Working from the Software/Core IT side of the transformation, you will focus on connecting Google Workspace , SaaS platforms, enterprise AI tools, and GM's core business systems through secure, reusable, and scalable integration patterns. You will independently deliver complex integration solutions, translate business and technical requirements into practical system designs, and build production-ready pipelines that align to enterprise standards. You will partner closely with product, engineering, TPM, security, and business teams to enable reliable data flow, workflow continuity, and platform interoperability across GM. What You'll Do * Establish reusable patterns by defining and building GCP-native integration templates, accelerators, and reference implementations that reduce redundant engineering efforts across transformation pods. * Apply platform guardrails by aligning integration architectures with enterprise data standards, identity guidelines, and security policies. * Partner with Security, Privacy, Identity, and Information Lifecycle Management (ILM) teams to secure workflows that process regulated or sensitive data. * Evaluate incoming integration requests and recommend the right technical path (standard SaaS configuration, GCP-native services, or custom engineering). * Design, build, and maintain robust APIs, webhooks, and middleware pipelines connecting GCP with Workday, ServiceNow, and core internal systems. * Define source-to-destination data mappings, transformation logic, exception handling, and monitoring models that support reliable operations. * Modernize legacy and Microsoft-dependent interfaces into scalable, event-driven, Google-aligned integration patterns. * Build end-to-end workflows that orchestrate data movement and trigger actions across HR, IT, and internal enterprise ecosystems. * Design coexistence approaches that allow Microsoft, GCP, and internal environments to interoperate effectively during phased migration waves. * Coordinate data cutover sequencing, permissions validation, metadata mapping, and post-deployment stabilization to reduce business disruption. * Partner with Product Leads and Technical Program Managers to embed GCP-native integration capabilities into real-world operational processes. * Provide technical leadership through design reviews, architecture guidance, and engineering best practices across the program. * Deliver technical designs, dependency maps, runbooks, and handover materials that support long-term sustainment of integrated solutions. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [The Cloud is Calling: Answer with In-Demand Skills](https://www.wearedevelopers.com/videos/945-the-cloud-is-calling-answer-with-in-demand-skills) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [Delegating the chores of authenticating users to Keycloak](https://www.wearedevelopers.com/videos/1558-delegating-the-chores-of-authenticating-users-to-keycloak) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) ## Related Articles - [Got AI ideas but no money?
