We’re not just building software – we’re on a mission to create space for contractors & tradespeople by equipping them with AI solutions that work the way they do: fast, practical, and AI-first. With Tier 1 Investors from Europe and the US, like Headline and Creandum as well as 30,000+ tradespeople as customer base, we’re scaling across Europe to turn scattered tradespeople into thriving communities. We believe in zero admin, not zero personality – and we build every feature with the people in mind who wear the boots, not the suits. We’re #stoked to shape the future, #together as a team, and #humble in our mission to support the builders of tomorrow. YOUR MISSION AT PLANCRAFT This role is central to advancing plancraft’s AI product, PORTA, our voice-first digital receptionist that handles, structures, and automates customer communication for tradespeople. You will join the dedicated PORTA team and take ownership of evolving our AI Frontdesk Capabilities. From shaping and iterating on new AI-driven features to deploying them into production. Working closely with Product and Design, you will build and scale real-world AI features that operate reliably across channels and deliver measurable value to our customers. As part of a small, autonomous squad (1 Product Manager, 1 UX Designer, 4 Engineers), you’ll contribute hands-on while also shaping technical direction. You’ll work at the intersection of LLMs, voice interfaces, and product experience, turning state-of-the-art capabilities into robust, user-centric solutions used daily by thousands of businesses. Your
Responsibilities Lead the development and continuous improvement of AI-driven features, leveraging LLMs and voice technologies across multiple communication channels. Design, build and operate scalable systems on GCP, using React in the frontend and serverless Node.js / Express services in the backend — all in TypeScript. Shape and evolve AI capabilities by iterating on prompts, evaluations, and system behavior to deliver consistent, high-quality user outcomes. Drive architectural decisions and set engineering standards to ensure long-term scalability, maintainability, and performance. Take end-to-end ownership of features — from scoping and technical design to delivery, monitoring, and iteration based on real user feedback. Improve developer experience by advancing tooling, workflows, and codebase quality (e.g. refactoring, AI-assisted development, testing practices) within your team and across the entire engineering organization. Mentor and support engineers through hands-on collaboration, code reviews, and knowledge sharing, in an individual contributor role without formal people management
