Job Brief (Full-Time)

We are looking for a versatile professional to bridge AI innovation with client engagement. This dual-role combines presales activities—understanding customer challenges, developing proposals, and showcasing AI capabilities—with the technical expertise to drive prototyping of AI-driven solutions with a high performance AI team.

The ideal candidate must be technically competent while equally comfortable presenting to senior business stakeholders and building hands-on prototypes with modern AI frameworks. This is a strategic role that directly influences client adoption while shaping the early design of scalable AI solutions.

Responsibilities

Presales & Client Engagement

• Engage with potential clients to uncover pain points and translate them into AI use cases.
• Lead discovery sessions and solution workshops with internal and external stakeholders.
• Develop proposals, pitch decks, and demos that highlight business value through Generative AI.
• Build and maintain strong client relationships, serving as a trusted advisor on AI opportunities.

AI Prototyping & Exploration

· Solution Design & Ideation: Translate client problem statements into technical hypotheses and conceptual AI architectures. Identify opportunities for applying LLMs, RAG pipelines, and multi-agent frameworks to specific business needs.

· Rapid Prototyping: Be able to work with AI team to build proof-of-concepts and demos using state-of-the-art external (e.g., LangChain, LlamaIndex, Hugging Face, vector databases) and in house frameworks. Showcase functionality quickly to validate business value and feasibility.

· Experimentation & Benchmarking: Evaluate different LLMs (GPT, Claude, Llama, Mistral, etc.) and architectures for accuracy, latency, scalability, and cost efficiency. Conduct A/B testing and fine-tuning to optimize results.

· Data Handling & Integration: Design lightweight data pipelines for ingestion, preprocessing, and embedding generation. Work with structured and unstructured data sources to enable retrieval-augmented generation (RAG) and knowledge mining.

· Workflow Engineering: Develop agentic workflows that combine reasoning, retrieval, and tool usage. Prototype orchestration layers for decision-making tasks, simulations, or automation of multi-step processes.

· Evaluation & Governance: Define metrics and perform validation on prototype outputs for reliability, robustness, and alignment with responsible AI practices (bias, explainability, transparency).

· Documentation & Knowledge Transfer: Capture design decisions, experiment results, and prototype architecture. Provide clear technical documentation for internal stakeholders and delivery teams.

· Transition to Delivery: Collaborate with engineering and product teams to convert successful prototypes into scalable solutions ready for production deployment. Provide presales technical handover to ensure client expectations are met.

Requirements

· Bachelor's or Master's in Computer Science, AI, Data Science, Business, or related fields.

· Strong technical grounding in LLMs, NLP, and Generative AI. Experience with RAG, agentic workflows, and open-source AI frameworks preferred.

· Proven experience in client-facing roles such as presales, solution consulting, or technical evangelism.

· Excellent communication and presentation skills, capable of translating complex AI concepts into business value propositions.

· Proficiency in Python and modern AI prototyping tools (LangChain, Hugging Face, vector databases such as FAISS/Chroma/Weaviate).

· Familiarity with Agile project methodologies and project tracking tools (e.g., Jira, Confluence).

· Exposure to cloud AI platforms (AWS, Azure, GCP) and containerization technologies (Docker, Kubernetes) is a plus.

· Certifications in AI, ML, or project management (e.g., AWS ML Specialty, TensorFlow Developer, PMP) are an advantage.

What we offer

· Opportunity to work on cutting-edge generative AI projects that directly impact business innovation.

· Join a young and dynamic team with forward-looking working culture that fosters innovation, collaboration, and personal growth.

· Access to cutting-edge technology resources, opportunities for continuous learning and skill development.
