Senior Software Security Engineer

This role is primarily hybrid, with occasional travel to our UK offices, likely to be Uxbridge / London.

Responsibilities

Security Design and Implementation

• 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.

Security Testing

• 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.

Vulnerability Management

• 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 (i.e. non-applicable) 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.

SDLC and DevSecOps Integration

• 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.

Incident Response and Compliance

• Support product security incident response processes, including root cause analysis (identify the affected product components, data, and the overall impact level) 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 reocurring, 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).

Basic Requirements

Required Qualifications

Experience and Education

• 5+ years of experience in Security Engineering with a focus on product security and/or application security.
• Bachelor’s degree in Computer Science, Information Security, or a related technical field.

Technical Skills

• In-depth knowledge of Linux and Docker container-based infrastructures, including their orchestration (e.g. Kubernetes).
• Working knowledge of techniques, standards, and state-of-the-art authentication and authorization technologies, applied cryptography, security vulnerabilities and remediations.
• Significant software development experience. Experience in Go (our main backend language), Typescript/Javascript, C/C++, Python and Bash is desirable.
• Working knowledge of web-related protocols and technologies (HTTP, REST APIs, DOM, CSP), networking protocols (IP, TCP, UDP), and security protocols (TLS).
• Experience in performing threat modeling, with a good grasp of common threat vectors and frameworks.
• Strong knowledge of security principles, best practices, and industry standards, such as NIST, ISO 27001, and CIS Critical Security Controls, OWASP ASVS and Testing Guides.
• Familiarity with industry-standard security frameworks such as OWASP and NIST.
• Experience with security tools such as SAST, DAST, IAST, and SCA.
• Exceptional analytical and investigative skills, with hands-on experience in root cause analysis.
• Knowledge of current and emerging threats and techniques for exploiting security vulnerabilities.
• Experience with CI/CD pipeline, security tools integration, and secure SDLC.
• Experience with cloud-based infrastructure (AWS, Azure, or Google Cloud), and on best practices on how to secure cloud environments.

Desirable Qualifications

Advanced Expertise

• Familiarity with security considerations for AI/ML systems is desirable.
• Understanding of distributed systems design, implementation and operation.
• Understanding of privacy threats and controls, including on how to adapt generic best practices to specific scenarios in the product by providing detailed specifications to stakeholders.
• Exploit development experience, and good understanding of the necessary conditions to trigger different vulnerability types, and the maximum impact achievable.
• Experience with enterprise log collection and analysis platforms (e.g., Splunk, OSQuery).

Education and Certifications

• Master's degree or equivalent experience preferred.
• Security certifications are a plus, including OSCP, OSEE, SANS/GIAC, CCSP, and CISSP.

Soft Skills and Leadership

• Excellent verbal and written communication, with the ability to translate complex security concepts to technical and non-technical stakeholders.
• Demonstrated ability to design, document, and implement new security processes.
• Experience in a high-growth technology environment or SaaS business.
• Ability to remain calm under pressure, especially during incidents or audits.
