Full Job Description

đź“‹ Description

  • • Partner with engineering and product teams to embed security practices from the earliest stages of feature design, including participation in design reviews and threat modeling.
  • • Balance delivery speed with security requirements by communicating risks clearly to non-technical stakeholders and determining appropriate trade-offs between velocity and security posture.
  • • Identify, assess, and mitigate security risks introduced by AI tools, AI-generated code, and AI system integrations across the development lifecycle.
  • • Apply AI-assisted tooling (e.g., GitHub Copilot, Claude Code) to accelerate security tasks including code review, vulnerability triage, threat detection, and documentation generation.
  • • Configure, tune, and maintain SAST, SCA, and DAST security tooling within CI/CD pipelines built on GitHub Actions or Azure DevOps YAML.
  • • Conduct risk and vulnerability assessments of web applications, APIs, third-party suppliers, and integrations to ensure secure third-party dependencies.
  • • Collaborate with external penetration testing firms to validate findings, prioritize remediation efforts, and track resolution progress.
  • • Assist in implementing and refining security alerting, detection rules, and automation workflows to improve incident response and reduce manual toil.
  • • Support operational security initiatives including EDR alerts, MDM configurations, and corporate IT security process improvements.
  • • Deliver and facilitate security training sessions for developers and cross-functional teams to build organizational security awareness and capability.
  • • Contribute to the evolution of Karbon’s security roadmap by identifying gaps, proposing solutions, and measuring progress through defined security metrics.
  • • Work across multiple security domains with flexibility—ranging from cloud infrastructure reviews to application security assessments to corporate endpoint security.
  • • Build trust and relationships across the organization to foster a culture of shared security ownership and proactive collaboration.
  • • Take full ownership of security outcomes, ensuring high-quality, reliable, and customer-impacting solutions from design through post-release support.
  • • Maintain up-to-date knowledge of emerging security technologies and foundational practices such as least privilege, MFA, account hygiene, and attack surface reduction.
  • • Bring authenticity, curiosity, and creativity to the team, contributing positively to a culture of transparency, low bureaucracy, and mutual respect.
  • • Help shape Karbon’s AI-enabled engineering culture by confidently integrating AI tools into security workflows while upholding strong technical fundamentals.

🎯 Requirements

  • • 4+ years of experience in security or development roles with hands-on work in application security, cloud security, and secure software development practices
  • • Proven experience collaborating with engineering teams to review designs, implement security controls, and remediate vulnerabilities
  • • Working knowledge of at least one major cloud platform (Azure, AWS, or GCP), with Azure preferred
  • • Proficiency in at least one programming language or framework: .NET/C#, JavaScript (React/EmberJS), or Python
  • • Experience using AI-assisted development tools such as GitHub Copilot, Claude Code, or similar
  • • Demonstrated ability to configure and tune SAST, SCA, DAST tools and integrate them into CI/CD pipelines

🏖️ Benefits

  • • Flexible Time Off with encouragement to use at least 4 weeks per year
  • • Company-paid medical, dental, and vision coverage for employee and eligible dependents
  • • 401(k) with company matching
  • • Up to 8 weeks paid parental leave
