AI Developer

Who we are
We’re GoSpooky: the ones who get all things social. A global agency made for the social era. We grow brands through content, community and commerce, keeping them at the forefront of culture. Social isn’t just first, it’s the foundation.

From creatives and commerce specialists to game designers and data analysts, we cover the full social spectrum. If it shapes internet culture, we’re on it, making fast, bold and relevant work that actually gets shared.

From TikToks that breaks the for you page, to creator stories built with real community insights, all the way to TikTok Shop, social affiliates and live social shopping that convert in real time.

As official partners of Instagram and Snapchat and partners and social affiliates of TikTok (Shop), we work with brands like KLM, JBL, Samsung, Prime Video and HEMA. Driven by bold ambition, endless creativity and authentic people, our teams think ahead, react fast and keep brands culturally relevant. Whether it’s live social shopping, creator management, social-first campaigns or turning a trend into a brand moment.

We’re always looking for fresh energy: people who bring new perspectives, challenge the norm and help us and our clients evolve. If you love shaking up social, thinking big and moving fast, you’ll fit right in.

The Role

As our Senior E2E AI Engineer, you are first and foremost experienced with dev work in production. You are not just prototyping in notebooks; you are architecting the end-to-end infrastructure, devops, and any necessary cloud or data engineering tasks that powers our next-generation AI tools.

Your mission is to build the "pipes and plumbing" that make AI agents reliable, observable, and secure. You will own the full stack: from Data Engineering on BigQuery, to API development with FastAPI, to Model Serving on Vertex AI, and finally to DevOps/CI/CD pipelines that keep it all running. You sit at the intersection of Data/Software Engineering and AIOps.

You will report to our AI Lead and work closely with the Data and Insights team and leaders across different business units.

This role is part-time (24 - 32 hours per week)

What you’ll do

• Develop and deploy complex AI workflows (advanced RAG, multi-agent systems) integrated with core productivity tools
• Build robust APIs and backends for RAG Pipelines and AI agents
• Design and maintain scalable data pipelines for ETL, ingestion, and data preparation to ground models in high-quality data
• Manage the testing deployment lifecycle, automating and versioning updates. Orchestrate models on Vertex AI (fine-tuning, serving, monitoring)
• Implement AIOps and Agent Observability (tracing, logging, monitoring), while enforcing security for model inputs, outputs, and infrastructure

What we’re looking for

• 6+ years of professional software/data engineering experience, including at least 2 years of production-level hands-on experience in AI development/engineering
• Proven experience with advanced RAG use cases, at least one major GenAI framework (e.g., LangChain, LlamaIndex, or Heystack) plus one multi-agent framework (e.g., Langgraph, Google ADK, Vertex AI Agent Builder, or Microsoft Agent Framework)
• Expert-level Python (or Typescript) skills. You write clean, modular, production-ready code. You are proficient with Pydantic (or an equivalent in Typescript) for validation and FastAPI for high-performance Async I/O
• Essential expertise in Google Cloud, BigQuery (complex SQL, data warehousing) and Vertex AI (deployment, serving). Strong capability in building ETL/ELT pipelines
• You are comfortable with Git, Docker, and Kubernetes. You are experienced in devops and know how to set up CI/CD pipelines to automate all the necessary testing and deployment. Practical knowledge of securing applications (API security, secrets management, IAM, input sanitization)
• Familiarity with MCP and A2A protocols. Hands-on experience with some LLMOps and AI evaluation framework (e.g. GenAI Evals on Vertex, DSPy, RAGAs) as well as high quality vector databases (e.g. Weaviate, Milvus, Qdrant, or Neo4j)

Nice to have

• Experience in creative studios or digital production
• Understanding of GDPR, data governance, and AI ethics
• Experience working with fine tuning SLMs and specialized vertical AI agents, n8n, and video generation models
• Experience with machine learning and neural networks

What’s in it for you?

• Flexible holiday policy for a proper recharge
• Commuting allowance
• Remote working possibilities in agreement with your team
• A MacBook for peak productivity
• Training opportunities to develop your skills and grow with us
• Healthy communal lunches to keep you fueled
• Fun events to connect, recharge, and bond as a team
• Phone allowance of up to €25/month (depending on your role)
• Unlimited mental health support via OpenUp
• A pension plan where you contribute a percentage of your salary
• Gift card and birthday wishes every year
• Dutch classes for international team members
