What You’ll Do:

As a Senior Software Engineer, you’ll design and build scalable, cloud-based systems that enable real-time voice interactions across our platform. You’ll lead the development of core services that blend AI, telephony, and automation, helping shape how people communicate with our brands.

You’ll also:

• Own the design and delivery of new features end-to-end — from architecture and implementation to deployment and observability.
• Work with product managers, AI engineers, and data scientists to bring conversational intelligence into real-world voice experiences.
• Integrate deeply with Twilio, AWS, Azure, and internal APIs to manage call routing, speech processing, and response flows.
• Improve system performance, latency, and reliability across a distributed, event-driven stack.
• Provide technical leadership — mentoring other engineers, sharing knowledge, and helping shape best practices across the team.
• Participate in code reviews and on-call rotations, ensuring production systems run smoothly and efficiently.

What We’re Looking For:

• Languages: Strong proficiency in Python and TypeScript/Node.js.
• Cloud Infrastructure: Deep experience with AWS (Lambda, DynamoDB, S3, CloudWatch, ECS/Fargate, etc.).
• Telephony: Hands-on experience with Twilio Voice, Programmable Voice APIs, or similar voice/IVR platforms.
• APIs: Skilled in designing RESTful and event-driven APIs (WebSockets, SNS/SQS, or Kafka/Redis Streams experience a plus).
• CI/CD: Proficient with modern DevOps workflows (GitHub Actions, CircleCI, or similar).
• Testing: Strong commitment to automated testing (unit, integration, and load testing).
• Familiarity with observability stacks (Datadog, New Relic, or OpenTelemetry).
• Databases: Familiarity with relational databases and basic working knowledge of SQL.

Nice to Have:

• Experience integrating speech recognition, text-to-speech, or LLM-based conversational AI.
• Familiarity with frameworks for building real-time voice and multimodal conversational AI agents (e.g., Pipecat, Livekit, etc.).
• Understanding of serverless architectures and event-driven systems.
• Experience with infrastructure-as-code tools (Terraform or AWS CDK).
• Familiarity with React, Next.js, or other front-end frameworks (for internal dashboards or call management tools).
• Telephony: Hands-on experience with Twilio Voice, Programmable Voice APIs, or similar voice/IVR platforms.
