Baseten is an AI inference platform serving leading companies like Cursor, Notion, Abridge, and Writer. The company recently raised $1.5B in Series F funding and is building the infrastructure that enables developers to run cutting-edge AI models in production. As one of the first engineers focused on Partner Engineering at Baseten, you will build the technical foundation for strategic partnerships across the AI ecosystem. You'll work directly with engineers at model labs, hyperscalers, developer platforms, and infrastructure companies to turn partnerships into products that developers can use. Key responsibilities include: - Lead strategic partner integrations from technical discovery and architecture through implementation, launch, and production operation. - Integrate new capabilities into Baseten (e.g., search providers, developer tools) so agents can call services during inference with consistent authentication, execution, failure handling, observability, and usage reporting. - Take Baseten into new distribution channels by integrating with hyperscalers, cloud marketplaces, or developer platforms so customers can discover and run models through partner products. - Launch models with leading model labs by building infrastructure for model discovery, access controls, usage attribution, metering, and systems supporting commercial agreements like revenue sharing. - Create reusable partner-platform primitives across identity, provisioning, inference, model serving, metering, billing, and other platform capabilities. - Work directly with partner engineering teams to design APIs, define system boundaries, resolve cross-company dependencies, and make architectural decisions. - Write substantial production code and own the systems you build. - Own technical delivery across Baseten and partner teams, including milestones, dependencies, risks, and architectural tradeoffs. - Work closely with Partnerships and Product to understand ecosystem direction and translate opportunities into platform investments. - Raise the bar for integration reliability through 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, with ability to explain architectural choices and how they meet customer needs at scale. - Track record of leading ambiguous engineering projects across teams while contributing substantial production code yourself. - Sound judgment about API design, service boundaries, and failure handling; experience building systems that uphold API contracts and meet measurable service-level objectives that customers and partners depend on. - Experience turning requests from customers, partners, or other engineering teams into defined technical scope; ability to explain constraints, propose alternatives, and document decisions. - Comfort working across application code and cloud infrastructure, including debugging behavior that crosses service boundaries. Nice to have: - Product integrations with cloud providers, developer platforms, or other infrastructure companies. - Usage metering, marketplace infrastructure, or commerce systems supporting relationships among multiple parties. - Model serving or other AI infrastructure used in production.
