Senior Developer, Partnerships Engineering

The Partnership Engineering team owns the engineering surface area required to make external partnerships and integrations successful, from early Strategic Partnerships discussions through GA launch. The team sits at the intersection of product, platform, and external partners, working across new platform systems, Developer Platform capabilities, browser integrations, and SDK surfaces to ensure integrations are secure, extensible, and built to last. As a Senior Developer on this team, you'll design and build the integration patterns, components, and tooling that power high-impact external partnerships, work directly with partners during active integrations, and help turn one-off deals into reusable capabilities. This is a senior individual contributor role with broad scope: you'll operate independently, shape technical direction within integrations, and influence platform evolution based on real-world partner needs.

Responsibilities

• Lead technical design and implementation for complex external integrations spanning SDKs, service accounts, browser surfaces, and AI-native platforms.
• Partner closely with the Strategic Partnerships team to validate feasibility, assess partner architectures, and shape practical integration approaches.
• Build and extend platform components required to support in-flight integrations.
• Identify common integration patterns and abstract them into reusable infrastructure.
• Produce clear technical artifacts (design docs, sequence diagrams, integration guides) that support internal alignment and partner execution.
• Improve self-service documentation and tooling so integrations become increasingly plug-and-play.
• Support partner migrations to new platform capabilities, including systems with auditing and policy controls.
• Use focused POCs to de-risk new integration patterns, including integrations with external AI platforms and model providers, and inform platform investments.

Qualifications

• Strong backend or full-stack engineering experience building APIs, SDKs, platform capabilities, and integrations with AI-native technologies (LLM APIs, agent frameworks, embeddings, or retrieval systems).
• A track record of delivering complex integrations across organizational boundaries.
• Comfort engaging directly with external technical stakeholders and representing engineering decisions clearly.
• Experience designing secure systems, including authentication, authorization, and policy-driven access models.
• Ability to reason about partner architectures and translate them into pragmatic integration designs.
• Clear technical writing and documentation skills, plus a strong ownership mindset that drives work forward without waiting for perfect clarity.
• Sound judgment on when to build reusable infrastructure versus solving a narrow partner need.
• Experience building or maintaining developer platforms or SDK ecosystems; familiarity with browser integrations or extension architectures is a plus.
