About the Role

There's a gap between a clever AI demo and a system the whole team actually runs on, and you're the one who closes it.

At Suspicious Antwerp, AI is already part of how we work, but it grew fast: tools connected to tools, data in too many places. We need someone who brings it all together into one unified database with a clear architecture, and keeps building on top of it.

Not the next vibe coder, but a full stack AI engineer. You use AI to build faster, but you understand every line that ships. You'll be the one with the deepest technical expertise in-house, which means real ownership, real impact, and the independence to do things properly.

What you'll be doing

Here's what the job looks like, and what you should already be able to do. If you recognise yourself in most of it, we want to talk.

Build internal tooling, from agents to dashboards

• You work with Git daily: branches, pull requests and resolving merge conflicts are routine
• You build a web app from zero to live yourself: frontend (e.g. React or Next.js), backend (e.g. Node or Python) and database

Bring our data together in one unified database

• You design a SQL database yourself (e.g. PostgreSQL): which tables, which relations, which indexes
• You write queries with joins and aggregations across orders, products and stock without breaking a sweat
• You've built a data pipeline that automatically fetches, cleans and stores data every day

Connect our e-commerce, support, logistics and advertising systems

• You've worked with APIs and webhooks, including rate limits, pagination and OAuth

Own hosting, deployment and security

• You set up a server yourself (e.g. AWS Lightsail or another VPS), install what's needed and put an app live
• You understand what Cloudflare does for you (DNS, SSL, caching, security) and can configure it

Build AI that runs in production, not just in a demo

• You've built an application that uses an LLM API (Claude, OpenAI or similar) and ran it in production
• You know when to prompt, when to use retrieval (RAG) and when fine-tuning is worth it
• You've built or connected an MCP server
• You know how to protect an AI application against prompt injection and keep customer data safe

Translate business needs into working solutions, and in time lead a small team of developers

What you bring

• Professional experience as a developer, including AI in a real application
• A degree in computer science, data science or engineering, or the ability to show you build at that level
• A feel for the Suspicious Antwerp brand
• You live in Belgium and work from our HQ in Antwerp
• Fluent Dutch and English

Nice to have, no dealbreaker

• Experience with e-commerce platforms such as Shopify
• Experience setting up evals to measure whether your AI gets better or worse
