About the role

We are seeking a Security Analyst with strong investigation capabilities across endpoints (EDR/SIEM) and cloud environments (AWS, Microsoft Entra ID and O365). In addition, the candidate should bring an application security mindset to detecting and responding to threats affecting web applications, APIs and mobile applications.

The selected candidate will be responsible for (a) security monitoring and incident response, (b) cyber data analysis and automation, (c) vulnerability assessment, and (d) maintaining asset visibility and developing and improving security controls across our banking environment.

What you will do

Security Monitoring & Incident Response

• Continuously monitor security events across endpoints, cloud services, identities and applications to detect suspicious activity.
• Investigate incidents, establish timelines and impact, preserve evidence, and coordinate containment, remediation and recovery.
• Apply reverse-engineering techniques to suspicious applications, scripts and binaries to understand their behavior and support incident response.
• Use approved AI tools to assist with code analysis, artifact interpretation and investigation hypotheses, validating conclusions against source evidence.
• Document investigation findings, communicate incident status and next steps, and contribute to post-incident reviews and response playbooks.

Cyber Data Analysis & Automation

• Collect, normalize and correlate data from security controls on banking applications, EDR, SIEM, cloud infrastructure, cloud audit logs, identity platforms and application telemetry.
• Develop scripts and automated workflows for alert enrichment, evidence analysis, threat hunting and reporting.
• Identify data-quality and logging gaps that affect detection and investigation coverage.
• Use AI-assisted analysis to identify patterns and summarize findings while maintaining traceability, accuracy and protection of sensitive data.

Vulnerability Assessment

• Assess vulnerabilities across web applications, APIs, mobile applications, endpoints and cloud infrastructure.
• Validate findings, assess exploitability and business impact.
• Apply application security knowledge to identify weaknesses in authentication, authorization, session management, secure storage, payment transactions and business logic.
• Track remediation and verify that fixes address the underlying risks.
• Research emerging vulnerabilities and attack techniques to improve assessment and detection capabilities.

Asset Visibility & Security Controls

• Identify and document technology assets, ownership, criticality, data flows and dependencies.
• Develop and recommend risk-based security controls in collaboration with engineering and infrastructure teams.
• Oversee the security posture of systems through configuration reviews, access-control checks, asset inventories and monitoring of security-relevant changes.
• Evaluate control effectiveness, identify coverage gaps and recommend improvements to security monitoring and response procedures.

Requirements

Who we are looking for

Required

• Bachelor’s degree in Computer Science, Computer Engineering, Information Systems, Information Security or a related field, and/or 3+ years of relevant work experience.
• Practical experience in security operations and incident response across endpoint, cloud or application environments.
• Strong understanding of web, API and mobile application security, including authentication, authorization, session management, secure storage and common attack techniques.
• Familiarity with OWASP Top 10, API security risks and mobile application security principles.
• Practical reverse-engineering and malware-analysis skills, including familiarity with static and dynamic analysis techniques.
• Hands-on experience with EDR, SIEM, log analysis and security investigation tools.
• Hands-on vulnerability assessment experience and the ability to distinguish validated risks from scanner findings.
• Hands-on experience investigating security events across AWS and Microsoft Entra ID and O365.
• Understanding of asset inventory, security configuration, access controls and continuous monitoring.
• Experience using AI to support security analysis, investigations and scripting.
• Strong analytical, documentation and communication skills, including explaining technical findings and business impact to non-technical stakeholders.
