Join us in this exciting journey and help us shape the future of social interactions! ABOUT THIS ROLE We are looking for a Senior Marketing Manager to turn Yubo's brand ambition into brilliant, effective marketing, from major campaign moments to paid and owned-channel activity, and the smaller tests that help us learn what works. Reporting to the Director of Brand & Communications, you will translate Yubo's brand strategy into an executable US marketing programme. You will lead integrated brand campaigns, own campaign and paid-media planning and management, and build and manage influencer capabilities. This is a hands-on, high-ownership role for someone who can move comfortably between strategic thinking and execution. You will challenge plans constructively, make recommendations grounded in insight and data, and work closely with Creative, PR, Product, UA, Data, Trust & Safety and Legal to deliver marketing that builds the brand and drives growth. The role will focus on the US first, with scope to contribute to expansion into new markets as Yubo's marketing activity grows. This is a freelance position on a 6-month contract, with a target start of Q4 2026. YOUR RESPONSIBILITES Turn strategic priorities into impactful marketing activity • Lead the development and execution of Yubo's priority brand campaigns in the US, from insight and strategy through briefing, delivery, optimisation and reporting. • Translate Yubo's positioning, audience priorities and seasonal moments into cultural marketing activity that earns attention amongst Gen Z. • Develop integrated channel plans across paid, earned and owned activity, working closely with PR and Creative to ensure every channel plays a clear role. • Own campaign budget planning and day-to-day management, partnering closely with UA on paid-media strategy and optimisation. • Explore new, less traditional ways for Yubo to reach and engage people, challenging default channel choices and designing approaches that make marketing work harder. Establish brand marketing operations and measurement • Establish effective working rhythms across Brand, Creative, PR, Product, UA and Data, from briefing and approvals to reporting and learning. • Work closely with Data and UA to analyse performance and make clear, evidence-based optimisation recommendations. • Build clear measurement plans so every campaign, test and experiment informs future investment and potential expansion into new markets. • Identify, recommend and deliver smaller tests and experiments that help Yubo learn quickly and improve future investment. Build influencer, social and community activity • Build the plans, operating models and internal capability needed to deliver consistently strong influencer activity and integrate it into wider campaign plans. • Manage influencer agency relationships, negotiating cost-effective partnership models that maximise impact and effectiveness. WHO YOU ARE You are an experienced brand marketer with strong consumer instincts and a genuine interest in youth culture. You know how to turn a positioning and a business objective into a campaign people notice, and how to turn campaign results into smarter decisions next time. You are as comfortable building a strategic recommendation as you are writing a brief, reviewing creative, shaping a media plan, interrogating performance data or getting into the practical detail needed to make work happen. You don't wait for perfect information or a fully formed process; you create clarity, bring people together and move work forward. You will bring: • A breadth of experience in brand and integrated marketing, ideally in a high-growth tech, consumer app, entertainment, lifestyle or youth-culture business. • A track record of developing and delivering integrated campaigns across paid, owned and earned channels, working closely with cross-functional …

Join us in this exciting journey and help us shape the future of social interactions! ABOUT THIS ROLE As Yubo continues to scale, Machine Learning is becoming a core production layer, powering critical systems across safety, recommendations, and product optimization. What makes this role unique is both the scale and diversity of our data, and the level of maturity we are aiming to reach. We process massive volumes of images, text, and real-time user interactions, across millions of users worldwide, creating a wide range of high-impact ML challenges, including: • Content moderation (image, text, behavior) • Recommendation systems and user engagement optimization • Behavioral detection and trust & safety models • Emerging use cases such as dynamic pricing and growth optimization At the same time, our current ML stack is still evolving. Legacy models are not fully integrated into pipelines, lifecycle management remains inconsistent, and our approach can sometimes resemble “develop, deploy, and forget.” As ML usage expands across the company, this creates increasing complexity and dependency on reliable, well-structured systems. There is still a huge amount of untapped potential, with many ML use cases yet to be designed, tested, and scaled, but unlocking it requires building a more robust and scalable ML operating model. We are therefore looking for a Senior ML Engineer to join our Platform Engineering team, reporting directly to Mikael (Head of Platform Engineering). You will play a key role in delivering ML initiatives across the company, helping turn promising ideas into reliable production systems. You'll work on everything from model development and experimentation to deployment, monitoring, and continuous improvement, while contributing to the evolution of our ML platform and engineering practices YOUR RESPONSIBILITIES ML SYSTEMS & DELIVERY • Deliver end-to-end ML use cases (recommendation systems, safety algorithms, moderation models, etc.). • Design, train, evaluate, and deploy ML models where appropriate. • Balance speed of delivery with robustness and reliability. ML LIFECYCLE & RELIABILITY • Drive improvements across the ML lifecycle (training, deployment, monitoring, iteration). • Establish KPIs and monitoring standards to track model performance over time. • Ensure continuous alignment with product and safety objectives. • Help improve the reliability and observability of production ML systems. PLATFORM & STANDARDIZATION • Contribute to the evolution of our ML platform through tools, workflows, and reusable components. • Help establish and promote scalable ML engineering practices across teams. • Contribute to improving self-service ML capabilities where relevant. LEGACY & ADVANCED USE CASES • Take ownership of legacy models and realign them with current business needs. • Improve, retrain, and integrate them into modern pipelines. • Contribute to best practices around LLM usage in moderation, recommendation, and other product domains. • Explore and implement advanced ML approaches where relevant. CROSS-FUNCTIONAL COLLABORATION • Partner with Data Engineering, MLOps, Backend Platform, and Product teams. • Act as a bridge between ML, platform, and business stakeholders. • Provide technical leadership on ML initiatives and help improve engineering practices across teams. • Share knowledge and help raise the overall ML maturity of the organization. OUR TECHNICAL ENVIRONMENT / ML SCOPE • ML frameworks: PyTorch • Languages: Python (data stack) • Core topics: Neural networks, LLMs, data sampling • Use cases: Recommendation systems, safety algorithms, moderation • Ecosystem: Data Engineering, MLOps pipelines, Backend Platform WHO YOU ARE • You have 5+ years of experience in ML / Data, including work on large-scale datasets (datasets of hundreds of gigabytes). • You have strong expertise in …
