Full-stack Software Engineer

About YouScan YouScan.io is one of the most successful Ukrainian SaaS companies. Our deep tech product, powered by in-house developed AI technology, is one of the leaders in the social listening space globally. The entire engineering department works on collecting billions of social media posts daily, processing them with cutting-edge technologies, and providing meaningful insights to our customers. We are a creative, low-ego, team-spirited company. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truthseeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code. We really value innovation, bottom-up ideas, and execution. We hold company-wide hackathons twice a year: We're in-person in a cozy office in central Kyiv with a beautiful terrace overlooking the historic center. About the role You'll join a small, self-contained squad building analytics products with and for some of the world's largest consumer brands. These products are greenfield builds with real users on the other side from day one. The brand partner sees what you ship, and the feedback loop is short, sometimes uncomfortably so. That's the appeal of the role, and it's also the bar. Responsibilities: Build and ship features on a new product, from the ground up Own your work end to end: UI, API, data model, tests, deployment, and whatever breaks at 6pm on a Thursday. Work directly with the project manager to turn a partner's vague ideas into a smooth user experience Pull, blend, and model data from multiple sources - our own social listening pipeline plus partner-supplied datasets that will never arrive in the shape you'd like. Contribute to technical decisions and help shape the product’s overall architecture. Keep an eye on performance, scalability, and maintainability as the product grows. What we're looking for Someone who is a strong engineer and, above all, a good teammate: shares their thinking early, communicates clearly, brings ideas, listens properly, and can hold a different view without making it a fight. You care about the product, not just the ticket. You're curious about how people actually use what you build. You're comfortable making a decision with incomplete information, asking the question nobody's asking, and taking something on without waiting to be assigned it. Must-haves: Experience 4+ years working in product-focused teams (especially SaaS) Node.js, C#, or Python as backend language. Solid frontend skills - you can build a clean, responsive interface yourself, not just wire up an API for someone else. Experience with data visualization is a real plus. Hands-on experience with large-scale data systems You take strong ownership of your tasks. Curiosity about UX and product design — not just how it works, but how it feels to users. Comfort with making architectural decisions and trade-offs. A collaborative mindset: you value teamwork, feedback, and knowledge sharing Proactive, self-starter approach Nice to have Exposure to marketing analytics, media measurement, or social data. Experience integrating LLMs into production features.
