Headquartered in Singapore, we are committed to delivering high-quality mobile applications, with a strong focus on AI-driven solutions and audio-based experiences. Recognizing strong global demand, we have rapidly expanded from Singapore to international markets, offering products that resonate with millions worldwide.

What will your role:
Learn and deeply understand the core features, target users, and usage scenarios of multiple AI tools (e.g., writing, image, voice), and conduct prompt design and iterative tuning based on real-world workflows.
Translate product logic and users’ key tasks into well-structured prompt strategies; optimize prompt structure and content to improve response accuracy, usefulness, consistency, and controllability.
Evaluate prompt effectiveness through small-sample testing, metric monitoring, and user feedback; drive continuous iteration with measurable outcomes.
Collaborate closely with Product, ML/Algorithm, and Design teams to align prompts with product feature logic, ensuring quality and stability across critical user journeys.
Summarize reusable prompt patterns and best practices across scenarios; build an internal knowledge base to support fast expansion across the product portfolio.
Track advances in frontier LLM capabilities and compare outputs across different models (e.g., GPT, Claude, ERNIE Bot, Qwen); select or adapt the most suitable prompting approaches per model and scenario.
Gradually participate in explorations of model fine-tuning and application-layer optimization (e.g., RAG, SFT, LoRA), developing capabilities at the intersection of product understanding and model optimization.

What an ideal candidate means to us:
Bachelor’s degree or above in Computer Science, Artificial Intelligence, Electrical Engineering, Mathematics, Computational Linguistics, or related STEM fields.
Solid understanding of LLM fundamentals and limitations; hands-on experience with prompt engineering or a strong, demonstrated grasp of prompt design principles.
Strong product thinking: able to design and optimize prompts starting from user goals, product positioning, and real usage contexts.
Clear and structured communication with strong writing skills; able to precisely control output tone, format, and structure.
Familiar with basic data analysis tools (e.g., Excel, SQL, Python) and capable of quantifying and analyzing prompt performance.
English proficiency at CET-6 or above; strong reading and written communication skills to work with English technical documentation and debug English prompts.
High curiosity and learning agility; motivated to become an “AI application builder” who understands both business and models, and willing to go deep into product-facing scenarios to continuously improve LLM performance.
