Staff+ Software Engineer, Consumer

About the role

We're a small zero-to-one team at Anthropic building brand new consumer AI products. Our mandate: put the full power of frontier Claude models in people's hands, in products that don't exist yet. You'd be a founding engineer, and engineers here own products end to end. You won't be handed a spec. You'll come up with the bet, shape a vague idea into the leanest real version one, and ship it.

Key responsibilities

• Originate new consumer AI product bets and own them from first idea to launch
• Spot the gap between what Claude can do and what people actually experience, and bring the bet: what to build, why now, and the cheapest way to test it
• Take a vague direction and cut it down to the leanest real version one
• Set technical direction for the products you build
• Own the quality bar for how the product looks and feels, treating latency, responsiveness, and reliability as first-class concerns
• Partner with privacy, security, legal, design, platform teams and external partners to find a path to launch
• Iterate quickly based on user feedback and internal testing
• Keep pushing new products over the line, since most zero-to-one bets don't work the first time

Minimum qualifications

• Experience building consumer-facing products, with a strong emphasis on product quality and user experience
• Experience taking a consumer product from nothing to real users
• Proficiency in React, Next.js, and TypeScript
• Backend experience with Node.js

Preferred qualifications

• 5+ years of experience building consumer-facing products, with a strong emphasis on product quality and user experience
• Experience founding a company, being on a founding team, or being an early engineer on a new consumer product
• Experience with products that have real-time or streaming interactions (chat interfaces, live updates)
• Experience optimizing performance for consumer web apps, from bundle size and rendering to end-to-end latency
• High agency: you pick a bet and own it without a roadmap
• Relentlessness: you keep going when a bet fails, verify instead of assume, and stay curious rather than frustrated
• Product taste: you care a lot about product craft, and you know what you'd refuse to ship
• Unusually high EQ: you understand other teams' constraints, seek out collaborations that create value for both sides, and can work with any team at Anthropic
• Willingness to pick up slack, even if it goes outside your job description
