Cloud Security Engineer

The Cloud Security Engineer secures the platform that hardware engineering teams trust to ship every day. You'll own the security engineering layer of Duro's modern stack—cloud security posture, detection and threat hunting, security telemetry, and the security infrastructure that protects multi-tenant, dedicated, and regulated (GovCloud/ITAR) environments. This is a security-first role on a small, fast-moving team reporting into the CISO organization, where you'll partner closely with platform engineering, product, and compliance to make security an accelerator rather than a gate. We're looking for an engineer who thinks in adversaries and systems, automates relentlessly, and leverages modern AI-augmented workflows to build defenses that scale. This is a hybrid role based in Los Angeles, CA (3 days per week in office).

A day in the life of our Cloud Security Engineer:

• Cloud Security Engineering: Design and operate the security posture of Duro's AWS commercial and GovCloud environments—IAM and least-privilege access models, KMS/encryption policy, VPC segmentation, network controls, and secure-by-default guardrails across accounts and tenants.
• Threat Detection & Hunting: Proactively hunt across cloud, application, and identity telemetry for anomalous and adversarial behavior. Build and tune detections as code, reduce false positives, and turn hunt findings into durable, automated coverage.
• Threat Intelligence: Operationalize threat intelligence—integrate feeds, contextualize indicators and TTPs against Duro's attack surface, and drive proactive hardening ahead of emerging threats.
• Logging, Monitoring & Reporting: Architect and administer centralized logging, SIEM, and security monitoring across the stack. Own alerting pipelines, dashboards, and the security metrics and reporting that inform leadership, customers, and compliance evidence.
• Security Infrastructure Implementation & Administration: Implement, administer, and continuously improve the security tooling estate—CSPM, vulnerability management, endpoint and workload protection, secrets management, and cloud-native security services (GuardDuty, Security Hub, CloudTrail, Config, WAF, Inspector).
• Application & Pipeline Security: Embed security into the SDLC and CI/CD—secure GitHub Actions pipelines, integrate SAST/DAST/SCA, enforce secrets hygiene, and secure container and Kubernetes workloads from build through runtime.
• Security as Code: Build reproducible, version-controlled security infrastructure and guardrails using Terraform, policy-as-code, and containerization—so controls are enforced automatically and drift is caught early.
• Compliance-Driven Controls: Partner with CISO leadership to implement and evidence controls mapped to SOC 2, ITAR, and GovCloud requirements, translating framework obligations into concrete technical enforcement.
• AI-Driven Security Engineering: Leverage AI-augmented workflows to accelerate detection engineering, triage, and control implementation while maintaining rigorous validation and review standards.
• Incident Response: Support detection, investigation, containment, and post-incident hardening—reducing mean time to detect and respond, and feeding lessons learned back into automated coverage.

Required:

• 5+ years of hands-on experience in security engineering, cloud security, or DevSecOps with production ownership of security controls and infrastructure
• Bachelor's degree in Computer Science or related field (or equivalent practical experience)
• Deep AWS security expertise—IAM, KMS, VPC/network security, GuardDuty, Security Hub, CloudTrail, Config, WAF—including hands-on experience across commercial and GovCloud environments
• Demonstrated experience in threat detection and threat hunting across cloud, application, and identity telemetry, including detection engineering / detection-as-code
• Experience operationalizing threat intelligence to drive proactive defense
• Strong background in logging, monitoring, and security reporting—centralized logging, SIEM design and administration, alerting, dashboards, and metrics
• Experience implementing and administering security infrastructure and tooling (CSPM, vulnerability management, secrets management, workload/endpoint protection)
• Application and pipeline security experience—securing CI/CD (GitHub Actions), SAST/DAST/SCA integration, secrets management, and securing containerized/Kubernetes workloads
• Infrastructure-as-code proficiency with Terraform and containerization tools such as Docker, applied to security guardrails and controls
• An innovative, adversarial mindset—you anticipate how systems break and automate the defense before it's needed
• Strong systems thinking and the ability to design scalable, secure, maintainable controls
• Excellent written and verbal communication skills
• Comfort operating in autonomous, fast-paced environments

Nice to Have:

• Relevant certifications (AWS Security Specialty, CISSP, OSCP, GCIH/GCIA/GCFA, or similar)
• Experience with DuploCloud or similar tenant/cloud management platforms
• Knowledge of compliance frameworks such as SOC 2, FedRAMP, ITAR, or CMMC
• Experience building security for PLM, PDM, or hardware/manufacturing industry software
• Background supporting compliance-driven or regulated (GovCloud, on-premises) deployments
• Incident response, digital forensics, or purple-team experience
• Familiarity with observability tooling such as Datadog, PostHog, or Sentry, and event-driven systems (NATS, Redis, Kafka)
• PostgreSQL and Kubernetes operational familiarity sufficient to secure and reason about those workloads

How We Build

We don't just ship features. We build platforms that make shipping inevitable—and secure by default.

At Duro, AI is integrated into our engineering and security workflows. Engineers leverage AI-powered environments to orchestrate tasks, structure context, and accelerate delivery and defense while maintaining high standards of operational and security excellence.

We value:

Adversarial intuition — understanding how systems fail and how attackers think before building the defense Detection over hope — coverage you can measure, tune, and trust, expressed as code Precision in communication — clear control design produces reliable, auditable systems Pattern recognition — knowing when to abstract, automate, or simplify Operational discipline — building controls that are observable, resilient, and self-healing Intellectual curiosity — continuously improving how we secure and scale

We optimize for engineers who can build security that fades into the background—enabling teams to deploy daily with confidence, not friction.

The expected annual pay range for this position is $150,000-$160,000. This position is also eligible for bonus opportunities. Please note that final offer amount will be dependent on geographic location, applicable experience, and skillset of the candidate.
