Founding Product Designer

Product Designer

Knowunity

TL;DR We’re looking for a world-class product designer who’s obsessed with craft & excited about AI. You’ll join +60 builders shipping one of Europe’s biggest consumer AI products, shaping how millions of students learn. WHY KNOWUNITY? We're building the #1 AI learning companion for 1 billion students. A future where every student on the planet can access, enjoy & benefit from the highest quality education. Since founding Knowunity straight out of high school in 2020, we've been committed to revolutionising how students learn. Millions of students already use our AI learning companion weekly. We just raised €27m - Europe’s largest education round in the past three years. The AI learning market is at an inflection point, finally enabling true personalisation at scale, and we're determined to build the first AI learning unicorn in this space. You will join an elite team of +60 hands-on builders serving 1 billion students worldwide. If we execute on our product vision, you will have built something generational that transforms education globally. This is your chance to build a generational company that shapes how an entire generation learns. WHY NOW? Design is the single highest-leverage investment at Knowunity right now. You’ll be at the center of that shift. We’ve built a product millions of students love, powered by an engineering team that ships & learns extraordinarily fast. Now we’re going all-in on craft. The kind of UI excellence, motion design, and systematic thinking that turns a loved product into a world-class one. We just brought on a new Head of Design. We’re building a design system from the ground up. And we’re working with Ragged Edge (the agency behind the Transferwise & Granola rebrands) on a major brand evolution. You won’t be maintaining someone else’s vision. You’ll be shaping it from the start. WHO YOU ARE Your portfolio matters more than your years of experience. Show us work that moved metrics & delighted users: * Craft-obsessed: The details are the design. You push back until the bar is raised. * AI enthusiast: From prototyping to research to shipping. You see AI tools as a multiplier, not a threat. * Systems thinker: You care about scaling quality across a product, not a pretty Figma library. Code-first design systems, AI-powered design reviews, whatever works at speed & scale. * Simplifier: Education is messy. AI is unpredictable. You turn complicated user journeys into experiences that feel obvious. * Biased to action: You move fast by default. Prototypes over presentations, experiments over endless debate. * Builder: You like getting your hands dirty. Bonus if you’ve shipped a side project end to end, or opened a merge request. * Team-first: Direct feedback, no preciousness, no territory. Engineers prototyping features? More builders means better outcomes. * Curious: New tools, new patterns, new ways of thinking. You stay up to date & experiment continuously because you want to, not because someone told you to. WHAT YOU'LL DO Raise the bar on everything students see, touch & feel. Make the Knowunity product undeniably world-class. * Set the standard: UIs students want to screenshot & details they feel, but can’t name. Your work is the reference point. * Scale it: Curated references, stellar components & sharp reviews. Make it easy even for vibe-coding PMs to hit the standard. * Pioneer AI-native design: AI changes how we research, ideate, ship, as well as what we ship. You’ll figure out both, from AI-assisted workflows to AI-native product experiences. * Idea to production, fast: Work directly with C-level & engineering. Concept on Monday, shipped on Wednesday, live for a million students on Thursday. WHAT WE OFFER Not for everyone. Everything for the right ones: * Impact at scale: Your work reaches millions of students daily. Future generations will know what you build. * Elite team, real ownership: +60 exceptional people. Direct access to C-level & founders. You own entire areas from conception to delivery. * Compensation & equity: Competitive salary paired with meaningful equity in a company with genuine unicorn potential. * Benefits: 28 days annual leave, 40 days work from anywhere, personal development budget, mental health support, Urban Sports Club, monthly retail vouchers, team & company events. NEXT STEPS Click “Apply for this job” and submit your CV and LinkedIn profile. We move fast. 1. Intro call: Get to know each other, see if there’s mutual excitement. 2. 5 minute Loom: walk us through something you’re proud of. A feature you shipped, an app you vibe-coded. Your pick. 3. Deep-dive call: Unpack your Loom case with our head of design/CPO, discuss your experience & perspective. 4. On-site day: Meet our CEO, CPO & the team. Work together, get a real feel for the culture. We’ll cover travel. We encourage applications from exceptional talent regardless of traditional background requirements. Knowunity is an equal opportunity employer committed to diversity and inclusion. We welcome applications from all qualified candidates regardless of nationality, ethnic origin, religion, gender identity, sexual orientation, disability, or marital status.

