Reliability Engineer, High Voltage Systems

Versigent; Lisboa; On-site; EUR 90,000 - 120,000; Full time

Job summary

Altium Limited, a leading software company, seeks a Staff Product Security Engineer to advance product security through regression testing, threat modeling, and proactive offensive security.

You will design security regression suites, drive threat modeling across features, and perform Red Team‑style testing to identify real vulnerabilities before customers are affected. Collaboration with engineering is essential.

Qualifications

• 5+ years in Application / Product Security.
• Bachelor's Degree or equivalent of 12 years of work experience.
• Strong hands‑on experience in Web application security testing, API security, threat modeling methodologies, and deep understanding of OWASP Top 10.
• Experience with manual penetration testing, security regression testing, and CI/CD security integration.
• Ability to identify business logic vulnerabilities and understand authentication, authorization, session management, multi‑tenant architectures and cloud‑native systems.

Responsibilities

• Security Regression Testing: Design and maintain security regression test suites covering critical application flows.
• Ensure vulnerabilities, once fixed, are permanently prevented from recurring.
• Integrate security regression into CI/CD pipelines and define coverage targets for security-critical areas (auth, access control, APIs, data flows).
• Threat Modeling: Lead structured threat modeling sessions for existing system components and new features/architectural changes; identify attack surfaces, abuse cases, and trust boundaries.
• Translate threats into test cases, security requirements, and mitigation plans; ensure threat modeling becomes a continuous lifecycle activity.
• Offensive Security / Red Team Activities: Perform manual and automated security testing simulating real attacker behavior; focus on high-impact vulnerabilities and validate exploitability and business impact.
• Partner with engineering teams to reproduce issues, prioritize fixes, and validate remediation.

Job Description
Why A365 Software Engineering?
Build the cloud platform that transforms electronics design.

Altium 365 for cloud lets design engineers communicate, collaborate and bring their ideas to market more efficiently than any platform in the industry.

We are looking for a Senior Product Security Engineer to extend our Product Security capability with a strong focus on continuous vulnerability discovery and prevention.

This role is responsible for:

• Building and executing security regression testing
• Driving threat modeling across existing and new functionality
• Conducting targeted offensive security activities (Red Team-style testing)
• Identifying real vulnerabilities based on a deep understanding of our platform and the OWASP Top 10 Web Application Security Risks

The goal is simple: ensure that both existing functionality and new changes remain secure over time, and that real vulnerabilities are discovered before customers do.

Key Responsibilities

• Security Regression Testing
• Design and maintain security regression test suites covering critical application flows
• Ensure vulnerabilities, once fixed, are permanently prevented from recurring
• Integrate security regression into CI/CD pipelines
• Define coverage targets for security-critical areas (auth, access control, APIs, data flows)
• Threat Modeling
• Lead structured threat modeling sessions for:
• Existing system components
• New features and architectural changes
• Identify attack surfaces, abuse cases, and trust boundaries
• Translate threats into:
• Test cases
• Security requirements
• Mitigation plans
• Ensure threat modeling becomes a continuous lifecycle activity
• Offensive Security / Red Team Activities
• Perform manual and automated security testing simulating real attacker behavior
• Focus on high-impact vulnerabilities, not theoretical findings
• Validate exploitability and business impact
• Partner with engineering teams to:
• Reproduce issues
• Prioritize fixes
• Validate remediation

OWASP Top 10-Driven Vulnerability Discovery

• Continuously assess the platform against OWASP Top 10 categories
• Use deep product knowledge to find non-obvious, context-specific vulnerabilities
• Go beyond tooling (DAST/SAST) to uncover logic flaws and abuse paths

Security Assurance for Product Changes

• Review new features and changes for security risks
• Ensure all changes are:
• Threat-modeled
• Covered by regression tests
• Act as a security gatekeeper without becoming a bottleneck:
• Enable teams with guidance and tooling
• Avoid heavy process overhead

Collaboration & Enablement

• Work closely with:
• Engineering teams
• Architecture
• SRE / Platform teams
• Contribute to secure-by-design practices
• Support developers in understanding and fixing vulnerabilities
• Help scale security through:
• Reusable patterns
• Automation
• Security guidance
