Senior Developer, Partnerships Engineering

1Password is a rapidly growing company recognized for its innovative cybersecurity solutions. The Senior Developer on Partnership Engineering will design and build integration patterns and tooling for external partnerships, ensuring secure and scalable integrations.

Responsibilities:

• Lead technical design and implementation for complex external integrations spanning SDKs, service accounts, browser surfaces, new platform systems, 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
• Contribute to the external integrations program, including tracking lifecycle progress from initial discussion through GA
• Produce clear technical artifacts (design docs, sequence diagrams, integration guides) that support both 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 new platform systems-based 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

Requirements:

• 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
• Strong ownership mindset you drive 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
• Experience migrating systems to new platform primitives or security models
• Hands-on experience integrating with external AI companies or AI-native technologies such as LLM APIs, agent frameworks, embeddings, or retrieval systems
