Visionary AI & Automation Developer

ABOUT YONDERLAND  

We are convinced that outside is exciting, relaxing, and inspiring. It’s versatile, for some it is a place to relax, for others it is the ultimate challenge. A place to enjoy and where big and small moments come together. It’s a place to be discovered or recognized. But the outdoors can also be treacherous and unpredictable. Weather and terrain can surprise you. Our mission is to enable all people to spend inspiring and epic moments outside.  

Yonderland is a European group of premium brands and retail concepts focused on outdoors. Including A.S. Adventure, Juttu, Bever, Cotswold, Snow+Rock, Runnersneed and Ayacucho. Yonderland runs over 190 shops in Belgium, Luxembourg, France, Great-Britain and The Netherlands and resides in Belgium. https://www.yonderland.com/ 

ABOUT THE JOB OPENING  

WE ARE LOOKING FOR A VISIONARY AI & AUTOMATION DEVELOPER TO JOIN OUR TEAM 

We are looking for an experienced Senior AI Developer to join and help lead our AI and Automation team. You'll guide the exploration of what's possible with LLMs, agents, and emerging AI capabilities, while mentoring others and setting technical direction. This role is perfect for someone who has been deep in the AI space, loves pushing boundaries, and wants to share their expertise while continuing to learn in this rapidly evolving landscape.

YOU WILL

• Lead the exploration and evaluation of cutting-edge LLM platforms, agent frameworks, and AI tools
• Design and architect AI-driven solutions that scale from proof-of-concept to production
• Mentor mid-level and junior developers, sharing your knowledge and fostering a culture of experimentation
• Collaborate with leadership to identify strategic opportunities where AI can transform workflows and business processes
• Build sophisticated prototypes and production systems that demonstrate the art of the possible
• Stay ahead of the curve on emerging AI technologies and guide the team on what's worth adopting
• Participate in (and sometimes lead) technical design discussions
• Bridge the gap between experimental AI capabilities and practical business value
• Contribute to the team's technical roadmap and strategic vision for AI and automation

YOU HAVE

• 5+ years of development experience with at least 2+ years deeply focused on AI/LLM applications
• Proven programming skills in Python and experience with multiple technology stacks
• Proven track record of building production AI systems or substantial personal projects that showcase advanced AI capabilities
• Deep hands-on experience with LLMs, agent frameworks, and the broader AI ecosystem
• Has not just played with agents and LLMs, but has built complex systems with them and understands their limitations
• Understands the nuances of prompt engineering, context management, reliability patterns, and when AI is (and isn't) the right solution
• Experience mentoring or leading other developers
• Strong system design skills and ability to architect solutions that balance innovation with pragmatism
• Excellent at explaining complex technical concepts to both technical and non-technical audiences
• Thrives in fast-paced environments where the technology landscape shifts rapidly
• Track record of turning experimental ideas into real-world impact

It will be nice to have

• Deep understanding of transformer architectures, embeddings, vector databases, and RAG systems
• Experience with MLOps, monitoring AI systems in production, and managing AI-related costs
• You've built multi-agent systems or complex agentic workflows
• Experience with AI safety considerations: prompt injection, output validation, reliability engineering
• Background in machine learning, NLP, or related fields (formal education or self-taught)
• Experience leading technical initiatives or projects from conception to delivery

WHAT MAKES YOU EXCITED

• Discovering novel approaches to problems that seemed unsolvable months ago
• Seeing a new AI capability and immediately prototyping three different applications for it
• Helping a teammate have their "aha!" moment about how to use AI effectively
• Debating the trade-offs between different architectural approaches with the team
• Building something that fundamentally changes how work gets done
• The challenge of making unreliable AI systems reliable enough for production
• Staying at the bleeding edge of a field that's evolving faster than any in recent history
• Creating leverage by sharing knowledge and elevating the entire team's capabilities

ABOUT THE AI AND AUTOMATION TEAM

You'll be joining a team dedicated to exploring how AI can transform the way we work. As a senior member, you'll help shape:

• The technical vision and roadmap for AI-driven automation solutions
• Engineering standards and best practices for AI development
• A culture of curiosity, rigor, and continuous learning
• How we balance innovation with reliability and production-readiness
• The growth and development of other team members
• Our approach to staying current in an incredibly fast-moving field

We believe the best senior AI developers are those who combine deep technical expertise with genuine curiosity and a passion for sharing knowledge. If you've been building sophisticated AI systems, have strong opinions (loosely held) about what works, and are excited about leading a team that's pushing the boundaries of AI and automation, we'd love to talk.

WE HAVE  

• An office at Lionesa Business Hub   
• Full-time job + without term contract  
• Health insurance  
• 26 days of vacations  
• Flexible work schedule and hybrid work model - 3 days at the office & 2 days remote
