• →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.

• 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.
