• Supporting an AI development team in SecTechOps • Building and testing agents • Developing use cases for further investment and adoption

• Advanced Prompt Engineering: Designing complex, dynamic prompt templates with conditional logic and efficiently reusing information and context within prompts to maximize generation quality and reasoning. • Structured Outputs & Schemas: Implementing various response schemes (JSON mode, function calling, Zod/JSON schemas) to ensure AI outputs are predictable and ready for seamless integration into application logic. • Prompt Engineering & Evaluations: Building robust evaluation pipelines and using Langfuse to collect feedback and score the quality of responses in real time. • Tracing & Debugging: Performing deep debugging of complex LLM chains using Langfuse traces to identify bottlenecks and optimize for cost, latency, and context window usage. • AI A/B Testing: Running systematic experiments across different models via OpenRouter (e.g., comparing Claude 3.5 Sonnet vs. GPT-4o) and analyzing results based on quantitative metrics. • Data-Driven Decisions: Making deployment decisions for new prompts or models strictly based on quantitative benchmarks and trace data, rather than intuition. • Output Scoring & Analysis: Developing scoring systems to analyze the “Problem → Solution” chain and identify root causes of hallucinations or logic errors using Langfuse analytics. • Model Performance & Fine-Tuning: Regularly re-evaluating model performance as new architectures emerge and performing fine-tuning when necessary to meet specific domain requirements.

• Model Development – Design, train, fine-tune, and evaluate models spanning classical ML, deep learning (CNNs, transformers), and generative AI (LLMs, diffusion). • Data Exploration & Analytics – Conduct exploratory data analysis, statistical testing, and time-series / forecasting to inform features, prompts, and business KPIs. • End-to-End Pipelines – Build reproducible workflows for data ingestion, feature engineering / prompt stores, training, CI/CD, and automated monitoring. • LLM & Agentic AI Engineering – Craft prompts, retrieval-augmented generation (RAG) pipelines, and autonomous/assistive agents; fine-tune LLMs on domain-specific datasets to boost accuracy and align outputs with product requirements. • AI Automation & Integration – Expose AI components as micro-services and event-driven workflows; integrate with orchestration tools (Airflow, Prefect) and business APIs to automate decision pipelines. • Continuous Learning – Track advances in LLMs, vision, and analytics; share insights and best practices with the wider engineering team. • Mentor junior engineers and contribute to technical direction and engineering best practices.

Ready to spark your growth with us? 🚀 WHO WE LOOK FOR 🦄 We are looking for a Senior AI Engineer to join our Engineering team as a founding member of a new, high-impact venture. This is a "greenfield" role: you’ll be the first hire for a brand-new AI-powered application within our ecosystem, centered around conversational and agentic interfaces. You won't just be adding features; you'll be designing the system, making core architectural decisions, and reporting directly to the Engineering Director. As the team scales, you’ll play a central role in hiring, shaping the culture, and setting engineering standards from day one. If you are a builder who thrives in ambiguity and is excited to turn the latest AI advancements into a product used by millions, this role is for you! WHAT YOU WILL DO 🏄 - Lead the development of a new AI-powered product, from initial architecture to production-ready code. - Design and build sophisticated conversational experiences and agentic workflows that solve real shopper needs. - Own the full-stack lifecycle, ensuring seamless integration between LLM capabilities, backend logic, and frontend interfaces. - Set the bar for AI engineering standards, including RAG patterns, prompt engineering, and model orchestration. - Shape the future team by participating in hiring and mentoring as the project expands. - Collaborate directly with leadership to influence product strategy and technical roadmap. - Implement "AI-first" development workflows, leveraging tools like Claude Code to accelerate delivery. WHAT YOU WILL NEED 🪄 - Proven experience building AI-powered products (conversational UIs, agentic systems, or LLM applications). - Strong Full-Stack skills: you are comfortable owning the entire stack to get a product off the ground. - Deep AI/ML Tooling knowledge: expert-level familiarity with LLMs, RAG, agents, and orchestration frameworks (e.g., LangChain, CrewAI, etc.). - A Product Mindset: you care about user impact and business value, not just the elegance of the code. - Comfort with Ambiguity: you excel in greenfield environments where the path isn't always paved. - Growth Mindset: you seek feedback, learn loudly, and are eager to continuously improve. - Fluent in English: you’ll be working in a global, distributed environment. 👉 At our company, we value diversity and actively encourage it — we believe a variety of perspectives and backgrounds makes us stronger. We focus on potential rather than on having a “perfect” CV. If this role excites you and you believe you could grow into it — even if you don’t tick every single box in the requirements — we’d love to hear from you! NICE TO HAVE 🎆 - Experience with the AWS stack and serverless architectures. - DevOps skills: familiarity with deploying and monitoring AI applications at scale. - Prior experience in e-commerce or high-traffic consumer-facing products. - Experience in early-stage startups or "vanguard" teams within larger orgs. SALARY RANGE ⚖️ : €80,000 – €100,000 fixed gross salary per year. LOCATION 🌐 While we have offices all around the world, you can benefit from our flexible hybrid model, empowering you to work where you’re most effective in Europe. Full remote available. WHAT YOU WILL FIND AT SHOPFULLY 🤗 🌎 An opportunity to thrive in a rapidly scaling multinational company 🕶️ A vibrant, informal, and inclusive work environment 🧠 We champion autonomy, flexibility, and a hybrid work model, empowering you to own your work 📚 Access to learning opportunities and regular feedback sessions 🍓 Enjoy our central, modern offices featuring fresh snacks, coffee (including vegan options!), and ergonomic setups 🎉 Engage in meaningful team events: offsites, happy hours, company parties and celebrations that unite us beyond daily tasks 💻We provide all the necessary equipment for you to work effectively and set up your workspace, wherever you are 🧰 Benefit from additional country-specific advantages based on local contracts and practices WHO WE ARE 💜 We’re a team of 450 people (and counting!), from 30 different nationalities. We’re on a mission to innovate, and we believe the key to that is seeing the world through a variety of perspectives. That’s why building a more diverse team, as well as bringing in even more talent, is so important for us. TO FEEL AT HOME 🛋️ IN SHOPFULLY YOU NEED 🎯 - Progress Over Perfection: We move forward. Always. In a fast-moving world, speed with purpose beats certainty without action. Momentum matters—not for its own sake, but because it drives results. - Clarity Through Transparency: We bring each other along. We work in teams, not silos. Transparency gives context, and context enables action. That means we share decisions early, publish work in progress, and document outcomes so others can learn, move faster, and build better. - Learn Loudly: We grow by doing and by daring. Big bets unlock big breakthroughs. But real innovation demands risk, and risk always carries the possibility of failure. That’s not a flaw. It’s the price of ambition. - Challenge with Empathy: We speak up, even when it’s hard—because candor shows care, and leads to better outcomes. Listening deeply is how we grow. Disagreeing openly is how we build trust. Always Build Better: We are builders—of products, systems, and ideas. But more than that, we are builders of better. Better has no finish line.
