Product Engineer (Frontend)

At SafetyKit, we use language models to tackle real-world trust and safety challenges for some of the world's leading companies. Our technology helps teams build, refine, and enforce complex policies (think regulated goods, brand guidelines, and everything in between).

We work for payment processors and marketplaces including Upwork, Faire, Patreon, Character.ai, Substack, and Eventbrite. We built a product our users love—now they want more. We’re growing fast to meet demand and we need talented engineers to help shape the next generation of AI-powered trust and safety.

You are thoughtful, opinionated, and fast. You can own the product pipeline, from user interviews to design to pushing code that the engineering, policy, and operation teams using SafetyKit will love. You can center a div 7 different ways (or know how to get Cursor to do it).

Responsibilities

• Owning product features end to end: from user research and design to shipping production code
• Build fast and reliable infrastructure (LLM evaluation, web crawling, document ingestion, etc.) that protects organizations and their end users
• Creating beautiful and performant user interfaces for operations, engineering, and policy teams
• Getting to know our users and their policies deeply: understanding what they care about, then building language model decision flows that capture those complexities
• Quickly experimenting with and deploying new AI technologies. Newly deployed vision model lands that outperforms the state-of-the-art? We need to test, integrate, and ship it today

Your skills

• You’re fast and confident in Typescript, React and Next.js (or able to get there quickly)
• You're familiar with Postgres, SQL, and serverless AWS services like Lambda and Step Functions
• You have high empathy, love talking to users, and learning about their weird and complex business problems
• You’re excited to work together in our San Francisco office five days a week

Bonus Points

• Prior experience as an early/founding engineer at a start-up
• Experience with language models and vision models

We keep our interview process minimal:

• 15min intro call with our founders to talk about your background and for us to pitch you on SafetyKit
• 30min remote coding interview (think Leetcode)
• On-site in our office in San Francisco. Meet the team, do some architecture white boarding, draw some boxes, and do some more coding
• We make decision/offer the day of your onsite
