Machine Learning Engineer II, Responsible AI
Pinterest简介：
全球数百万人来到我们的平台，寻找创意灵感，畅想新的可能性，并规划将伴随一生的回忆。在Pinterest，我们致力于为每个人带来创造理想生活的灵感，而这一切始于产品背后的每一个人。
在这里开启职业生涯，你将点燃创新，把热情转化为成长机会，庆祝彼此的独特经历，并拥抱灵活的工作方式，发挥最佳水平。打造你热爱的职业？这完全可能。
在Pinterest，AI不只是一个功能，而是增强我们创造力、放大我们影响力的强大伙伴，我们正在寻找对参与这一进程充满热情的候选人。为了全面了解你的经验和能力，我们将考察你的基础技能以及与AI协作的方式。
在我们的面试过程中，最重要的是你能清晰地解释你的思路，不仅展示你掌握的知识，更体现你的思维方式。你可以在此了解更多关于我们的AI面试理念以及我们在招聘过程中如何使用AI的信息。
负责任的AI团队是高级技术组（ATG）的一部分，ATG是Pinterest的先进机器学习团队。ATG的目标是让Pinterest在多个应用场景中的机器学习技术保持领先地位，包括推荐、排序、内容理解等。这是一个应用型团队，横跨公司各业务线开展最前沿的AI和ML工作，并与产品工程团队合作，直接将这些技术应用于产品中。该团队也会在应用研究会议上发表研究成果，但团队的主要目标是直接影响业务指标。
在Pinterest，我们的目标是激发用户（即“Pinners”）的生活热情，让他们过上自己喜爱的生活。产品由最先进的机器学习算法驱动，用于理解平台上数十亿张视觉丰富的物品以及5.35亿月活跃用户的需求，从而向他们推荐富有启发性的个性化内容。这意味着Pinterest的机器学习不仅采用多模态方法，利用图像、文本和图信号作为输入，还需要在非常大的规模下运行，并且经常需要在实时交互式用户体验中运作。
Pinterest以积极、鼓舞人心的网络环境而闻名，我们认为灵感始于代表性与归属感。负责任的AI团队致力于确保我们的AI系统在设计和部署过程中符合伦理标准，尊重用户隐私，并促进公平性。团队成员来自不同的背景，拥有多样化的视角，共同推动负责任的AI实践。

At Pinterest, AI isn't just a feature, it's a powerful partner that augments our creativity and amplifies our impact, and we’re looking for candidates who are excited to be a part of that. To get a complete picture of your experience and abilities, we’ll explore your foundational skills and how you collaborate with AI.
Through our interview process, what matters most is that you can always explain your approach, showing us not just what you know, but how you think. You can read more about our AI interview philosophy and how we use AI in our recruiting process here.
The Responsible AI team is part of the Advanced Technologies Group (ATG), Pinterest’s advanced machine learning team. ATG’s goal is to keep Pinterest at the forefront of machine learning technology across multiple use cases including recommendations, ranking, content understanding, and more. It is an applied team that works horizontally across the company on state of the art AI and ML and works on directly bringing that technology to the product in collaboration with product engineering teams. The team also publishes its work in applied research conferences, but the main goal of the team is to have a direct impact on business metrics.
At Pinterest our goal is to inspire pinners (our users) to live the life they love. The product is powered by state of the art ML algorithms which are used to understand both the billions of visually rich items on the platform and the interests of our 535M+ monthly active users and recommend inspiring personalized content to them. What this means is that ML at Pinterest is not only multi-modal utilizing image, text, and graph signals as input, but it needs to operate at a very large scale and often in a real time interactive user experience.
Pinterest is known for being a positive and inspirational place on the internet and we believe that inspiration begins with representation and belonging. The Responsible AI team is a horizontal team that collaborates across the company on various initiatives. These range from Generative AI alignment, evaluation, and mitigations - ensuring these models are safe, bias-free, and aligned with Pinterest’s vision and policies - to championing ML Fairness and developing user-facing features that enhance our product for all users. This includes launching groundbreaking features such as user-controllable skin tone, hair pattern search refinements, and more recently, body type.
You’ll help shape forward-thinking projects, develop advanced ML approaches rooted in fairness and equitability, and pioneer responsible AI safeguards for emerging technologies. By joining this team, you’ll make a lasting impact on our Pinners, our business, and the evolution of ethical AI at Pinterest.
What you'll do:
- execute on projects in the responsible AI frontier, to identify, avoid, and mitigate bias across a wide range of ML applications at Pinterest including generative AI.
- Collaborate with other engineering teams (trust and safety, user modeling, content understanding,) to leverage their platforms and signals and work with them to collaborate on the adoption and evaluation of Responsible AI practices and ML Fairness tooling across Pinterest.
- Mentor junior engineers on the Responsible AI team and across the company on the R-AI space.
- Work with the team and senior leaders at the company to define and drive technical strategy in this area.
What we're looking for:
- Extensive, real-world experience applying advanced ML methods to production systems, with a strong track record in responsible technology - spanning fairness, ethics, and broader societal considerations.
- Deep familiarity with cutting-edge ML architectures (e.g., transformer-based models, 2-tower architectures, LLMs) and their applications in large-scale Search and Recommender Systems.
- Proven ability to measure, deploy, and refine fairness interventions and broader Responsible AI solutions at scale, bridging state-of-the-art research with tangible product impact.
- 2+ years working experience in the engineering teams that build large-scale ML-driven user-facing products
- Masters or PhD in Comp Sci or related fields
Nice to have:
- Publications at top ML conferences
- Experience using Cursor, Copilot, Codex, or similar AI coding assistants for development, debugging, testing, and refactoring
- Familiarity with LLM-powered productivity tools for documentation search, experiment analysis, SQL/data exploration, and engineering workflow acceleration
- Expertise in scalable realtime systems that process stream data
- Passion for applied research and the Pinterest product
