Senior DevSecOps Engineer

This is a Full Time Job

Location: (On-site / Hybrid / Remote - NY, Bay Area, Chicago, Greenville)
Department: Technology

About The Role

At MrBeast, we operate at massive scale - content, commerce, fintech, philanthropy, and global digital platforms. Security isn’t an afterthought. It’s a foundational capability.

We’re looking for a Senior DevSecOps Engineer to architect and scale a security-first engineering culture across our cloud infrastructure and CI/CD pipelines. This is not a reactive security role - this is a builder role.

You will embed security directly into our development workflows, automate detection and response at scale, and harden our AWS and GCP environments against evolving threats. You’ll partner deeply with Engineering, IT, and Compliance to ensure our systems remain resilient as we grow.

If you thrive on ownership, love automating everything, and want to build modern security infrastructure from the ground up - this role is for you.

What You’ll Do
Build Secure Infrastructure at Scale
- Design and implement cloud security guardrails across AWS and GCP.
- Embed policy enforcement and compliance checks directly into Terraform modules.
- Conduct architecture reviews and continuous hardening of multi-cloud environments.
- Lead threat modeling efforts for new infrastructure and product initiatives.
- Lead secrets management strategy (Vault, AWS Secrets Manager, GCP Secret Manager).

Embed Security Into the SDLC
- Integrate SAST, DAST, and dependency scanning into GitHub Actions workflows.
- Lead secure code review initiatives and drive secure-by-design engineering practices.
- Partner with engineering teams to eliminate vulnerabilities before production.

Detection Engineering & Threat Visibility
- Design, build, and tune high-fidelity detection logic within SIEM platforms.
- Map detections to MITRE ATT&CK and threat models.
- Improve signal-to-noise ratio through advanced alert tuning and correlation logic.
- Develop log aggregation and monitoring strategies across application and infrastructure layers.
- Conduct detection coverage gap analysis.

Automate Incident Response
- Build and maintain SOAR playbooks to automate repeatable response workflows.
- Reduce mean time to detect (MTTD) and mean time to respond (MTTR).
- Continuously improve response playbooks through post-incident analysis.

Partner With Compliance & GRC
- Automate evidence collection for audits and regulatory requirements.
- Translate security controls into technical enforcement mechanisms.
- Help scale compliance programs without adding operational overhead.

What You Bring
Required Experience
- 5 years in DevSecOps, Cloud Security, or Security Engineering roles.
- Deep experience securing AWS and GCP environments.
- Advanced Terraform expertise (infrastructure as code, modules, policy-as-code).
- Strong Python proficiency for automation, API integrations, and custom tooling.
- Hands-on experience with SIEM and SOAR platforms (design, integration, detection engineering).
- Deep familiarity with CI/CD security best practices and GitHub Actions.

Strongly Preferred
- Experience designing and managing identity architectures (Okta, Azure AD, or similar), including SSO, SCIM, lifecycle automation, and conditional access.
- Familiarity with Elastic SIEM or modern log aggregation platforms.
- Experience with EDR/XDR platforms (SentinelOne, CrowdStrike, Defender), including policy tuning and telemetry integration.
- Experience managing endpoint security controls and MDM solutions (Jamf, Intune, etc.).
- Experience securing Google Workspace environments.

What Success Looks Like
- Security is seamlessly embedded into every CI/CD workflow.
- Cloud environments are hardened with automated guardrails.
- Detection systems produce high-confidence, actionable alerts.
- Incident response workflows are automated and measurable.
- Compliance evidence collection is largely automated and audit-ready.

Why This Role Is Different
- You’ll own security architecture across multiple cloud environments.
- You’ll influence engineering standards across the company.
- You won’t be “reviewing tickets” - you’ll be building scalable systems.
- You’ll operate at the intersection of DevOps, Security, and Automation.
