Application Developer - Conversational AI & Voice Systems

Full-Stack | Cloud | Real-Time Systems

About the Role

We're hiring a Application Developer to join a fast-growing Communication Platforms organization building next-generation conversational and telephony experiences used by customers at scale. This team owns mission-critical systems across voice, SMS, virtual agents, and contact-center integrations, and plays a direct role in shaping how customers interact with the business.
You'll join a small, high-impact Natural Language & Automation (NLA) team-a tight-knit group where each engineer has meaningful ownership. In this role, you'll help design and build real-time, AI-driven conversational systems that stream live voice, understand caller intent, intelligently route interactions, and seamlessly blend human and virtual agents.
This is a true full-stack role with deep exposure to telephony, conversational AI, cloud infrastructure, and hands-on DevOps. Prior telephony experience is a plus, but not required-strong engineering fundamentals, curiosity, and the ability to learn complex real-time systems are highly valued.

What You'll Do

  • Design, build, and maintain high-availability, enterprise-grade applications supporting real-time voice and conversational AI use cases
  • Develop AI-powered virtual agents that:
    • Understand why a customer is calling
    • Determine call disposition (routing, callbacks, human handoff)
    • Operate with low latency for natural, human-like interactions
  • Stream and process live voice data in responsive, resilient, and scalable systems
  • Build internal tools for prompting strategies, call analytics, workflows, and orchestration
  • Collaborate closely with product, analytics, and engineering partners
  • Work across telephony services, contact-center platforms, SMS, and conversational workflows
  • Own services end-to-end, including:
    • System design and architecture
    • Development and testing
    • Deployment, monitoring, and production support
  • Operate in a team-owned DevOps environment, including AWS and Kubernetes (EKS)
  • Troubleshoot and resolve high-impact production issues with confidence and clarity
  • Contribute to a culture that values ownership, collaboration, and high technical standards

What We're Looking For

Core Qualifications
  • Full-stack engineering experience with strong system design instincts
  • Hands-on backend development using Golang and/or Python
  • Experience with distributed, real-time, event-driven, or low-latency systems
  • Strong experience with AWS and Kubernetes (EKS) and comfort owning DevOps responsibilities
  • Proven ability to build, support, and troubleshoot production-grade systems
  • Curiosity, resilience, and enthusiasm for learning complex domains such as telephony and conversational AI

Front-End & Platform Experience
  • Modern web development with JavaScript, TypeScript, and React
  • API design and backend services development
  • Experience with NoSQL databases (MongoDB or similar)
  • CI/CD pipelines, Docker, and cloud-native development practices

Nice to Have (Strong Plus)

  • Experience with VoIP / telephony systems
  • FreeSWITCH development experience
  • Event-driven architectures and streaming systems
  • Linux systems experience
  • Infrastructure as Code (Chef, AWS CDK, Troposphere)
  • OAuth2 / authentication & authorization flows
  • CRM integrations
  • Exposure to conversational AI, prompting strategies, or real-time AI systems
  • Experience working in Agile / Scrum environments

Why This Role

  • Join a small, high-ownership team where your work directly shapes customer experience
  • Build cutting-edge conversational AI and voice systems developed in-house
  • Make a real impact by reducing phone friction and creating more natural, human interactions
  • Strong opportunity for long-term growth and conversion to permanent employment
  • Collaborative engineering culture with exposure across multiple initiatives
