Job Summary

Senior DevSecOps Engineer - Enterprise Developer Platform and Toolchain 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 across S&P; Global.

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.

Requirements

- 5-8 years of experience in DevSecOps, application security or security governance.
- Robust 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.
