What You'll Do
- Design, build, and maintain security-focused software components, services, and tools used across GM’s application ecosystem.
- Develop automation frameworks and internal platforms that make it easy for product teams to adopt secure patterns (e.g., identity, authorization, secrets management, logging).
- Integrate security controls and checks into CI/CD pipelines, build systems, and cloud-native deployment workflows.
- Architect and implement resilient, scalable security services and APIs (e.g., authentication, authorization, policy evaluation, event ingestion).
- Collaborate with application, infrastructure, and platform engineering teams to embed security requirements into system and service designs.
- Perform secure code reviews, threat modeling, and design reviews to identify and remediate vulnerabilities early in the SDLC.
- Build and maintain systems for security telemetry: logging, metrics, and alerting that support detection, triage, and incident response.
- Contribute to incident response and post-incident reviews as an engineering owner for security services and tooling.
- Stay current with emerging security threats, vulnerabilities, and technologies, and translate them into concrete engineering requirements, patterns, and roadmaps.
- Provide technical mentorship on secure coding, design patterns, and security architecture to other software engineers.
- Your Skills & Abilities (Required Qualifications):
- Bachelor’s degree or higher in Computer Science, Software Engineering, Cybersecurity, or a related technical field (or equivalent practical experience).
- 7+ years of experience as a software engineer building and owning production systems or in-house applications.
- Advanced proficiency in at least one modern programming language (for example: Python, Go, Java, or C++) with a strong understanding of software engineering fundamentals (data structures, algorithms, design patterns).
- Experience using AI-assisted development tools (for example, GitHub Copilot, Cursor, or similar) as part of day-to-day engineering workflows.
- Experience designing, implementing, and operating services on a major cloud platform (AWS, Azure, or GCP), including use of managed services and infrastructure-as-code.
- Hands-on experience with containerization and orchestration technologies (e.g., Docker, Kubernetes).
- Solid understanding of core security concepts as applied to software engineering, including:
- PKI including cert issuance, management.
- Encryption in transit and at rest, key/secrets management.
- Secure coding practices, input validation, and common vulnerability classes (e.g., injection, XSS, CSRF, insecure direct object references).
- Experience partnering with security and audit/compliance teams and translating security requirements into engineering work.
- Proven ability to plan and manage work in an Agile environment, taking ownership of features and services from design through production.
- Strong written and verbal communication skills, with the ability to explain identity and security concepts to both technical and non-technical audiences.
- What Can Give You a Competitive Advantage (Preferred Qualifications):
- Extensive experience designing and operating PKI and cryptographic services at enterprise scale.
- Experience modernizing and automating security platforms for broad adoption across engineering teams.
- Proven technical leadership, setting direction and influencing across organizations.
- Strategic thinker and champion of change who balances security with business needs.
- Strong integrity, accountability, and communication skills.
