Job description
We are seeking a DevSecOps Engineer to join our Engineering team. This role is critical to securing, hardening, and scaling the infrastructure that powers our platform across cloud-hosted production environments.
This engineer will work closely with platform, infrastructure, and security stakeholders to improve the security and operational maturity of our AWS and Kubernetes environments, support compliance and audit readiness, and help ensure our systems are reliable, secure, and maintainable as we grow. This role will also support environments serving regulated and security-sensitive customer needs, including an environment we host for a Government organization.

Design, implement, and maintain secure, scalable infrastructure in AWS
Manage, secure, and improve Kubernetes-based environments, including production workloads
Build and maintain infrastructure as code using Terraform
Harden production systems across cloud, compute, container, identity, and network layers
Develop and maintain secure baseline configurations for infrastructure and platform services
Support vulnerability management, patching, remediation, and configuration compliance efforts across environments
Configure, administer, and patch both Linux and Windows VMs
Support identity and access management practices, including least privilege, role design, and privileged access controls
Contribute to administration and integration of Active Directory domains where needed
Partner with engineering teams to improve security within CI/CD pipelines, deployment workflows, and operational processes
Support compliance initiatives, audits, evidence collection, and technical control validation
Develop and maintain documentation, operational runbooks, technical standards, and playbooks
Monitor, troubleshoot, and resolve complex infrastructure and security issues with clear and timely communication
Participate in incident response and post-incident analysis when infrastructure or platform issues arise
Stay current on cloud, infrastructure, and security best practices that can improve platform resilience and delivery
Required Qualifications
Minimum of 5 years of experience in DevOps, DevSecOps, Infrastructure Engineering, Platform Engineering, or Security Engineering
Strong hands-on experience with AWS in production environments
Proven experience with Kubernetes, preferably in production
Strong experience with Terraform and infrastructure-as-code practices

Experience configuring and maintaining both Linux and Windows virtual machines
Strong understanding of IAM, secrets management, network security, logging, monitoring, and operational controls
Proven experience improving or securing CI/CD pipelines and deployment workflows
Excellent troubleshooting and problem-solving skills in complex production environments
Strong communication skills with the ability to explain technical concepts to both technical and non-technical stakeholders
Must live/work in the U.S.
Preferred Qualifications
Experience supporting environments with regulated, compliance-driven, or security-sensitive requirements
Familiarity with compliance or security frameworks such as SOC 2, NIST, ISO 27001, CMMC, or similar
