- AWSPythonKubernetesCI/CDTerraform
Requirements
- 5+ years of hands-on experience in security engineering with an emphasis on building engineered systems.
- At least 1 year of production experience with at least 2 agentic coding tools (e.g., Claude Code, Gemini, Cursor, Codex).
- Proven track record building and shipping production code in Python.
- Deep familiarity with infrastructure-as-code tools such as Terraform.
- Experience in cloud-native environments, specifically AWS (KMS, IAM, Lambda, EKS) and Kubernetes.
- Understanding of CI/CD pipeline integration and containerized workloads.
- Strong software engineering fundamentals including version control, code review, and API design.
- Knowledge of PKI concepts and certificate lifecycle management.
- Familiarity with security telemetry platforms (e.g., OpenSearch).
- Bachelor's degree in Computer Science, Cybersecurity, Software Engineering, or equivalent experience.
Responsibilities
- Engineer the security infrastructure the rest of the company depends on across AWS and Kubernetes: telemetry pipelines, cryptographic material lifecycle, compliance automation, and the architecture patterns that scale across hundreds of environments.
- Build and maintain agentic AI workflows using tools like Claude Code, MCP-based integrations, and custom agent harnesses to automate security engineering tasks.
- Engineer the lifecycle of cryptographic material as code, including key generation, secure storage, certificate issuance, rotation, and revocation.
- Build security telemetry pipelines that detect, enrich, and route signals with the fidelity our auto-remediation systems require.
- Embed security controls into deployment pipelines so vulnerabilities are prevented or resolved at build time.
- Build compliance evidence collection and continuous control monitoring as engineered systems that produce auditor-ready outputs.
- Develop and maintain threat models that inform security architecture decisions.
- Consult, review, and approve architectural decisions by other infrastructure and product teams for security compliance.
- Provide engineering support to Security Operations during incident response.
- Evaluate emerging AI-assisted engineering patterns and tooling through proof-of-concept work.
