• 精通提示工程与数据集构建，能确保内容与语气、安全性、可信度一致

• 熟悉各类评估指标，如困惑度、毒性、相关性

• 具备良好的软件工程基础，包括算法、数据结构和规范代码实践

加分项

• 有文本生成、内容审核或个性化推荐的相关经验

• 有使用 RLHF（人类反馈强化学习）或 LLM 强化学习经验

• 有参与开源机器学习项目的经历

你将获得

• 扁平化结构与真正的项目所有权

• 全面参与产品方向与共识式决策

• 灵活的办公方式

• 高影响力岗位，覆盖产品、数据与工程团队

• 市场顶尖的薪酬方案与绩效奖金

• 全球化产品开发视野

• 丰厚福利 —— 住房租赁补贴、高质量公司餐厅、加班餐补

• 健康、牙科与视力保险

• 全球旅行保险（适用于你和家属）

• 无限制、灵活的休假制度

团队与文化

我们是一支高密度、高绩效的团队，专注于高质量成果与全球影响。我们像主人一样思考与行动，重视速度、清晰与持续的责任感。如果你渴望成长、追求卓越，我们欢迎你加入。

Transform Language Models into Real-World Applications

We’re building AI systems for a global audience. We are living in an era of AI transition - this new project team will be focusing on building applications to enable more real world impact and highest usage for the world.

This role is a global role with hybrid work arrangement - combining flexible remote work with in-office collaboration at our HQ. You’ll work closely with regional teams across product, engineering, operations, infrastructure and data to build and scale impactful AI solutions.

Why This Role Matters

You’ll fine-tune state-of-the-art models, design evaluation frameworks, and bring AI features into production. Your work ensures our models are not only intelligent, but also safe, trustworthy, and impactful at scale.

What You’ll Do

• Fine-tune & adapt - Use LoRA/QLoRA to optimize open-source models (LLaMA, Mistral, Gemma)

• Engineer prompts & curates data - Craft prompts and datasets that reflect tone, brand voice, and safety.

• Evaluate models – Build metrics pipelines for perplexity, toxicity, and relevance to ensure safe and high-quality outputs.

• Deploy & monitor – Scale models into production with performance optimization and monitoring for drift.

• Collaborate & deliver – Partner with product, engineering, and design teams to launch user-facing AI features.

What Is It Like

• Likes ownership and independence

• Believe clarity comes from action - prototype, test, and iterate without waiting for perfect plans.

• Stay calm and effective in startup chaos - shifting priorities and building from zero doesn’t faze you.

• Bias for speed - you believe it’s better to deliver something valuable now than a perfect version much later.

• See feedback and failure as part of growth - you’re here to level up.

• Possess humility, hunger, and hustle, and lift others up as you go.

Requirements

• Strong experience in transformers, deep learning, and fine-tuning methods (LoRA/QLoRA, SFT, distillation).

• Proficiency with PyTorch (preferred) or TensorFlow.

• Skilled in prompt engineering and dataset curation for alignment with tone, safety, and trust.

• Familiar with evaluation metrics: perplexity, toxicity, relevance.

• Strong software engineering foundations in algorithms, data structures, and clean code practices.

Nice to Have

• Prior work in text generation, moderation, or personalization.

• Experience with RLHF or reinforcement learning in LLMs.

• Contributions to open-source ML projects.

What You’ll Get

• Flat structure & real ownership

• Full involvement in direction and consensus decision making

• Flexibility in work arrangement

• High-impact role with visibility across product, data, and engineering

• Top-of-market compensation and performance-based bonuses

• Global exposure to product development

• Lots of perks - housing rental subsidies, a quality company cafeteria, and overtime meals

• Health, dental & vision insurance

• Global travel insurance (for you & your dependents)

• Unlimited, flexible time off

Our Team & Culture

We’re a densed, high-performance team focused on high quality work and global impact. We behave like owners. We value speed, clarity, and relentless ownership. If you’re hungry to grow and care deeply about excellence, join us.
