• Build the custom Amazon Connect Streams API agent workspace to spec, covering chat handling, case history display, and iFrame integration of the Salesforce URL
• Implement the Microsoft Teams presence-sync intermediary component against the MS Graph API
• Contribute to IaC pipelines for Amazon Connect resources, using CloudFormation/CDK where possible and documenting manual steps where not
• Collaborate with the Salesforce Developer on Salesforce-side objects, REST API contracts, and validation
• Support QA with testable, documented components, and participate in SIT and defect resolution
• Contribute to knowledge-transfer documentation so the client's team can operate and extend the platform post-go-live

Requirements

• 5+ years of hands-on Amazon Connect experience, including contact flows, queues, routing profiles, and Connect APIs/SDKs, with the ability to build and debug contact flows independently
• Solid AWS Lambda experience with S3 trigger patterns, DynamoDB reads/writes, and REST API calls from Lambda
• Proficiency in JavaScript/Node.js or Python for Lambda development
• Familiarity with the Amazon Connect Streams API or the ability to ramp up quickly on it
• Experience integrating REST APIs, consuming and producing REST endpoints such as Salesforce, MS Graph, or similar CRM/enterprise APIs
• Experience working in a structured delivery team with a shared backlog, code reviews, and a fixed deadline
• Strong attention to detail and the ability to work independently once requirements are clear
• English proficiency at B2 level or higher

Nice to have

• Expertise in Microsoft Graph API, including presence, calendar, and user APIs
• Familiarity with Salesforce REST API or APEX for integration debugging
• Familiarity with Entra ID (Azure AD) SSO configuration
• Knowledge of IaC tools such as CloudFormation or CDK for AWS resource provisioning
• Background in the contact-centre domain or prior platform migration experience
