Alan

🤖 WHO WE ARE We’re building Mo — a health companion for everyone. We’re a small team within Alan, on a mission to redefine the future of care by democratizing access to medical expertise. We are building Mo, an intelligent, empathetic, multimodal LLM-based conversational AI assistant able to prescribe, triage, and proactively follow up on care. Imagine giving every person in the world instant, 24/7 access to personalised medical expertise - through chat, voice, or video. That’s what we are building 🤖. We kicked off the project in 2023, and we have launched Mo to all our french members (1M) in Q1 2026, making it the first safe AI health companion live at scale in Europe. 🚀 WHAT KEEPS US UP AT NIGHT We’re building a medical agent that works — reliably, safely, and at scale. You’ll work at the intersection of product engineering, ML engineering, and medical expertise. Our mission is to build the most accurate and reliable medical agent in the world, while delivering an outstanding conversational experience. Things we’re working on: * 💬 Deliver the most memorable chatting experience — You’ll work on making Mo the obvious choice when it comes to asking a health question. It means having a world-class snappy and delightful chatting experience, blazing fast time to answer, and rich content shared. * 🧱 Integrate Mo with Alan services and our healthcare system — You’ll work on integrating Mo with our other services (digital chat with HP, map of physical location of HPs, tailored prevention programs, …) to help members get from words to actions. * ➕ Extend our architecture to support the next chapters of Mo — You’ll work on our architecture, and agentic framework, to support Mo’s next needs (get more context, use new skills, be accessible in other countries we operate in) If you’re excited by the idea of building the future of healthcare, this is the team for you - we're at the start of the journey. If you’re curious, here is a paper we published recently. 🎯 IS IT YOU WE’RE LOOKING FOR? We’re looking for Product engineers with 3+ years of experience who get excited about building state-of-the-art AI systems and applying them to real-world, high-stakes problems in healthcare. * You’ll work at the frontier of LLMs, multi-agent architectures, and human-in-the-loop learning — and see your work deployed in production, helping real people. * You’ll implement new capabilities for Mo, working across engineering, data, and medical expertise * You'll have deep product ownership over the use cases supported in Mo, making sure we actually help our members get and stay better. * You’ll have significant influence on system architecture and code quality * You’ll mentor engineers, contribute to our product & engineering culture, and help build the team (including participating in hiring, shaping our interview loops, etc.). You would be a good fit in Mo if most of this sounds like you: * Applied background in software engineering and systems architecture * Experience with traditional ML, or LLMs, or ML dev ops is a big plus. * Product-minded: you want your solutions to be used, and impactful * Self-directed, pragmatic, driven, hard working * Humble and still willing to grow (no matter your seniority!) * Collaborative, enthusiastic about teamwork, learning, and teaching * Fluent in English (no need to speak French!) * Ex-founders are typically great fit in our team But above all, we are looking for high potential and curiosity: make sure to show us this when you apply! Everything else is a bonus. 🤘 HOW WE DO IT ? We benefit from Alan’s platform, infrastructure, distribution, and health expertise — but operate with the speed and focus of a startup.

Prelude

About Prelude Prelude is redefining how companies authenticate and onboard users - turning what's traditionally a cost center into a growth lever. Our flagship product lets businesses send OTP codes with the best price-to-conversion ratio on the market, dynamically selecting the most effective channel in real time (optimized SMS, WhatsApp, and more) while actively blocking spam and fraud that legacy providers miss. Founded in 2022 by former Zenly team members who lived the pain of broken SMS authentication firsthand, we're already serving fast-growing companies across Europe and are expanding into the US. But authentication is only the starting point - we're building the platform for trust at scale, with an ambitious roadmap of market-defining products ahead. Why join us Today, we're a team of 60 and growing, based in Paris, building products that power secure and high-performance user onboarding for companies across the world. We believe small, highly skilled teams outperform large, fragmented organizations, and we are intentional about staying focused on impact, quality, and speed. We operate with a flat org structure and value in-person collaboration, which helps ideas move faster, decisions stay grounded, and teams take full ownership of what they build. Our values * Care We care deeply about our customers, our teammates, and the quality and reliability of what we ship. * Bias for Action We move fast, test in the real world, and iterate quickly rather than over-optimizing in theory. * Ownership We take responsibility end to end, from identifying problems to delivering outcomes and learning from results. About the role We’re hiring our first dedicated Brand Marketer - there’s no playbook yet, and as the first hire in this position you'll be the one writing it! You’ll own how Prelude presents itself to the world - brand voice, social presence, content, events, PR - all of the work that turns curious developers and founders into customers. You'll also represent the company externally across different audiences. This is a hands-on role with a lot of autonomy, working directly with the founders and partnering closely with engineering, design, and sales. This position reports into our co-founder and CEO, Matias, and works closely with our Marketing Manager - who will own performance marketing and SEO. What will you do? * Frame our positioning and messaging, outlining Prelude's tone of voice and identity * Own Prelude's voice (including the Founders) across LinkedIn, X, Hacker News and other sites * Turn product launches, customer wins, and industry moments into on-brand posts (the more personality the better), owning our content calendar and shipping consistently * Run weekly experiments - posts, threads, replies, comments - and iterate based on what lands * Partner with design to develop the site, decks, ads, and swag * Pitch Prelude as a speaker to priority events as well as international media across business, but also newsletters and influencers. * Own our events strategy and organisation end to end: founder dinners, hackathons, developer conferences, tracking ROI and reporting on outcomes * Set goals with the founders and report on them weekly, bringing a commercial mindset to every channel decision * Use AI tools to scale output - editing agents, asset generation, and whatever else makes sense What are we looking for? * Experience in brand, growth, or content marketing - ideally from B2B SaaS but we’re open minded and happy to consider candidates from B2C or agency * Strong writing instincts across different formats - short-form social, long-form editorial, email, and event copy * Budget ownership and management * Confidence speaking publicly and building media relationships, representing Prelude externally * Experience planning and running events people actually remember * A genuine interest in developer-first products - you need to talk credibly to engineers and founders * Operator energy, getting things done without waiting for permission * Confidence using AI tools to increase your output * Knowledge of or enthusiasm to learn about security, authentication, or infrastructure * A portfolio that proves it (social accounts you’ve grown, events you’ve made memorable)
