Your expertise in AWS Lambda will be essential, you'll develop Lambda functions to automate business logic, integrate systems, and power the intelligence behind our contact center workflows.
While you may not have direct Amazon Connect experience, your solid foundation in backend development, Lambda, API integrations, and AWS will allow you to quickly master this technology.
RESPONSIBILITIES

- Workflow Logic Implementation: Translate business requirements into complex logical workflows using Triggers and Automations. Ensure routing logic handles edge cases effectively.
- Testing & Validation: Conduct rigorous unit testing of all configurations. Partner with Quality Engineers to execute System Integration Testing (SIT) and support User Acceptance Testing (UAT), specifically troubleshooting API failures or routing logic errors.
- Documentation & Knowledge Transfer: Create detailed "as-built" documentation, API mapping documents, and runbooks. Assist in the handover process to the client's operations team by providing technical walkthroughs of the implemented solution.
- Post-Deployment Support: Provide hyper-care support immediately following go-live, troubleshooting bugs, optimizing system performance, and assisting with rapid configuration adjustments.
