This is a builder's role with unusual range. One week you're designing the architecture of a system nobody at Jobber has built before; the next you're embedded with a team, shipping working AI into their real workflow and making them the hero. You'll make fast build-vs-buy calls, run POCs and kill them without sentiment, and set the technical standards that everything AI at Jobber gets held to. We're looking for someone who has shipped production AI or data systems, defaults to pragmatic technology choices, and wants founding-engineer ownership with a real company's resources behind it. The Principal Software Engineer, AI will: * Architect and build new internal AI systems end to end, from first design to production, as the founding engineer. * Own the hard parts of trustworthy AI at company scale: retrieval quality, permissions, security, and reliability. * Work hands-on across the modern AI stack (LLMs, retrieval, agents, integrations) while keeping the foundations deliberately pragmatic. * Embed with teams across the company, working day-to-day with function leaders and their teams and weekly with executive leadership, shipping AI into real workflows and leaving behind systems and owners that outlast the visit. * Drive build-vs-buy evaluations and fast POCs, with the judgment to commit hard and kill fast. * Work directly with executive leadership: what you build informs how the company makes decisions, every day. ## Related Videos - [Agentic employees in world's most downloaded FinTech app](https://www.wearedevelopers.com/videos/100123-agentic-employees-in-world-s-most-downloaded-fintech-app) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Creating Industry ready solutions with LLM Models](https://www.wearedevelopers.com/videos/899-creating-industry-ready-solutions-with-llm-models) - [Beyond Dashboards: Fixing Text-to-SQL with Semantic RAG](https://www.wearedevelopers.com/videos/2036-beyond-dashboards-fixing-text-to-sql-with-semantic-rag) - [The Data Mesh as the end of the Datalake as we know it](https://www.wearedevelopers.com/videos/156-the-data-mesh-as-the-end-of-the-datalake-as-we-know-it) - [Azure AI Foundry for Developers: Open Tools, Scalable Agents, Real Impact](https://www.wearedevelopers.com/videos/1541-azure-ai-foundry-for-developers-open-tools-scalable-agents-real-impact) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this)
