Our expertise in digital transformation powers businesses to accelerate service delivery, drive customer engagement, and foster growth.\nAlongside 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.\nThe problems are real and hard, from making voice conversations feel natural to keeping them reliable in real-world conditions.\nWe’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.\nThis is a hybrid role in downtown Toronto, with 2-3 days a week in the office.\nWhat You’ll Be Doing\nBuild and ship features across the platform: backend services, APIs, and the Next.js interfaces our team and clients use\nDevelop agent capabilities, including prompt assembly, tool and function calling, streaming responses, and conversation state\nIntegrate real-time voice and messaging channels (telephony, SMS, web) alongside our technical lead\nDesign data models and migrations with care for consistency and safe change\nBuild background jobs and outbound processing with clear retry and failure handling\nInstrument services with logging, metrics, and tracing, and debug issues end to end, from the interface to the live conversation\nBring ideas to the roadmap and prototype new agent capabilities\nWhat You’ll Need To Be Successful\n2 to 5 years of professional software engineering experience, with production code you’ve shipped and supported\nStrong Python, including asynchronous programming (asyncio, FastAPI, or similar)\nExperience with React and TypeScript\nComfort with relational databases (PostgreSQL), SQL, and migrations\nHands-on experience building with LLMs, professionally or through side projects\nWorking knowledge of Docker and a major cloud platform (Azure preferred)\nA habit of figuring things out: reading the docs, testing hypotheses, and asking good questions\nNice to Have\nExperience with Next.js\nReal-time media or telephony (WebRTC, SIP, programmable voice or SMS APIs)\nLLM evaluation or agent frameworks\nExperience working within data residency or compliance
