Junior Prompt Engineer

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

• 1+ years of hands-on experience working on AI/ML or conversational AI projects — ideally in fintech, telecom, startup
• Proven experience with prompt engineering: writing and iterating prompts for LLMs for real product use cases
• Experience designing end-to-end conversational flows for chatbots or AI agents, including intent recognition, dialogue trees, fallback handling, consumer copywriting
• Experience with prompt testing / QA and AI Observability tools (LangSmith, etc)
• Experience with prompt iterating and evals (prompt engineering + test cases + human-in-the-loop)

Nice to have

• Background in UX Design or UX Research - strong plus!
• AI Voice experience
• Background in business process analysis: ability to translate complex workflows into clear, structured dialogue scenarios

• 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.

• 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
