Staff Engineer

Caribou helps homecare organizations attract, engage, and retain staff through data-driven recognition, rewards, and coordination tools that make the lives of patients and their caregivers better. We're a small company of ~50 people who are mostly based in the GTA.

We are building on our core product such as deploying AI-powered agentic systems that work alongside agency coordinators to handle routine coordination, outreach, and administrative workflows to improve agency operations. We are hiring a Staff Engineer to help build and scale these systems: foundational infrastructure for autonomous, voice-enabled, multi-step workflows handling shift coordination, caregiver outreach, and intelligent scheduling.

What you'll do:

• Leverage and extend our AI Agent Platform: most new product surfaces will be built on top of our in-house multi-agent system.
• Expand what's possible with our AI Voice Agents: inbound and outbound call handling, webhook-based state resumption, async orchestration.
• Build observable, durable infrastructure with async state management and graceful failure handling.
• Design stateful, multi-step AI workflows: you understand failure modes, retry strategies, and how to build resilient agentic systems.
• Establish engineering patterns and mentor engineers across the agentic stack.
• Translate ambiguous home care workflows into automated systems.

Requirements:

• 8+ years of software engineering experience, including hands-on work with production LLM/agent systems.
• Strong TypeScript/JavaScript with hands-on experience with Temporal, LangGraph, or comparable frameworks.
• End-to-end architecture ownership and production monitoring.
• Leadership and mentoring capabilities.
• Comfortable working with ambiguous operational workflows.

Bonus:

• Stateful multi-step AI workflow design.
• Voice AI platforms (Vapi / Twilio / Retell).
• Durable execution frameworks.
• Regulated domain experience.

Tech stack: TypeScript/Node.js, Vercel AI SDK, AWS Bedrock, Vapi, Temporal, Terraform, AWS, PostgreSQL, Snowflake, GraphQL, React, Datadog, Sentry.

Location: Toronto, ON (Hybrid, 1 day/week in-office).
