What the job involves

• The Senior Software Security Engineer will be responsible for analysing software designs and implementations from a security perspective, identifying and proposing remediations to security issues throughout the software development lifecycle (SDLC)
• Perform threat modelling, risk assessments, and architecture reviews to identify and mitigate risk
• Support the engineering teams on definition on detailed security requirements to meet compliance requirements and industry best practices
• Perform security code reviews looking for potential security vulnerabilities
• Act as a subject matter expert to advise and answer questions from engineering and compliance teams on technical product security matters
• Define and oversee the deployment of Software Composition Analysis (SCA) tools to compile SBOMs of software components, helping to identify known vulnerabilities and license compliance violations
• Define and oversee the deployment of automated security testing tools into CI pipelines, including Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Secret Detection scanning tools
• Manual penetration testing of web applications (backend and frontend). Manual penetration testing skills in the domains of cloud infrastructure, embedded/OS or mobile are desirable
• Write custom scripts or unit test cases to check for vulnerabilities or broken/missing security controls
• Recommend improvements to existing security scanning tools and processes, and propose new ones
• Periodically triage the findings from the automated security scanning tools
• Validate potential security vulnerabilities to determine whether they are actual true positives, or false positives in the product context. Write proof of concept exploits when necessary to achieve this
• Assess the risk of vulnerabilities and threats in order to help the business determine their remediation priority order
• Communicate the identified security issues to engineering and compliance stakeholders, and manage them throughout the SDLC process to ensure they are properly addressed
• Establish and maintain secure coding standards, baseline product security requirements and more general best practices to provide guidance to development teams
• Assist the program area with implementing a secure Continuous Integration/Continuous Delivery (CI/CD) pipeline utilizing DevSecOps principles and practices to increase automation
• Implement automated security controls as part of CI/CD pipelines
• Support product security incident response processes, including root cause analysis and definition of mitigation strategies
• Define clear criteria and protocols for security incident response
• Conduct post-incident analysis to compile lists of lessons learned, and measures to prevent similar incidents from reoccurring, and refine response strategies
• Monitor emerging security threats, vulnerabilities, and trends to proactively investigate, remediate, and integrate new protections
• Ensure products comply with relevant security standards, certifications, and regulations (e.g., OWASP, NIST)
