UX/UI / Hybrid Developer / Designer

Title: UI/UX & Prompt/Context Engineering Designer  

Sustainability is a global organisation, pioneering the convergence of clean energy and AI, enabling profitable energy transitions while powering end-to-end AI infrastructure. By integrating AI-driven cloud solutions with sustainable energy, we create scalable, intelligent ecosystems that drive efficiency, innovation, and long-term impact across industries. 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. 

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. 

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. 

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. 

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. 

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. 

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 . 

· Startup DNA → bias to action, comfort with ambiguity, love for fast iteration, and flexible and growth mindset. 

Shape a first-of-its-kind AI + clean energy platform . 

· A chance to leave your mark at the intersection of AI, design, and sustainability .
