Senior DevSecOps Engineer

The Team:

The Enterprise Developer Platform & Toolchain team owns the platforms, tools and capabilities that support software engineers across S&P Global. Our core functions span DevOps, DevSecOps, FinOps, Platform Engineering, Site Reliability Engineering (SRE) and Developer Experience (DevEx). We partner with divisional DevOps/TechOps teams and Information Security (InfoSec) to establish consistent controls and governance across the software development lifecycle (SDLC). As a globally distributed team, we build services, policies and automated controls that secure the developer toolchain while keeping platforms simple, consistent and engineer friendly.

The Impact:

You will embed security governance into the software delivery lifecycle by translating requirements into clear policies and automated controls. Your work will protect source control, CI/CD pipelines, build infrastructure and the software supply chain without creating unnecessary friction for engineers. You will strengthen credentials, secrets and non-human identity governance; drive security findings through to remediation; and contribute to AI-assisted development governance and developer endpoint security. Working with platform teams, divisional DevOps/TechOps teams and Business Information Security Officers (BISOs), you will support audit and compliance and make secure practices the default.

What's in It for You:

Help shape how thousands of engineers build and ship software securely. You will work hands-on with enterprise security tooling and emerging areas such as AI tool governance and policy as code. You will own controls end to end, from policy design to automated enforcement, and collaborate with InfoSec, audit and engineering leaders. We support your growth through innovation projects, training, certification support and knowledge sharing.

Responsibilities:

• Define and implement baseline security policies and automated guardrails across source control and CI/CD environments.
• Integrate, manage and tune code quality and application security tools, including SonarQube, GitHub Advanced Security (GHAS), Checkmarx and Wiz, within developer workflows.
• Triage security findings, prioritise vulnerabilities by risk and track remediation against service-level agreements (SLAs).
• Establish governance for credentials, secrets and non-human identities across the developer toolchain.
• Harden build infrastructure and software supply chain controls, including artifact management with JFrog Artifactory/Xray.
• Provision, secure and optimise AWS services supporting the developer platform, including EC2, ECS/EKS, Lambda, S3, IAM and CloudFormation/CDK.
• Contribute to governance for AI-assisted development tools and developer endpoint security.
• Monitor sensitive configuration changes, implement alerting and support audit and compliance activities.
• Partner with platform and engineering teams to automate security controls and drive adoption.

What We're Looking For:

• 5-8 years of experience in DevSecOps, application security or security governance.
• Strong experience designing and automating enterprise-scale CI/CD pipelines, with an understanding of source control security and common pipeline threats.
• Hands-on knowledge of GitHub Enterprise Cloud, GitHub Actions, runners, rulesets and policies.
• Strong understanding of repository lifecycle management and Git practices, including Conventional Commits, semantic versioning, trunk-based development/GitFlow and pull request workflows.
• Hands-on experience with static application security testing (SAST), software composition analysis (SCA), secrets scanning or cloud security tools.
• Ability to write clear security policies and standards and translate them into technical enforcement.
• Knowledge of identity and access management, including single sign-on (SSO), role-based access control (RBAC) and least privilege.
• Proficiency with infrastructure as code, including Terraform, CloudFormation or CDK, and familiarity with configuration management tools.
• Experience with AWS compute, networking, storage, IAM and container orchestration (ECS/EKS), including AWS security practices.
• Strong scripting and automation skills in Python or Bash; familiarity with TypeScript/Node.js.
• Understanding of configuration management databases (CMDBs) and ITIL-aligned change management, including approvals and audit trails.
• Awareness of AI tool governance and developer endpoint security, including mobile device management (MDM).
• Strong communication skills and the ability to influence adoption across engineering teams.

Nice to Have:

• Experience with AI-assisted development tools, including GitHub Copilot and Cursor IDE, and developer agents/MCP integrations.
• Contributions to open-source Backstage plugins or internal developer platform (IDP) ecosystems.
• Familiarity with compliance as code and policy engines such as OPA or Sentinel.
• AWS certifications, such as Solutions Architect or DevOps Engineer, or Kubernetes certifications (CKA/CKAD).
• Security certifications, such as CSSLP, Security+ or AWS Security.

Technical Environment:

• Source Control & CI/CD Security: GitHub Enterprise security features, GitHub Actions hardening, OIDC and GitHub Apps
• Application Security: SAST/SCA tooling, including Checkmarx, SonarQube and GHAS
• Cloud & Container Security: Wiz or similar cloud security posture management (CSPM) and vulnerability tools
• Software Supply Chain: Artifactory/Xray or similar tooling, software bills of materials (SBOMs) and artifact signing
• Secrets & Identity: Vault or other secrets managers, Okta or similar tooling, and non-human identity governance
• Runners & Endpoints: Runner hardening tools and MDM
• AI Governance: Copilot controls, MCP and agent guardrails
• Monitoring: Splunk or similar security information and event management (SIEM) tooling
• Automation & Cloud Security: Python, Bash, Terraform and AWS security (IAM, KMS)

Preferred Qualifications:

Bachelor's degree or higher in a technology-related field.
