Be sure to explore our Interviewing Guide to learn how to ace our interview process. About the Role Twitch's Enterprise Platform & Technology (EPT) organization is looking for a Software Development Engineer II to build the systems where SAP meets AWS — extending our enterprise ERP with cloud-native services and agentic AI to power Finance and enterprise functions across Twitch and Amazon. This is a hands-on engineering role where you'll work on SAP-side development (ABAP, CDS, RAP, OData) and AWS-native engineering (Lambda, Step Functions, MCP servers, Bedrock, CDK) — owning integrations end-to-end. You'll work at the intersection of SAP enterprise systems and modern cloud engineering — building AWS-hosted APIs and pipelines that talk to SAP, standing up agentic AI tooling (MCP servers, Bedrock agents, Claude-powered workflows) that automates Finance operations, and shipping production AWS services alongside SAP customizations. The business problems are well understood; how you solve them with SAP + AWS + AI is up to you. We're looking for an SAP developer whose toolkit has grown past the ERP — someone who writes ABAP inside SAP GUI and is just as ready to pick up Python or TypeScript to ship the cloud half of their own integration, and who raises the bar on automation along the way. You Will Build in SAP Design, build, and maintain integrations between SAP (S/4HANA, BTP) and downs
