Senior DevOps Engineer

Malwarebytes is looking for..

We are looking for a sharp, security-minded Senior DevOps Engineer to join our Consumer team. You will architect and manage our AWS infrastructure using Terraform, enforce cloud security best practices at every layer, make cost-conscious infrastructure decisions that balance performance with efficiency, and drive modern CI/CD automation across the organization. You will own site reliability for our production systems and contribute to the Build & Release processes that keep our development teams moving fast. If you hold security and reliability to a high standard and default to automation over manual process, we want to hear from you.

What You Will Do:

• Own and evolve our AWS cloud infrastructure using Terraform, applying security best practices — least-privilege IAM, network segmentation, secrets management, and compliance guardrails — as non-negotiable defaults.
• Design, implement, and continuously improve CI/CD pipelines using GitHub Actions, ensuring automated security scanning (SAST, secrets detection, container image scanning), policy enforcement, and quality gates are built into every pipeline.

• Champion infrastructure security: proactively identify and remediate cloud misconfigurations, leverage GuardDuty, Security Hub, and Config, and partner with the Security team on vulnerability management and incident response.

• Own and improve SRE practices: define SLOs, build alerting and observability solutions using CloudWatch and related tooling, and drive blameless post-mortems.

• Participate in on-call rotation and own production incidents end-to-end — from detection through resolution and follow-up.

• Maintain build and release environments for development teams and develop automation and test tooling for client applications.

• Evaluate and adopt emerging DevOps technologies through structured proof-of-concept testing.

• Keep documentation, runbooks, and architecture diagrams current and actionable.

Skills You'll Need to Have:

• 6+ years of hands-on DevOps or SRE experience in AWS — EC2, ECS, ECR, Lambda, RDS, CloudWatch, IAM, VPC, EKS, and CloudFront required. 
• BA/BS in Engineering or Computer Science preferred; equivalent experience demonstrated through a proven track record accepted. An ideal candidate holds one or more AWS Professional-level certifications (Solutions Architect Professional, DevOps Professional, or equivalent). 

• Deep Terraform expertise: you write modular, reusable, well-tested infrastructure code and treat IaC security as seriously as application security.

• Strong GitHub Actions experience building pipelines as code, including integrated security scanning (SAST, secrets detection, and container image scanning). Jenkins experience is a plus.

• Demonstrable cloud security depth: hands-on experience with GuardDuty, Security Hub, Config, SCPs, and related tools and practices.

• Strong scripting and automation — Python, Go, or Bash — with a track record of eliminating manual toil.

• Solid Linux system administration and container management (Docker). Windows Server and Windows container experience is a plus.

• Proven SRE practice experience: SLO definition, observability design, and post-mortem-driven reliability improvement.

• Familiarity with cross-platform code compilation (Windows and macOS), code signing, and software supply chain security.

• Active, daily use of AI coding assistants (Claude Code, GitHub Copilot, or equivalent) is expected as a core part of this role — you treat these tools as a force multiplier and stay current with how AI is reshaping DevOps and SRE workflows.

• Strong communication and documentation skills: capable of writing architecture proposals, leading design reviews, and producing runbooks that on-call engineers can act on under pressure.

Perks & Benefits:

• Comprehensive medical, dental, and vision insurance coverage 

• Employee Referral Bonus Program   

• Wellness programs    

• An opportunity to do something great for yourself and the world!
