Vocalbeats.AI is a global technology company dedicated to AI innovation and audio experience. Introduced in 2022, the Vocalbeats brand was born from a bold mission: building the world's largest audio platform to better connect and communicate. 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.

• 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.
