Senior Software Security Engineer (DevSecOps)

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). This role is primarily hybrid, with occasional travel to our Krakow office. 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). 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. • Good verbal and written English communication. 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. In return for your expertise, we’ll support you in this new challenge with coaching & development every step of the way. Also, to reward the hard work, you’ll get: • Contract of Employment (UoP) • Private medical coverage, Multisport • Life insurance (two annual incomes),  • Employee Stock Purchase Plan – 15% discount for buying Motorola’s Stock units,  • Employee Pension Plan – 3,5 % of the month’s salary gross, which goes to the retirement account • IP Tax Relief (up to 50%) • Yearly salary increase (depends on individual performance) • Yearly bonus (depends on company performance) • UK working hours (working day between 10-18),  • 8 hours working day (30 minutes lunch break included). • Hybrid/ remote work
