Senior Production Support Engineer

What You'll Be Doing & Why It Matters

MuleSoft Security Engineering protects the Anypoint Platform and the infrastructure it runs on. As a Senior Security Engineer focused on infrastructure, you will design, build, and operate identity, network, and cloud security controls in AWS.

You will work in a FedRAMP environment and meet its security control requirements. Federal regulations restrict access to this environment to U.S. citizens working from the U.S.

Core Responsibilities & Scope

• Implement and maintain security controls that satisfy FedRAMP requirements, mapped to NIST SP 800-53.
• Engineer secure network architecture in AWS: VPC design, segmentation, security groups, NACLs, Transit Gateway, PrivateLink, WAF, and egress controls.
• Design and improve identity and access management: IdP integration, SSO, federation (SAML, OIDC, OAuth), IAM roles and policies, least privilege, privileged access, secrets management, and KMS key management.
• Build and maintain infrastructure as code in Terraform, including reusable modules, secure defaults, policy-as-code, and automated guardrails.
• Harden and secure Linux systems and containers, including host baselines, runtime security, and Kubernetes workloads.
• Support continuous monitoring: vulnerability remediation within required timelines, POA&M tracking, and evidence collection for audits.
• Automate control validation and evidence gathering.
• Partner with Engineering, SRE, and Compliance to embed security into the SDLC and deployment pipelines.
• Contribute to incident response and detection engineering, including logging, SIEM integration, and alerting.
• Produce clear technical documentation and architecture reviews, and mentor other engineers.

Minimum Requirements

• 5+ years in security engineering, cloud security, or infrastructure security.
• Experience implementing and meeting security controls in a FedRAMP environment, or an equivalent framework (for example, NIST 800-53, NIST 800-171, or CMMC).
• Solid knowledge of NIST security controls, including control families, baselines, and how to map them to technical implementations.
• Strong, hands-on Terraform skills, including module design, state management, and CI/CD-driven deployments.
• Deep experience with network security engineering in AWS (VPC, Transit Gateway, security groups, WAF, GuardDuty, Security Hub, Config, CloudTrail).
• Hands-on identity engineering: IdPs, SAML, OIDC, OAuth 2.0, and directory and authentication protocols (LDAP, Kerberos), plus AWS IAM and KMS.
• Strong understanding of TLS and PKI, including certificate lifecycle management and secure protocol configuration.
• Strong Linux systems and container experience.
• Proficiency in a scripting language (Python, Go, or Bash).
• Strong written and verbal communication, including working with auditors and engineering teams.
• U.S. citizenship and the ability to work from the U.S., as required by federal regulation for access to the FedRAMP environment. Willingness to complete additional screening or background checks as required.

Preferred Qualifications

• Practical experience using AI tools to accelerate engineering work, with sound judgment in reviewing AI-generated code and configurations for security.
• Experience supporting a FedRAMP authorization, annual assessment, or 3PAO assessment.
• Experience with Kubernetes security at scale.
• Working knowledge of vulnerability management, patching, and remediation workflows.
• Familiarity with FIPS 140-2/140-3 validated cryptography.
• Experience with AWS GovCloud.
• Experience with FedRAMP 20x, continuous monitoring automation, OSCAL and/or similar frameworks and technologies.
• Familiarity with CISA directives and DISA STIGs.
• Experience with policy-as-code (OPA, Sentinel, Checkov) and software supply chain security.
• Certifications such as AWS Security Specialty, CKS, CCSP or similar is preferred.

What Success Looks Like

• First 90 days: You understand the infrastructure architecture and control inventory, and you own remediation of a defined set of control gaps.
• 6 months: You deliver network and identity security improvements through Terraform and automate at least one control validation workflow.
• 12 months: You are a recognized technical authority for AWS infrastructure security and compliance, and you help keep the team audit-ready.
