Our AI Voice & Telephony Engineering Team builds the systems that power intelligent conversations, using AI to create natural, human-like interactions at scale. We're building voice experiences that connect customers to the right solutions faster and more effectively. As a Software Engineer, you'll build and maintain scalable, cloud-based services that enable real-time voice interactions across our platform. You'll work with engineers, product managers, and data scientists to bring conversational AI into production.

What You'll Do

• Own end-to-end delivery of features, from technical design and implementation through testing, deployment, and monitoring.
• Build and maintain services that power call routing, speech processing, and AI-driven conversations using Twilio, AWS, Azure, and internal APIs.
• Work with product, data science, and other engineering teams to deliver AI-powered voice experiences.
• Contribute to architectural decisions and system design.
• Build solutions that are scalable, secure, and maintainable.
• Improve system performance, latency, and reliability across a distributed, event-driven stack.
• Participate in code reviews to maintain high standards and share knowledge.
• Improve tooling, automate repetitive work, and contribute to shared development practices.
• Participate in on-call rotations and troubleshoot production issues to keep services running reliably.

What We're Looking For

• 3+ years of professional software engineering experience.
• Experience with Twilio Voice, Programmable Voice APIs, or similar voice/IVR platforms.
• Experience integrating speech recognition, text-to-speech, or LLM-based conversational AI.
• Languages: Strong proficiency in Python and TypeScript/Node.js.
• Cloud Infrastructure: Experience building and operating services in AWS, such as Lambda, DynamoDB, S3, CloudWatch, or ECS/Fargate.
• APIs: Experience building RESTful APIs and working with event-driven systems.
• CI/CD: Experience with CI/CD pipelines, such as GitHub Actions, CircleCI, or similar.
• Testing: Experience writing automated tests, including unit and integration tests.
• Observability: Familiarity with monitoring and observability tools such as Datadog, New Relic, or OpenTelemetry.
• Databases: Familiarity with relational databases and a working knowledge of SQL.
• Strong analytical and problem-solving skills.
• Clear communication skills and experience collaborating across teams.

Nice to Have

• Familiarity with frameworks for building real-time voice and multimodal conversational AI agents, such as Pipecat, or LiveKit.
• Experience with WebSockets or messaging technologies such as SNS/SQS, Kafka, or Redis Streams.
• Understanding of serverless architectures.
• Experience with infrastructure-as-code tools such as Terraform or AWS CDK.
• Experience with load testing.
