At Similarweb, we are revolutionizing the way businesses interact with the digital world by revealing to them everything that happens online. Our unique data and solutions empower thousands of customers globally, including industry giants like Google, eBay, and Adidas, to make game-changing decisions that drive their digital strategies. In 2021, we went public on the New York Stock Exchange, and we continue to reach new heights! Come work alongside Similarwebbers across the globe who are bright, curious, practical, and good people. Why is this role so important at Similarweb? AI is changing how every team at Similarweb works - how we research, how we build, how we sell, and how we support our customers. Rather than have every team solve the same hard problems from scratch, we are building a single, company-wide AI platform that everyone builds on. As an AI Engineer on the AI Platform team, you will build that foundation: the agent runtime, the tool and data layer, the model gateway, and the evaluation and observability infrastructure that turn AI experiments into reliable production systems. Your users are Similarwebbers - engineers, analysts, data scientists, and business teams across the organization - and your work is what lets them ship agents and AI-powered workflows in days rather than quarters. This is a high-leverage, horizontal role. You will not be building one AI feature; you will be building the platform that dozens of AI use cases run on, and setting the standards for how AI is built and operated at Similarweb. So, what will you be doing all day? Design and build the core agent platform - runtime, orchestration, state and memory management, and a shared agent SDK that teams across the company use instead of rebuilding foundations. Build and operate the tool and connector layer, including MCP servers that expose Similarweb data, internal systems, and third-party services to agents in a consistent, safe way. Develop LLM-based agents for high-value internal workflows, and turn the reusable parts of each one back into platform capabilities. Implement integrations that let agents take automated actions on behalf of users, streamlining workflows and reducing manual overhead. Model gateway and governance. Establish secure-by-default patterns: permissioning and data-access boundaries, PII handling, prompt injection defenses, and audit logging, in line with Similarweb’s security and privacy standards. Continuously evaluate and improve the performance of AI models and agents to ensure high-quality, data driven results. This is the perfect job for someone who: 5+ years of experience in software engineering, with strong proficiency in Python. Hands-on experience with LangGraph, LangChain, or similar frameworks for building AI agents. Strong understanding of LLMs, prompt engineering, and AI agent architectures. Solid grounding in production engineering: REST APIs, asynchronous services, integrating external data sources, containers, and CI/CD. Strong collaboration and communication skills, including with non-engineering stakeholders across the business. Preferred Skills: Familiarity with the AI Agents ecosystem, including different LLM providers, vector store solutions, MCPs, and more. Experience with evaluating LLM performance and quality, and with LLM observability tooling LLMOps experience: cost and latency optimization, semantic caching, model routing, and capacity planning. Experience designing RAG systems over large or heterogeneous data sources. Awareness of AI-specific security and safety concerns, and how to mitigate them in a multi-tenant internal platform. Familiarity with cloud environments, especially AWS, and with Kubernetes and infrastructure-as-code. Why you’ll love being a Similarwebber: Impact : Work with the world’s leading digital intelligence platform and make a real difference. Innovation : Bring your ideas forward - we empower you to drive change. Hybrid work model : 3 days in our office and 2 days working from home . Our Office: Modern space in Prague’s DOCK IN area, stocked with snacks, drinks (we're big fans of kombucha), fruit and lunches on Tuedays. Benefits: 5 weeks of vacation, birthday day off, 3 sick days, or Multisport Top-tier Hardware : MacBook Pro M5, dual monitors, standing desks. Team Events : Regular team-building activities, monthly birthday celebrations with cakes and drinks, baking Thursdays and happy hours. Equity : Share in Similarweb’s success. Career Growth : Explore any path - leadership, switching teams, or upskilling through coaching and learning programs.

The Role As a Data Scientist on our Ad Intelligence team, you’ll build the models and algorithms that estimate how advertisers spend money and reach audiences across the web. This role demands a genuine understanding of the business logic behind our numbers, combined with the technical range to solve problems at any scale: sometimes the right answer is a carefully tuned heuristic shipped in a day, sometimes it’s a full ML pipeline that takes weeks to get right. Whichever approach is the right one, you will own the algorithm end-to-end. What You’ll Do Build a deep understanding of the business logic behind our metrics, and encode it into model assumptions, features, and validation rules. Design, build, and sometimes productionize models that estimate ad intelligence metrics. Apply modern ML techniques where they earn their complexity; and use simpler heuristics where they don’t. Own tasks end-to-end: from exploration and proof of concept through a full research cycle including careful model selection and evaluation. In some cases you will also create the production implementation in collaboration with engineers. Closely collaborate with data analysts to uncover and solve data quality issues. Document and communicate the assumptions and limitations behind each model, so stakeholders know exactly what the numbers do and don't capture. Use modern AI-assisted tooling (Claude, Cursor, and similar) as a core part of your daily workflow to move faster. The mindset that will help you succeed Analytical Thinking: Using analytical and statistical rigor to solve ambiguous problems and translate them into business value. Strategic Thinking : Weighing complexity against time available, and picking the modeling approach that best serves the timeline and the business need with respect to future sustainability and maintainability. Ownership: Taking a problem from raw data to a validated, production model without needing to be chased. Learning Agility: Comfortable picking up new tools, data sources, and techniques quickly, including AI-assisted development workflows. Collaboration : Working effectively with others within and across teams. What You’ll Bring MSc in Computer Science, Statistics, Mathematics, or a related quantitative field (preferred); strong practical experience can substitute a degree with knowledge in relevant fields (statistics, machine learning, advanced mathematics). 2-4 years of experience building and deploying machine learning models or statistical algorithms in production. Strong Python skills, and hands-on experience with modern ML algorithms. PySpark experience, or the ability and willingness to learn it quickly (with our support!). Our existing solutions run on Spark, and you’ll need to read, use, and build on that code effectively. Experience with big data in a cloud environment is an advantage; we use Databricks daily. Comfort using AI coding tools (Claude, Cursor, or similar) as part of your everyday workflow. A genuine drive to understand the business logic behind the numbers, not just optimize a metric in isolation. Pragmatism: the judgment to know when a simple heuristic beats a complex model, and the discipline to build the complex one when it’s actually needed. Why you’ll love being a Similarwebber: Impact 😎: Work with the most powerful digital intelligence platform in the world, loved by both customers and employees. Innovation 🚀: We value open dialogue and empower everyone to bring their ideas forward. You'll have the support and resources to take initiative and drive real change Our Office : Join us in our modern, newly designed office in the vibrant DOCK IN area (Prague 8).
