Blanc Labs is a premier partner for global enterprises, leading the way in digitization, automation, and the development of next-generation digital products and services. Our expertise in digital transformation powers businesses to accelerate service delivery, drive customer engagement, and foster growth.

Alongside our client work, a small product team at Blanc Labs is building our own AI agent platform: agents that hold real conversations with customers across voice, SMS, and chat. The platform is already live in production with enterprise clients, and we operate with the pace and ownership of a startup, backed by the stability of an established firm. You’ll take features from idea to production and see them used by real clients.

We’re looking for a Software Engineer who wants to build across the whole stack (backend services, web interfaces, and the AI agents themselves) and gets energy from solving hard problems rather than already knowing every answer.

This is a hybrid role in downtown Toronto, with 2-3 days a week in the office.

Build and ship features across the platform: backend services,



APIs, and the Next.js interfaces our team and clients use

Develop agent capabilities, including prompt assembly, tool and function calling, streaming responses, and conversation state

Integrate real-time voice and messaging channels (telephony, SMS, web) alongside our technical lead

Design data models and migrations with care for consistency and safe change

2 to 5 years of professional software engineering experience, with production code you’ve shipped and supported

- Strong Python, including asynchronous programming (asyncio, FastAPI, or similar)
- Experience with React and TypeScript
- Comfort with relational databases (PostgreSQL), SQL, and migrations
- Hands‑on experience building with LLMs, professionally or through side projects
- A habit of figuring things out: reading the docs, testing hypotheses, and asking positive questions
