Responsibilities

• Own and mature the DevSecOps program with guardrails across CI/CD pipelines.
• Threat-model new services and translate findings into actionable guardrails for developers.
• Create reusable IaC patterns and templates adopted by engineering teams.
• Triage and remediate findings across cloud and app layers; reduce backlog.
• Establish cloud security guardrails on AWS; extend to Azure with Defender and Policy.
• Harden IAM, network exposure, and encryption; enforce least privilege.
• Extend posture mgmt to Azure and/or GCP controls.

Job description

We are global private markets specialistsdelivering tailored investment solutions,advisory services, and impactful, data driveninsights to the world’s investors.Leveraging the power of our platform andour peerless intelligence across sectors,strategies, and geographies, we helpidentify the advantages and the answersour clients need to succeed.

The DevSecOps Engineer is responsible for embedding security into the software development lifecycle and the firm's CI/CD pipelines, with primary focus on application security guardrails, developer-facing tooling, and secure engineering practices. The role also maintains hands-on cloud security expertise, primarily on AWS with working proficiency across Azure, to harden posture and reduce exposure. Sitting within Infrastructure Engineering, the role partners closely with application development, platform, and DevOps teams to build guardrails that get adopted rather than imposed, protecting systems and data while supporting delivery speed.

Key Responsibilities

• Own and continuously mature the firm's DevSecOps program, embedding SAST, DAST, SCA, infrastructure-as-code and secrets scanning, and policy gates directly into CI/CD pipelines to catch issues before deployment.
• Partner with application development teams to threat-model new services and features at design time, translating findings into concrete guardrails and remediation guidance developers can act on.
• Build and maintain secure-by-default patterns, reusable infrastructure-as-code modules, and golden pipeline templates that engineering teams adopt by default.
• Operationalize the firm's cloud-native application protection platform (Wiz): triage, prioritize, and remediate findings across cloud and application layers, reducing backlog and mean time to remediate.
• Establish and codify cloud security guardrails primarily on AWS, including Service Control Policies, Config rules, public-access blocking, default encryption, and tagging baselines.
• Harden identity and access (IAM roles, policies, permission boundaries, and least privilege) and network exposure across cloud workloads.
• Extend posture management and guardrails to Azure, using tools such as Microsoft Defender for Cloud, Azure Policy, Entra ID, and equivalent GCP controls.
• Drive down internet-facing exposure, targeting zero critical and high-severity findings across public-facing workloads and applications.
• Provide security evidence and controls in support of SOC 2, audit, and regulatory requirements, with emphasis on evidencing secure SDLC practices.

Required Skills

• Strong, hands-on experience embedding security into CI/CD pipelines and the SDLC: SAST, DAST, SCA, infrastructure-as-code scanning, secrets management, and policy-as-code/gating.
• Practical application security background, including threat modeling and secure coding guidance, with a track record of working directly with developers to land fixes without becoming a blocker to delivery.
• Solid, hands-on AWS security expertise (IAM, VPC and network security, KMS and encryption, Service Control Policies, public-exposure controls), plus working proficiency in Azure and/or GCP security (Entra ID, Azure RBAC, Microsoft Defender for Cloud, Azure Policy, or equivalent GCP services).
• Proficiency with infrastructure-as-code (Terraform and/or CloudFormation; Bicep or GCP Deployment Manager an advantage) and scripting and automation (Python preferred).
• Solid understanding of core security processes, including vulnerability management, logging and detection, secrets management, and incident support.
• Experience operating a CNAPP/CSPM platform (Wiz preferred), with a track record of remediating findings rather than only reporting them.
• Familiarity with container and Kubernetes security (EKS/AKS/GKE) and AI/ML application security is desirable.

Educations and Or Work Experience Requirements

• Bachelor's degree in Computer Science, Information Security, or a related field.
• Four (4)+ years of experience in DevSecOps, application security, or cloud security engineering.
• Professional certifications such as a DevSecOps or application security credential (e.g., GWEB, Certified DevSecOps Professional), AWS Certified Security - Specialty, or equivalent.
• Prior exposure to audit and compliance standards including SOC 2, ISO 27001, or SOX.
