We would like to meet a Senior / Lead Conversational Experience Designer for a project with a hybrid working model:

This is a unique opportunity to join a growing AI ecosystem and help establish Conversational Experience as a design discipline at scale.

You’ll work at the intersection of UX, AI, content, voice, product and data, turning powerful AI capabilities into conversations that feel natural.

Your mission:

Your primary mission will be to:

• Design the conversational experience of the client priority AI agents, for both customers and employees

• Create conversations that are relevant, natural, consistent with the brand and measurable

• Define the principles, patterns and standards that will allow to scale conversational AI across new use cases

• Build a Conversational UX Guidelines / Pattern Library that becomes the reference for teams designing AI experiences

You will create a scalable Conversational UX Guidelines framework covering:

• External customer conversations — text

• External customer conversations — voice

• Internal employee experiences

• Reusable patterns for greetings, clarification, error recovery, sensitive data collection, closing and human handoff

• A conversational readiness checklist for new use cases

• Guardrails for uncertainty, lack of knowledge and safe agent behaviour

What we’re looking for:

Must-have experience:

• 5+ years of experience in UX, Product Design or a related design discipline

• 3+ years of hands-on Conversational Design experience, with conversational agents actually deployed in production

• Proven experience designing VUI / voice experiences, including IVR or voice assistants

• Experience working with GenAI / LLM-based agents, including prompt design, grounding, hallucination management and guardrails

• Experience creating UX guidelines, conversational design systems or pattern libraries adopted by other teams

• Excellent written communication in European Portuguese and English, with strong sensitivity to tone, clarity, conciseness and context

• Ability to interpret conversational data and connect the full cycle: design → measurement → iteration

It would be a strong plus if you have:

• Experience in telecom, banking, insurance, utilities or retail, particularly in high-volume transactional environments

• Knowledge of speech technologies, including ASR/TTS and speech recognition error handling

• Hands-on experience with conversational design platforms such as Voiceflow, Botpress or equivalent tools

• Experience working within organisations with an internal AI team, rather than exclusively delivering through external vendors

• Experience establishing new design standards or practices within large organisations

Find with us the right opportunity to grow!

What you can expect from us:

• Long-term projects with national and international context
• Opportunities to grow technically and professionally
• A people-first culture, focused on transparency and trust
• Teams that value ownership, collaboration and stability
