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 high-impact external partnerships, working closely with partners and contributing to shared infrastructure.
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
