About this role

**ABOUT BASETEN** Baseten powers mission-critical inference for the world's most dynamic AI companies (e.g., Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma, Writer). By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we help frontier AI companies bring cutting-edge models into production. We’re growing quickly and recently raised our **$1.5B Series F**. Join us and help build the platform engineers turn to ship AI products. **THE ROLE** Baseten sits at the center of the AI ecosystem—connecting model labs, hyperscalers, developers, and the tools agents use. **Partner Engineering** is how we connect those worlds. As one of the first engineers focused on **Partner Engineering**, you’ll build the technical foundation behind strategic relationships. You’ll work directly with engineers at model labs, hyperscalers, developer platforms, and AI infrastructure companies to turn partnerships into products developers can actually use. You don’t need a previous partner engineering title—just a strong interest in working closely with another company’s technical team and carrying the resulting product decisions into production at Baseten. **WHAT YOU’LL BUILD** - **Bring new capabilities into Baseten:** Integrate a search or developer-tools provider so an agent can call the service during inference with consistent authentication, execution, failure handling, observability, and usage reporting. - **Expand distribution channels:** Integrate Baseten with a hyperscaler, cloud marketplace, or developer platform so customers can discover models, provision access, and run inference through a partner’s product while Baseten handles serving infrastructure. - **Launch models with leading model labs:** Build infrastructure for developers to discover and run a model lab’s newest models on Baseten, including access controls, usage attribution, metering, and support for commercial agreements (e.g., revenue sharing). - **Create the partner platform:** Identify shared primitives across integrations and turn them into reusable platform capabilities—so we can launch increasingly sophisticated partnerships without reinventing the stack. **WHAT YOU’LL OWN** - Lead strategic partner integrations end-to-end: discovery, architecture, implementation, launch, and production operations. - Collaborate with partner engineering teams to design APIs, define system boundaries, resolve dependencies, and make architectural decisions. - Write substantial production code and own the systems you build. - Build reusable partner-platform primitives across identity, provisioning, inference, model serving, metering, billing, and other Baseten platform capabilities. - Own technical delivery across Baseten and partner teams (milestones, dependencies, risks, and tradeoffs). - Partner with Partnerships and Product to understand ecosystem direction and translate opportunities into platform investments. - Improve integration reliability via strong API contracts, testing, observability, safe rollouts, and thoughtful failure handling. - Help define what Partner Engineering becomes at Baseten as the team and ecosystem grow. **REQUIREMENTS** - Experience designing, shipping, and operating large-scale distributed systems in production. - Proven ability to lead ambiguous engineering projects across teams while contributing substantial production code. - Strong judgment on API design, service boundaries, and failure handling. - Experience scoping technical
