How We Work

Tasks

• Develop and maintain our full-stack applications within the modern JavaScript/TypeScript ecosystem
• Design and implement scalable backend services using Node.js and Nest.js
• Build high-performance frontend solutions with React.js and Next.js
• Design and optimize relational databases (PostgreSQL, MySQL, MS SQL)
• Containerize and orchestrate services using Docker and Kubernetes
• Develop and integrate REST APIs
• Build and operate data pipelines, feature stores, and ML workflows for our agentic systems
• Develop, train, and evaluate machine learning models for marketing use cases (attribution, targeting, forecasting, anomaly detection)
• Implement Retrieval-Augmented Generation (RAG) pipelines (embeddings, vector stores, re-ranking)
• Set up and maintain LLM evaluation frameworks, prompt optimization workflows, and systematic quality benchmarks
• Apply code harnesses (especially Claude Code and Codex) throughout the daily development process — from planning and implementation to code review
• Collaborate closely with the founding team on the product architecture of agentic systems

Core Technical Competencies (Engineering)

• Several years of professional experience in full-stack development
• Strong knowledge of TypeScript and JavaScript
• Confident working with React.js, Next.js, Node.js, and Nest.js
• Experience with relational databases (PostgreSQL, MySQL, MS SQL)
• Hands-on experience with container technologies (Docker, Kubernetes)
• Familiarity with REST API design and Git workflows

Data Science & Machine Learning

• Solid Python skills, including common data/ML stacks (pandas, NumPy, scikit-learn, PyTorch, or TensorFlow)
• Experience across the end-to-end lifecycle of ML models: data preparation, feature engineering, training, validation, deployment, and monitoring
• Strong understanding of statistical fundamentals (hypothesis testing, regression, classification, time series)
• Experience with modern LLM workflows: prompt engineering, RAG, embeddings, vector databases (e.g. Pinecone, Weaviate, pgvector)
• Hands-on experience in model evaluation: metrics, benchmarks, A/B testing, and systematic evaluation frameworks
• Experience with notebook-based exploration environments (Jupyter, Colab) and transitioning them into production-ready pipelines
• Familiarity with MLOps tools (e.g. MLflow, Weights & Biases, DVC) is a plus

Code Harnesses

• Experience with Claude Code and/or Codex is highly appreciated — otherwise, a strong willingness to actively learn and adopt these tools

Personal Qualifications

• Excellent German (C2) and English skills (minimum C1)
• Genuine interest in generative AI and agentic systems
• Builder mentality: you deliver production-grade software, not just prototypes
• Analytical mindset: you make data-driven decisions and critically evaluate model behavior
• Nice to have
• A defining role in an AI-native startup with a strong enterprise focus
• Competitive salary and employee stock ownership plan (ESOP)
• Fully funded access to all relevant code harnesses, LLM APIs, and developer tools (Claude Max, Codex, GitHub Copilot, etc.)
• Compute budget for experiments, model training, and ML workloads
• Modern hardware setup (MacBook Pro of your choice)
• Flexible working hours and remote work options
• Office in Berlin and location in Dubai (DIFC AI Campus)
• A steep learning curve in Agentic AI, LLM orchestration, and AI-native engineering
