• Architect systems that manage real-time conversation state, context propagation, and session lifecycle.
• Implement seamless AI-to-human handoff mechanisms, ensuring full context transfer and minimal disruption to the customer experience.
• Develop secure and reliable integrations with CCaaS APIs (voice, chat, messaging, routing, agent desktop, etc.).
• Collaborate closely with ML engineers and AI researchers to operationalize AI Agent capabilities in live environments.
• Ensure high availability, low latency, and strong observability for real-time conversation systems.
• Implement authentication, authorization, compliance, and enterprise security best practices across integrations.

About the role

• Build real-time AI agent infrastructure: Design and operate the stateful, low-latency runtime that powers voice and chat AI agents — from LLM streaming and conversation state management to graceful recovery and multi-channel support.
• Solve distributed systems problems: Own session management across scaled-out workers — including affinity, checkpointing, crash recovery, and consistency under concurrent access.
• Build a function execution platform: Own a serverless-style runtime where customers deploy custom logic — build orchestration, container lifecycle, autoscaling, and versioned rollouts.
• Own developer experience and test infrastructure: Build CLI tools, local development environments, and test execution frameworks that let engineers iterate quickly and ship with confidence.
• Raise the bar on production quality: Drive observability, incident response, and engineering best practices across the team.

• 5+ years of software engineering experience, with meaningful time spent on infrastructure, platform, or systems work.

• Experience with Kubernetes and cloud-native infrastructure.
• Experience building developer-facing tooling — CLIs, SDKs, local dev environments, or internal platforms.
• Strong communicator who can drive technical decisions, write clear design docs, and mentor others.
• High bar for code quality — thorough testing, thoughtful code review, and sustainable engineering practices.
• Comfort operating what you build — on-call, incident response, and production ownership.
• AI-native workflow — you actively use LLMs and AI-assisted tools in your daily development, and can leverage them to move faster and tackle problems that would otherwise be impractical.

• Experience with real-time voice or streaming media systems.
• Hands-on with LLM integration — streaming inference, prompt orchestration, retrieval-augmented generation.
• Experience building serverless or function-as-a-service platforms.
• Workflow engines (Temporal, Argo, Airflow) for durable, long-running processes.
• Experience in conversational AI or speech domains.
