About Chasi

The Role

• Ship production features across the entire platform: voice agents, workflow automation, memory architecture, and the customer-facing UI
• Design and build the real-time voice pipeline: response delivery in sub-second latency
• Evolve our memory system: vector stores that make every agent conversation contextually intelligent
• Build integrations that enterprises actually need: Salesforce, HubSpot, and custom CRM connectors
• Architect multi-tenant infrastructure that scales from 10 to 10,000 organizations
• Make direct technical decisions: model selection, infrastructure tradeoffs, build vs. buy, etc

• 1+ years of internships building production software, ideally full-stack TypeScript/React with real backend depth
• Waterloo Interns: Final internship
• You've worked with LLMs beyond the tutorial stage: prompt engineering, tool use, embeddings, retrieval-augmented generation
• Comfortable in real-time systems: WebSockets, streaming, audio pipelines, or telephony infrastructure
• Strong opinions on architecture, loosely held. You make tradeoffs fast because you've shipped enough to know what matters
• You thrive in ambiguity. You talk to customers, identify what to build, and ship it
• Ownership mentality — this is a founding role with founding-level equity and founding-level responsibility
