AWS Telephony / IVR Application Developer
Job Summary
We are seeking an experienced AWS Telephony / IVR Application Developer to design, develop,
deploy, and support Amazon Connect–based IVR solutions. This role focuses on building and
maintaining IVR contact flows and serverless services, implementing secure configuration and
secrets management, and ensuring high quality through resilient design and validation of failure
scenarios (e.g., timeouts, API failures, dependency degradation).

Key Responsibilities
Amazon Connect & IVR Development
 Design, build, deploy, and version Amazon Connect Contact Flows.
 Configure and maintain Amazon Connect resources including:
o Queues
o Routing profiles
o Hours of operation
 Develop and integrate Lex bots where applicable.

 Design and utilize DynamoDB access patterns supporting IVR use cases (e.g., routing
state, transfer points, lookup/stateful interactions).
Secure, Configurable Development
 Build software that:
o Reads configuration externally (not hard-coded)
o Uses managed secrets (no embedded credentials)
o Supports release promotion without code changes
 Ensure no hard-coded:
o Endpoints
o Credentials
o Environment identifiers
Deployment & Delivery Practices
 Deploy application artifacts using standardized CI/CD pipelines (no manual console
deployments).
 Contribute to and follow a documented deployment runbook for consistent, repeatable
releases across application components.

 Collaborate with QA and stakeholders to ensure enhancements meet quality standards
before promotion.

o DynamoDB
 Experience building telephony/IVR experiences, including failure-safe behavior and
degraded-mode handling.
 Experience with secure secrets and configuration management (e.g., AWS Secrets
Manager and/or Parameter Store).
 Experience delivering via CI/CD pipelines using standardized deployment patterns.
