Design and implement security tooling and controls in a cloud environment to protect the organization’s data and systems across mobile devices, workstations, servers and SaaS technologies.

Requirements:

3–5+ years of experience in security engineering, cloud security, or infrastructure/network security.
Experienced in writing automation scripts in Python, Powershell, or Bash.
Working knowledge of protocols such as DNS, HTTPS/S, TLS, and LDAP.

Experience configuring and securing AWS GovCloud, Azure Government, or similar regulated cloud platforms.
Understanding of the MITRE ATT&CK Framework and its application to threat hunting.
Experience working with vulnerability management programs in compliance-driven environments.
Clear and concise technical writing skills, with the ability to produce documentation suitable for audits and assessments.

Preferred Qualifications:

Experience supporting, maintaining, or engineering for a FedRAMP-authorized system.
Experience working with incident response.
Background in generating SSPs, POA&Ms, ConMon evidence, or system architecture documentation.
Automation experience related to compliance workflows, evidence gathering, or configuration drift detection.
Certifications such as Security+, CySA+, CASP+, CCSP, CISSP, or related.

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.

US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
