Software Engineer (Labs)

• At Anthropic, we’re building AI systems that are safe, beneficial, and transformative
• Our mission is to develop AI that benefits humanity, and we believe the most powerful capabilities emerge when we thoughtfully bridge the gap between research breakthroughs and real-world applications
• Anthropic Labs serves as our internal accelerator
• We’re looking for the next breakout hits that bring substantial revenue or transform an industry
• We operate in close partnership with research and build through fast iteration cycles
• Past successes include Claude Code and MCP
• We’re seeking versatile, entrepreneurial engineers to join Labs
• In this role, you’ll work at the intersection of cutting-edge research and real-world application, rapidly building and testing new experiences, working directly with researchers and users, and generating the insights that shape Anthropic’s product future
• Rapidly prototype full-stack applications that showcase emerging AI capabilities, shipping early and often to maximize learning
• Collaborate closely with research teams to understand new model capabilities and translate them into intuitive user experiences
• Work directly with internal test users and external partners to gather feedback, iterate quickly, and validate (or invalidate) product concepts
• Design and run structured experiments to test hypotheses, balancing creative exploration with rigorous evaluation
• Generate documentation and insights to guide successful prototypes toward full product teams
• Advocate for user experience and product considerations early in the research process
• Provide feedback to research teams about model effectiveness and where capabilities can be improved
• Flexibly contribute across Labs initiatives based on organizational priorities and emerging opportunities—context from one project should inform the next

• Home office stipends
• Relocation support for those moving for Anthropic
• Daily meals and snacks in the office- You’ll need to be comfortable with ambiguity, willing to kill your own projects when the data says to, and energized by the pace of building in uncharted territory
• Are a generalist who can transition between different problem spaces as priorities shift
• Can articulate learnings from failed or killed projects without defensiveness; you treat your work as experiments
• Work independently with good judgment about what matters, without needing constant direction
• Have strong technical skills across modern web development stacks (React, Node.js, Python, etc.) and are comfortable with APIs, databases, and cloud technologies
• Have a hacker mentality: high agency, bias toward shipping, comfort with technical debt when it’s the right tradeoff
• Thrive in ambiguity and are energized (not anxious) by uncertainty—you’re comfortable working on projects that might not exist in three months
• Care about the societal impacts and ethics of your work
• Are deeply user-centric—you validate ideas with actual users before over-investing and talk about problems before solutions
• Have 8+ years of experience building full-stack applications, with a track record of zero-to-one work in startup or startup-like environments
• Communicate effectively and translate complex AI capabilities into intuitive experiences
• Hold strong opinions loosely—you advocate forcefully for ideas but change your mind based on evidence
• Experience across both B2B and B2C product development, or in multiple industries
• We encourage you to apply even if you do not believe you meet every single qualification
• Experience with real-time applications, WebSocket implementations, or complex frontend interactions
• Not all strong candidates will meet every single qualification as listed
• Design sensibility or hands-on experience with UI/UX for AI-powered applications
• Experience building products that involve AI/ML components or working with large language models
• Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you’re interested in this work
• Background conducting user research, interviews, and usability testing
• We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team
• We think AI systems like the ones we’re building have enormous social and ethical implications
• Experience collaborating directly with research teams in AI/ML environments
