3RD is looking for an inventive and hands-on AI-Native Creative Technologist to bridge the gap between abstract AI capabilities and tangible client value. The role focuses on rapid prototyping, advanced prompt engineering, and building demos that show—not just tell—how brands will interact with the agentic internet.

Your responsibilities

Design advanced prompting strategies

• Design and test complex prompts that influence LLM outputs in live environments, moving beyond basic instructions to chain-of-thought and agentic workflows.

• Master the nuance of different models (Claude, GPT-4, Gemini) to understand how specific phrasing impacts brand voice, accuracy, and safety.

• Create "prompt architectures" that can be reused by internal teams to generate consistent, high-quality output for clients.

Build rapid prototypes and functional demos

• Use AI-native development tools (such as Lovable, v0, or Replit) to spin up functional front-end prototypes that demonstrate new search and discovery experiences.

• Translate abstract concepts—like "conversational interfaces" or "multimodal search"—into clickable, working demos for client presentations and internal R&D.

• Act as the technical bridge between design concepts and engineering reality, proving what is possible before full-scale development begins.

Drive multimodal R&D and experimentation

• Lead experiments combining text, voice, image, and video generation (using tools like Midjourney, Runway, and ElevenLabs) to enhance brand visibility in rich results.

• Identify how brands can show up in emerging "multimodal" AI answers, ensuring visual and audio assets are optimized for machine understanding.

• Stay on the bleeding edge of AI releases, testing new models immediately to determine their relevance for 3RD and our clients.

Translate technical possibility into business reality

• Collaborate with strategy and sales teams to create "art of the possible" demos that explain the future of brand interaction in AI-first interfaces.

• Demystify complex agentic behaviors for non-technical stakeholders, explaining not just how a prompt works, but why it drives value.

• Document successful experiments and prompt patterns so they can be integrated into the core 3RD methodology.

Who you are

• A hybrid creative/technical profile: you might be a developer with a design eye, or a designer who codes.

• Fluent in the modern AI stack—you don’t just use ChatGPT; you prototype with Lovable, generate assets with Midjourney, and automate with API connections.

• Curious about the "agentic internet" and prompt mastery as a form of new art direction.

• Comfortable working in a rapid, iterative environment where "perfect" is the enemy of "shipped."

• Able to explain complex technical prototypes in clear, simple language to people who are not specialists.

• Structured enough to document your experiments, ensuring that a "cool hack" can become a repeatable business process.

• Comfortable working in English.

What 3RD offers

• A central role in a growing, ambitious company shaping a new category in Europe.

• Access to the latest AI tools and the freedom to experiment with bleeding-edge technology as part of your daily work.

• A work environment that values clarity, focus, and calm, thoughtful execution—even when working with fast-moving tech.

• The chance to define how major brands interact with the next generation of the internet (Voice, Video, and Agents).

• Insight into the mechanics of visibility and credibility across systems like ChatGPT, Gemini, Copilot, and Perplexity.
