Clear Fracture hiring Senior Software Engineer (Auth & Identity) in United States | LinkedIn

Clear Fracture is inventing a new class of AI-driven data integration platforms, enabling organizations to securely connect and operationalize data across complex environments. Our platform uses multi-agent systems to automate data integration, analysis, and operational workflows for mission-critical government and enterprise applications. We are seeking a backend focused Senior Software Engineer to design and build the authorization and identity systems embedded directly within our product. This is a hands-on engineering role focused on implementing fine-grained access control, authentication flows, and tenant-aware security mechanisms across our platform. You won't just be managing an identity provider; you'll be designing and coding the high-performance authorization middleware and SDKs that allow autonomous agents to navigate sensitive data pipelines securely. If you enjoy solving complex distributed systems problems where 'standard' cloud-based solutions don't work, this is your role. You will work closely with backend, platform, and DevOps engineers to integrate authorization into core application workflows, APIs, and agent systems. This role is ideal for engineers who enjoy building security-critical systems in production code, not just configuring or operating infrastructure. Note: This is not a DevOps or infrastructure security role. It focuses on building application-layer authorization and identity systems.

4+ years of experience building authorization, identity, or authentication systems in application code. Strong backend software engineering experience (e.g., Python, Go, Java), including: Designing APIs, Implementing authentication flows, Enforcing authorization in service logic. Deep understanding of: RBAC, ABAC, and/or policy-based access control models, OAuth2, OpenID Connect (OIDC), SAML, and enterprise SSO. Experience designing or implementing fine-grained permissions in complex or distributed systems. Experience working on multi-tenant applications or systems with strong isolation requirements. Familiarity with threat modeling and secure system design, especially around access control and trust boundaries. Comfortable working in a collaborative engineering environment and integrating security into shared codebases. Experience building or deploying systems in cloud environments. (AWS, Azure, or GCP) Strong communication skills and ability to explain technical concepts clearly. Bachelor’s degree in Computer Science or equivalent practical experience. Due to the nature of the work, U.S. Citizenship and the ability to obtain a Secret Clearance are required.
