Senior Platform Engineer

The Team:

The Enterprise Developer Platform & Toolchain team owns the developer platforms, tools and capabilities that support software engineers across S&P Global. Our core functions are DevOps, DevSecOps, FinOps, Platform Engineering, SRE, and Developer Experience (DevEx). We partner with divisional DevOps/TechOps teams and InfoSec to establish consistent controls and governance across the SDLC. As platform owners, we define and implement policies and controls that secure developer tools without disrupting the developer's experience. We build services and processes that enable DevOps practices across the company and use DevEx insights to keep our platforms simple, consistent, and engineer friendly. The team is globally distributed.

The Impact:

You will build and operate tooling and automation that give engineers a fast, secure and consistent software delivery experience across S&P Global. You will administer and evolve enterprise source control and CI/CD platforms, applying governance and standards as code. Using APIs and webhooks, you will build automation, reusable workflows and integrations to reduce manual effort across the SDLC. You will design internal developer portal capabilities, including service catalogues, templates and self-service workflows, and integrate security, quality and artefact management tools with minimal friction. By automating identity, access and onboarding processes and supporting adoption through documentation, you will improve developer experience and accelerate engineering productivity.

What's in It for You:

Do you enjoy building platforms that engineers use every day and seeing the productivity gains first-hand? You will work with GitHub Enterprise Cloud, GitHub Actions reusable workflows, Azure DevOps, AWS, Terraform, Backstage, Artifactory/Nexus and SonarQube, using Python, TypeScript/Node.js and Bash. You will help shape our internal developer portal and self-service strategy and develop developer productivity metrics. You will collaborate with security, IT and engineering teams across the company and own solutions from design through production. We support your growth through innovation projects, training, cloud and Kubernetes certifications, and knowledge sharing.

Responsibilities:

• Design, implement, and maintain CI/CD pipelines and DevOps tooling across GitHub Enterprise Cloud, Azure DevOps (ADO), and GitHub Actions hosted runners to ensure reliable, fast, and secure software delivery.
• Administer and evolve the source control platform (GitHub Enterprise Cloud), including repository governance, branch policies, access controls, and enterprise-level configurations.
• Manage the repository lifecycle (creation, ownership, archival) and enforce version control best practices (Conventional Commits, semantic versioning, branching, PR standards).
• Design and support internal developer portal capabilities such as service catalogues, templates, and self-service workflows.
• Build and operate cloud-based services and infrastructure that support the developer platform.
• Integrate security, quality, and artefact management tools into developer workflows with minimal friction.
• Automate identity, access, and onboarding processes in partnership with security and IT teams.
• Own and operate AI-assisted development tooling including GitHub Copilot, Cursor IDE, developer agents, and MCP (Model Context Protocol) integrations - driving adoption, measuring productivity impact, and scaling usage across engineering teams.
• Provision, secure, and optimise AWS services (EC2, ECS/EKS, Lambda, S3, IAM, CloudFormation/CDK) that underpin the developer platform infrastructure.
• Build automation frameworks and developer agents that eliminate toil - automating onboarding, environment setup, compliance checks, and repetitive platform operations.
• Collaborate with engineering, security, and architecture teams to define platform standards, enforce guardrails, and drive continuous improvement across the developer experience.
• Produce clear documentation, runbooks, and enablement material to drive self-service adoption and reduce support burden.

What We're Looking For:

• 5-8 years of experience in software engineering, platform engineering, DevOps, SRE or infrastructure engineering roles.
• Strong hands-on experience with GitHub Enterprise Cloud (administration, Actions, hosted runners, GHAS) and Azure DevOps.
• Deep expertise in CI/CD pipeline design and automation at enterprise scale.
• Strong understanding of the repository lifecycle and Git best practices (Conventional Commits, semantic versioning, trunk-based/GitFlow, PR workflows).
• Proficiency with infrastructure-as-code (Terraform, CloudFormation, CDK) and configuration management tools.
• Solid experience with AWS services - compute, networking, storage, IAM, and container orchestration (ECS/EKS).
• Understanding of CMDB and change management (ITIL-aligned change requests, approvals, audit trails).
• Experience building or extending Internal Developer Portals (Backstage, Port, or similar).
• Familiarity with ServiceNow (workflow/catalogue configuration) and data platforms (Databricks or equivalent).
• Strong scripting and automation skills (Python, Bash, TypeScript/Node.js).
• Excellent understanding of Git workflows, branching strategies and developer collaboration practices.
• Strong communication skills with the ability to influence adoption across engineering teams.

Nice to Have:

• Experience with AI-assisted development tools (GitHub Copilot, Cursor IDE) and developer agents/MCP integrations.
• Hands-on experience building developer productivity metrics and dashboards (DORA, SPACE frameworks).
• Contributions to open-source Backstage plugins or IDP ecosystems.
• Experience with FinOps practices and cloud cost optimisation for platform infrastructure.
• Familiarity with compliance-as-code and policy engines (OPA, Sentinel).
• Certifications in AWS (Solutions Architect, DevOps Engineer) or Kubernetes (CKA/CKAD).

Technical Environment:

• DevOps & CI/CD: GitHub Enterprise Cloud, Azure DevOps, GitHub Actions & Hosted Runners, SonarQube, JFrog Artifactory
• AI Developer Tooling: GitHub Copilot, Cursor IDE, Developer Agents, MCP Integrations
• Internal Developer Portal: Backstage, Port
• Cloud & Infrastructure: AWS (EC2, ECS/EKS, Lambda, S3, IAM, CDK/CloudFormation)
• Workflow & Data: ServiceNow (Service Catalogue, Change, CMDB), Databricks (Data Lake)
• Automation: Python, TypeScript/Node.js, Bash, REST/GraphQL APIs, webhooks, SQL databases, Terraform

Preferred Qualifications:

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