We're hiring a Product Designer to help shape the future of conversational commerce 🚀 At Turn.io, we're building the tools that enable businesses to create meaningful chat experiences that genuinely impact people's lives. We're looking for a senior Product Designer who thrives on solving complex, never-before-tackled problems and wants to make their mark at a funded startup in its founding years. What you'll be doing: You'll own the design process from discovery to delivery, contributing to product strategy while conducting user research and evolving our design system. Working cross-functionally with engineers, you'll ensure your designs are both impactful and feasible. Since we don't have Product Managers, you'll have the agency to drive work autonomously and help establish our design culture. We're looking for someone who is: 1| Experienced in leading design for complex interactive applications at small or early-stage companies 2| Mission-driven and cares more about collective impact than portfolio pieces 3| User-centric with a research-first mindset and strong advocacy for users 4| Product-minded and skilled at balancing great UX with technical feasibility and business impact 5| Autonomous and capable of self-management while working on high-priority initiatives 6| End-to-end strong, from user research to polished visual design 7| Collaborative and believes the best ideas come from working with others 8| Technical with understanding of front-end development and hands-on building experience 9| Someone who loves the craft and delivers excellence in visual, UI, and interaction design What we offer: 100% remote work, flexible hours, "Calm Fridays" (half-day Fridays!), 4 weeks PTO plus local holidays, stock options, and yearly company retreats in beautiful locations worldwide. Ready to design tools that enable others to build impactful chat services? We'd love to hear from you. turn.io/careers/senior-produ… #productdesign #productdesigner #opportunity #job #socialimpact #startup #product

Tja, @MinPres Schoof bleef in zijn persconferentie keer op keer zeggen: “Er was en is geen sprake van racisme”. Bij mij kwam direct het beeld uit 2003 naar boven van Saddam Hussein’s woordvoerder; die de val van Bagdad keer op keer bleef ontkennen. 👇🏼

When Iranian police attacked a girl at Tehran University for not following the hijab rule, she removed her clothing and sat in protest. She has since been arrested by IRGC intelligence and taken to an unknown location.

Built a @turn_io maternal health demo. Here's the source application: gist.github.com/smn/082b557c… RAG doc. UI generates the code & vice versa. One can break out of the visual env or go hybrid when it stops being useful. #myelixirstatus is powering life improving conversations.

New Product Updates from Turn.io 🚀 At our recent Turn Town Hall, @smn Simon de Haan, Founder and CTO of Turn.io, shared exciting updates on #newfeatures launching soon. Here’s a quick snapshot of what you can expect: 1| New Staging Feature - This new feature allows you to test changes to your #userjourney in a controlled environment before a full release. It’s a great way to iterate and get feedback from a select group of testers, enhancing your ability to experiment safely. 2| AI Translations - We're giving your teams #languagesuperpowers using #AI! We are excited to launch bidirectional translation within the help desk. This automated two-way translation will enable teams to help people no matter what language they speak. 3| Integration with Meta’s LLaMA - Turn.io will soon support integration with @Meta's large language models, in addition to #OpenAI models. This feature allows teams to choose the model that fits their specific use case. 4| Multiple Assistants - We’re introducing the ability to create several assistants, each with unique roles and tasks so that you can deploy specialised #LLMs in different points of your journeys. This will enhance the efficiency and customisation for your user journeys. 5| Journeys API - This highly requested feature enables enterprise customers to automate their deployment processes fully. You can now push your journeys directly to Turn.io through a streamlined API. 6| Channels API - Another exciting addition coming soon, this feature allows services to extend beyond WhatsApp and launch on other platforms, such as Telegram or local messaging apps. It opens up new channels for reaching audiences who may not use WhatsApp, including #SMS and #USSD. #Turnio #ProductUpdates #AI #ChatForImpact #Innovation #TechForGood
