You'll be the person who turns ambitious AI product ideas into production-ready features that global enterprises depend on. As Senior Full-Stack Developer, you build, scale, and optimize the platform that helps strategy and innovation teams make smarter decisions about the future.

This is a hybrid role based in Ghent (3 days in office), full-time, with deep experience in scalable B2B SaaS products.

What you'll do

• Build and scale core product features that directly shape how global customers interact with trends, signals, and AI insights.
• Plan, design, and deliver high-impact features in agile sprints, from idea to deployment (Python, Angular, Kubernetes, Elasticsearch, MongoDB).
• Implement high-quality, maintainable code with strict adherence to SDLC practices: code reviews, automated testing, feature flagging, CI/CD, security checks.
• Optimize performance across the stack: APIs, queries, pipelines, frontend rendering.
• Own deployments and operations in a controlled, cloud-native environment (Kubernetes, Canary releases, staging → production).
• Work closely with AI engineers and data engineers to integrate NLP pipelines, trend scoring, and LLM-powered features.
• Mentor junior engineers and elevate the engineering culture.

Who this role fits

• You already know your way around scalable B2B SaaS and feel at home building systems that need to perform at scale.
• You like solving hard problems and don't need handholding to figure out complex technical challenges.
• You enjoy working closely with AI engineers, product, and data teams instead of being "the developer at the end of the chain."
• You're comfortable with Python, Angular, MongoDB, Elasticsearch, Kubernetes, Git, RESTful APIs, CI/CD, and JavaScript/HTML/CSS.

Why join Trendtracker

• Work on an AI-first strategic intelligence platform used by teams at leading global organizations.
• Small, international team, plenty of ownership, and a product that is still evolving fast enough for your code to make a visible difference.
• You'll help build a category-defining product, not just "add features" to someone else's vision.
• One of the few Belgian tech companies building at a serious scale with proprietary AI/NLP capabilities.
