By integrating AI-driven cloud solutions with sustainable energy, we create scalable, intelligent ecosystems that drive efficiency, innovation, and long-term impact across industries. Guided by exceptional leaders and visionaries with decades

of expertise in finance, policy, technology, and innovation, we are committed to making long-term efforts to fulfil this vision through our technical innovation, client services, expertise, and capability expansion. 

Role Summary:  

We are seeking a creative and detail-oriented UI/UX Designer with expertise in Prompt and Context Engineering to help shape intuitive user experiences for AI-driven products. This hybrid role combines design thinking, user research, and interaction design with prompt and context engineering for large language models (LLMs) , ensuring that our AI interfaces are not only visually engaging but also contextually intelligent, reliable, and user-friendly. 

Key Responsibilities  

UI/UX Design  

• Lead the design of user flows, wireframes, and high-fidelity prototypes for AI-enabled applications. 
• Conduct user research, usability testing, and iterate designs based on insights. 
• Ensure accessibility, responsiveness, and consistency across all digital touchpoints. 
• Collaborate with product managers, engineers, and AI researchers to align design with functionality. 

Prompt & Context Engineering  

• Design, test, and optimize prompts for LLM-based workflows, ensuring high-quality and predictable outputs. 
• Develop context frameworks (system messages, grounding strategies, metadata injection, retrieval pipelines) to improve reliability and personalization of AI responses. 
• Collaborate with data science and engineering teams to implement and evaluate prompt templates , fine-tuned context flows , and AI-driven UX experiments . 
• Maintain documentation and best practices for prompt design, ensuring scalability across products. 

Key Requirements  

Education & Experience : 

• Bachelor’s degree in design, or related field. 
• 2+ years of experience in UI/UX design and at least 1+ year of AI/LLM prompt engineering experience preferred. 

Skills:  

• Strong portfolio showcasing UI/UX work (web, mobile, or AI interfaces). 
• Experience with Figma, Sketch, Adobe XD , or equivalent design tools. 
• Familiarity with prompt engineering, LLM APIs (OpenAI, Anthropic, etc.), and context-aware AI systems . 
• Understanding of information architecture, human-AI interaction, and usability heuristics .
• Bonus: Experience with retrieval-augmented generation (RAG) , embeddings, or conversational AI design. 

What You’ll Do  

• Design for impact → Create wireframes, flows, and polished prototypes that make AI tools feel effortless to use. 
• Engineer prompts & context → Write, test, and refine prompts, context frameworks, and templates that ensure LLMs deliver reliable and high-quality outputs. 
• Bridge UX & AI → Collaborate with engineers, researchers, and product teams to align user needs with AI behaviour. 
• Own the user journey → Run rapid user testing, gather feedback, and iterate at startup speed. 
• Experiment & innovate → Push boundaries on how design + AI can unlock new products, markets, and business models. 

What You Bring  

• A portfolio that shows taste in UI/UX across web or mobile apps. 
• Hands-on experience with Figma, Sketch, or equivalent . 
• Curiosity and skills in prompt engineering —you know how to get the best out of LLMs. 
• Understanding of human-AI interaction and how context shapes responses. 
• Bonus points if you’ve played with RAG, embeddings, or agentic workflows . 
• Strong problem-solving ability and a drive for innovation, and eagerness to learn emerging technologies and passion for building impactful solutions. 
• Startup DNA → bias to action, comfort with ambiguity, love for fast iteration, and flexible and growth mindset. 

Why Join Us  

• Shape a first-of-its-kind AI + clean energy platform . 
• Work with a small, mission-driven team obsessed with impact. 
• An aggressive growth path.
• A chance to leave your mark at the intersection of AI, design, and sustainability .