Founding Design Engineer

telli

ABOUT US Every 10 minutes, 18 million conversations happen between businesses and consumers around the world. For decades, the consumer side of those conversations sucked: long queues, robotic menus, repeated explanations, and advice that is often unhelpful. Most people today still cannot simply say what their problem is in natural language when communicating with businesses. AI changes that. For the first time, companies can have natural conversations with customers at massive scale. Every B2C company - from energy providers to telcos to insurers - will use AI agents to talk to their customers. The number of conversations businesses will handle is going to explode in the coming years. At telli, we are solving the challenges that come with that shift. Today, leading B2C companies like Sky are already using telli to deploy thousands of voice agents to provide their customers with a new experience. But building a first voice agent is easy, getting it to drive real outcomes for customers and businesses is the hard part. telli helps companies build, deploy, and improve consumer-facing AI voice agents at scale. This will become one of the most important software categories of the next decade, and we intend to win it. We are a small, AI-pilled team that likes to solve hard problems. Be it engineering, product, or GTM - we build, experiment, and move fast, while heavily leveraging the capabilities of AI models. All of us like to challenge ourselves and take real ownership over what we do, all while still staying humble and keeping a low-ego culture. Check out our principles to see how we work. ABOUT THE ROLE This is a role for people with great taste in designing software & AI systems. You will own design across the company and find novel UX patterns to solve problems that haven’t existed in software products before. We are pushing the limits of LLMs and looking for someone to build the future with us. Things that you might work on: * designing UX patterns that work both for web applications and within chat (ChatGPT, Claude, Codex, etc.) * agentic loops that let customers analyze and improve their voice agents * define and implement design language of our product & brand WHAT WE LOOK FOR we believe that the role of a product designer and engineer are merging. We are looking for someone who wants to shape that shift with us. If you are designer who has never written production code, that is ok - as long as you are willing to experiment and learn. * Aesthetic taste - can you craft visually appealing products * Functional - you can craft products that solve real problems * Unassuming - you don’t work on assumptions but build a mental model from real customer insights & conversations * High Ownership - Nobody has to tell you what to do, you just do things * First Principles Thinking - You don’t take what people say at face value. You make sure you understand the underlying problem * AI-pilled - You are heavily leveraging AI in your work * Strive in ambiguity - You are able to jump into novel ambiguous problem, understand the reason and solve it * Builder - You love to create things. Bonus if you also create things in code The most important signal for us is your portfolio and the things you have built. We don’t care too much about years of experience or what companies you worked at. More the things you created. WHAT MAY NOT MAKE YOU A GOOD FIT * you prefer a remote-first environment * you want to be told exactly what to do * you mostly care about the tech, not business outcomes * you want to work 9-5 PERKS * very competitive pay + equity package * access to any (AI) tools * free dinners if you stay late * urban sports * relocation support if you don’t live in Berlin

AI First Builder (Product Management) (d/f/m)

