Product Engineer, Internal Tools & Platform in London

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the role

Anthropic is looking for product engineers to build internal products. This role sits at the intersection of engineering, product, and design—you'll own outcomes, not just tasks. You'll work directly with users to understand their needs, identify the patterns behind their requests, and build the right abstractions that unlock capabilities for everyone.

What you'll do:

• Rapidly design, prototype, and ship full-stack features across backend, frontend, and infrastructure
• Consult with users and stakeholders to understand workflows and identify the highest-impact opportunities
• Spot patterns across user requests and reduce them into primitives, platforms, or middleware that support a variety of use cases—not just one-off features
• Build tools that maximize autonomy and creative freedom for less-technical users
• Make product and prioritization decisions, not just execute on specs handed to you
• Iterate quickly based on feedback to continuously improve the user experience
• Pick up new tools, frameworks, and domains as the product evolves

You may be a good fit if you:

• Have 6+ years of experience building production software, ideally full-stack
• Can operate as a team of one when needed—you're independently capable of taking a product from idea to shipped, even if you won't always work that way
• Think in systems and abstractions—you see the platform behind the feature request
• Care about empowering users, not just building for them
• Own outcomes, not just code—you care whether the thing you built actually solved the problem
• Are comfortable making decisions with incomplete information and operating with ambiguity
• Hold yourself to a high bar without needing external pressure

Strong candidates will have:

• Proficiency across the stack (we use Python, TypeScript, React)
• Experience building platforms, primitives, or internal tools that others build on top of
• A track record of shipping products independently—not just contributing to larger efforts

Deadline to apply: None. Applications will be received on a rolling basis.

Your safety matters to us. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from official addresses.

Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day.

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
