We're expanding our Prompt Engineering team and are looking for a Conversational Designer to join us!

Requirements

• Native Portuguese speaker — this role involves designing and writing conversational content entirely in Portuguese; native-level fluency is mandatory • 2–3+ years of hands-on experience working on AI/ML or conversational AI projects — ideally in fintech, telecom, or retail • Proven experience writing and iterating prompts for LLMs (GPT, Claude, Gemini, or similar) for real business use cases • Experience designing end-to-end conversational flows for chatbots or AI agents, including intent mapping, dialogue trees, and fallback handling — experience with RASA is a strong plus • Background in business process analysis: ability to translate complex workflows into clear, structured dialogue scenarios • Strong written communication skills — you will be writing production-level bot copy and prompt instructions, not just specs • Python scripting skills are a plus

Responsibilities

• Analyze how business processes work on the client side: study internal instructions for employees, as well as real conversation recordings and transcripts; • Based on this analysis, design scripts and prompts for AI agents to automate these processes; • Create training and test data sets; • Develop and apply methodologies to assess the quality of the AI agents’ performance and use them to refine the agents.

What We Offer

• The team has built award-winning AI products for tech corporations — devices, voice assistants, products that are actually in the world • Cutting-edge tech stack: Speech Technologies, NLP, Generative AI (LLMs, diffusion models), voice-first agentic architecture with privacy-first and on-premises deployment • High engineering bar and real ownership — the team cares about what actually works in production, not what looks good in a demo, and you'll see the impact of your work directly • Fast career progression — a senior-heavy team and a high volume of real problems means you grow faster than you would anywhere else • Startup pace with enterprise stability — real clients, real revenue, no bureaucracy • Fully remote across Europe • 21 vacation days + public holidays + 5 sick days • Private English lessons via Preply