Taxfix

OUR STORY: Every year millions of people are either filing their taxes in fear or giving up on their tax refund altogether. We're working on fixing that. Our intuitive app enables anyone, regardless of education or background, to file their taxes with newfound confidence. Spread across Germany, Spain and the UK, the team at Taxfix Group with its brands Taxfix, Steuerbot and TaxScouts, is a compassionate group of solution-finders. We speak our minds openly, and with over 400 professionals, including tax experts, developers, and IT security experts, we're rich in ideas and voices. The group has facilitated more than 3.5 billion euros in tax refunds for its customers since its founding in 2016.   YOUR OPPORTUNITY: AI is shifting how the best products get built. The handoffs between product, design, and engineering are slowing us down. The companies moving fastest are doing it with people who own the full loop, from the user problem to the shipped feature, without losing the thread. At Taxfix, we’re rebuilding our R&D organization around this idea. We call these people builders. A Builder has a primary craft, one they’re genuinely excellent at, but they don’t stop there. They stretch across product, design, and engineering as the situation demands, using AI to cover the gaps. They’re accountable to outcomes, not job descriptions. Taxfix has put €5 billion back into our customers’ pockets and we aren’t stopping there. We operate in Germany, Spain, and the UK, and we’re in the middle of a genuine AI transformation in how we build and how we’re organized. Assume there’s no designer to give you a Figma file. No engineer to hand the spec to. The magic is knowing what to build, why, and in what order, then making it happen. If building the thing sounds more natural to you than describing it, this role is for you.   YOUR RESPONSIBILITIES AND DECISIONS: * Take a user problem from rough idea to shipped product. Write the brief, design the flow, prototype it, and get it in front of users, with as few handoffs as possible. Own the full loop. * Compress research, synthesis, and spec-writing from weeks into hours. You reach for AI tools not because you’ve been asked to, but because they’re faster. You know when to trust the output, when to edit it, and when to reject it. Use AI as a force multiplier. * You structure fuzzy problems, identify what should and shouldn’t be built, and move forward when there are dozens of possible directions. The magic is in the trade-offs, not the feature list. Turn ambiguous ideas into things users can trust. * No layers, no waiting. You’ll work closely with two or three other people who share the same model. Work in small, focused teams. * You know the metric your team is trying to move. You measure your week by what changed in user behaviour, not by how many tickets moved to Done. Be accountable to outcomes, not roadmaps. * You give feedback directly, to anyone, regardless of level. You raise blockers early and in the open. Push back when something’s wrong. Team player who raises the bar. * The PM who builds the prototype instead of describing it. Who writes the SQL query instead of waiting for an analyst. Who reads the API spec before assuming something is impossible. Who writes code to get it into the hands of users faster. That instinct is what we’re hiring for. Stretch beyond product.   YOUR PROFILE: YOUR CRAFT * You have a genuine product craft and a track record to prove it. You’ve shipped things that real people use, and you can point to the metric that moved when you did. * You have a builder track record: you’ve made things with AI, not just written specs about them. Shipped products, agent workflows, or tools real users have touched. Any of these count. * You’re AI-native by default. You use tools like Claude, Cursor, Lovable, or similar regularly. You follow the AI product space closely and you know the difference between a demo and something production-ready. * You’ve built personal AI workflows that make you meaningfully faster. You know when to trust AI output, when to edit it, and when to reject it. * You’ve gone from user problem to testable prototype without waiting for a brief to be written for you. The output was good enough that a team shipped from it. * Low PM baggage: you’re not attached to how product management "should" be done. You care about outcomes, not territory. YOUR RANGE * Across all three disciplines, you can hold your own: in Product you can identify opportunities, assess impact, and prioritize ruthlessly. In Design, you have taste: you know when something looks right but feels wrong. In Engineering, you’ve used AI coding tools to build something real, and you’re not dependent on an engineer to tell you why it’s broken. HOW YOU WORK * Data fluency: you know the metric you were trying to move, and you can say whether you moved it, with healthy skepticism about what metrics do and don’t tell you. * You believe in experimentation and ship with velocity to learn quickly. You know your way around AB tests and are excited to try new data science models to learn faster. * You’ve worked on products where getting it wrong has real consequences for real people, and that raised your bar, not lowered it. * You’ve found a way through blockers rather than waiting to be unblocked. When something was genuinely impossible, you documented why and moved on. * Fluency in English is required. THIS ROLE IS NOT FOR YOU IF… * You’re not genuinely excited about being able to stretch across design and engineering functions. * You’ve never built an AI prototype and/or shipped code (vibe coded side project counts) * You pride yourself in what you delivered rather than the outcome you achieved. * You need certainty, a full brief, or someone else’s research to get started. * You don’t believe in fast learning and getting things into customers hands early and use   WHY TAXFIX? * A chance to do meaningful, people-centric work with an international team of passionate professionals. * Holistic well-being with free mental health coaching sessions and yoga. * A monthly allowance to spend on an extensive range of services that you can use and roll over as flexibly as you like. * Employee stock options for all employees—because everyone deserves to benefit from the success they help to create. * 30 annual vacation days and flexible working hours. * Work from abroad for up to six weeks every year. Just align with your team, and then enjoy your trip. * Plenty of opportunities to socialise as a team. In addition to internal tech meetups, our international team hosts regular get-togethers—virtually and in person when possible. * Free tax declaration filing, of course, through the Taxfix app—and internal support for all personal tax-related questions. * Have a four-legged friend in your life? We’re happy to have dogs join us in the office. Excited? So are we.

We're proudly committed to equal employment and development opportunities no matter your gender, race, religion, age, sexual orientation, colour, disability, or place of origin.
