable solutions
• Lead architecture reviews, establish reusable patterns and drive consistency across business units
• Be part of a global community of Principal Engineers / Distinguished Engineers / Engineering Fellows , shaping standards and sharing best practice

What you’ll bring

Proven track record as a Senior Staff / Principal / Senior Principal hands-on engineer (individual contributor)

• Strong software engineering fundamentals and excellent coding ability (repositories and technical reviews)
• Experience building and maintaining scalable cloud-based applications ( Azure preferred )
• Experience with big data technologies (e.g., Databricks, Spark )
• Ability to orchestrate and deliver complex change across teams and geographies
• Strong stakeholder management and the ability to explain complex engineering topics in an authoritative, actionable way
• Growth mindset, curiosity and a positive attitude to learning
• A strong STEM oriented background

Why this role is different

This is a pure engineering leadership role : your influence comes from your technical vision, credibility and delivery - not from managing people. You’ll work on problems where scale is real, stakes are high and outcomes protect customers and colleagues across the bank.
