Staff+ Software Engineer, Platform Ecosystem

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.

We are looking for experienced software engineers to join the Platform Ecosystem team within our Platform organization. Platform Ecosystem exists to empower the next big industries to build on Claude and to create the commercial rails that let businesses building on our platform flourish. This is a founding team, and you'll play a critical role in accelerating AI transformation across highly impactful, mission-driven sectors.

You'll drive 0 → 1 efforts from ideation through delivery, partner closely with product, design, research, and forward-deployed engineers, and bring strong product and business sense to shape our strategy in entirely new domains. You should be comfortable moving across a breadth of different stacks and going deep when needed to break through walls and turn ambiguous opportunities into high-quality, shipped products.

The Ecosystem team is organized around two pillars. Placement takes into account your interests and experience alongside organizational needs, so you can land where you'll have the greatest impact and growth potential.

Verticals: We build for the next API markets, such as Life Sciences & Healthcare. You'll work alongside product, design, research, and forward-deployed engineers to understand what these industries need from Claude, and build the capabilities, integrations, and workflows that let them adopt Claude safely and at scale. Expect to move quickly across unfamiliar domains, learn what matters to each market, and ship products that unlock entirely new categories of customers on the platform.

Monetization: We build the commercial rails and controls that let the platform do business anywhere, with anyone — and turn Claude from a cost line into a revenue line. You'll design and operate the systems that let businesses building on Claude price, package, and sell what they build, and give them the controls they need to do so with confidence. This work sits at the intersection of product, platform infrastructure, and go-to-market, and it directly shapes how the ecosystem around Claude grows.

• Have a minimum of 8 years of practical experience as a backend or platform engineer, along with some frontend experience

• Have strong product sense and the technical chops to tackle a wide variety of challenges, and are great at working closely with cross-functional partners to ideate and execute product strategy in new domains

• Are familiar with using AI tools as part of the software development process

• Take a product-focused approach to platform work and care about building solutions that are robust, scalable, and easy to use

• Take full ownership of your work — from design through build, deployment, and operations, to iterating on and improving your product

• Can navigate ambiguity and make sound technical decisions independently, and have ideally operated in both 0 → 1 and more mature team or company settings

• Care about building systems that other engineers and businesses love to use

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

Location Preference: Preference will be given to candidates based in NY, SEA, SF or the Bay Area given the current location of team.
