Lead AI Native Full-Stack Developer

About Wunderdog We're a 70-person consultancy helping development teams get better at using AI tools to build things the right way and faster. Not through Powerpoint slides, but through handson training workshops and actual work in teams at companies like Finnair, Elisa, SOK, Alma Media, Sanoma, Blueprint Genetics, RELEX, Smartly and Babbel. Our focus is the development team and nothing else. We care about making teams better more than anyone else.

Lead AI Native Full-Stack Developer As a Lead AI Native Full-Stack Developer, you will pioneer the integration of generative AI into real-world applications, guiding customers from early experimentation to production-ready systems that deliver measurable value.

What You Will Do

• Design and build AI-powered solutions end to end: from prototypes to production services and, ideally, the frontends and tools around them.
• Work with modern GenAI techniques (LLMs, RAG, agents, tool-use, evaluation / guardrails) and integrate them into existing systems and workflows.
• Lead technical discovery and architecture discussions with customers, turning fuzzy problems into clear, actionable roadmaps.
• Coach client organisations in adopting agentic development practices, with harness engineering as one part of the toolkit
• Own delivery: orchestrate agents to produce clean, testable code, design scalable cloud architectures, and make sure what we build can be operated in the real world, with the engineer accountable for every line that ships.
• Act as an AI advisor: run workshops, pair with customer teams, and help them reskill and adopt AI sustainably instead of just shipping PoCs.
• Contribute to our wider community: share learnings with colleagues, and when possible, speak, write or demo in public forums.

Consulting for us means shipping and helping teams get the ball rolling when they're stuck. You propose solutions, and prove with agentic harness that your solutions work. You will be working as part of our client teams and can also lead Wunderdog's entry into new clients. You build trust through your work. You speak fluent Finnish and English.
